Raising capital just became a lot easier.

Let Caldwell Penn simplify the process and make you investment-ready.

Funding is tough. But it doesn’t have to be.

Most investors won’t commit unless your company qualifies for tax-efficient schemes like EIS or SEIS.

You might be:

  • Launching or growing a business and need early capital

  • Unsure how to navigate HMRC compliance

  • Worried about missing out on investor interest due to paperwork

  • Not confident in structuring your investment offer correctly

We handle the detail so you can secure the deal.

"EIS and SEIS are powerful tools for raising capital. We help you unlock their full potential and stay compliant."
Lawrence Evans
Partner and Managing Director
