Gridstone Reviews
Monetization was integrated in a way players tolerated rather than resented
Anton Berggren / Chief Technology Officer | Jun 06, 2026The 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
Years of incremental patches had left us with a platform that technically worked but was quietly holding the business back strategically. A proper rebuild was the agreed way forward.

Questions & Answers
Built for real-world constraints, not just for how it would read in a pitch deck
Amal Al-Hosani / Head of Digital Strategy | May 18, 2026I 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
Warehouse errors were becoming visible to clients, not just internal reporting. A modernized WMS was already the agreed direction internally — we just needed someone to actually build it.

Questions & Answers
Solved a trust problem between our partners that we'd been arguing about for three years
Griffin Ashcombe / Managing Director, Tech | Apr 20, 2026Going in, the integration work was what worried me most. Our systems landscape is messy, a couple of the third-party APIs we depend on are barely documented, and one of those vendors has a well-earned reputation for slow, inconsistent support. This team absorbed all of that. They documented what the upstream providers wouldn't, built in resilience wherever the upstream behavior was flaky, and shipped something that has worked exactly as specified since go-live. I genuinely couldn't have asked for more on that front.
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.

Questions & Answers
Delivered the sales visibility we'd been requesting internally for three years, in fourteen weeks
Larissa Nogueira / Chief Digital Officer | Apr 18, 2026Five months post-launch, we're running at roughly double the transaction volume we'd specified in the original scope document, and the platform hasn't needed a single structural change to handle it. That's the real tell for whether a team designed for what you told them versus what you were actually going to need. We're now scoping a second phase and I expect this to be a multi-year relationship at this point.
Project summary
First notice of loss was taking us three days on average against a market benchmark of under four hours. Automating that intake and triage step became the clear priority.

Closed the operational blind spots we'd been working around for longer than we'd like to admit

Project summary
Our client portal hadn't been touched since it launched years earlier, and clients had started comparing it unfavorably to competitors' portals in live pitches.

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

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.

Project summary
Multi-touch attribution across our media mix was the single most requested capability from clients across our whole portfolio, and we couldn't deliver it without rebuilding the data layer underneath.

Questions & Answers
Custom build that quietly replaced three separate off-the-shelf tools we were juggling before
Aoibhinn Molloy / Director of Product | Jan 28, 2026I 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
A previous project had worked fine in staging and fallen apart in production. We approached vendor selection this time with a lot more scrutiny as a direct result.

Questions & Answers
Execution matched the proposal on every dimension that actually mattered to us
Mahnoor Sheikh / Head of Technology | Jan 18, 2026This 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
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.
