- The platform helps teams manage usage-based, hybrid, and custom pricing models with real-time transparency, entitlements, and developer-first APIs.
- Backed by TDV Partners, angel investors & operators from Magicpin, Zomato, Innovaccer and Aftershoot, Flexprice is building the complete monetization stack for AI and Agentic companies.
Flexprice, the open-source billing and metering platform built for AI and Agentic companies, has raised $500,000 in pre-seed funding led by early stage VC firm TDV Partners.
The round also saw participation from seasoned operators and angel investors from Brij Bhushan (Co-founders, magicpin), Gunjan Patidar, Ram Singla and Pradyot Ghate (leadership, Zomato), Sandeep Gupta (Co-founder, Innovaccer), Akash Singh (ex-Co-founder, Observe.AI), and Harshit Dwivedi (Founder, Aftershoot).
With the new funding, Flexprice will expand its engineering team, accelerate integrations with popular payment gateways, and deepen its open-source offerings as it builds the modern billing stack for AI and Agentic companies.
Solving a new-age billing bottleneck
The AI boom is fundamentally reshaping monetization strategies. Over two thirds of SaaS companies are now launching or integrating GenAI features, dramatically increasing infrastructure costs and altering customer value perception. To adapt, a majority of SaaS and API-first businesses are shifting away from static subscriptions in favor of usage-based or hybrid billing models that better align pricing with actual customer usage.
However, legacy billing tools, built for a predictable, seat-based SaaS world, struggle to meet the demands of today’s dynamic, metered AI and API-first business models. As a result, engineering teams end up spending months building and maintaining complex infrastructure for metering, entitlement gating, usage aggregation, and billing logic, creating costly bottlenecks and diverting resources away from core product development.
Flexprice is addressing these challenges by offering developers a modular billing layer that helps launch and scale usage-based, hybrid, or custom pricing without needing them to reinvent the wheel. With its plug-and-play architecture, the platform integrates directly with popular payment providers like Stripe, Adyen and Razorpay helping teams skip months of engineering effort and eliminate vendor lock-in.
“Today’s AI and Agentic teams need to move fast as the competition on product distribution goes up, ability to move fast with pricing and scalable billing plays a critical role. Flexprice is built to ensure pricing, packaging and billing are never a bottleneck” said Manish Choudhary, CEO of Flexprice. “We built Flexprice to give developers control, flexibility, and peace of mind.”
Key Features of Flexprice:
- Open-source, self-hostable architecture for transparency and control.
- Developer-first APIs and SDKs for real-time usage tracking, event instrumentation, and quota gating
- Support for any pricing model, including pay-as-you-go, credits, seats, or volume tiers
- Real-time analytics dashboards and invoice visibility for customers and internal teams
- Composable design that works as a metering layer or a full billing engine
Built for the AI-First Economy
The total addressable market (TAM) for modern AI billing infrastructure is estimated at $4 billion, growing at 20% CAGR, driven by the rise of generative AI, API platforms, and real-time analytics. Flexprice is targeting both the 70,000+ “AI-native” startups worldwide and large enterprises evolving their AI monetization models.
“We believe open infrastructure is the future,” said Nikhil Mishra, CTO of Flexprice. “Our goal is to make modern billing accessible, composable, and cost-effective – whether you’re an early-stage AI startup or a scaling business.”
Founded in 2025, Flexprice’s founding team includes former product and engineering leaders from leading AI and consumer tech companies. The startup is already working with early-stage AI companies building LLM tools, search infrastructure, and real-time analytics engines.
“We believe Flexprice is solving a fundamental infrastructure gap in the monetization stack for AI and Agentic companies,” said Ujwal Sutaria, General Partner at TDV Partners. “The team’s open-source-first approach, deep developer empathy, and modular product vision give them a unique edge in a rapidly expanding market.”
