RIA Registration Delta Monitor — SEC Investment Adviser Leads & AUM Changes

Month-over-month RIA registration intelligence built from the SEC's official monthly Information About Registered Investment Advisers and Exempt Reporting Advisers compilation (Form ADV Part 1A data). Instead of a flat 15,000-row dump, this actor emits actionable lead sheets:

• new_registration — firms newly SEC-registered this month (brand-new RIAs to pitch)
• terminated — firms that dropped off the SEC register (breakaway/wind-down signals)
• aum_change — firms whose regulatory AUM moved more than your threshold (growth or outflow alerts)
• state_relocation — firms whose main office moved states (re-domestication, M&A, expansion)
• era_to_ria_graduation — Exempt Reporting Advisers that graduated to full SEC registration (fast-growing funds crossing the AUM bar)

Who it's for

• Advisor recruiters — every new_registration is a firm that just needs staff, tech, and custody.
• Custodian RIA-channel sales (Schwab, Fidelity, etc.) — catch breakaways and graduations the month they appear.
• Wealthtech GTM teams — target firms by state and AUM band the moment they register.
• Compliance consultants — new registrants need compliance programs; terminations flag churn in your book.

Modes

• roster (default) — a bounded slice of the latest monthly roster (filter by state / minimum AUM). Needs no history, always returns rows, and is the safe first run.
• delta — compares the latest month against the prior month. The prior snapshot is cached in the actor's key-value store, so a monthly schedule downloads each file only once. If no snapshot exists yet, the actor downloads the previous month's file directly; if neither is available, the first run seeds the baseline and exits cleanly with zero results (you are not charged for results).

Example input

  "eventTypes": ["new_registration", "era_to_ria_graduation"],
  "state": "TX",

}

Quick roster preview (default): { "mode": "roster", "state": "", "minAum": 0, "maxResults": 200 }

Use as an MCP tool

This actor works as a tool for AI agents (Claude, Cursor, etc.) via mcp.apify.com — ask your agent for "new SEC-registered RIAs in Texas over $100M AUM this month" and it can call this actor directly and read the typed dataset fields.

Honest notes

• Monthly cadence. The SEC posts one compilation per month (usually early in the month). Running more often than monthly re-reads the same file; schedule this actor monthly for clean deltas.
• Filename drift is handled. The SEC's monthly zip names drift (ia07012026.zip, ia060126_0.zip, ia050126.zip…). The actor tries all known name patterns and falls back one month automatically if the current month is not posted yet.
• SEC fair-access policy. All requests send a declared User-Agent per SEC guidance, and the actor downloads at most four small files per run.
• First delta run seeds the baseline (zero results, zero result charges). Every following monthly run emits real deltas.

FAQ

How do I get a list of newly registered investment advisers? Run with mode: "delta" and eventTypes: ["new_registration"] on a monthly schedule.

Can I track RIA AUM changes month over month? Yes — eventTypes: ["aum_change"] with aumChangePctThreshold (default 10%).

Does it cover Exempt Reporting Advisers (ERAs)? The ERA file is downloaded alongside the RIA file to detect era_to_ria_graduation events and to avoid mislabeling RIA→ERA moves as terminations.

Which SEC data is this based on? The SEC's monthly Investment Adviser compilations of Form ADV Part 1A filings (registered + exempt) — zipped CSV roster files published on sec.gov. No scraping of IAPD, no login, no API key.

Why did my first delta run return nothing? It seeded the baseline snapshot. The next monthly run emits deltas.

Pricing

Pay per result: you are billed only for the roster rows or delta events actually emitted (cap with maxResults). The full monthly SEC file is parsed regardless — you are never billed for rows filtered out. Baseline-seeding runs emit nothing and cost only the actor start.
