About the data

Colorado Lobby Guide

The Colorado Lobby Guide is an independent directory of the lobbyists registered with the Colorado Secretary of State and the clients they represent. It takes the public registration record and makes it something you can actually use: searchable, readable, and up to date.

Every listing comes from the Colorado Secretary of State: lobbyist registrations and monthly disclosure reports. The guide currently lists 694 registered lobbyists and lobbying firms (127 of them firms) and 1,947 clients. The data was last refreshed on November 2, 2026.

We publish names, firms and organizations, the clients each lobbyist represents, city and state, the income lobbyists report, and the positions they report on bills. We never publish phone numbers, street addresses or personal email addresses.

Lobbyists can claim their listing for free to add a bio and areas of expertise. Claims are checked by hand against the official record before anything changes.

What you will find here:

• Every registered lobbyist and lobbying firm, A to Z, with the clients they represent.
• Every client that employs a registered lobbyist, and who lobbies for it.
• A link back to the official filing source on every profile.

To correct something, write to clerk@fiftydomes.com or claim the profile. Changes to an official filing must be made with the Colorado Secretary of State.
