# Metronome

*/Startups/Metronome*

## Startup Overview

This billing engine ingests raw product events to calculate consumption-based pricing in real time. Software companies operating on usage-based models use the system to translate high-volume product activity, such as API calls or compute minutes, directly into accurate invoices.

Engineering teams traditionally consume massive resources building custom data pipelines to aggregate usage metrics for finance. This platform removes that burden by accepting granular, unaggregated event streams straight from the application infrastructure. It processes these events immediately to maintain an auditable, real-time ledger of customer consumption.

Incumbent platforms like Stripe Billing and Chargebee tightly couple invoice calculation to their own payment processing logic. This solution wins by remaining completely decoupled from the payment layer, operating as a developer-native metering engine. It replaces fragile in-house pipelines with a dedicated calculation layer that feeds finalized billing data to any downstream financial system.

## Startup Offer

**Proof**:
- Targeting high-volume API companies seeking to eliminate manual end-of-month spreadsheet reconciliation
- Aimed at AI infrastructure providers needing to bill instantly for per-token compute streams
- Designed to maintain zero-loss event pipelines even during unexpected traffic spikes or client retries
**Tiers**:
- Name: Growth · Price: ~$0.002–$0.005 per ingested event · Inclusions: Up to 5 million raw product events per month, 1-year data retention, and standard API access for early-stage usage-based products
- Name: Scale · Price: ~$1k–$2k/mo base + ~$0.0005–$0.001 per event · Inclusions: Up to 50 million events per month, advanced deduplication, native CRM syncing, and priority support SLAs for mid-market platforms
- Name: Enterprise · Price: Custom: ~$40k–$80k/yr · Inclusions: Volume discounts beyond 50 million events, dedicated integration engineering, custom data retention rules, and isolated infrastructure
**Guarantee**: If event ingestion or calculation logic drops or miscounts a single valid payload, we refund the processing tier fees for that billing cycle and deliver a full root-cause analysis within 24 hours.
**Business Function**: ProvideService
**Objection Handlers**:
- Does this force us to switch payment processors? No. It is designed to run completely decoupled from payment gateways; it calculates the totals and passes the final amount to Stripe, Adyen, or your current processor.
- What happens if our servers send duplicate events? The ingestion API requires idempotency keys and enforces strict automatic deduplication to ensure buyers are never double-billed.
- Will integrating this slow down our application? No. The platform is designed for asynchronous event tracking, keeping your core product performance strictly isolated from the billing pipeline.

## Startup Proof Points

_Illustrative — target and order-of-magnitude estimate figures, not an achieved track record (this Thing is concept-stage)._

**Pilot Goals**:
- 30-day shadow billing pilot: Process up to 5 million raw product events in parallel with the client's existing system to prove zero-loss event pipeline reliability.
- 14-day API load-test pilot: Simulate extreme traffic spikes and client retries to validate that the deduplication engine catches every duplicate without slowing down the core application.
**Target Metrics**:
- Target: 100% capture rate of raw product events during unexpected traffic spikes
- Aim: 0 manual billing reconciliation hours required at the end of the monthly billing cycle
- Target: 100% successful deduplication rate for retried or duplicate incoming event payloads
- Aim: Sub-50ms latency impact for asynchronous event ingestion to ensure core product isolation
**Target Case Studies**:
- AI Infrastructure Provider: Transitioning a high-compute startup from flat-rate subscriptions to dynamic per-token billing streams without dropping a single payload.
- High-Volume API Company: Moving a mid-market data provider from manual end-of-month spreadsheet reconciliation to automated, synchronized invoice generation via Stripe.
- B2B SaaS Platform: Implementing complex usage tiers and overage limits securely by utilizing idempotency keys to completely eliminate duplicate billing errors.
**Testimonial Targets**:
- VP of Engineering: Expressing relief that integrating the asynchronous event tracking keeps core product performance completely isolated from the billing pipeline.
- Head of Finance: Communicating absolute trust in the invoice totals because the strict automatic deduplication completely eliminates customer double-billing disputes.
- AI Startup Founder: Highlighting the ease of launching per-token compute pricing while maintaining their existing payment processor relationships.
