Please describe your company, your role, and the industry you operate in.
As Chief Technology Officer at Delta Tech BV I oversee technology spend and delivery across our Energy & Utilities operations out of Rotterdam, Netherlands. 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 IoT 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?
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?
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?
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.
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 Energy & Utilities network, both times to people facing IoT 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.
