How to sell to developers and engineers on X (the GTM channel nobody uses)

If you sell to CEOs, engineers or developers, you already know the hard part: they ignore cold email and they are picky about LinkedIn. The channel most founders overlook is the one where those exact people actually spend their time. It is X.

Why X is the underrated channel for a technical audience

Developers, engineers and the founders who hire them live on X. They post, they argue about tools, they follow each other. But almost nobody runs real outbound there, so the inbox is not burned the way email and LinkedIn are. That makes it the rare channel where a relevant, human message still gets read. The catch is that doing it by hand does not scale, and most tools do not touch X at all.

How to actually run it

1. Build a list of the right people on X. Not everyone, the specific developers and engineers who fit your product, pulled from who engages with the right posts and accounts.
2. Write messages that sound human, because they are. A technical audience spots a template instantly. Each first message should reference why that person is on your list.
3. Send from your own account, in a paced sequence. Your own handle, so every reply builds your relationship and stays yours.

This is exactly what the X channel in PumpGTM does: build lists of developers and engineers on X and run automated, human-written sequences from your own account, alongside LinkedIn and email. The X DM automation is covered in X DM automation for likers, repliers and followers, and it is one of the differentiators we lead with on the comparison pages. 25+ Y Combinator companies run it.

It works best as part of a multi-channel sequence

X on its own is good. X plus LinkedIn and email, reaching the same person across all three, is better, because any single channel misses people. That cross-channel method is the multi-channel outbound playbook, and the targeting that makes it work is in how to do GTM like an engineer. Start from your own product at pumpgtm.com.

Questions founders ask

Why sell to developers on X instead of email? Developers and engineers often ignore cold email and are wary of LinkedIn, but they are active on X every day. Because almost no one runs outbound there, a relevant human message still gets read.

How do you find the right developers on X? Build a list from the people who engage with the right posts and accounts in your space, then filter to the specific roles you sell to, rather than messaging everyone.

Can you automate X outreach without sounding like a bot? Yes, if the messages are human-written and reference why each person is on your list, and they send from your own account in a paced sequence. A technical audience spots a generic template instantly.

Should X replace LinkedIn and email? No. It works best reaching the same person across X, LinkedIn and email in one coordinated sequence, since each channel reaches people the others miss.
