Best Tools for Monitoring AI Spend in a Startup?

The demand for monitoring AI expenses is definitely on the rise! Managing spend can be tricky since it’s often divided among various services like API calls to OpenAI or Google, GPU instances for training, and managed services like SageMaker. A good starting point is to ensure you set up billing exports with labels for each department, which will make it easier to analyze your costs. If you’re using third-party APIs, they won’t show up on your cloud bill, so it might be a good idea to track those separately using API dashboards or even create a simple proxy to log usage by team.

Honestly, for a small company like yours, I suggest just using the native billing dashboards offered by the AI services you’re already using, like OpenAI or Anthropic. They usually offer pretty good usage breakdowns based on API keys or individual users. If you're working with multiple vendors, Azure Cost Management can help consolidate spending across different services, especially if you're using Azure OpenAI. Otherwise, exporting your billing CSVs monthly and managing that in a spreadsheet could also work. The more advanced FinOps platforms can be overkill and quite pricey for your startup size, so I'd recommend saving that budget and just setting up some basic alerts in those native dashboards instead.
