Miravoice raises $6.3M seed for structured, long-form AI voice-interview surveys

Source: Crunchbase News · Apr 2, 2026

Miravoice has raised a $6.3 million seed round, led by Unusual Ventures, to build voice agents purpose-built for a specific and demanding interview format: long-form, highly structured quantitative phone surveys running 120-plus questions over 40-plus minutes. That's a meaningfully different problem from most conversational voice-AI products, which tend to optimize for short, adaptive exchanges — Miravoice is optimizing for consistency and structure across a long session instead.

The target market is market research and polling rather than hiring, which puts it adjacent to, rather than directly competing in, our core interview-data segment. But the underlying technical problem — running a long, rigidly structured, voice-based interview at scale while keeping data quality consistent across thousands of sessions — is close enough to be worth tracking. Structured long-form voice interviews are exactly the kind of interaction that generates rich, comparably formatted conversational data.

Miravoice's focus on structure and consistency at length, rather than open-ended conversation, is a useful reference point for how much demand exists for rigorously structured voice-interaction data outside of hiring specifically — a signal the addressable market for this kind of data may be broader than the hiring-tech category alone.

• $6.3M seed round led by Unusual Ventures
• Voice agents built for long-form, highly structured quantitative phone interviews
