Yep - we're free for the first 100 users!

What should I do to get my personal financial info? I signed up but the interface presented is one of an app maker not for end user

That is exactly what Plaid is... a tool for developers. Savvy users can use the Plaid API to build apps that use their users' financial data.

It's free to use if you have less than 100 users, so you could easily build your own tool to manage your personal data for free.

Neat! Def gonna check it out.

Wait, you just got $44 million in funding and you don't have 100 users yet?

Assuming this isn't a joke, he means if you were to build something with their api, it is free to you up to your 100th user.

Oh, right, now I understand.

I believe that would 100 users for the service that you would write using their api. See bottom of this page: https://plaid.com/products/ (playing around with the api to help make a self-use budgeting app - under the current terms, this use case would be free).

I think we may have set a record if that was the case...

But the other commenters are correct - the first 100 additions to the api are free.
