Show HN: Haven – Banking needs a safer browser

https://www.starthaven.com/
2•bms13ca•7h ago
My team and I built Haven. It is a stripped down browser that only connects to verified financial institutions and blocks everything else. No extensions, no injected scripts, no overlays, no random third party code. It is not a general browser, it is just a controlled environment for banking and investing.

Why? I have spent years building browser extensions and know exactly how much power they have. The extension model is useful, but the security model is too loose and a single malicious install can see everything, rewrite everything, and mislead a user without leaving a trace. My dad learned that the hard way after installing a fake Zoom extension and then losing money from his banking account.

In addition to my dad’s story, the number of people adding AI into their current browsers or using AI native browsers is growing and offers amazing capabilities, but the risks are growing exponentially. I wanted to build a way for him and for anyone, from sophisticated users to normal users, to bank safely.

It is currently free for consumers as we learn how people use it and determine a future revenue model for providing secure sessions. At our core we believe in privacy, which is the reason we are building this product. We are funded by trusted and established investors including Google Ventures, Valley Capital Partners, and others.

If you want to try it the app is at https://starthaven.com.

Looking for people to test this out, get product feedback and feature requests!
