What it does

The ops layer between your spreadsheets and an administrator.

Rules, codified

Your LPA and side letters become constraints enforced on every entry they touch — not notes in someone's head.

Every figure, twice

Two independent engines compute each allocation and fee. A one-cent mismatch blocks the workflow.

A close that gates

Thirteen checks run before a period locks. A failure names the figure and the gap, not just that something is wrong.

Answers with receipts

Ask the fund a question; every number in the answer cites its ledger entry and derivation.

Tax and K-1s hand off to your preparer with a tied trial balance. Banking stays with your bank — wires are matched, not moved.

The trace

Click any number.

Every figure opens to its derivation — the formula, both engine runs, the ledger postings, the clause it came from.

AI reads and drafts. Engines compute. A person confirms. No model touches the math.

Design partners

A mutual selection, not a signup.

You: An independent venture firm running Fund I–III at $30–250M — side letters with real terms, an SPV or co-invest, a close with stragglers, an exit that wasn't cash.
Us: Full fund operations, free during the program. A direct line to the founder and real say in what gets built.
The ask: Your documents and history, an hour or two a month, and a call when something breaks.

First step: we migrate one fund's books and walk through it live — before you commit to anything. A call within a week; a decision either way.
