What JustPaid does
JustPaid (legal entity Loopfour Inc., Delaware C Corporation, founded November 2022) is an AI-powered revenue operations platform that automates the B2B billing lifecycle from contract extraction through collections. Headquartered in Mountain View, California, and backed by Y Combinator's W23 batch with approximately $5.9M raised across seed-stage rounds, the company sells to AI startups, technical founders, mid-market firms, and enterprises across healthcare, finance, accounting, real estate, and creator monetization verticals, with SOC 2 Type 2, HIPAA, and GDPR certifications enabling regulated-industry deployments. The platform reports 8.5K+ customers managed, 16K+ invoices processed, and $77M+ in payment volume flowing through it.
The product architecture is a modular core platform that unifies contract ingestion (AI extraction of billing terms from DocuSign and similar sources), invoice generation, multi-currency billing with real-time FX, usage-based metering via API, payment reconciliation, and AI-driven accounts receivable with adaptive dunning. Add-on modules include Contract & Billing AI, Reminder AI, Usage-Based Billing, Customer Invoicing, Revenue Insights, Upsells & Renewals, a Pricing Page Builder for self-serve checkout, and an AI Copilot Chat that lets users query billing data in natural language. In April 2026 the company launched Loopfour.ai — a distinct sub-brand offering a workflow-and-integration platform for moving financial data across CRMs, billing systems, accounting platforms, and data warehouses — and AI Gilfoyle, an autonomous multi-agent engineering system that internally builds product features. JustPaid integrates natively with Stripe, QuickBooks, Xero, NetSuite, Sage Intacct, Salesforce, HubSpot, Attio, Plaid, Avalara, TaxJar, PandaDoc, Dropbox Sign, Slack, DocuSign, and other systems.
Commercially the company operates a hybrid model combining product-led growth self-serve checkout with sales-assisted enterprise motion, charging subscription and/or usage-based pricing on monthly cadences without publicly disclosed tiers. GTM signals include 'Talk to Founder' and 'Book a Demo' CTAs for enterprise, an API-first developer experience, and a partner program spanning implementation, technology, and channel partners. Named case-study customers include OTO Health (50+ audiology practices across five countries), FlowHealth (AI contract-to-cash across medical practices), Veryfi (99.9% billing accuracy on complex contracts), and Competera (multicurrency invoicing for retail AI). Current leadership comprises Daniel Kivatinos (CEO, prior DrChrono), Vinay Ramesh (CTO), and Anelya Grant (COO), with Harshith Vaddiparthy added as AI Product Engineer and Growth Strategist.

Broad incumbents
- Stripe Billing: Stripe's native billing module handles subscription, usage-based, and recurring billing for millions of merchants. Overlaps significantly with JustPaid's invoicing, subscription, and usage-based billing features but bundled within the broader Stripe payments ecosystem.

- Pleo: European corporate cards and bill pay/spend management platform. Adjacent competitor on automated B2B payments, invoice capture, and finance stack integration — comparable SMB/finance-team motion.
- Sage Intacct: Mid-market cloud ERP/accounting system with AR, billing, and revenue recognition modules. JustPaid integrates with Sage Intacct and competes indirectly for the same finance-team buyer, especially in healthcare and SaaS verticals.
Emerging players
- Stigg: API-first usage-based pricing and billing platform for SaaS. Comparable on the usage-based billing and pricing experimentation layer that JustPaid offers, but more narrowly focused on pricing rather than full AR automation.

- Togai: Usage-based pricing and billing infrastructure for SaaS and API companies. Direct comparable on consumption-based billing, entitlement management, and the developer-first go-to-market motion.
