Understand funding options: Start Up Loans versus SEIS equity
The British Business Bank provides government-backed Start Up Loans of up to £25,000 per founder at a fixed interest rate, ideal for early prototyping without sacrificing company equity. Alternatively, securing SEIS advance assurance gives early angel investors up to 50% income tax relief, making your venture significantly more attractive.
Run a structured cofounder trial sprint before signing agreements
Technical cofounders want to see real customer traction and respect for engineering complexity. Before discussing equity percentages, collaborate on a one-week trial sprint to solve a single customer problem. This confirms your communication style, work ethic, and ability to make joint decisions under pressure.
Scenario: Testing an automated clinic appointment portal in London
A commercial founder and a full-stack engineer collaborate on a self-service booking prototype for independent dental clinics. (Illustrative practical scenario, not a customer result.)
- Document the specific receptionist bottlenecks and patient cancellation rates that cost clinics revenue.
- Ship a minimal appointment prototype and test it with two clinic managers over a 7-day trial window.
- Review sprint velocity, user feedback, and founder compatibility before finalizing an SEIS-ready shareholders' agreement.
