AI is one of the most active sectors for seed-stage fundraising in the UK, and most AI companies qualify for SEIS without difficulty. But there are specific areas where the eligibility rules create complications — and understanding them before investing saves problems later.
The general position: most AI companies qualify
SEIS does not have sector-specific rules for AI. Whether an AI company qualifies depends on the same tests that apply to every company: size (fewer than 25 employees, assets under £350,000 before investment), age (less than three years from first commercial sale), trade type, and total SEIS raised (under £250,000 lifetime).
Most AI application companies — tools for professionals, vertical AI products for specific industries, AI-enabled SaaS — qualify without difficulty. The AI element of the product does not create any specific eligibility issue.
Where problems can arise
Financial services AI
Companies providing AI products to regulated financial services firms — credit scoring models, trading algorithms, automated financial advice tools — need careful analysis. If the company itself is providing regulated financial services (not just software tools), it may fall into an excluded trade. If it is providing software tools to regulated firms without itself being regulated, it generally qualifies.
AI infrastructure
AI infrastructure businesses — GPU cloud providers, model training services — generally qualify for SEIS provided they meet the size criteria. The trade must be commercial rather than investment-oriented.
AI plus property
AI companies that have a property element — property valuation tools, AI for real estate — need to ensure the property activity does not constitute property development or dealing, which are excluded trades.
HMRC Advance Assurance for AI companies
For AI companies with complex business models or any doubt about trade classification, HMRC Advance Assurance is strongly recommended before fundraising. The application process requires submission of a business plan and trade description — HMRC will confirm whether the proposed raise qualifies and can flag any concerns before the investment is made.
