Hey! Johan, co-founder of Castle here. My and my co-founder used to work in a financial startup and couldn't find any easy-to-use solutions for account monitoring. We built Castle to be a drop-in solution against account compromise. You track events in your web and mobile apps, and we analyze device, location and usage patterns to make sure they are consistent for each user.

We have lots of plans for improving the product: more 3rd-party integrations, built-in 2FA/captcha, APIs to build your own "security page" with device and session history. Would love to hear the feedback from the HN community!

I'm curious what verticals your customers are in. Unless your company is liable for account takeover it seems like this is a tough sell.

The risk of FPs and the lack of clear benefit to the company paying you you seems like a hard place to make money.

Thanks, this is valid feedback. You're right, account takeover is not the best description unless you're a big financial institution. When working with startups they use us for the (risk-based) authentication, and we're working in that direction, offering 2FA flows, security emails among other things.
