Post-proof of concept means the idea has been validated. Business validation is the process of proving that your business idea is viable; that there is a real demand, people are willing to pay for it.
You may be able to demonstrate validation through early customer engagement, funding received (either grant or private investment), you may have started to generate revenue. -

Most of the programme is delivered remotely and is designed to be flexible around the demands of building a business. However, there are a few key touchpoints that require dedicated time, including workshops, expert sessions, and the Boot Camp (compulsory, 10th–11th June 2026).
We ask that you commit a minimum of 4–6 hours per week to the accelerator programme. This includes time spent participating in scheduled sessions as well as working on your business each week.
