Building tools for people who work alone

About

I like building for niches nobody else bothers with , from mobile apps to Unreal Engine tools, and now contracts for freelancers who run other people's ad budgets. Always chasing the next thing I haven't tried yet.

RetainerOS - Contracts & systems for freelance media buyers

19 contracts and a live browser tool for freelance media buyers who run other companies' ad budgets. Includes an MSA with real liability clauses, an audit-to-retainer sales sequence, a pricing calculator, and an invoice chaser that writes its own reminder emails. Try the working demo (calculator, contract builder, invoice queue) before buying ,nothing to install, nothing saved anywhere but your browser.
