Flexprice has announced a $1.5 million seed funding round led by Shastra VC, with participation from Anupam Mittal and TDV Partners, which also increased its earlier investment in the company.
The New Delhi-headquartered startup is building open-source usage-based billing infrastructure designed specifically for AI-native and API-first enterprises.
The company said the fresh capital will support:
- Global expansion across the US and Europe
- Product development beyond billing infrastructure
- AI-native finance automation capabilities
- Revenue recognition and financial reporting systems
Flexprice Targets AI-Era Revenue Infrastructure Challenges
As AI companies increasingly shift toward:
- Usage-based pricing
- Token-based billing
- API-driven monetisation models
traditional subscription billing systems are struggling to support modern enterprise requirements.
Flexprice said AI businesses now operate with:
- Rapidly changing usage patterns
- High infrastructure costs
- Complex pricing structures
- Real-time consumption tracking needs
The company believes legacy billing platforms built for flat-rate SaaS subscriptions are no longer suitable for AI-driven software models.
Company Reports Strong Growth Momentum
Following its initial funding round in July 2025, Flexprice said it has entered its strongest growth phase so far.
According to the company:
- Revenue grew 6X in the last quarter
- Event processing volume increased 20X over the past year
- The platform now processes over 20 billion events per month
The infrastructure currently powers usage-based billing systems for several fast-growing AI companies globally.
Flexprice’s platform supports:
- Token consumption tracking
- API usage billing
- GPU-hour metering
- Hybrid pricing models
- Enterprise-scale financial workflows
AI Companies Demand Flexible Billing Systems
The company highlighted growing challenges faced by AI startups and enterprises as pricing models evolve from:
- Seat-based subscriptions
to - Usage-based and outcome-based pricing systems
“If billing doesn’t work, we don’t make money. Flexprice lets us focus on the core business instead of building billing as a second product,” said Shubhendu Shishir, Head of Engineering at Simplismart, an AI infrastructure SaaS platform.
Investors See Major Opportunity in AI Revenue Infrastructure
Avijeet Alagathi, Managing Partner at Shastra VC, said the investment was driven by the growing complexity of AI-era monetisation systems.
“In our conversations with AI companies, one theme came up repeatedly: traditional billing systems are breaking under new AI business models. Software pricing is rapidly shifting from seat-based subscriptions to usage-based and increasingly outcome-based pricing, creating a level of complexity most existing infrastructure wasn’t designed to handle,” said Alagathi.
He added:
“What stood out about Flexprice was the strength of the engineering vision – an open-source, real-time billing platform purpose-built for modern AI products, while integrating cleanly into existing systems. The early traction reinforced how urgent and universal this need is. We invested because we believe Flexprice is building foundational infrastructure for the next generation of AI-native software companies.”
Open-Source Infrastructure Designed for Enterprise AI Workloads
Flexprice said its platform was built specifically for high-volume AI workloads and enterprise-scale event processing.
The company’s infrastructure includes:
- Open-source self-hostable architecture
- Real-time usage ingestion systems
- Developer-first APIs and SDKs
- Workflow orchestration capabilities
- Real-time analytics dashboards
- Customer invoice visibility tools
The platform also integrates with:
- Stripe
- Adyen
- Razorpay
Flexprice stated that its architecture is built using:
- Go
- ClickHouse
- Kafka
- Temporal
to support:
- High-throughput metering
- Event-driven pipelines
- Enterprise-grade precision and scalability
Company Plans to Expand Beyond Billing
Manish Choudhary, CEO of Flexprice, said the startup’s long-term vision extends beyond billing infrastructure.
“Billing is the hardest layer to get right, and the most consequential when you get it wrong, so that’s where we started. But billing is just the foundation of a much larger stack that every software company runs on,” he said.
He further added:
“The bigger picture is full revenue automation: from the first usage event to the last dollar recognized, giving AI companies the infrastructure to experiment, iterate, and scale their monetization in real time without being held back by systems that were never built for them.”
Growing Market Opportunity for AI Billing Platforms
The company estimates the global market for modern AI billing infrastructure at:
- Approximately $4 billion
with projected growth of:
- 20% CAGR
Meanwhile, the broader SaaS billing market is expected to reach:
- $20.3 billion by 2033
Flexprice aims to serve:
- AI-native startups
- Enterprise SaaS companies
- API-first software platforms
- Global technology businesses transitioning to AI monetisation models
Industry estimates suggest there are now:
- More than 70,000 AI-native startups globally
creating increasing demand for scalable revenue infrastructure systems.
Investors Highlight Shift Toward Usage-Based Software Models
Ujwal Sutaria, General Partner at TDV Partners, said AI is fundamentally changing how software products are priced and delivered.
“We’re seeing a generational shift in how software is priced and delivered, driven by AI and usage-based models. Flexprice is building the foundational infrastructure required for this new paradigm,” he said.
He added:
“Their open-source approach, combined with deep technical execution and a clear product vision, positions them to become a category-defining company in the revenue stack.”
Conclusion
Flexprice’s latest funding round highlights growing investor interest in AI-native infrastructure platforms as enterprises increasingly shift toward usage-based monetisation models.
As AI adoption accelerates globally, modern revenue infrastructure capable of handling real-time pricing, metering, and financial automation is expected to become a critical component of enterprise software ecosystems.
The company’s focus on open-source architecture, enterprise scalability, and AI-driven billing workflows positions it within one of the fastest-growing segments of the global SaaS and AI infrastructure market.
