Helix raises $6M for voice checks that prove you are human

[Brandon14]

A startup is using voice to tell people apart from AI bots. TechCrunch reports that Helix has raised $6 million in a round led by Chicago Ventures, with Siri co-founder Dag Kittlaus investing and joining as an adviser

Helix was founded in 2025 by Alex Oberg, Anna Dorofiyenko and Mike Hall. Its verification is a four second voice challenge

The check runs locally on devices as old as the iPhone 13. Keeping processing on the device helps with privacy

Customer Zeel uses Helix to verify providers visiting customers' homes. Making sure the right person turns up is a practical use case

As AI makes fake voices and bots more convincing, simple ways to prove someone is human will become more valuable. Running the check on the device is a sensible privacy choice. Having a Siri co-founder involved gives the company useful credibility

Would you trust voice verification to prove you are human? And how worried are you about AI bots pretending to be people?
