SuperX

What they built

SuperX is a growth tool for people building an audience on X. It helps creators spot the post structures that go viral and replicate them, starting from a simple Chrome extension. Rob Hallam noticed that his own viral content was quietly driving clients to a dev agency he ran, so he turned that pattern recognition into a product. He partnered with Tibo Louis-Lucas to rebuild it, and Rob became the public face, shipping and posting the journey daily.

How they did it

This was Rob's sixth attempt after five products that went nowhere and a launch stretch so stressful it put him in hospital. What changed was distribution: about 95% of SuperX users came from Rob's own organic content on X, not ads. He used the product to grow on the platform, then documented the numbers openly, which pulled in more users who wanted the same results. Build in public was not a side activity here. It was the acquisition channel.

The numbers

SuperX crossed $1K MRR on the Chrome extension alone, hit $10K within weeks, and Rob posted himself shipping to a $12K MRR SaaS from Vietnam in November 2025 (source). By early 2026, Indie Hackers documented SuperX at $23K MRR with roughly 650 paying customers at $39 a month, six months after launch (source). These are founder-reported figures, so treat them as claimed.

What to take from it: your product can be its own best marketing. Rob built a tool for growing on X, then grew on X by using it, and let the audience watch the numbers climb. Five failures taught him the missing piece was never the code. It was getting seen.
