THE SENTRY Reviews
Started as a single project and earned a permanent spot on our preferred vendor list
Morgan Ellsworth / Head of Digital Health | Jun 10, 2026What actually moved the needle wasn't their ability to follow a spec — any competent team can do that. It was their willingness to push back when a requirement didn't make sense, explain clearly why, and help us decide on something better instead. That extra layer of judgment took the final product past what we'd actually asked for and closer to what we genuinely needed, which isn't always the same thing.
Project summary
Our actuarial models had outgrown the reporting pipeline feeding them, and the resulting data lag was introducing real risk into pricing decisions the business wasn't comfortable carrying anymore.

Questions & Answers
Accessibility work broadened our reach and impressed clients we didn't expect it to matter to
Rodrigo Cardoso / VP of Technology | Jun 09, 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
Portal usability complaints were showing up disproportionately among the B2B accounts we were about to lose at renewal. The self-service experience needed a full rebuild before that cycle hit.

Questions & Answers
Treated our product's quality like it was their own reputation on the line
Wei Ling Ong / VP of Engineering | May 28, 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.

Questions & Answers
Handled twelve times normal traffic on our biggest sale day without a hiccup
Anton Berggren / Chief Technology Officer | May 10, 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
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
Got the outcome we asked for, delivered the way we needed it, by people we'd hire again
Henrik Schuster / VP of Technology | Apr 30, 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
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.

First time our online and in-store inventory have shown the same numbers
Hamza Farooqi / Co-Founder & CTO | Mar 24, 2026What actually moved the needle wasn't their ability to follow a spec — any competent team can do that. It was their willingness to push back when a requirement didn't make sense, explain clearly why, and help us decide on something better instead.

Project summary
Buyer behavior had gone fully digital-first and our search experience had quietly become a liability. It needed to match the quality of the listings it was supposed to represent.

Questions & Answers
Gave us an honest read of where we stood, then a credible plan to move from there
Soo-Ah Yoon / Director of Platform | Feb 13, 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 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.

Our SRE team now points new hires to this setup as the reference example

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.
