We're also working in the billing space with a complementary tool, Tier (https://github.com/tierrun/tier). Although we currently do not support Lago directly, it's exciting to see more options emerging. Their content marketing has been particularly impressive on HN and in general.
With metering, entitlement management, CPQ, feature gating, and everything else required in a modern SaaS company, the PriceOps space can be quite complex for developers.
Congratulations on the launch and best of luck!
