AI Platform Miravoice Raises $6.3M Seed Round

San Francisco startup Miravoice has completed hundreds of thousands of production calls for market research firms; Unusual Ventures led the round.

Miravoice, a San Francisco-based voice AI platform built for structured phone surveys, disclosed a $6.3 million seed funding round on April 2, led by Unusual Ventures with participation from Neo and 25madison. The capital will fund engineering hires and platform scaling to support tens of millions of calls, the company said.

The round drew angel investors including Karim Atiyeh, chief technology officer at Ramp; Rajeev Goel, chief executive of PubMatic; and Amar Goel, chief executive of Bito AI, alongside executives from Atlassian, Crusoe, and Google.

Miravoice builds voice agents that conduct long-form, rules-based phone surveys, replacing human interviewers at call centers. The platform handles branching logic, question randomization, and multilingual outbound and inbound calling without requiring the user to write code. The company said it has completed hundreds of thousands of production calls for market research and public opinion polling firms.

For many organizations, live phone calls are still the gold standard for understanding what people think and do, but they’re too expensive and time consuming.
Miravoice co-founder & CEO Nishant Jain. 

Jain added that the platform can conduct hour-long surveys without hallucinating, follow complex interviewing rules, and never get tired or impatient. 

The move comes as response rates in traditional telephone surveys have declined and research budgets at market research firms have tightened. Human interviewers and third-party call centers remain the standard for large-scale quantitative polling, making the work costly to run and difficult to standardize at volume.

Miravoice’s no-code interface lets non-technical teams upload questionnaires, configure logic rules, and launch call campaigns without internal engineering support. The company said its proprietary architecture is built specifically to keep AI-driven conversations on a structured track, a requirement distinct from open-ended interview tools that allow a wider conversational range.

Lars Albright, general partner at Unusual Ventures, said in the press release that high-quality, representative data is becoming harder to obtain as response rates fall and budgets tighten. He described the market research use case as one of the most labor-intensive areas for AI applications.

Jain confirmed the funding on LinkedIn on April 2, noting that the platform has presented research at industry conferences demonstrating survey performance exceeding 120 questions with branching logic and respondent disruptions. 

It is unclear whether Miravoice is currently operating under a subscription or purely usage-based pricing model, or what its current headcount is. The company said it is actively hiring engineers in the Bay Area. Miravoice is headquartered in San Francisco.
