Features
- Search by name, handle or topic. Searches run when you press Enter, because Cosign rate limits its search tools.
- Full profiles in the sidebar. Experience, cosigns, founders and people for a company, loaded as you move through results.
- Funding and investors. A company's rounds, its investors grouped by round with a round filter, and an investor's portfolio.
- Open roles. A company's open jobs, filterable by team, with an explicit Load More.
- Favorites. Star people and companies into two private Cosign lists, so they also show up in the Cosign web app.
- Inbox. Read your Cosign conversations and accept or archive connection requests, with a menu bar count of what needs you.
- Recent searches. Shown when a command opens, removable one at a time.
Requirements
Quick Start
- Open Raycast and search for "Search Companies"
- Sign in to Cosign when the window opens. Raycast keeps the token afterward.
- Type a company name and press Enter, then press ⌘K for its funding, investors and open roles.

Known Issues
- Investor firms can't be favorited. Cosign treats investing firms as organizations everywhere else (they have profiles, appear as investors, and have portfolios), but its companies list refuses them: adding one fails with "Investing firms are not eligible for this list." No other list kind (people, jobs, products) fits a firm, so the extension can't save one. This is a Cosign rule, not an extension bug.
- Topic search is capped at 300 results, 10 per request. The count shown ("20 of 300") is the cap on ranked results, not the number of companies that match. Each "Load 10 More" press spends one call from Cosign's semantic search budget (30 per minute, 200 per hour, 600 per day).
- Open Roles are matched by company name. Cosign's job search has no company filter, so the extension asks for roles at an employer by name. Two companies with the same name can share results.
- Avatars are missing in some submenus. Founders, People, Investors and Cosigned submenus don't show images yet.
- No Follow or Claim. Cosign's MCP has no tool to follow or claim a company, so the extension can't offer those actions.
- Messages can be read but not sent. Cosign's MCP has no tool to reply to or start a conversation, so "Reply on Cosign" and "Message on Cosign" open the thread (or the profile, when there is no thread yet) in the browser. "Message on Cosign" appears only for people who are on Cosign.
