About Rubric Financial
An accounting firm built on experience and trust.
Rubric Financial brings partner-led, CPA-reviewed accounting and finance services to small businesses and individuals. The same partner every conversation. A licensed CPA on every filing. (Our sister practice for venture-backed startups operates as StartupCFO.AI.)
Our Approach
We believe accounting should give business owners clarity, not more spreadsheets. Every engagement is partner-led, Harry, Aparna, Nirmala, Nitasha, or Girija runs your relationship from day one, with a licensed CPA reviewing every filing, and priced transparently so you know what you're paying for.
Founded in 2025 and headquartered in San Francisco, we combine traditional accounting craft with modern tooling and software to deliver accurate, timely, and useful financial information. The result: clean books, clean filings, and a finance partner who actually understands your business.
What We Believe
Every business owner deserves a finance team that picks up the phone, returns email within one business day, and explains the numbers in plain English.
How We Work
Partner-led engagements with CPA review. Fixed monthly fees. Modern cloud-based stack. Proactive communication and accurate monthly close, every month.
Who We Serve
Small businesses and individuals, service businesses, professional practices, and high-net-worth individuals. Building a venture-scale startup? See StartupCFO.AI, our sister practice for venture-backed startups.
The People You'll Work With
Same partner every conversation. Not a rotating team.
Engagements are led directly by a partner. The same person on your kickoff call reviews your work, runs your close meeting, and picks up the phone in July.
