# Built by people who fought fraud at scale

We help platforms stop bad actors without ever learning who anyone is.

Our mission

## Platforms shouldn't have to choose between safety and privacy.

The internet is filling with bots, AI agents, and people who come right back after they're banned. The usual fix asks everyone for more: an ID, a selfie, a phone number. Good users pay in friction and data for what a few bad actors do.

Helix ends that tradeoff. We verify the person, not the paperwork, and we never learn who they are. Platforms stay accountable. Users stay anonymous.

Who we are

## We've sat in your seat.

Our team includes fraud and data science leaders from Ticketmaster and Tinder. One of us also helped create Siri. Now we’re building the voice check we always wished we had.

### Verified Fan

Built the bot protection platform Ticketmaster acquired in 2017.

### Zillow

Led data services and a team of more than 100 engineers.

### Tinder

Built the original matching algorithm and the first data team.

Leadership

## The people behind Helix

### Alex Oberg

Co-founder & CEO

Sold his first startup to Ticketmaster in 2017 (via Techstars Boston), which became Verified Fan, the world’s largest bot protection platform. Alex spent the years after watching the same defenses he helped build get steadily defeated by AI, and started Helix to do it right the second time.
