meets founder access.

What founders and investors say.
Curated from LinkedIn recommendations and direct testimonials. Google Business reviews coming soon.
"Elena turned a confused early-stage fundraise into a clean, HMRC-approved structure in under three weeks. She thinks like an investor and operates like a CFO."
"Rare combination: a CFO who actually understands climate science, founder economics, and the SEIS/EIS rulebook. We brought her in for one engagement and never let her go."
"Elena's diligence on our use-of-funds and risk-to-capital narrative was the single biggest factor in closing our round."
Recommendations on LinkedIn carry the most weight. Google Business reviews are welcome too.
Where to find us.
Panels, masterclasses, and meet-in-person sessions. Updated by Elena directly — see the full calendar below.
