What Orb does
Orb, Inc. is a San Francisco-based usage-based billing infrastructure company founded in 2021 by former Asana engineers Alvaro Morales (CEO) and Kshitij Grover (CTO). The company's core product is a billing platform built on a raw event architecture: every usage event is ingested and stored in full, enabling the engine to recalculate invoices, backdate pricing changes, and run revenue simulations from historical data without re-ingestion or engineering rework — a design Orb explicitly contrasts with streaming-aggregator competitors. The platform is exposed via a versioned Orb API with Python, Node, and Go SDKs, webhook-driven extensibility (HMAC SHA-256 signed, at-least-once delivery), and native integrations with Stripe (including Stripe Link), Salesforce, NetSuite, QuickBooks, Bill.com, Adyen, Slack, cloud marketplaces, and tax providers. The application is hosted on AWS within a VPC, protected by Cloudflare, AWS WAF, and GuardDuty, and is SOC-2 Type II certified with annual third-party penetration testing.
Orb monetizes through a hybrid of subscription fees and on-demand usage-based charges, both negotiated via quote-based enterprise contracts (no public list pricing), supported by a 30-day free trial and a self-serve PLG motion alongside a primary sales-led motion targeting enterprise SaaS and AI customers. Named customers span developer infrastructure, databases, AI, and analytics — Vercel, Glean, Replit, Supabase, LaunchDarkly, Fal, Neo4j, Redis, WRITER, Airbyte, Dune, and Materialize — with segments explicitly including Agentic AI/GenAI, cloud infrastructure, and sales-led growth companies in addition to core SaaS. Public operational metrics include 99.96% API uptime over a 90-day rolling window.
The company raised approximately $44 million in total funding across seed, Series A ($14M, March 2023), and Series B ($25M, September 2024), and in June 2026 entered a definitive agreement to be acquired by Adyen N.V. for $335 million in cash via a reverse triangular merger, with the co-founders reinvesting in newly issued Adyen shares. The transaction, expected to close July 1, 2026 pending regulatory approvals, will position Orb as an indirect wholly-owned subsidiary of Adyen operating under an incubator model, combining Orb's billing engine with Adyen's payments infrastructure and Dynamic Identification fraud system to serve global merchants.

Revenue model
- SaaS subscription fees: Customer pays subscription fees per the executed Order Form for access to the Orb Platform, Orb API, and Documentation; auto-renews unless cancelled with 60 days' notice, and Orb may revise fees at renewal.
- On-demand usage-based charges: Additional charges calculated per the Order Form formula and invoiced in arrears monthly, typically tied to customer usage of Orb (e.g., number of billable events or seats); Orb's own customers are billed on this metered basis.
- Free trial and beta access: 30-day free trial and beta features are offered at no charge as a customer acquisition lever; these are provided AS IS without warranty and Orb disclaims all liability for trial/beta use up to a $100 cap.

Orb partnerships and signals
Strategic signalPartnerships
Eight partnerships are on record, tiered core.
- StripecoreStripe is Orb's primary payment processor for automated invoice collection. Orb offers Stripe-based recurring payment methods including Stripe Link, sends invoice.payment_failed and invoice.payment_succeeded webhooks to surface failed/successful payments, and Orb support documentation describes migrating from Stripe subscription billing to Orb billing with Stripe payment processing.
- SalesforcecoreSalesforce is a first-class integration target for Orb: Orb's 'Finance workflows' product is described as connecting usage data to contracts in the CRM to bill seamlessly, and Orb support documentation includes dedicated guidance and Loom walkthroughs for syncing Orb data into Salesforce and pushing Orb events into SFDC record-triggered flows.
- QuickBookscoreQuickBooks is one of Orb's supported accounting sync integrations, with Orb issuing dedicated customer, invoice, subscription, transaction, credit note, and credit block accounting_sync_succeeded/accounting_sync_failed webhooks.
- NetSuitecoreNetSuite is the second accounting integration supported by Orb, alongside QuickBooks, with the same accounting_sync webhooks for customers, invoices, subscriptions, transactions, credit notes, and credit blocks.
- AdyencoreIn addition to the acquisition, Adyen is supported as a payment integration in Orb's invoicing/exports documentation. Post-acquisition (expected July 1, 2026) this relationship will become deeper as Orb's billing engine is combined with Adyen's payments infrastructure.
- Amazon Web Services (AWS)coreAWS is Orb's primary cloud infrastructure provider: Orb uses a virtual private cloud (VPC) for resource isolation, AWS WAF, AWS Security Groups, AWS GuardDuty, and AWS Config for change tracking; data is encrypted at rest across S3, volumes, and production datastores. Orb does not store customer data on-site.
- CloudflarecoreCloudflare is used by Orb on select endpoints as a proxy to prevent denial-of-service attacks, providing an additional network protection layer in front of Orb's APIs.
- GitHubcoreOrb's core application source code is hosted on GitHub (a SOC-2 compliant organization) under a private repository protected by multi-factor authentication, used for change management, dependency monitoring, and CI/CD security testing.

Orb competitors and assessment
Company assessmentDirect peers
- Metronome: Metronome is a usage-based billing platform for SaaS and AI companies, the closest direct competitor to Orb in feature set (real-time usage metering, hybrid pricing, developer-first API, finance workflows) and target customer (high-growth SaaS and AI-native companies).
- Chargebee: Chargebee is a subscription billing and revenue management platform serving SaaS and subscription businesses. It overlaps with Orb on subscription and usage-based billing, recurring invoicing, and revenue recognition, though it is more PLG-oriented and broader in scope than Orb's usage-based focus.
- Recurly: Recurly is a subscription billing and management platform for SaaS, digital media, and consumer subscription businesses. It is a direct peer in subscription and recurring billing, with growing usage-based capabilities that overlap Orb's feature set.
- Maxio: Maxio (combining SaaSOptics for billing/financial operations and Chargify for subscription management) is a direct peer in subscription billing and SaaS financial operations, targeting a similar mid-market and growth-stage SaaS customer base as Orb.
- Paddle: Paddle is a merchant-of-record billing and payments platform for SaaS. It competes with Orb on subscription and usage-based billing for SaaS companies, with a distinctive tax and compliance bundle that overlaps Orb's invoicing and revrec functionality.
Broad incumbents
- Stripe Billing: Stripe Billing is the incumbent usage-based and subscription billing offering from Stripe, bundled into the dominant payments platform. It overlaps directly with Orb on usage-based billing but competes from a much broader distribution and capital base, not a billing-only focus.
- Zuora: Zuora is an enterprise subscription billing and revenue management incumbent. It overlaps with Orb on usage-based and hybrid pricing, revrec, and finance workflows, but is positioned for large enterprises with a heavier, more generalist footprint than Orb's developer-first focus.
- Salesforce (Revenue Cloud / Salesforce Billing): Salesforce Revenue Cloud and Salesforce Billing are the billing capabilities of the broader Salesforce CRM and revenue platform. They overlap with Orb on contract-to-bill workflows and CRM-integrated revrec, and Salesforce is also a first-class integration partner for Orb, positioning it as both a partial competitor and a channel dependency.
Emerging players
- Lago: Lago is an open-source usage-based billing platform, an emerging peer targeting the same SaaS and AI developer audience as Orb. It overlaps on usage metering and pricing models and is gaining traction as an open-source alternative in Orb's category.
- Stigg: Stigg is a SaaS pricing and packaging platform with usage-based metering capabilities. It is an emerging peer addressing a portion of Orb's surface area (pricing iteration, metering) for SaaS companies, often as a complement to billing systems rather than a full replacement.
