CPA · Outsourced CFO

Tatiana Tamir

Financial leadership that turns numbers into decisions.

Strategic finance for founders who need a CFO in the room — not another report.

Let's talk

Who I work with

I work with Israeli entrepreneurs from pre-seed through Series A who are building for the American market — founders who have outgrown bookkeeping and need a financial partner who can sit at the leadership table, face investors, and build the foundation for growth.

The professional story

From the Big Four to the boardroom.

I started at PwC. As an audit manager at PwC Israel — and later specializing in international companies at PwC New York — I sat across from public companies, Nasdaq-listed entities, and private growth businesses. I learned how the best teams turn financial rigor into confidence.

I then moved inside. As a controller for a public company, I prepared consolidated statements under IFRS, led month-end, and saw what it means when finance actually drives decisions — not just documents them.

Today I work as an outsourced CFO. I saw the gap between accountants who count and leaders who build decisions — and I decided to close it. My goal is simple: to be the CFO you actually want by your side.

What's different

Built for depth, not volume.

Less clients, more depth

A deliberately small portfolio so I know your cash, your board, and your next raise — not just your filings.

Permanent retainer, not hours

Ongoing partnership on a clear retainer. You get continuity and ownership, not a timesheet.

I'm in the chair

You work with me — not a rotating junior team. Senior judgment on every material conversation.

Decisions, not just reports

Budgets, forecasts, and board packs designed to help you act — with the clarity to move fast.

How we work

Social proof

What colleagues and clients say.

I had the privilege of working alongside Tania for several years. She is one of the most diligent CPAs I've met — professional, pleasant, and consistently praised by her clients. Kind, goal-oriented, and precise. I wish every self-employed professional a CPA like her.

Tatiana is a dedicated and caring CPA. She helped us deeply understand our company reports and saved us over ₪50,000 that had been misclassified by bookkeeping. I recommend her wholeheartedly.
