Frontier.sh
Build software that stands the test of time

I'm Marc. I've been building successful software for twenty years.
For nearly two decades, I worked alongside the same founder, building everything as his sole developer. Together we created apps, industry-defining video marketing platforms, and eventually ThriveCart, which we scaled to process over $1.6 billion for our customers before its acquisition.
That track record taught me what everyone gets wrong: you don't need a big team to build and scale. You need solid architecture, fast decision making, and discipline.
AI is a force multiplier, and added to my years of experience being lean and efficient, I'm building faster than ever.
Today I run Frontier.sh, building my own products and working with select founders who want to maximise their output without bloating their team or losing control of their code.
Asynchronous coding agent to break you free from your IDE.
Conversion-focused checkout platform for digital products.
AI-powered support desk built for small, lean teams.
Major platform rewrite for a high-growth procurement startup.
AcquiredCart platform that processed $1.6B+ for 35,000 customers.
