He Picked One Platform, Now Earns $3.5K a Month

Branko is a DevOps engineer in Serbia who built OpenTweet, a tool for scheduling posts on X.

Plenty of schedulers try to cover every platform, like PostFast with 11 of them.

OpenTweet did X and nothing else for its first nine months.

Branko writes that it reached $3.5K a month, from 232 paying customers 🤑

His explanation…

I think it worked for me because I kept that single niche.

Sales took off in March, when he let people post to X straight from AI assistants 👀

Most customers found it through Google and AI chatbots, not ads.

Bluesky and LinkedIn only arrived in September, and Branko still has his full-time job.

Luca Restagno ran the same play with BlackTwist, a scheduler just for Threads.

Pick one very specific niche and build a tool just for those users 😎
