How I Used Twitter to Hit $10K/Month
Laid-off engineer Rob Hallam shipped five products that made $0 in 2.5 years while posting on X. A viral post about those failures got him his first $3K dev-agency client, and all agency clients came inbound via X. He then co-founded SuperX (X growth tool, $29/month) with Tibo. It launched July 2025; a selfie post beat the product launch post and added $1K MRR in 24h. SuperX reached ~$13K MRR (450 subscribers, +25% MoM), with 95% of traffic from Rob's X account (~100K impressions/day, 34K followers). He gives a 7-step build-in-public playbook.
