How the growth mechanism works

- Dictate in existing apps
- Build daily use
- Subscribe beyond free limits
Input tools are frequent-use products, but mistakes send users back to the keyboard. Demonstrations drive trial; accuracy sustains use. The latest funding announcement’s focus on error reduction and zero-edit output fits that retention requirement.

More about the founding and key events
Tanay Kothari and Sahaj Garg started Wispr in 2021 to develop hardware. Kothari says the team stopped that effort in July 2024 and focused on voice input software. Flow launched in September 2024, turning speech into text for computer work.
Kothari posted development updates and user stories on Reddit, LinkedIn and Twitter. Early users introduced it on YouTube and social media. In a 2025 interview, he described a free allowance of 2,000 words per week without an upfront card requirement, followed by payment for more usage. He reported roughly 90% organic acquisition and 20% paid conversion at that time.
The shift placed the product inside recurring work on computers people already owned. In August 2026, the company announced funding at a $2 billion valuation. Both founders had appeared on Forbes’ 2023 Under 30 list.
