Clean, source-tracked attorney & firm data

Attorney and firm data with every field traced back to a source.

Attorneys & law firms

It's your information. Make sure it's right.

We likely already have a record for you, built from public bar data. The tools other firms and companies use pull from data like this — so when it's wrong, it's wrong everywhere. Review what we show, correct anything out of date, or ask us to add you. It takes a minute and it's free — we never charge attorneys or firms, and never sell premium listings.

You're an attorney

Review and correct your record

Sign in with your work email — no password, no account. We match it to your bar record and show you exactly what we have; fix anything that's wrong and your correction becomes the authoritative value.

You're at a law firm

Keep your firm's profile accurate

Check your firm's roster, entity status, website, and contact details. Most firm data flows up from your attorneys' records — the fastest fix is to have them verify theirs.

For legal-tech teams

Why teams build on lawfirm.dev.

For the vendors, banks, and compliance teams that need lawyer data they can stand behind — here's the reasoning, in order.

1 · What sets us apart

Per-field provenance, in every response.

ZoomInfo and Apollo return flat records. We return the same fields plus a _meta.field_sources map — for every value, exactly which source produced it, when, and how confident we are.

Your sales team gets the lawyer's phone number. Your compliance team gets an audit trail proving you didn't source it from a defunct directory.

2 · How the data holds up

Source-tracked

Every field carries its provenance

No mystery columns. Each attorney record exposes per-field source, URL, confidence, and the date we last verified. Pass SOC2 audits without scrambling.

Bar-verified

We own the bar pipeline

Direct state-bar scrapes + the Florida Bar's official 127K-row member roster. Status, bar number, and admission date pulled from the authoritative source, not re-syndicated.

Agent-native

MCP server in the Anthropic registry

Narrow, well-named tools — lookup_attorney, verify_bar_status, find_attorneys_at_firm. Install once; every Claude agent gets clean lawyer data.

3 · Coverage

Florida now; more states on request.

The wedge: Florida, the largest single legal market in the Southeast. Other states roll out as bulk-export requests land with each state bar.

4 · Where it fits

Replace what your team spends on ZoomInfo for the lawyer slice.

Cleaner data than a general-purpose B2B firmographics provider, at a fraction of the cost. Bar status is current monthly. Firm entity status comes from the Secretary of State — not a website scrape that's six months stale. When an attorney submits a correction, every subscriber gets the update via webhook within seconds.

  • Per-field provenance on every record
  • Bar status verified against state directories monthly
  • Firm entity status from official state SOS data
  • Attorney-submitted corrections flow to every subscriber
  • Free MCP server — ship to AI assistants in 30 seconds
