Core Web Vitals scores validated every performance decision they pushed us to make

Karthik Iyengar / Head of Platform | Jun 04, 2026

The easiest thing to praise is the technical output itself — solid test coverage, a deployment pipeline that just works, documentation that people actually reference instead of ignoring. But what I keep coming back to is the number of conversations we haven't had to have since launch. No 2am incident calls. No emergency patches. No post-mortems about what went sideways. That absence is really the whole pitch, if you ask me.


Project summary

A licensing deal had handed us a major catalogue, but our streaming infrastructure couldn't deliver it reliably at scale. We needed a cloud-native video platform inside of six months.

Questions & Answers

Please describe your company, your role, and the industry you operate in.
As Head of Platform at Novus EdTech Solutions I oversee technology spend and delivery across our Media & Entertainment operations out of Coimbatore, India. We're a commercially minded business, so every technology decision gets judged on what it actually contributes to the bottom line, not on how elegant it looks on paper.
What specific problem or business challenge led you to hire this company?
Our previous vendor had maintained this platform for a few years, and the technical debt had piled up to the point where our delivery speed had dropped to a fraction of what it used to be. We needed fresh engineering eyes and an actual plan to deal with the underlying mess.
What services did the company provide for your project?
The scope ran the full Web Development lifecycle — discovery, requirements, architecture, development across roughly a dozen sprints, integration testing, performance validation, deployment, and a four-week hypercare window afterward. They also handed over full documentation and ran a knowledge transfer session for our internal team.
Why did you choose this company over other providers you considered?
A peer in the Media & Entertainment space had used them for something similar in Web Development and recommended them without hesitation. Our own due diligence backed that up. Domain knowledge, Web Development depth, and a track record of actually delivering — that combination made the decision easy.
How clearly did the company understand your requirements and business goals?
Better than we understood them ourselves, honestly. The workshops they ran surfaced assumptions we'd never questioned and exposed a few requirements that flatly contradicted each other. Sorting that out before development started saved us from what would have been serious rework later.
How was your overall experience with their communication and project management?
Genuinely excellent, especially given the time difference between Coimbatore, India and the delivery team. Written updates were consistent and specific, anything needing a decision got same-day turnaround, and nothing slipped through the cracks across the whole engagement.
Did the company deliver the project on time and within your expected budget?
Yes to both. I'd quietly built in some contingency given the complexity and the number of integrations involved, and none of it ended up being needed. Delivery landed on the agreed date and the final invoice was within a rounding error of the approved budget — rarer than most people in this industry would admit.
What tangible results or business impact have you seen since the project was completed?
Hard to isolate perfectly given everything else going on in the business, but the numbers we can attribute directly to the Web Development work are solid: session duration up, conversion up, error rate down, and our NPS for that touchpoint has moved noticeably. Our account managers say it's coming up positively in client conversations now too.
What did you like most about working with this company?
The team stayed the same the whole way through. The engineers in the discovery sessions were the same ones who built the system. That continuity matters more than people expect, and you really only notice it when it's missing. Every conversation picked up where the last one left off.
Would you recommend this company to others, and would you work with them again?
Yes, no hesitation. I've already referred them twice within my own Media & Entertainment network, both times to people facing Web Development problems similar to ours. I made those referrals confidently because I know the experience I had was repeatable, not a one-off stroke of luck on our project.

Core Web Vitals scores validated every performance decision they pushed us to make

Elin Holmqvist / Head of Product Engineering | Feb 28, 2026

We had proposals in hand ranging from roughly half to well over double what we eventually paid this team. What set their proposal apart wasn't the price — it was that the number matched what they actually delivered, almost line for line. I've been burned before by proposals that were really just opening offers in a negotiation that continues throughout the project. That wasn't the case here, and I don't say that lightly.


Project summary

Our funnel data made it obvious exactly where we were losing customers, and it wasn't subtle. We needed a platform capable of the experience our competitors were already delivering.

Questions & Answers

Please describe your company, your role, and the industry you operate in.
Vinter Digital AB has been operating in Retail & E-commerce for a while now, headquartered in Uppsala, Sweden. As Head of Product Engineering I sit across both strategic planning and day-to-day technology delivery. We hold our vendors to a high bar because our own clients hold us to one — it's only fair to expect the same discipline from partners.
What specific problem or business challenge led you to hire this company?
Regulation in our Retail & E-commerce segment shifted and the compliance deadline came from the regulator, not from us. The scale of the Web Development changes required justified bringing in a specialist rather than pulling our internal team off the product roadmap to handle it.
What services did the company provide for your project?
Mainly Web Development, with some adjacent architecture and QA work folded in. They owned the whole thing from requirements to go-live, including hooking it into four of our existing systems. Not needing a second vendor to cover that ground was genuinely useful, both cost-wise and logistically.
Why did you choose this company over other providers you considered?
We shortlisted five vendors through a structured process. The technical review knocked two out right away. Of the remaining three, this team stood out because their Web Development approach was specific rather than generic, backed by actual reference projects in Retail & E-commerce — not just case studies pulled off a website. The reference calls confirmed everything the proposal claimed.
How clearly did the company understand your requirements and business goals?
Really well, partly because they already had Retail & E-commerce experience that cut down on the amount of context we had to provide. They knew the terminology, asked the right questions, and translated our business requirements into technical specs accurately enough that development barely needed any clarification cycles.
How was your overall experience with their communication and project management?
Proactive and well-calibrated. Technical detail for the engineering side, plain summaries for the steering group, and risk flags that came with a proposed fix attached rather than just a problem statement. The biweekly sprint reviews kept our stakeholders in the loop without requiring them to sit in on every working session.
Did the company deliver the project on time and within your expected budget?
Yes to both. I'd quietly built in some contingency given the complexity and the number of integrations involved, and none of it ended up being needed. Delivery landed on the agreed date and the final invoice was within a rounding error of the approved budget — rarer than most people in this industry would admit.
What tangible results or business impact have you seen since the project was completed?
We went live about three months ago. User adoption beat the target we'd set by roughly 20 percent in the first month, and support ticket volume has dropped noticeably since. Features we'd shelved because the old architecture made them too expensive to build are now back on the roadmap.
What did you like most about working with this company?
The team stayed the same the whole way through. The engineers in the discovery sessions were the same ones who built the system. That continuity matters more than people expect, and you really only notice it when it's missing. Every conversation picked up where the last one left off.
Would you recommend this company to others, and would you work with them again?
Without reservation. We're already in early conversations about a second engagement, and I expect this to turn into a multi-year relationship. Anyone in Retail & E-commerce looking for real Web Development depth paired with actual delivery discipline should have this team near the top of their list.

Outperformed our old in-house desk on every SLA metric we track

Hamish Bellamy / GM of Technology | Feb 13, 2026

I went into this engagement genuinely skeptical. A previous vendor had left us with a system that technically worked but that nobody trusted, and I wasn't interested in repeating that experience. This team earned trust the slow way — solid discovery documentation, technical proposals that held up under scrutiny, sprints that landed when promised, and ultimately a production system that has simply behaved. I don't open conversations about them with caveats anymore.


Project summary

New traceability legislation brought a hard serialization deadline. Our supply chain system needed targeted, specialist development to meet it — general-purpose expertise wasn't going to cut it.

Project Cost:$10,000 to $49,999
Project Duration:May 2025 - Dec 2025
Business Type:Pharmaceuticals & Biotechnology
Location:Melbourne, Australia

Questions & Answers

Please describe your company, your role, and the industry you operate in.
Tasman Commerce Group is a Pharmaceuticals & Biotechnology business headquartered in Melbourne, Australia. As GM of Technology I'm responsible for the whole technology agenda — infrastructure, product, and how we pick vendors. Every decision we make on the technology side has to tie back to a clear business case before it gets approved.
What specific problem or business challenge led you to hire this company?
Regulation in our Pharmaceuticals & Biotechnology segment shifted and the compliance deadline came from the regulator, not from us. The scale of the IT Managed Services changes required justified bringing in a specialist rather than pulling our internal team off the product roadmap to handle it.
What services did the company provide for your project?
Mainly IT Managed Services, with some adjacent architecture and QA work folded in. They owned the whole thing from requirements to go-live, including hooking it into four of our existing systems. Not needing a second vendor to cover that ground was genuinely useful, both cost-wise and logistically.
Why did you choose this company over other providers you considered?
A peer in the Pharmaceuticals & Biotechnology space had used them for something similar in IT Managed Services and recommended them without hesitation. Our own due diligence backed that up. Domain knowledge, IT Managed Services depth, and a track record of actually delivering — that combination made the decision easy.
How clearly did the company understand your requirements and business goals?
Very well. The discovery phase was more thorough than anything we'd been through with prior vendors. They pushed back on requirements that were vague or contradictory, suggested better alternatives where our own thinking was limited, and produced a spec our internal stakeholders agreed was the clearest version of the product they'd ever seen written down.
How was your overall experience with their communication and project management?
Proactive and well-calibrated. Technical detail for the engineering side, plain summaries for the steering group, and risk flags that came with a proposed fix attached rather than just a problem statement. The biweekly sprint reviews kept our stakeholders in the loop without requiring them to sit in on every working session.
Did the company deliver the project on time and within your expected budget?
On time and inside the approved budget. Their estimating was notably accurate — they'd broken the work down in enough detail during discovery that the forecast held up the whole way through, instead of drifting with every small change. We had exactly one change request, and it was for scope we added ourselves.
What tangible results or business impact have you seen since the project was completed?
We went live about three months ago. User adoption beat the target we'd set by roughly 20 percent in the first month, and support ticket volume has dropped noticeably since. Features we'd shelved because the old architecture made them too expensive to build are now back on the roadmap.

Turned marketing spend from a cost debate into a revenue conversation with leadership

Hamza Farooqi / Co-Founder & CTO | Jan 19, 2026

We handed this team an aggressive deadline, a genuinely complicated scope, and a client-side team on our end that was stretched thin and slow to respond at times. They handled all of it without complaint. When they needed something from us they asked precisely and on time. When they didn't, they just kept moving. The project still landed on schedule despite our side being the weaker link for a good chunk of it, which tells you something about how they operate under pressure.


Project summary

Grid modernization funding required us to prove demand-response capability. The models existed on paper — we needed engineers to actually build and run them in production.

Business Type:Energy & Utilities
Location:Karachi, Pakistan

Questions & Answers

Please describe your company, your role, and the industry you operate in.
Karakoram Software House has been operating in Energy & Utilities for a while now, headquartered in Karachi, Pakistan. As Co-Founder & CTO I sit across both strategic planning and day-to-day technology delivery. We hold our vendors to a high bar because our own clients hold us to one — it's only fair to expect the same discipline from partners.
What specific problem or business challenge led you to hire this company?
Our Digital Marketing capability had become the thing slowing everything else down. New feature requests, client asks, internal initiatives — all of it kept queuing up behind a platform that had been stretched way past what it was originally built for. We needed a proper rebuild, not another patch.
What services did the company provide for your project?
The scope ran the full Digital Marketing lifecycle — discovery, requirements, architecture, development across roughly a dozen sprints, integration testing, performance validation, deployment, and a four-week hypercare window afterward. They also handed over full documentation and ran a knowledge transfer session for our internal team.
Why did you choose this company over other providers you considered?
We were coming off a failed engagement and went into vendor selection this time with a lot more scrutiny. We asked pointed questions about how they handle scope changes, how they estimate, how they communicate bad news. The answers were specific and consistent across everyone we spoke to on their team, which gave us confidence it wasn't a rehearsed pitch.
How clearly did the company understand your requirements and business goals?
Really well, partly because they already had Energy & Utilities experience that cut down on the amount of context we had to provide. They knew the terminology, asked the right questions, and translated our business requirements into technical specs accurately enough that development barely needed any clarification cycles.
How was your overall experience with their communication and project management?
Professional throughout. The project manager always had a clear view of the critical path and flagged changes to it honestly, without spin. The one significant scope change we made mid-project went through a clean process — fairly priced, clearly documented, and absorbed without knocking the rest of the timeline off course.
Did the company deliver the project on time and within your expected budget?
Yes to both. I'd quietly built in some contingency given the complexity and the number of integrations involved, and none of it ended up being needed. Delivery landed on the agreed date and the final invoice was within a rounding error of the approved budget — rarer than most people in this industry would admit.
What tangible results or business impact have you seen since the project was completed?
The clearest measure is how the system's actually performing in production. In the four months since go-live we've had zero major incidents, our page performance scores improved across every Core Web Vitals metric, and two enterprise clients who'd previously flagged our old platform's limits during renewal talks signed again without raising it.
What did you like most about working with this company?
Their willingness to just be direct. If our requirements were unclear, they said so. If our priorities contradicted each other, they explained why. If an approach we'd assumed was right actually had real downsides, they told us before we'd committed to it. That kind of honesty is exactly what I look for in a long-term partner.
Would you recommend this company to others, and would you work with them again?
Yes — though I'll add that they're not the cheapest option out there and they're selective about what they take on. If price is your main filter, look elsewhere. If you need a partner you can trust with a serious Digital Marketing program in Energy & Utilities and expect them to actually deliver against the brief, this is the team.

The return on this investment outpaced the business case we originally approved

Agnieszka Zielińska / CTO | Jan 15, 2026

The easiest thing to praise is the technical output itself — solid test coverage, a deployment pipeline that just works, documentation that people actually reference instead of ignoring. But what I keep coming back to is the number of conversations we haven't had to have since launch. No 2am incident calls. No emergency patches. No post-mortems about what went sideways. That absence is really the whole pitch, if you ask me.


Project summary

The handoff between our clinic system and our patient app kept breaking in the same places. We needed a partner willing to own that integration end to end, not just patch it again.

Location:Poznań, Poland

Questions & Answers

Please describe your company, your role, and the industry you operate in.
As CTO at Bug Tech Studio I oversee technology spend and delivery across our Healthcare operations out of Poznań, Poland. We're a commercially minded business, so every technology decision gets judged on what it actually contributes to the bottom line, not on how elegant it looks on paper.
What specific problem or business challenge led you to hire this company?
Our Industry-Specific Solutions capability had become the thing slowing everything else down. New feature requests, client asks, internal initiatives — all of it kept queuing up behind a platform that had been stretched way past what it was originally built for. We needed a proper rebuild, not another patch.
What services did the company provide for your project?
The core of it was Industry-Specific Solutions, though their involvement grew to include technical consulting during discovery that meaningfully sharpened our own requirements. They also took full ownership of the third-party integration work, which had been a coordination headache on past projects, and just handled it themselves.
Why did you choose this company over other providers you considered?
The questions they asked during the briefing stage told us most of what we needed to know. Vendors who ask sharp questions during sales tend to bring that same rigor into delivery, and that held up. The technical proposal had real substance, the team was senior from the start, and the pricing was straightforward.
How clearly did the company understand your requirements and business goals?
Thoroughly. The requirements document was detailed enough that our own QA team used it directly to build acceptance criteria. Every user story had a clear business reason attached, and nothing was left open to interpretation. That discipline early on paid off through the rest of development and testing.
How was your overall experience with their communication and project management?
The most structured project management I've dealt with from any outside vendor. Sprint planning was tight, acceptance criteria were specific, and retrospectives actually led to changes rather than just being a box to tick. The backlog and risk register were both treated as live tools, not paperwork. I never once had to chase a status update.
Did the company deliver the project on time and within your expected budget?
Both, yes. One sprint hit a one-week delay from a third-party API dependency outside anyone's control. The team flagged it three weeks ahead of time, laid out two options, and we picked an approach that clawed the schedule back within the same sprint. That's the kind of foresight that separates real project management from just reacting to problems.
What tangible results or business impact have you seen since the project was completed?
The clearest measure is how the system's actually performing in production. In the four months since go-live we've had zero major incidents, our page performance scores improved across every Core Web Vitals metric, and two enterprise clients who'd previously flagged our old platform's limits during renewal talks signed again without raising it.
What did you like most about working with this company?
What they did after launch. A lot of vendors treat go-live as the finish line. This team treated it as the start of a different phase — the hypercare period was substantial, the documentation held up in practice, and they checked back in at the thirty and ninety day marks to go over production metrics with us unprompted.
Would you recommend this company to others, and would you work with them again?
Absolutely, with one caveat worth mentioning: the value really starts in discovery, so clients who take that phase seriously will get the most out of it. We put real effort in upfront and it clearly paid off in what got delivered.

Collapsed a two-week release cycle down to same-day deployments

Konstantin Bauer / Leiter Digitalisierung | Jan 13, 2026

This was our fourth agency in three years, and I say that with some embarrassment. Every previous engagement had looked promising on paper and fallen apart somewhere in delivery. What was different here was the sequencing: they spent real time understanding the actual problem before proposing anything, rather than pattern-matching to a solution they already knew how to sell. The build ran to schedule, our own engineers had genuinely positive things to say during handover, and four months into live operation we haven't had a single critical incident. We're already talking about the next phase with them.


Project summary

Remote care had gone from a pilot program to a core part of our business, and our technology hadn't caught up. We needed a compliant telehealth platform on a timeline the market wasn't going to wait for.

Bauer Industrie GmbH is a Healthcare business headquartered in Munich, Germany. As Leiter Digitalisierung I'm responsible for the whole technology agenda — infrastructure, product, and how we pick vendors. Every decision we make on the technology side has to tie back to a clear business case before it gets approved.
What specific problem or business challenge led you to hire this company?
Regulation in our Healthcare segment shifted and the compliance deadline came from the regulator, not from us. The scale of the DevOps Services changes required justified bringing in a specialist rather than pulling our internal team off the product roadmap to handle it.
What services did the company provide for your project?
Full DevOps Services delivery, with particular depth on the integration and data migration pieces — the riskiest parts of the whole program. On top of that, they kept a dedicated QA person on the project throughout and left our operations team with a proper runbook at handover.
