Usage-based billing startup Flexprice has raised $1.5 million in a seed funding round led by Shastra VC, with participation from TDV Partners and People Group founder Anupam Mittal. The fresh capital will be used to expand in the US and Europe and build products beyond billing, including metering, revenue recognition, and financial reporting tools. Founded in 2024, Flexprice builds open-source billing infrastructure for AI-native and API-first companies. Its platform is being used by AI companies to manage billing across API calls, token usage, GPU hours, and hybrid pricing models. According to the firm, its revenue grew 6X in the last quarter, while event processing volume increased 20X over the past year to more than 20 billion events per month. The company is headquartered in New Delhi and has teams in Bengaluru and San Francisco.
