TL;DR: Metronome has raised $50M in Series C funding, bringing total funding to $128M. In December 2024 alone, we 8x’d dollars billed YoY and now power billing for 150M+ end users, processing billions in usage-based revenue. OpenAI, Anthropic, Databricks, Confluent, and NVIDIA rely on Metronome as their growth engine to ship faster, give customers better visibility and control, and scale revenue at breakneck speed —without billing limits, inefficiencies, or roadblocks.

The software industry is at a pivotal moment. AI is redefining how businesses deliver value, monetize products, and drive growth. At the center of this transformation lies one of the hardest challenges software companies face: aligning pricing with the value they deliver.

Metronome is leading the shift in modern billing, transforming how companies monetize in a world where value is dynamic, personalized, and measurable. Unlike traditional subscription billing, usage-based billing goes far beyond processing recurring invoices—it’s a strategic growth lever that ties pricing with value, builds customer trust, and drives smarter revenue decisions.

Building internal billing systems takes years. Metronome eliminates that burden, giving companies the speed, flexibility, and reliability to scale without limits. Instead of wrestling with complex billing infrastructure, companies can focus on refining their business models, accelerating growth, and staying ahead.

The shift toward usage-based pricing is fueling our explosive growth. In December 2024 alone, we 8x’d growth in dollars billed YoY. Today, we power billing for more than 150 million end users and have processed billions in usage-based revenue. In October, we launched Metronome 2.0—the most flexible and scalable billing platform, enabling category leaders like OpenAI, Anthropic, Databricks, Confluent, and NVIDIA to ship faster, give customers better visibility and control, and scale revenue at record speed, all without the headaches of billing limitations or operational slowdowns.

Usage-based pricing isn’t the norm for AI-native products alone—it’s reshaping traditional subscription models into hybrid structures. More companies are adding usage elements, combining recurring subscriptions with variable pricing. In fact, over 85% of companies are adopting some form of usage-based pricing. Metronome is the only billing platform that makes this shift possible, giving customers the flexibility, speed, and scale to succeed. Investors are doubling down on this momentum, driving our $50 million Series C funding round led by NEA with participation from a16z, Greyhound Capital, General Catalyst, and Workday Ventures. With this latest investment, our total raised now stands at $128 million—solidifying Metronome as the billing engine for the AI-driven, usage-based economy.

AI’s pricing revolution: Why modern billing matters

AI is driving the next wave of pricing transformation, shifting businesses away from static subscription- and seat-based models to dynamic, usage-based, and outcome-driven approaches. These models aren’t just innovative—they’re better business models. They boost margins by aligning costs with actual usage, deliver clearer and more actionable metrics, and reflect the true value provided by AI-powered solutions, which are inherently tied to outcomes rather than seats. The result: higher customer satisfaction, stronger retention, and faster growth.

But making this shift isn’t easy. Legacy billing systems weren’t built for the demands of today’s pricing: real-time data processing, intricate pricing structures, and the ability to support various cost management requirements across self-serve and enterprise customers. Businesses relying on these outdated tools risk falling behind as their competitors move toward more flexible and efficient solutions.

Metronome’s 2.0 platform helps businesses adopt flexible and scalable billing systems, enabling them to experiment, adapt, and grow faster while delivering pricing strategies that match customer expectations.

From back office to growth engine: Billing redefined

Adopting usage-based pricing is transformative, but it comes with significant operational and technical hurdles—not to mention financial uncertainty. Across the billing lifecycle, companies face challenges at every step: launching new pricing models, integrating billing seamlessly into the product experience, acting on real-time usage data, and iterating to refine pricing strategies.

More pricing levers, more complexity

Companies transitioning to a usage-based model often underestimate the complexity of pricing. Businesses must define metrics that accurately capture customer value, adjust volume tiers with varied usage patterns, and navigate nuanced challenges like prepaid and postpaid models. Successfully launching these models often requires pilots or phased rollouts to validate strategies and minimize disruption to customers.

Launch faster with Metronome

‍Metronome simplifies the launch of usage-based and hybrid pricing models. Flexible pricing metrics decouple pricing logic from event ingestion, enabling businesses to design and update pricing models without reworking their data pipelines. Metronome’s dimensional pricing structure lets companies tailor rates, discounts, and configurations for specific segments and use cases, ensuring pricing aligns with customer needs. The platform supports both product-led growth with standardized plans and sales-led growth (SLG) with configurable enterprise contracts. Businesses can also set up trials, discounts, and free credits linked to new products, promoting adoption without compromising revenue.

Pricing on usage creates spend uncertainty

Variable pricing models can confuse customers accustomed to predictable costs. Without clear, real-time visibility into how usage translates to spend, customers may feel uncertain and lose trust in the pricing structure.

Connect billing to product experience
Metronome embeds billing into the product experience, giving customers real-time dashboards that provide insights into their usage and costs. Spend controls let businesses set alerts or trigger automated actions when usage thresholds are reached, helping customers avoid unexpected charges. Flexible billing dashboard allows customers to drill down into costs by any dimension, ensuring full transparency.

Every team is a growth team

Usage-based pricing requires a cultural shift where every team—from product to sales to finance—focuses on driving value and product adoption. Teams need real-time, actionable data to identify opportunities and respond to challenges.

Act on real-time data with Metronome.
Metronome provides granular billing data tailored to every team’s needs:

• Product teams can identify high-value features, resolve bottlenecks, and forecast revenue for future features.
• Sales teams can identify upsell opportunities and churn risks with alerts triggered by product usage.
• Engineering teams can track feature-level revenue and correlate it with costs to analyze margins.
• Finance teams can streamline revenue recognition and forecast segmented revenue by cohort or feature.

Launching is hard—updating is even harder

In a usage-based model, every product feature must tie directly to pricing that reflects its value and drives usage. Unlike seat-based pricing, where charges are decoupled from product interactions, usage-based pricing requires constant iteration to stay aligned with customer usage and value.

Legacy systems make pricing updates slow, manual, and error-prone, often leading to SKU proliferation and coordination challenges across teams. Without the ability to iterate quickly, businesses risk misaligned pricing, frustrated customers, and a loss of competitive advantage.

Iterate without friction
Metronome’s declarative and modular pricing model enables teams to easily define and update pricing, automating tracking, coordination, and deployment across customer cohorts.

• Schedule updates for specific cohorts, ensuring smooth rollouts
• Apply global updates while preserving custom discounts and contract terms
• Adjust individual customer contracts throughout their lifecycle, with changes automatically reflected in consolidated invoices

Metronome ensures pricing evolves alongside the product, helping businesses deliver fair value to customers and remain competitive.
