My startup accidentally spent $30,000 on AI tokens in a month. It was worth it to move fast — but we found a simple fix.

In the fast-paced world of AI development, financial missteps can happen, as demonstrated by the experience of Turbo AI, a startup co-founded by 21-year-old Sarthak Dhawan. Recently, the company faced an unexpected surge in expenses, accumulating nearly $30,000 in AI token costs within a single month. However, Dhawan views this costly lesson as part of their broader strategy to innovate and grow. Dhawan, who plays a pivotal role in the startup, recounts how his team’s aggressive approach to shipping new features contributed to the spike in spending. The co-founders, Dhawan and Rudy, launched their AI learning tool app while still in college, ultimately deciding to drop out to focus on their business full-time. For them, the urgency of momentum outweighs the financial implications of higher token usage. The startup's AI expenses have increased as more team members engage with AI tools for various tasks, with an average monthly expenditure of around $20,000. In April, however, Dhawan accidentally left a specific setting—known as fast mode—active in their AI coding tool, Claude Code, leading to the inflated bill. This mode, while enhancing speed, also significantly raises costs. After realizing the oversight, Dhawan and his team have adjusted their approach, opting to use fast mode selectively, only when speed is critical. This tweak allowed them to maintain productivity without incurring unnecessary expenses. Dhawan emphasizes that while they keep an eye on costs, they prioritize the productivity gains that AI tools offer. As Turbo AI continues to grow, the team remains committed to leveraging AI for software development, believing that investing in productivity will ultimately yield long-term benefits for the business. With their sights set on future innovations, Dhawan reflects on the balance between speed and budget management, viewing challenges as opportunities for learning and growth.
