Mind the Compute

Every customer request, internal agent and experiment can now carry its own bill. The financial habits most founders inherited were built for a different kind of business.

In a typical software company, the largest cost was people, and serving one more customer cost very little. AI has changed that. Costs rise and fall with usage. Model prices and capabilities can change within months. You may be asked to pay for compute in advance before you know what demand will look like, or to decide whether a tool will replace a hire, support one or simply add another subscription.

Mind the Compute is a practical finance guide for early-stage founders whose costs depend on AI and who make financial decisions without a full-time finance lead. It explains the financial foundations in plain language and applies them to the decisions AI now puts in front of you.

• Understanding what AI really costs, per successful outcome
• Building a team you can afford: people, AI or both
• Choosing a model strategy: use, adapt or train
• Pricing a product whose costs change with usage
• Planning compute: when to commit and when to stay flexible
• Funding hardware across long supplier lead times
• Checking whether automation actually paid off

Drawing on real client cases and clearly labeled worked examples, each chapter connects cost, cash, unit economics and commitments to a decision you can make with your own numbers. A closing chapter turns them into one decision log and a simple review rhythm.

Each practical chapter comes with a companion tool in the Founder Toolkit, also available as a connector for AI assistants such as Claude.
