Sergei Mochtchenkov, CFA
About
A wartime CFO for the moments most advisors avoid.
I'm Sergei Mochtchenkov, a Canadian CFA charterholder and fractional CFO. I work with founders and CEOs of $5M–$50M businesses when the financial situation has become urgent — cash is tight, books are unreliable, investors are asking hard questions, and the team needs someone senior in the room.
Across 300+ engagements on Upwork and direct retainers, I've stabilized startups, SaaS companies, education businesses, and multi-entity groups through cash crises, fundraising rounds, and pre-bankruptcy turnarounds. The work is rarely glamorous. The outcomes are real.

How I work — and why founders trust it.
01
Control before strategy
You can't strategize your way out of a cash crisis. Visibility, control, and discipline come first — every time.
02
Numbers you can defend
Every model, every report, every projection holds up to investor and lender scrutiny. No fluff, no padded forecasts.
03
Senior, hands-on, calm
I work directly with the founder. No handoffs. No junior staff. No drama in the room when it matters most.
