How can AI do this for £79?
80% of advance assurance applications follow the same structure: qualifying trade, share classes, investment timeline, use of funds. Our AI handles these standard cases in minutes. That's why this costs £79, not £2,000.
For the 20% of cases that are genuinely complex — group structures, connected trades, knowledge-intensive company status — we'll tell you upfront and refer you to a specialist partner. No charge. No hard sell.
The same AI that handles standard cases also knows when to step aside.
Single company, straightforward qualifying trade, standard share structure. AI handles end-to-end.
Group structures, multiple share classes, connected parties, overseas subsidiaries.

What Every Founder & Investor Should Know
Before you pay anyone — us or an accountant — understand what advance assurance actually is and why it matters.
Investors expect it
Most angel investors and SEIS/EIS funds won't commit capital without advance assurance in place. It's not legally required, but in practice it's table stakes for raising investment.
It's not tax advice
Advance assurance is document preparation — telling HMRC about your company in the format they expect. This is what accountants charge £2,000+ for. We do the same preparation for £79.
HMRC takes 6–8 weeks
Once submitted, HMRC typically responds within 6 to 8 weeks. The bottleneck isn't the application — it's how long it takes to prepare one. We remove that bottleneck.
Most companies qualify
If you're a UK company, less than 3 years old (SEIS) or 7 years (EIS), with fewer than 25/250 employees, carrying on a qualifying trade — you almost certainly qualify.
