How I Built a $22K/Month SaaS Business: The SuperX Case Study

Description and use

A solo developer, hampered by travel fragmentation and zero income, built the SuperX SaaS, reaching $22K/month in 18 months. The pivotal factor was a focused three‑month residency in Colombia and integration with X’s creator ecosystem.

Problem

A solo developer struggled with fragmented travel and zero income for 12 months while building a niche SaaS tool.

Outcome

Rob Hallam transformed a $0 solopreneur effort into a $22K/month SaaS by eliminating travel fragmentation, focusing development in Colombia, and leveraging X’s creator ecosystem.

Workflow

• Settled in Colombia for a focused three‑month residency starting July 2025
• Developed core analytics engine during residency
• Shipped the Chrome extension
• Acquired early users via X creator ecosystem
• Established recurring revenue stream
• Scaled to 1,400 active users
