What we look for

Is your business a fit?

We look for founder-led vertical software businesses: specialist products that customers rely on to run their organisations. Our focus is on the six sectors above.

  • UK-based B2B software
  • Founder-led or bootstrapped
  • Recurring revenue
  • Loyal, long-standing customers

For founders

Selling your software business.

A sale is about more than a change of ownership. It is also about what comes next for you, your customers and the people who built the business with you.

Stay on to lead, step back gradually, or hand over. We plan your role with you, so the transition reflects what you want to do next.
