What Paygent does

Paygent is a SaaS-based monetization and cost-tracking platform purpose-built for AI agent companies. Its core product is an event-driven billing infrastructure that defines AI 'Agents' (e.g., chatbots, content generators, voice assistants) and 'Indicators' (discrete billable actions such as messages sent or meetings booked), aggregates raw usage across LLM, STT, TTS, and other AI providers in real time, and produces itemized invoices under multiple pricing models. Native metering supports Sum, Count, Max, Unique, Latest, and Custom aggregations across tokens, hours, bytes, and peak concurrency, and a credit/wallet subsystem handles prepaid balances, rollover, and overage. The platform exposes Python, Node.js, and Go SDKs, pre-built hooks into LiveKit and Vapi, auto-patching for OpenAI/Anthropic/Gemini calls, a REST voice API, and a Stripe payment-link integration for invoice collection. Pricing tiers run from a Free plan (100K events/month) through Starter ($399/month, 10M events) and Growth ($799/month, 25M events) to custom Enterprise contracts, with usage-based, outcome-based, and seat-based pricing mechanics documented for enterprise deals. The company is privately held, based in San Francisco, employs 1–10 people, is backed by Antler, and holds SOC 2 Type II and GDPR compliance posture. Named customers include Prodloop, Processed AI, Grexa, Aguken, Zotel.AI, Revrag, Phonetiq, and Callintell — all early-stage AI startups using Paygent for usage tracking, profitability visibility, and billing automation.

Revenue model

1. Platform Subscription Fees: Tiered subscription model (Free, Starter $399/mo, Growth $799/mo, Enterprise custom) providing platform access, event limits, data retention, and support levels. Revenue scales with customer growth stage.
2. Activity-Based Usage Billing: Charging customers based on AI activities performed - tokens used, API calls made, or actions taken. Customers pay per event or aggregated metric (e.g., $0.50/hr GPU compute). Revenue scales with AI usage.
3. Outcome-Based Pricing: Charging based on successful outcomes or results achieved (e.g., $50 per meeting booked, $5 per ticket resolved). Aligns pricing with customer value delivered rather than activities performed.
4. Seat-Based Pricing: Per-user/per-seat charges for team members accessing AI platforms, with volume discounts (5% at 10-19 seats, 10% at 20-49 seats, 20% at 50+ seats). Revenue scales with team growth.
5. Credit/Wallet Prepaid Model: Sell prepaid usage in custom credit currencies. Customers hold wallets per credit type, usage debits automatically at billing time. Supports rollover credits and overage credit lines.
6. Setup/Onboarding Fees: One-time fees for initial integration, setup, training, or onboarding work (e.g., $2,500 for small business, $5,000 for mid-market, $15,000 for enterprise). Common for enterprise onboarding.
