A boutique ledger practice for science-led founders.
Ortiz Ledgerworks was founded on a simple observation: the founders we admired most — the ones moving real science from bench to clinic — were drowning in the part of the business that should be quietest. Their books.
We built this practice to fix that. Headquartered in Massachusetts' Merrimack Valley — a short drive from Kendall Square and the densest concentration of biotech in the world — we work with founders across the country, all stages from pre-seed through Series B.

Specificity over generality
Generalist accountants apply generalist categories. We learned the science so the books reflect the work.
Quiet rigor
Closed books on the same date every month. No drama. Just the report, on time, in your inbox.
Founder fluency
We translate between you, your investors, and your future auditor — without losing your voice.
We'd rather show than tell.
Most engagements begin with a 30-minute diagnostic call. No commitment, just clarity.
