How I work

Khaled Souf is co-founder and CTO of Togethrust, an ACPR-supervised French fintech, and runs a capped advisory practice alongside it. The practice is held to 10 to 15 hours a week, one company at a time, with one 360° Tech Audit slot per quarter.

No rates on this page. Every engagement is fixed-scope and fixed-fee, quoted in writing after a 30-minute diagnostic call.

Three ways an engagement runs

Whatever the shape, the scope is written down before it starts.

Flagship

Audit & technical due diligence

Reality Check, 90 min → Audit, 15 h → DD memo

A 90-minute Reality Check to establish whether an audit is warranted, then the 15-hour 360° Tech Audit, and where investors are involved, a due-diligence memo written to be forwarded without translation. Compliance is read through an ACPR lens.

By the session

Advisory

From first call to close

Diagnostic call

A free 30-minute call. If nothing here fits your situation, I will say so.

Written proposal

Fixed scope and a fixed fee, in writing, within 48 hours of the call.

The work

Remote by default, on CET. On-site in Paris, Geneva or London on request.

Close

Delivered, walked through, and closed. Nothing rolls on by default.

Ongoing advisory by invitation, for past audit clients.

Terms, plainly

How is an audit priced?

Fixed scope and a fixed fee, quoted in writing after a 30-minute diagnostic call; the rate card is sent then rather than published here.

Do you take fractional CTO retainers?

No. Togethrust is my full-time work and the practice is held to 10 to 15 hours a week, so advisory is booked one session at a time.

Do you work with non-fintech companies?

Yes. The five audit areas apply to any software company, and the track record covers mobility, medical distribution, healthtech and retail.

Do you accept equity?

Only on top of cash, never instead of it.

Tell me what you are trying to decide

A 30-minute call, then a written proposal with fixed scope and a fixed fee within 48 hours.
