Voice is the oldest interface people have, and the one they trust least online. Helix thinks it can change the order of those two facts.
The startup has raised $6.2M in a round led by Chicago Ventures, with BAM Ventures, Aglae Ventures, Corazon Capital, Press On Ventures and Tusk Ventures among the participants. Siri co-founder Dag Kittlaus backed the company and will advise it.
Its model runs on the handset itself. By analysing a few seconds of speech, Helix claims it can tell whether a human or a bot is speaking, estimate the person’s age, and do it without shipping raw biometric data off the device.
From ticket bots to cheap identity checks
Alex Oberg, who co-founded Helix in 2025 with Anna Dorofiyenko and Mike Hall, spent years fighting scalpers at Ticketmaster on the Verified Fan system. His argument now is that generative AI has made older proxies for identity – email addresses, phone numbers, device fingerprints – close to useless.
Because the model is compressed enough to run on hardware as modest as an iPhone 13, Helix pitches its checks as nearly free to deploy: a replacement or supplement to the puzzles websites ask visitors to solve. In-home healthcare provider Zeel already uses it to confirm the caregiver at the door is the person scheduled.
The company is piloting voice as a health signal, testing whether the same model can flag intoxication or distress. That claim invites scrutiny before it invites customers, and Helix concedes its technology cannot yet reliably detect AI agents on live calls.
Kittlaus argues the compression work gives Helix a cost advantage as voice fraud climbs. Investors are betting cheap, local identity checks become a default layer rather than another app people install.
