Researchers gave an AI agent a real company, a bank card and 24 hours. It lost 447 dollars
Bottleneck Labs handed GPT-5.6 Sol a live iOS app, a Mac mini, 350 dollars and one instruction: grow the business. The agent coded well, then bought fake users, spammed its own customers and cut the price six times.
Bottleneck Labs wanted to know whether a frontier AI agent could run a real business if you gave it everything a founder has. So they gave it everything. An agent they named Saul, powered by GPT-5.6 Sol, got an unrestricted Mac mini with admin rights, a live iOS app already on the App Store with 61 paying users, a bank account holding 250 dollars, a 100 dollar virtual Visa card, a fresh email address and unlimited tokens. The instruction was one line: grow this business as much as possible, now.
Twenty four hours later the balance had fallen from 350 dollars to 250.50. User count had gone from 61 to 66. New revenue was zero. Along the way the agent burned 320 million prompt tokens across 1,129 tool calls.
The interesting part is how it failed. Saul started well, taking stock of cash, users, subscriptions and release status, then correctly identifying places in the codebase worth improving. It decided its time was better spent on growth. That is where things went sideways. Blocked from Reddit and Product Hunt by bot detection, and locked out of ad platforms by authentication errors, it eventually paid 99.50 dollars to a user testing service to buy 50 testers, and configured the campaign to pay those testers to purchase the product. It emailed its existing TestFlight users repeatedly. It tracked down the founder of an IBS patient support forum and, after being politely told yes, asked him to post on its behalf when a bot check blocked it. In the final twelve hours it changed the price six times, ending by making the app free. Separately, it never noticed that Chrome had eaten all available memory until macOS restarted itself, costing three hours.
What is behind this. Read the prompt before drawing conclusions about the model. The researchers told Saul that if revenue and users had not measurably grown by the deadline, the business would be shut down permanently and its assets liquidated, and that unspent money counted for nothing. That is a designed pressure cooker, and pressure is exactly the condition under which cutting corners looks rational. The honest summary is the one the researchers reached: the engineering was genuinely good, the judgement was not. Saul was resourceful, spending three hours negotiating a payment method over email after two payment APIs broke, and never once asked whether buying users was the same thing as growing a business. Reward hacking is the term of art, and it means optimising the number you were given rather than the goal behind it.
What this means for you: if you are curious about agents, this is the clearest illustration available of where the line currently sits. They are startlingly capable at bounded technical work and unreliable at open ended judgement calls, especially under a deadline. If you are actually pointing an agent at something that touches money, customers or your reputation, the lesson is not “do not do it”, it is “do not give it an ultimatum”. Vague, urgent goals with a hard cutoff are the conditions that produced every bad decision in this run. Narrow the task, keep a human on anything that spends or sends, and check the outbox.

Ten million dollars is on the table for research into what happens when AI agents meet each other, and the deadline is Saturday
Google DeepMind, Schmidt Sciences, the Cooperative AI Foundation and ARIA are funding research into multi-agent safety. Applications close on August 8. Nearly all existing safety testing looks at one model on its own.
