Ran an AI agency for a bit before building TokenVault, and the same problem kept showing up: every client project meant a new OpenAI key, a new Anthropic account, a new billing dashboard, a new rate limit to babysit. By month three you're managing 6 different provider logins just to ship work.

The actual fix isn't 'use fewer models' — clients want the best model for the job, not the one that's easiest for you to bill. The fix is pooling access: one subscription, one usage dashboard, keys that are already provisioned and rate-limited sanely, so you can drop a new client project in without opening a new tab.

That's the whole thesis behind TokenVault — shared, managed LLM API access for agencies who'd rather spend time on client work than provider admin. If you're running client AI projects and tired of the account sprawl, worth a look.
