Advisor · Seed & Series A · London
You don't need another framework. You need someone who's been in the seat.
I help Seed and Series A founders navigate the calls that keep them up at night, like is this working, should we pivot, what do I do about my co-founder, as an operator who's made those calls himself and talks to founders every week, not a coach reading from a script.
If your plan has stopped working, get in touch →I built and ran Rhino for six years with my own money on the line, so I understand the founder's seat from the inside, not from a playbook. I have made the calls I now help others make, from finding fit when it wasn't coming to walking away from a working business for a better one.
Most teams say they're experimenting; few are running experiments, with a hypothesis, a kill criterion, and a decision at the end. The difference is six months of runway. I help pre-PMF teams turn the search into a discipline.
At Rhino, that discipline, not a stroke of genius, is what found our fit in 2023.
Growth has flattened and everyone has a different theory why. The raise closed and the board expects a story you no longer quite believe. A pivot is on the table but the team is split. For that moment: a three-week reset sprint, outside-in diagnosis, two structured working sessions, and out the other side a written decision memo plus a 90-day plan with named owners.
A decision memo: what you're choosing, and what you're explicitly stopping.
The strategy is right but the machine is chaos: shipping is reactive, growth is a collection of hunches, and every priority call escalates to you. I help founders install the operating process, how product and growth decisions get made weekly without you in every room.
Our API squad was nearly all engineers, our PLG squad almost all growth. Structure, not more management, let the company run without me refereeing.
One strategic question that's bothering you, worked through fast. It ends with the decision logic in writing.
Outside-in diagnosis, a few working sessions with you and/or your leadership team, a decision memo and a 90-day plan. Not a deck.
Some founders keep me on to hold the plan honest. The longer we work together, the faster I am when something breaks.
Bulgarian-born, trained as a manufacturing engineer at Cambridge, I moved into early crypto in 2018 via Bitfinex and its trading-venue subsidiary Ethfinex. In 2019 I co-founded Rhino.fi (originally DeversiFi) with Will Harborne and Ross Middleton to make DeFi safe and easy to use.
Over the next six years we grew it from three people to a 35-person company serving 2M+ users, raised funding led by ParaFi Ventures alongside Lightspeed, Faction, OKX and Bitfinex Ventures, and built the business to $10M+ EBITDA. We pivoted twice: in 2023, experimenting our way from the original product to real product-market fit; then in 2024, after I took over as CEO during the peak year, out of B2C retail flows into B2B stablecoin infrastructure, ahead of the industry, with B2B revenue overtaking B2C within months.
Today Rhino is a top-10 crypto bridge by volume, now led by my co-founder Will. I stepped down as CEO and exited my stake through a private secondary sale in late 2025. Along the way I've angel-invested in seven early-stage companies, and these days I work with founders on the problems I know from the inside: finding fit, changing course, and building the machine that ships.
Capturing travels on film. Two wheels when I can. Two skis when I'm lucky.
Thirty minutes, no pitch. For Seed and Series A founders. First conversation costs nothing.
