About Altiva Finance

Built by Operators, for Operators

We have sat in your seat. Our team of finance leaders, Big 4 alumni, and startup veterans built Altiva Finance to be the partner we wished we had.

Our Story

Founded at the intersection of operator experience and financial expertise

Altiva Finance was born from a simple observation: startups deserve world-class financial leadership, not just bookkeeping. Our founders came from Big 4 accounting firms and VC-backed startups, and they saw the gap firsthand.

Too many startups were choosing between expensive full-time hires they could not yet afford and junior freelancers who could not deliver strategic insight. We built Altiva Finance to bridge that gap.

Today, we are a team of seasoned CPAs, fractional CFOs, and finance professionals who have collectively helped hundreds of companies navigate fundraising, scaling, and building for the long term.

“Our mission is to give every ambitious startup access to the financial leadership that was once reserved for Fortune 500 companies.”

— Alexandra Rivera, CEO & Founder
