Why Attend SEIS and EIS Conferences in 2025?

Attending SEIS investor conferences does more than tick a box. It’s about:

  • Insider intel on upcoming SEIS/EIS rule tweaks and tax relief thresholds.
  • Direct access to founders gearing up for seed rounds.
  • Peer insights from seasoned angels who’ve navigated multiple exits.

Most events go beyond panel talks. You’ll find curated one-to-one clinics, hands-on workshops and informal side events that can result in genuine partnerships. If you’re serious about tax-efficient investing, missing these gatherings means missing deals—and the strategic know-how to structure them correctly.

The Power of Networking at SEIS Investor Conferences

Think about it: hundreds of likeminded investors in one room. You don’t just hear startup pitches—you forge connections with fellow SEIS champions. That’s how you build syndicates, share due diligence templates, and spot emerging trends before they hit tech blogs.

Tax-Efficient Insight from Industry Leaders

Conference sessions on SEIS/EIS often feature chartered accountants, HMRC advisors, and founders who’ve navigated the schemes successfully. These experts break down:

  • Qualifying conditions for SEIS/EIS relief.
  • Claiming CGT exemption on successful exits.
  • Avoiding common pitfalls that disqualify investments.

By the end of a day’s talks, you’ll have actionable strategies to structure follow-up deals and mitigate risks—without wading through dry HMRC guidance.
