Excited to see this launch. I think it's a brilliant way for real people to have conversations in the context of whatever they're looking at on the web.

Tax ID Pro is an API that helps you validate tax ID numbers. I decided to build Tax ID Pro after manually confirming hundreds of tax ID numbers from various countries by hand and not having a decent way to validate them automatically. Lookup services are notoriously slow and expensive, so it's important to have a good validator on the front-end of your form so that no time and money is wasted...
