The person you bring in when it needs someone who’s done it before.
Twenty years of building, scaling and selling fintech businesses, now put to work on the projects that matter: launching products, entering new markets, moving upmarket, raising capital and tightening operations.
Hands-on leadership for the projects that matter, from David Nunn: employee #3 at Braintree Europe and founder of Rvvup, sold to Zopa.

“Drive, product vision, and a team that would follow him anywhere. I’d back him again tomorrow.”
“We backed David at Rvvup, and he delivered what you hope for as an investor: a high-quality product, a team to match, and relentless execution through a very tough fintech market. He made the right and sometimes hard calls to keep the business growing and thriving, all the way to a successful exit to Zopa Group PLC. Drive, product vision, and a team that would follow him anywhere. I’d back him again tomorrow.”
“Demanding, straight with you, loyal to his people. I can’t recommend him highly enough.”
“I was David’s CTO at Rvvup. He is the clearest founder I have built for: deep in the product and the market, quick to decide, and then he defends the space for the team to do the work. Through the toughest fintech market I have seen he kept us funded, focused and shipping, growing the business all the way to the exit to Zopa. Demanding, straight with you, loyal to his people. I can’t recommend him highly enough.”
“Few operators combine standards and drive the way he does.”
“David worked for me at Braintree, where he built our European business from nothing into a 40-person operation processing billions a year, winning many of the biggest brands and merchants in the market. He builds teams and processes that last, holds a genuinely high bar, and does it with a discipline, and a decency, that makes people want to work for him. Few operators combine standards and drive the way he does.”
“If you need something done, fast and to the highest standard possible, just call David.”
“I led worldwide sales at Braintree and promoted David from running Europe to running Europe and Asia-Pacific, building and scaling revenue teams across regions and cultures as he went. I’ve worked with a lot of revenue leaders; there’s no better team builder or executor out there. If you need something done, fast and to the highest standard possible, just call David.”
People call when something is stuck, or something big is about to start.
The round that has to land.
The story, the numbers, the deck and the process, run properly. I've raised from the funds you're pitching.
The cost base nobody wants to touch.
A line-by-line read of cost and runway from someone who ran a fintech lean through a downturn. What goes, what stays, in what order.
Enterprise wants you. Your website says otherwise.
The buyer, the messaging, the website and the sales motion, rebuilt for enterprise. I've sold to the biggest brands and know what their procurement teams check.
The thing that won't go live.
Product, site, go-live plumbing and first customers, unblocked in the right order by someone who ships production software today.
The board-level read.
A written, board-ready view of the plan, the team and the risks nobody has written down, from someone who has sat in every seat.
Opening the Gulf or South-East Asia.
Structure, first hires, first customers and the right introductions, from an operator with a DIFC-registered company and two decades across Europe and Asia-Pacific.
Something that doesn’t fit a job description.
Within one working day you’ll get a yes and a plan, or the name of someone better placed.
Tell me about itRead it. Fix it. Stay as long as it takes.
The Read
- Everything on the table: numbers, product, site, pipeline, people
- A written verdict: what's wrong, ranked and costed
- A readout call to argue with it
- A quote for the Project, or an honest "you don't need me"
The Project
- Named outcomes on the problems the Read put at the top
- I do the building, with one point of contact on your side
- Weekly written status, decisions made with you at every gate
- Handed over documented, so it keeps working when I go
The Seat
- Someone who already knows the business
- Monthly or quarterly cadence
- Available between meetings for the calls that can't wait
- Governed like a board role, not a consulting contract
Priced on the problem.
You pay for what getting it right is worth, not a day rate. A fixed price or a monthly retainer, agreed before work starts.
Built to hand over.
Everything I build is documented and handed over in full. If I stay, it’s for the next problem, not because you’re stuck.
Two at a time.
Special projects don’t survive being one of twelve. Two at once, no more, and a waiting list rather than a diluted job.
Real or cut.
Every claim here is real, or it was cut. Same standard in the work: no invented numbers, no guesses dressed as facts.
Twenty years of the same job, at different scales.
Building things people pay for, keeping them growing when the market turns, and selling them well. In the order it happened.
Rvvup / Zopa
Braintree / PayPal: employee #3, then General Manager of Europe & APAC
Joined before the product had a European customer. Built Europe from zero, then ran an 80-person operation across Europe and APAC processing billions a year, winning many of the largest brands and merchants in the market. Seven years of hypergrowth inside one of the most demanding commercial cultures in fintech, where "production-grade" and "commercially serious" were the entry requirements, not the goal.
Rvvup: founder and CEO Sold
Founded, raised $20m from HV Capital and Lakestar, and built one payments platform across three rails that had never sat together: card, bank and blockchain. Cards, mobile wallets, buy now pay later, open banking and crypto in a single integration, plus tools built for the B2B merchants online commerce had left behind, from payment links to ERP integrations. Acquired by Zopa Group in August 2025, with the earn-out completed on full terms in August 2026.
Rvvup Tech Ltd: incorporated in the DIFC
Set up to support Rvvup’s planned expansion into the UAE and Singapore. It stayed outside Zopa’s acquisition of the UK business, Rvvup Limited, and is now the company behind the projects on this page.
CFOVUE: built and operated solo Live
An AI FP&A product for pre-Series A SaaS founders, built and run end to end by one person: product, infrastructure, a live billing migration, paid acquisition and outbound. It's why the launch and go-to-market work above comes from someone who did it last month, not years ago.
Board and investor side
Active board member and angel investor in a Series C payments fintech, and adviser to other fintech and software companies. Has sat through the board meeting where the plan meets reality from every seat at the table: founder, executive, investor. The second-opinion work is written from all three.
Why him.
A real exit
Founded a payments fintech, raised $20m and sold it to a PLC in 2025, with the earn-out completed on full terms.
Deep corporate commercial
Employee #3 to General Manager of Europe & APAC at Braintree-PayPal. Knows what enterprise buyers and boards expect.
Current practitioner
Operates a live software business solo, on today's tools. Shipped, charged and diagnosed a funnel this month.
Exit, scale and current practice, in one operator.
Describe the problem.
One email: what's wrong, what it's costing you, and when it has to be fixed by. You'll have an answer within one working day. If it's a fit, that answer is a proposed Read with a fee and a start date. If it isn't, it's a straight no and, where I can, a better name.
