Flexprice raises $500K in pre-seed round led by TDV Partners

Flexprice, an open-source billing and metering platform for AI and Agentic companies, has raised $500K in a pre-seed round led by TDV Partners. 

The proceeds will be used to expand its engineering team, add payment integrations, and grow its open-source offering. The startup targets the $4 billion AI billing infrastructure market with a modular stack that supports flexible pricing and real-time billing.

The round also saw participation from angels and operators from Magicpin, Zomato, Innovaccer, and Aftershoot.

Founded in 2025, Flexprice helps SaaS and API-first businesses implement usage-based, hybrid, and custom pricing models. 

Its platform offers developer-first APIs, real-time analytics, and integrations with Stripe, Razorpay, and Adyen, allowing teams to track usage, manage entitlements, and scale monetization without building internal infrastructure.

Flexprice competes with platforms like Metronome, Orb, and Lago in the billing infrastructure segment.
