How to market a B2B SaaS product on X as a technical founder
X works for technical SaaS founders because the audience is already there and the barrier is replies rather than followers — a good reply on a large account reaches more of your buyer than a post to your own 40 followers. The prerequisite is a bio that states what you build and for whom, because every reply that lands sends people there and a vague bio wastes the visit. Expect a slow first month: the compounding only starts once a handful of people in your niche recognise the name.
The play for X
- Format
- Build-in-public thread + reply to bigger accounts in your niche
- Cadence
- Daily for 2 weeks, then 4x per week
- Prerequisite
- A bio that says what you build and for whom
This is the same play Beacon uses when it builds a channel plan — not a summary written for this page.
When this is the wrong channel
X is the wrong channel if your buyer is a non-technical operations or finance team, and a poor fit if you cannot tolerate posting into silence for several weeks before anything moves.
How to start on X
In order. Each step is doable this week.
- 01
Rewrite the bio first
This is the prerequisite. It needs to say what you build and who it is for, in words your buyer uses. Everything else on this channel drives traffic to it, so a vague bio quietly discards the work.
- 02
Pick 20 accounts your buyer already reads
Not the biggest accounts — the ones your specific buyer follows. Turn on notifications for them. This list is the channel; your own timeline is not, yet.
- 03
Reply with something only you could say
Agreement adds nothing. Add the number you measured, the edge case that broke, the counter-example. Replies are how a new account reaches an audience it has not earned yet.
- 04
Post the work, not the milestone
"Shipped v2" is invisible. The screenshot of the thing that was broken, plus what it took to fix, gets read. Build in public means showing the mechanism, not announcing progress.
- 05
Daily for two weeks, then settle
Two weeks of daily activity is enough to find out whether your niche is there and whether you can sustain the register. After that, four times a week holds the ground without eating your build time.
What fails
The specific ways this channel goes wrong.
Posting into a following of zero and calling the channel dead
A new account's own posts reach almost nobody, which says nothing about the channel. Replies are the entry path; judge it after a month of those.
Growth-hacking threads about growth hacking
This attracts an audience of other people doing growth hacking, who will never buy your product. Follower count from the wrong niche is worse than no followers, because it makes the metrics lie.
Engagement pods and follow-for-follow
Inflates the numbers and destroys the signal, so you can no longer tell which posts actually reached buyers.
Only ever linking your product
An account that is entirely promotion gets muted rather than unfollowed, which means you cannot even see it happening.
What working looks like
Replies from named people in your niche, and profile visits after a reply lands. A single DM asking "does it do X?" is worth more than a hundred impressions.
Time cost
20 minutes a day, mostly reading and replying rather than writing.
X: common questions
Do I need a lot of followers before X is worth it?
No — replies work without them. A useful reply under a post your buyer is already reading borrows that account's audience, which is why a new account should spend its first month replying rather than posting.
Does building in public actually sell anything?
Indirectly, and slowly. It builds a reason for strangers to trust a name they have not heard of, which is what a cold landing page cannot do. Treat it as the thing that makes later channels convert, not as a channel that converts on its own.
Should I post the same content on X and LinkedIn?
Same story, different register. LinkedIn tolerates more context and a slower build; X needs the point in the first line. A copy-paste post reads as a copy-paste post on whichever platform it was not written for.
