One founder, 15 Devin agents, $20,000 in a month
Ryan Carson runs his family law software company alone, with a fleet of cloud coding agents and a handwritten to-do list. Here is how the setup is organised and what it costs.
Ryan Carson is the solo founder of Untangle, a B2B software platform for family law firms. He says he spent $20,000 on Devin, Cognition's cloud coding agent, in a single month.
He runs 15 of those agents at once, on his account. They cover engineering work, customer success and investor updates.
The control system is deliberately low-tech. Carson describes managing the fleet with a folder structure, priority threads and a piece of paper, rather than a dashboard.
That is the first transferable idea. The bottleneck in running many agents is not compute, it is the founder's own attention, and a paper list forces a single ordered queue.
The second is the review loop. Carson says a skill he calls LAN PR handles roughly 40 pull requests a day, with a video walkthrough and auto-merge, and no QA person reviewing any of them.
The third is monitoring. He describes a playbook called Watchdog that tracks every law firm account and stands in for a customer success team, with error monitoring feeding into it.
The stack is not one tool. Carson says he has moved off local agents almost entirely and reaches for OpenAI's Codex in one specific situation, with Devin and Claude Code taking different jobs.
For design work, he describes writing a specification in Markdown using Claude Design and then handing it to Codex to build.
Hiring is being run the same way. Carson says he is recruiting his first engineer without a phone screen or a formal interview.
None of these claims have been independently verified. They are one founder's account of his own setup, given on Claire Vo's How I AI podcast, and the $20,000 is what he says he spent, not an audited figure.
The most useful part for anyone tempted to copy the spend is what Carson says he concluded. More output from more agents does not produce a better product.
He also says he got away from his computer, met a customer in person, and changed the product's direction as a result. Untangle's positioning had already shifted once, towards divorce, before that.
So the practice worth stealing is cheaper than $20,000. Keep one ordered list, automate the review loop before you scale the number of agents, and go and talk to a customer before you buy another seat.
