Without FCA restrictions on advisory, Oriel IPO doesn’t push products. It simply fosters connections, empowers you with SEIS/EIS know-how, and removes the cost barriers that often deter founders from pitching to top-tier backers. Let’s dive into the curated list of 55 UK SEIS/EIS investors trusted by SaaS startups in 2025.
