Killer Mobile Software Reviews
Outperformed our old in-house desk on every SLA metric we track
Anjali Raghunathan / VP of Data Science | Jun 02, 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
This project had a board-facing deadline tied to a wider strategic push. We needed a partner who'd treat that date like it was their own problem, not just ours.

Questions & Answers
Went from whitepaper to mainnet without a single incident worth mentioning
Preston Locke / Director of Technology | May 09, 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
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.

Questions & Answers
Their pen test found gaps our previous vendor had missed two years running
Mahnoor Sheikh / Head of Technology | May 08, 2026We 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
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.

Delivered with the change management and documentation a project this size actually needs
Airi Kobayashi / Head of Product Development | Feb 18, 2026This was our fourth agency in three years, and I say that with some embarrassment.

Project summary
Our headcount had grown faster than our platform engineering depth. We needed an experienced team to close that gap while we hired, without letting quality or the roadmap slip in the meantime.

Questions & Answers
The rebuilt site went from something we apologized for to something our sales team leads with
Nicolas Fontaine / Directeur Technique | Feb 16, 2026We 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 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.

Questions & Answers
Delivered with the change management and documentation a project this size actually needs
Kenji Watanabe / Director of IT Strategy | Feb 15, 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
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.

Collapsed a two-week release cycle down to same-day deployments
Faisal Al-Dosari / Head of Innovation | Feb 06, 2026Going in, the integration work was what worried me most.

Project summary
Our product thinking internally was solid, but our execution depth in this particular technical domain wasn't. We needed real specialists, not another generalist team.
