Stakk

⭐⭐⭐⭐⭐ **5/5 — A team that genuinely cares about the outcome, not just the invoice** We run a membership organisation with around eight thousand members across the UK and we'd been relying on a clunky third party platform for years to manage communications and member engagement. It was functional but barely, and the complaints from our membership base had reached a point where doing nothing was no longer an option. We needed something bespoke and we needed it to actually work. Finding the right development partner felt like a daunting task. We're not a commercial business with a slick procurement process and we had real concerns about whether an agency would take a project like ours seriously or treat it as a lower priority alongside shinier clients with bigger budgets. Those concerns turned out to be completely unfounded with Stakk. From day one they treated us as they would any other client. The time they invested in understanding our organisation, our members, and the specific problems we were trying to solve was considerable and never felt rushed. They came to early meetings with ideas already forming, which gave us confidence that they were genuinely engaged rather than simply going through the motions. The development phase had its complexities, particularly around integrating with our existing membership database, and there were moments where the technical challenges were significant. What impressed us was how calmly and methodically those challenges were worked through. Nothing was ever presented to us as a crisis even when the problem underneath was genuinely knotty. We launched four months ago and member engagement has improved noticeably. More importantly the complaints have stopped. For a membership organisation that might be the most meaningful metric of all and Stakk delivered it.

⭐⭐⭐⭐⭐ **5/5 — Refreshingly straightforward in an industry full of smoke and mirrors** I'll preface this by saying I am not a technical person. I'm a business owner with an idea and a budget, and historically that combination has made me easy prey for agencies who talk a good game and then quietly underdeliver once the contract is signed. I've been there before and it's an expensive lesson to learn. With Stakk it was different from the outset. There was no jargon designed to make me feel out of my depth, no upselling of features I didn't need, and no sense that I was being managed rather than listened to. When I asked questions they answered them plainly. When I suggested something that wasn't the right approach they told me so, explained why, and offered a better solution. That kind of straightforwardness is exactly what you need when you're putting a significant amount of money into something you can't fully evaluate yourself. The process was well run throughout. I always knew what was happening, what was coming next, and what was expected of me at each stage. The design work was presented clearly with options and rationale rather than just a single direction and an expectation that I'd approve it. Small thing perhaps, but it made me feel like a genuine participant in the project rather than a spectator. The app itself exceeded what I had pictured when we first started conversations. It looks professional, it behaves exactly as it should, and my customers have taken to it without any of the friction I was half expecting during those first few weeks post launch. Eighteen months ago I had an idea. Now I have a product. Stakk deserve a great deal of the credit for that.

We're a two-year-old fintech startup and when we decided to build our mobile app we knew we couldn't afford to get it wrong. Budget was tight, the timeline was tight, and the product had to be good enough to put in front of investors. The pressure going into the process was considerable. We shortlisted three agencies and Stakk stood out during the pitch not because they were the flashiest but because they were the most prepared. They'd clearly looked at our business before the call, they referenced our competitors without being prompted, and they asked questions that showed they understood the market we were operating in. That level of preparation before we'd even signed anything told us a lot about how they'd approach the work itself. They were right on all counts. The project was managed impeccably throughout. The developer we worked with most closely was exceptional and became a genuine extension of our team over the months we worked together. Progress never stalled, problems were surfaced early rather than buried, and there was a refreshing absence of the vague status updates you sometimes get from agencies who aren't quite on top of things. The app launched on time and performed exactly as we needed it to. Our seed round closed two months after launch and more than one investor commented positively on the product quality during due diligence. That is probably the most meaningful endorsement I can offer. We have since recommended Stakk to two other founders in our network and both have had similarly positive experiences. Sometimes a recommendation comes with caveats. This one does not.

I run a small healthcare startup and building our app was, frankly, one of the most daunting things we've taken on as a business. The technical complexity, the compliance considerations, the sheer number of moving parts — it felt overwhelming before we'd even written a line of code. A friend in the industry pointed us towards Stakk and, looking back, that recommendation changed the trajectory of the whole company. What struck me first was how seriously they took the brief. They didn't just nod along and disappear to build something in isolation — they challenged us constructively, pushed back where our thinking wasn't quite right, and brought ideas to the table that we hadn't considered. It felt genuinely collaborative rather than transactional. The team they assigned to us were clearly senior people who knew their craft. No sense at any point that we were being handed off to someone junior or that corners were being cut to hit a deadline. And they did hit every deadline, which for a project of this complexity was no small feat. From a technical standpoint the app is rock solid. We've had remarkably few issues post-launch, and the ones that did crop up were dealt with quickly and without any drama. They'd clearly done the groundwork properly during testing rather than leaving us to find the problems ourselves in production. Twelve months on we're still working with them on new features. That probably says more than any review could. If you're in a regulated industry and worried about whether an agency can handle the nuance — they can.
