Founders moving fast. Enterprises moving at scale. Leadership teams making AI decisions with incomplete maps. We work with all three and we hold the same standard across every engagement.
0 wasted conversations per client engagement. A commitment we track.
Built by people who've been on both sides of a bad brief.
We've been the dev team inside agencies watching good ideas get watered down by process. We've been the technical partners brought in after months of strategy produced nothing shippable. We started Foundry 5 because we knew exactly what this should feel like and we'd never seen anyone offer it.
The model is deliberate: direct access to the people actually writing the code, AI embedded as core infrastructure rather than a billable add-on, and timelines built around the reality of your business not ours.
Whether you're a founder going from zero to your first product, an enterprise team integrating AI into production systems, or a leadership group that needs a clear-eyed view of where AI fits your next 18 months the standard doesn't change. Senior people. Honest thinking. Work that ships.
Decision-makers in the room
The people scoping your product have shipped products before. There's no account manager translating between you and the people doing the work. You talk to the builders.
Direct relationships only
No agencies. No subcontractors. No indirect chains of accountability. Whether you're a startup, an enterprise division, or an executive team seeking advisory one relationship, one team, fully responsible to you.
AI-native since before it was obvious
We've been integrating AI into product architecture since 2022. Not as a feature as a foundation. It shapes how we approach every build, every integration, and every advisory engagement.
Five things we believe
Not slogans. Not aspirational posters. Five working principles we actually follow on every project we take on.
Design is the product, not the wrapper
Most teams treat design as the last step before handoff. We treat it as the foundation everything else is built on. When design is right, development is faster, users trust it instantly, and the product speaks for itself.
Built to ship, built to last
A demo that looks good isn't a product. We write clean, scalable code from day one, because shortcuts taken in build one become blockers in build two. We'd rather do it right than do it twice.
Honesty over comfort
We push back when something would slow you down. We tell you when a scope is too big for four weeks before we start, not halfway through. Honest partners are rarer than good developers.
Founders, not clients
We don't have clients. We have founders we work with and build lasting relationships. The difference matters. Founders need honesty, speed, and a team who cares about the outcome, not the invoice.
You should always know what's happening
Weekly updates. Real numbers. Clear blockers. You shouldn't have to chase us for information about your own product.

Small enough to care. Experienced enough to ship.
Twelve people based in London. No layers of management between you and the people doing the work. Everyone who works on your project is senior in their specialism and has worked on live, production products before.
Three things most agencies do not do. We do all three.
These are not features. They are the structural reasons our clients come back and refer others.
We scope before we price.
Most agencies give you a quote based on a brief. We write a scope document first, covering exactly what gets built, what does not, and in what order, then price from that. You know what you are buying before you buy it. The scope is a contract you can hold us to.
You see work in week two. Not week six.
You get access to a working staging environment in week two of every build. Not a prototype. Not wireframes. The actual product in progress. You can click through it, test it, and give feedback before the build is finished. You are never waiting for a big reveal.
The same team builds and maintains.
We do not hand you off after the invoice. The team that built your product is the team you talk to when something breaks at 11pm six months after launch. No re-onboarding a new team. No explaining what was built. Same people, same context, same commitment.
The things that are non-negotiable for us.
These are not HR policies. They are the informal rules the team has built up by working together and watching what makes projects succeed and fail.
No work starts without a written scope
Not an email thread. Not a call summary. A proper document that both sides sign off. This protects you and it protects us.
Bad news travels fast here
If something goes wrong on a project, the client hears about it before we have fixed it. Not after. We do not hide blockers to look competent.
Security is not a checklist item
Every build goes through a security review before launch. Not because clients ask for it. Because it is the only responsible way to ship.
Documentation is part of the build
Code without documentation is a gift with no label. Every handover includes clear, readable docs a future developer can actually use.
We say no when we need to
If a feature request will hurt the product, we push back. If a timeline is not realistic, we say so. We are not yes-people. We are partners.
Time zones and overlap
Our London team operates in UK business hours. Client calls, standups, and updates all happen when you need them. Nothing falls through the gap.
Things founders ask before they reach out
If your question is not here, book a discovery call. Honest answers, no sales pitch.
Foundry 5 was founded in 2021 in London by engineers and product leads who had watched startups fail not because of bad ideas, but because the agencies they hired could not ship on time or on budget. The first two clients raised seed rounds within weeks of launch.
50+ products across fintech, healthtech, AI, edtech, construction tech, consumer apps, and Web3. The team has maintained a 100% on-time delivery rate across every project in 2024.
Written scope before any code is written. Daily updates during the build. A staging environment live in week two. 30 days of post-launch support included by default. A risk-free first project guarantee. And the same senior people who scope a project also build and maintain it - no handoffs to junior teams.
Yes. Many clients come to us with a direction but not a finished specification. We help define what to build and what to leave for later in a scoping session before any development begins. We push back on anything that would slow you down or burn budget unnecessarily.
Yes. We work with pre-seed founders, Series A scaling teams, and enterprise divisions integrating AI into production systems. We have delivered FCA-regulated fintech products, COPPA-compliant health apps, and AI systems for regulated industries.
Every first engagement with Foundry 5 comes with a full refund guarantee. If you are not satisfied with the outcome, we refund you in full. No conditions, no partial refunds. It applies to every new client on their first project.
We work with founders who are ready to move.
If you've got the idea and the urgency, we've got the team and the timeline.
