Special Projects

When you need 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.

“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.”

“Straightforward in the deal, and true to his word after it.”

“We acquired Rvvup in 2025 because David had built a strong product and team that were very complementary to our product strategy. What stood out was how he handled everything after the deal: he stayed close, handed over properly and delivered what he had committed to, in full, while helping his team settle into a much larger organisation. Straightforward in the deal, and true to his word after it.”

“Few operators combine standards and drive the way he does.”

“David worked for me at Braintree, where he built our European business from nothing to 40 markets, processing billions a year and winning many of the biggest brands and merchants in Europe. 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, 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, call David.”

“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.”

“Hands-on, rigorous on the numbers, and generous with what he knows.”

“After we acquired Rvvup, David got involved right across our business, working closely with the key teams. He made sure Rvvup beat its volume target, supported the integration into Zopa, and worked side by side with my commercial team to build a high-performing sales organisation, with effective sales targets and the compensation and career frameworks to back them. Hands-on, rigorous on the numbers, and generous with what he knows.”

“The vision and speed of a founder with the discipline of a business leader.”

“Working with David at Rvvup, I saw a founder who understood both the commercial opportunity and the financial discipline needed to pursue it. He welcomes challenge, makes difficult decisions and follows through. The vision and speed of a founder with the discipline of a business leader.”

The situations

What needs to move forward?

Raise funding

A clearer investor story, stronger pitch materials and numbers you can defend.

Reduce costs

Find what to cut, protect what matters and make your cash last longer.

Win bigger customers

Sharpen your website, sales story and approach for enterprise buyers.

Launch your product

Make the value clear and give your team a plan to reach the right customers.

Get a second opinion

An experienced view of your plan, your risks and what to tackle first.

Enter a new market

A practical route into the Gulf or South-East Asia, with the right introductions.

Tell me what’s getting in the way. I’ll come back within one working day.

Let’s talk
How it works

Read it. Fix it. Hand it over.

  1. Pressure

    Revenue isn’t where it needs to be. Costs haven’t waited.

  2. Diagnosis

    What needs to change?

  3. Action

    A clearer offer. A stronger sales story. A tighter operating plan.

  4. Resolution

    Clear decisions. Work delivered.

A short looping film. Revenue falls short while costs keep rising, and the picture turns red. Pipeline, positioning and operating costs are diagnosed. Then the work arrives one piece at a time: a more compelling site, a sales story with proof, and an operating plan with milestones. Each is ticked off, and the picture turns green as revenue climbs clear of costs.

Step oneAlways first

The Read

Ten working days · fixed fee, agreed up front
  • 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"
See an example Read →
Step twoWhere the work happens

The Project

Fixed-price project, or monthly retainer
  • 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
Step threeOnly when asked

The Seat

Ongoing · board or advisory
  • 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
Rule 01

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.

Rule 02

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.

Rule 03

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.

Rule 04

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.

Braintree / PayPal: employee #3, then General Manager of Europe & APAC

Joined before the product had a European customer. Built Europe from zero, then ran Europe and APAC, processing billions a year and 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 "enterprise-ready" 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.

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.

Ground rules: no outcome guarantees, ever: nobody who promises a result can keep the promise · every claim here is real, or it was cut · you see what didn't work too, because avoiding it is half the value · built to hand over, never to trap.
