Tarini Padmanabhuni, aged 21, leads DetectifAI to develop tools that verify human speakers and identify synthetic audio in live calls, striving to protect digital trust amid the rapidly expanding deepfake market.
Tarini Padmanabhuni’s interest in machine learning began in class six, but it was a fraud attempt involving her grandfather that gave that interest a sharper purpose. The 21-year-old entrepreneur now leads DetectifAI, a start-up building tools to verify human speakers and identify synthetic audio in real time, with the aim of stopping deepfake scams before they can do damage.
Padmanabhuni told YourStory that the incident made clear the threat was wider than a technical challenge. AI-generated voices, she said, can be used against families, banks, customer service teams and identity systems, undermining digital trust at scale. Founded in 2025 and based in San Francisco and Bengaluru, DetectifAI is designed to detect manipulated speech patterns and audio deepfakes, particularly in live calls, where the company says speed matters most. Its models run on devices and at the network edge, allowing suspicious callers to be flagged without sending data to the cloud first.
The start-up is targeting sectors where voice authentication remains central, especially banking, financial services and insurance, as well as healthcare. Padmanabhuni, who studied computer science with a specialism in cyber-physical systems at MIT Manipal, said she has five patent applications pending in deepfake detection and has spent the past two years developing practical AI tools for synthetic media analysis. DetectifAI currently has a team of 10, and its broader ambition is to create a trust layer for digital interactions across phones, computers and enterprise systems.
The company has raised seed funding from investors including Josh Constine, the former TechCrunch editor-at-large, and Silicon Valley investor Manohar Kamath, though it has not disclosed the amount. Padmanabhuni said the funding helped build early momentum, but she also pointed to the role of the Sam Altman-backed founder programme The Residency in San Francisco, which she said opened doors to more useful connections. Her longer-term pitch is ambitious: she wants DetectifAI to become for audio trust what Dolby is for sound quality. Her timing may be favourable. Coherent Market Insights says the global deepfake market could reach $7.44bn in 2026 and rise to $32.58bn by 2033, while Grand View Research forecasts rapid expansion in both the global market and the US segment, where software is expected to account for a large share of growth.
