How this directory is built
Each firm is matched to its SEC Form ADV registration by name and location, then verified against its CRD number — including advisers that register under a subsidiary entity (KKR via KKR Credit Advisors, Blackstone via Blackstone ISG-I Advisors). Regulatory AUM and private-fund activity come straight from the filing. See the methodology for how Altss sources and verifies data, and the glossary for terms like Form ADV, CRD, and regulatory AUM.

What is a registered investment adviser (RIA)?
An RIA is a firm registered with the U.S. Securities and Exchange Commission (or a state regulator) to advise clients on securities for compensation. Registration is recorded on SEC Form ADV under a unique CRD number.
How does Altss decide a firm is an RIA?
Altss matches each firm in its database to a Form ADV filing by normalized name and location, confirmed by CRD. Large managers often register under a subsidiary name, so the match accounts for those entity relationships rather than relying on the brand name alone.
Can I see all registered investment advisers?
This public directory lists the 100 largest by regulatory AUM. The full register — searchable by CRD, AUM, state, and private-fund activity — is available with an Altss account.
