Bogdan Stepanov, Founder, ControlFi

Bogdan has spent over nine years in M&A, investing and private markets — advising on 30+ cross-border transactions and private financings worth $700M+ across EMEA, North America and APAC, and managing a $500M+ private markets portfolio.

He has built and reviewed 100+ financial models across AI, FinTech, e-commerce and software, and founded ControlFi in 2026 to bring that work to founders who need investor-grade financials without a full-time CFO.

Why the background matters

Most financial models are built by people who have never had one attacked in diligence. Bogdan has been on both sides of that conversation — preparing the numbers for a sell-side process, and sitting on the investment side deciding whether to believe someone else's.

That is the difference between a model that produces a number and one that survives the question behind it.

What he works on

Fractional and outsourced CFO engagements for founders and established companies, financial modeling built on drivers rather than assumptions, and business valuations where the method and the sensitivities are shown rather than asserted.

Writing

He writes the ControlFi Library: practical guides on the numbers founders get asked about, each one built from work actually done rather than summarized from elsewhere.
