I'm passionate about empowering founders to have the opportunity to
build a business that could change their lives.

I’ve helped hundreds of first-time founders turn early ideas into validated, fundable businesses.

But of course, I didn’t start here.

I was very lucky. I grew up watching my dad build a small publishing company. That early exposure showed me something powerful: starting a business was possible - and it showed me that it was something I could do too.

In my early 20s, I started Deeson, a digital agency and spent over a decade growing it. We scaled to a 35+ person team, delivering complex digital platforms for clients like Johnson & Johnson, the Royal Household and ITV - generating millions in revenue, all without outside funding. After years of building and leading the business, I successfully exited the agency to TPXImpact plc.

That experience evolved into my next venture: OpenDialog, a conversational AI platform I co-founded with Ronald Ashri. What started as a series of Lean Startup experiments became a standalone company - and it grew into a venture-backed business with enterprise clients in financial services and healthcare.

Over the last five years, I’ve:

  • Coached 700+ founders through early-stage validation and funding

  • Angel invested in early stage startups

  • Taught Lean Startup skills across leading UK founder communities

  • Advised ambitious startups and mission-led founders

Now, I help founders:

  • Validate before they spend

  • Fund exactly what they need

  • Grow deliberately, with control and confidence
