Stonewald is an operators-led venture studio.
We build, advise, accelerate, partner and invest in businesses and founders so they can reach their full potential.
WHY WE DO THIS
Ventures are how industries — and lives — actually change.
The world is full of interesting problems. The most effective way to solve them is to build companies around them. Problems spark opportunities. Opportunities become ventures. Ventures turn into work that matters — for founders, for customers, for the people around them.
We pull sharp minds into the same room and stay in it from the first assumption to the exit. Building makes us better backers, and backing makes us better builders — which is why we will not stop doing either. Expertise, empathy, embedded operators, and capital, from start to finish. Nothing is guaranteed. With us, it is more likely to take off.
WHY WE DO THIS
WHY WE DO THIS
From Founding to Funding,
and From Scaling to Exiting.
01
Build
Corporate partnerships | University partnerships | Validation | Problem–solution fit
Some ideas start with us. Others arrive through companies and universities that already feel the problem. We test the assumptions, prove the solution, shape the model, and take it to market.
02
Advice
Product–market fit | Founder-led sales | Team (re)building | (Re)launch
The entrepreneurial map is easy to get lost in. We bring a clear route, people who have walked it, and a network that opens doors. Strategy when you need a heading; operators when you need to move.
03
Accelerate
Fundraise | Network | Market expansion | Board | M&A
Growth has to be fast and still hold together. We help you expand — product, category, or geography — with data, introductions, and people who have scaled before. Swift, not sloppy.
04
Invest
B2B | SaaS | Consumer | Applied AI
We invest at pre-seed and Series A, usually alongside a trusted lead, in companies already finding a market. Capital plus a seat at the table — aimed at a real, profitable exit, not a vanity round.
Be the Founder of our next Venture.
WHY WE DO THIS
WHO WE ARE
Brains-on.
Hands-on too.
01
Brand & product
Designers who have built names people remember and products people actually use — not moodboards that die in a Figma file.
02
Marketing & go-to-market
Positioning, launch, and a ruthless view of the customer. Who buys, why they buy, and how we reach them before the budget disappears.
03
Integration & strategy
The brand has to live inside the product, and the plan has to survive contact with a real market — from formation through to a sale.
04
Finance, legal & talent
Numbers, cap tables, contracts, hiring, and early talent — the unsexy work that keeps a young company from tripping over itself.

The person in the Chair
Pierre
Guivarch
Two decades of building, running and backing companies in the UK and Ireland. I started Stonewald to stay inside innovation and growth — and to put more founders in a position to do the same. That is how we create those rare moments when a company actually happens.
WHY WE DO THIS
THE STUDIO IN NUMBERS
Small on purpose. Serious about the work.
We are not a campus of hundreds. We are a tight studio, a handful of core teams, and a network we actually use. That is the point: enough muscle to build, not so much theatre that nobody ships.
