Branko
- Founder of OpenTweet
- $3,500 monthly revenue
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
