## Your next customers are in the conversation.

PumpGTM helps you find relevant buyers and start conversations from your own X, LinkedIn and email accounts.

[Find buyers ↗](/#find-buyers)

## How the rankings work

### A growing index of devtools companies

This is a researched starting set, not a complete census of every funded company. We focus on independent devtools, developer infrastructure and software-building platforms. Each company has a verified X account with more than 500 followers. Seed, pre-Series A and acquired companies are excluded.

### Company and founder audiences, ranked separately

Rankings use follower counts only. Views, impressions and engagement do not affect rank. Founders compete within their company’s funding stage, using their own account’s followers. The 500-follower minimum applies only to companies. Equal counts share a rank; filtering preserves the original stage rank.

### Funding stages you can check

Stages reflect the latest named rounds we could confirm through company or investor announcements, or direct reporting with company leadership. Research was checked October 3–4, 2026. An unlabelled extension or secondary sale does not automatically advance a stage. Open any company’s sources for the announcement, date and research notes. Founder coverage is expanding and includes founders who have since left.

### Snapshots, with the receipts

Follower counts are public X profile snapshots retrieved through [FxTwitter](https://github.com/FixTweet/FxTwitter). Each account has its own retrieval timestamp and source in the downloads. Counts can change and are not refreshed live. Unverified founder accounts stay unranked.
