Human Interest, Inc. is a San Francisco based retirement benefits company that provides full service 401(k) and 403(b) plans to small and mid sized employers in the United States, along with individual retirement accounts. It handles plan administration, recordkeeping, investment lineups, compliance testing and payroll integration through software, which lets it serve employers too small for traditional retirement plan providers, and it says it works with more than 47,000 businesses. The company was founded in 2015 by Paul Sawaya and Roger Lee and originally traded as Captain401 before rebranding. It has raised venture capital repeatedly, including a 267 million dollar round in 2024 and a further raise in October 2025 that valued it at about 3 billion dollars.

The disclosed stakes

One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.

Where each figure comes from

A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.

What this page is not

It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of Human Interest, Inc. where a holder stated one, and are missing where no holder did.
