Slice of Lime Reviews
Makes you wonder why we tolerated the previous site's load times for as long as we did
Rodrigo Cardoso / VP of Technology | May 29, 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
How long it took us to launch a new tariff had become a genuine competitive disadvantage, and the product configuration layer was the obvious bottleneck to fix first.

Questions & Answers
Positive ROAS by the end of the very first full campaign cycle
Willem Jansen / Chief Technology Officer | May 17, 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
Our campaign workflow had sprawled across a dozen disconnected tools with constant manual reconciliation. It was slowing us down and introducing errors we couldn't afford.

Questions & Answers
Product teams can finally move independently instead of queuing behind each other
Agnieszka Zielińska / CTO | Apr 12, 2026I went into this engagement genuinely skeptical. A previous vendor had left us with a system that technically worked but that nobody trusted, and I wasn't interested in repeating that experience. This team earned trust the slow way — solid discovery documentation, technical proposals that held up under scrutiny, sprints that landed when promised, and ultimately a production system that has simply behaved. I don't open conversations about them with caveats anymore.
Project summary
Grid modernization funding required us to prove demand-response capability. The models existed on paper — we needed engineers to actually build and run them in production.

Questions & Answers
Changed how our engineers think about release risk, not just how fast they can ship
Ananya Raman / Director of Engineering | Apr 05, 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 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
Polish level on the app has generated unprompted compliments from our own customers
Alexis Faraday / Chief Digital Officer | Mar 17, 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
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.

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.

Headless setup finally let content and engineering ship independently of each other
Nicolas Fontaine / Directeur Technique | Jan 13, 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.
