TDV Partners sponsored a $500K pre-seed investment for Flexprice, an open-source invoicing and metering platform for AI and agentic businesses.
The money raised will go toward growing its open-source offering, adding payment connectors, and enlarging its engineering staff. With a modular stack that facilitates real-time billing and adjustable pricing, the business aims to capture the $4 billion AI billing infrastructure industry.
Angel investors and operators from Magicpin, Zomato, Innovaccer, and Aftershoot also participated in the round.
Flexprice was established in 2025 to assist SaaS and API-first companies in implementing custom, hybrid, and usage-based pricing models.
Teams can manage entitlements, measure usage, and increase monetization without having to construct internal infrastructure thanks to its platform’s developer-first APIs, real-time analytics, and interfaces with Stripe, Razorpay, and Adyen.
Platforms such as Metronome, Orb, and Lago are competitors of Flexprice in the billing infrastructure market.
