The first CMS rollout where editors asked for more of it, not less
Margaux Lefèvre / Head of Digital Products | May 23, 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
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.

Delivered the sales visibility we'd been requesting internally for three years, in fourteen weeks
Cormac Whelan / VP of Engineering | Apr 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.

Project summary
Our lean manufacturing push needed real-time OEE data at the line level, and our existing systems could only produce it through hours of manual spreadsheet work each week.

Questions & Answers
Custom build that quietly replaced three separate off-the-shelf tools we were juggling before
Hamza Farooqi / Co-Founder & CTO | Apr 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
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.

Multiplayer infrastructure held through a launch-day spike we hadn't fully planned for

Matter management had quietly become a real drag on our fee earners' time — every hour on admin was an hour not spent on billable work. The case for fixing it wrote itself.

Questions & Answers
Our internal teams have genuinely forgotten infrastructure used to be a source of stress
Marcus Teo / CTO | Feb 11, 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 product thinking internally was solid, but our execution depth in this particular technical domain wasn't. We needed real specialists, not another generalist team.

Questions & Answers
Daily active usage on the app has stayed well above what we projected at launch
Wei Ling Ong / VP of Engineering | Jan 19, 2026Our stakeholder list for this project included board members, operations leads, compliance, and end users, all with wildly different levels of technical fluency and different definitions of success. Managing that mix well is genuinely hard, and this team did it better than any vendor we've worked with. They shifted register depending on who they were talking to without ever dumbing down the substance, kept expectations honest the whole way through, and delivered something each group could point to as meeting their own bar. That range is rare.
