Investor outreach
She researches investors, matches them to your thesis and drafts intros in your voice – then queues them for you. Nothing goes out until you approve it. That's what keeps it compliant, and what keeps it yours.

Fundraising documents
ASAs, SAFE notes, term sheets, board consents – Cecile prepares the drafts, auto-filled from your company and your round, ready for you and your adviser to complete.
And because she knows the SEIS and EIS rules, she flags anything that would break your relief – a discount that voids it, or a long-stop date that misses the window.

Beyond the raise
Cecile keeps the money moving – chasing overdue invoices, challenging the ones you shouldn't pay, matching receipts and keeping your books ready. The admin that used to eat your evenings, handled.
A co-founder who does the boring bits, too.

Not generic AI
Cecile is trained on the hard-won knowledge of operators with over 30 years in startups and SMEs. She doesn't guess at the rules – she learned them from people who have lived them, across every discipline a raise touches.
Who's behind it
Adviser, founder, and once an investor too – Seisly, and Cecile, are built from all three vantage points, not one.
A decade preparing, advising on and taking over applications.
The assurance engine reflects what actually passes.
Founded companies, and the UK's first SEIS fund, and raised the money himself.
The OS is shaped around where a founder's week really goes.
Launched and ran the UK's first SEIS fund – years on the side of the table that writes the cheques.
Outreach is built on what makes an investor actually reply.
