Helix raises $6.2 million to verify humans with voice
Helix has raised $6.2 million in pre-seed funding and launched a voice-based platform that verifies human identity and age in under four seconds. The company says its biometric checks run entirely on the user’s phone, so data does not leave the device.
- Helix raised $6.2 million in pre-seed funding.
- Its voice challenge verifies identity and age in under four seconds.
- The company says biometric data stays on the user’s phone.
- Chicago Ventures led the round.
- Zeel is testing Helix as an early partner.
Voice challenge replaces heavier verification methods
Helix says its platform detects bots and predicts age from voice samples using a simple four-number voice challenge. It offers biometric-based identity verification, biometric multi-factor authentication and age assurance without storing biometric data or other personally identifiable information on a server.
The company positions the approach as an alternative to methods such as CAPTCHA, SMS and video selfies. According to Helix, those options can involve a tradeoff between lower friction and lower effectiveness, or greater security and a more cumbersome user experience.
Helix CEO and co-founder Alex Oberg said the company built the product to address consumer concerns about stolen personal information and the difficulty platforms face in determining whether an account belongs to a real adult or a synthetic agent. “Helix solves these problems by using voice to verify identity and doing so entirely on-device,” Oberg said.
Funding and standards support the launch
The funding round was led by Chicago Ventures, with participation from BAM Ventures, Aglaé Ventures, Corazon Capital, Tusk Ventures, Yonder Ventures, Rule30, Press On Ventures and Brown Angel Group. Helix also lists Dag Kittlaus, co-creator and CEO of Siri, among its advisers. Kittlaus said, “Helix is teaching them to understand the person speaking,” referring to machines.
Helix says it meets ISO/IEC 27566-1:2025, an international standard for age assurance systems, and is fully accredited by the Age Check Certification Scheme. It also says it is among the first companies certified under the IEEE Online Age Verification Certification Program.
The company connects that certification to New York’s SAFE for Kids Act, which it says takes effect in January 2027. According to Helix, the law requires independently certified age assurance and at least one age-checking option that does not require a government ID for platforms with an algorithmically driven feed.
Early partners are testing the platform
Helix is live with its first partners and is currently in beta with Zeel, an in-home health and wellness platform. Zeel founder and CEO Samer Hamadeh said the company is exploring Helix as it evaluates how trust and safety should evolve as AI creates new identity and verification challenges.
Platforms can integrate Helix through a software development kit or through a single line in Claude Code or OpenAI Codex deployments. The company says its zero-personally-identifiable-information architecture can be used in sectors including ticketing, dating, gaming, gambling and fintech.
Helix was founded by engineers from Ticketmaster, Tinder and Zillow. Its launch reflects a market looking for alternatives to identity checks that require government documents, video or centralized storage, while the company’s claims about speed, privacy and effectiveness remain its own.
