NS804 Reviews
Treated our product's quality like it was their own reputation on the line
Karthik Iyengar / Head of Platform | Jun 08, 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
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
The research surfaced friction points we'd stopped noticing because they'd always been there
Henrik Schuster / VP of Technology | May 20, 2026We 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
New digital service standards required every citizen-facing application to hit accessibility and performance benchmarks our legacy systems simply couldn't reach. Patching them wasn't realistic.

Questions & Answers
Modules built around how we actually operate instead of forcing us to change our process
Anton Berggren / Chief Technology Officer | May 15, 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
Our internal engineering capacity was fully committed to keeping existing systems running, with no room for a build of this size. An outside partner with the right depth was really our only option.

Designed around how our users actually behave, not the persona slide we'd been assuming
Soo-Ah Yoon / Director of Platform | Mar 06, 2026We 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
Audience data was scattered across eight different tools with no shared identity layer. Personalization was never going to work until that foundation got fixed first.

Questions & Answers
First time our online and in-store inventory have shown the same numbers
Margaux Lefèvre / Head of Digital Products | Mar 05, 2026Looking back, the thing that stands out most is how uneventful the whole project was. Technology projects of this size tend to generate their share of fire drills and awkward escalation calls. This one really didn't. Issues got flagged early enough that they never became incidents, scope changes went through an actual process instead of a tense phone call, and risks were tracked rather than just hoped away. That kind of quiet competence is unusual in my experience, and it made the whole thing feel easier on our end than I know it was on theirs.

Questions & Answers
Passed our biggest enterprise client's security questionnaire on the first submission
Agnieszka Zielińska / CTO | Jan 29, 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
Dynamic pricing had been run manually for years. We knew the revenue upside was real but had no in-house way to build the models and wire them into the booking engine.

A merger left us running two incompatible student information systems. We needed a consolidation plan that kept historical records intact and didn't interrupt term-time operations.
