Orb (Adyen)

Orb is a usage-based billing platform sold to AI and SaaS companies. Adyen announced its purchase on June 11, 2026, for $335M in cash and closed on July 1, 2026. Orb runs inside Adyen on an “incubator model,” and the founders reinvested proceeds into Adyen shares (Adyen PR, Orb blog). Alvaro Morales (CEO) and Kshitij Grover (CTO), formerly at Asana, founded it in San Francisco in 2021.

Pre-exit funding was $44M, including a $25M Series B in September 2024. Headcount was about 93 in May 2026. Orb does not disclose a customer count and says it “tripled since the start of 2024” (vendor claim). Bottom line: a strong billing product that has become a processor’s billing arm, with reach set by Adyen’s choices. As of October 14, 2026, the core design is unchanged from the July close: query-based billing over immutable events, immutable plan versions with migrations, invoice changes applied through an InvoiceDiff in one transaction, dry runs and pending changes, a prepaid credit ledger separate from the customer balance, and alerts on a second pipeline that never feeds invoices (Orb docs).

What does it sell?

Orb markets six pieces: usage-based billing (metering, rating and invoicing for AI and token pricing at scale), pricing design and simulation, invoicing with a payment portal, dunning with retry workflows for card and ACH, ASC 606 revenue recognition with a NetSuite sync, and a developer platform with an API, SDKs in Python, Node, Ruby and Go, and migration guides from Stripe Billing, Metronome and Chargebee. The target is AI companies first, then SaaS, cloud infrastructure and enterprise software. Geography is not stated.

All 12 case studies are software or AI companies, including Vercel, Replit and Perplexity. Pricing is custom only across three tiers (Core, Advanced, Enterprise), with no published numbers and no trial. The fee is metered on billings issued through Orb plus events ingested, with a platform fee on upper tiers. After the close, Orb says customers keep their preferred processor (vendor claim).

What does it ship for AI agents?

Nothing shipped. Orb publishes AI monetization content on token and agent pricing, and Morales describes a “self-driving” revenue infrastructure vision. This review rates that as an announced vision with no shipped in-product AI (High). Adyen shipped an “Agentic” API suite five days after the announcement, with no stated link to Orb. Cross-border and multi-currency money movement is Adyen’s stated goal for Orb, with nothing shipped (Speculative).

What does a buyer need to check?

• Reviews: G2 5.0 on about four reviews. No Capterra listing. No analyst coverage.
• Top complaint: “still a startup,” feature gaps, and QuickBooks connection friction, from a tiny sample.
• Implementation: a 30-minute quickstart claim for the API (vendor claim).
• Pricing: entirely behind “Contact Sales,” with a percent-of-billings component.
• Scope limits: no cash application, collections workflow, credit, disputes or e-invoicing evidence, and no customers outside software.
• Ownership stage: Adyen subsidiary since July 1, 2026, run as an incubator.

What to watch

• An Adyen “Agentic” API tied to Orb billing data, in Adyen developer docs and press.
• The first non-software Orb customer, in Orb case studies or Adyen earnings commentary.
• Weaker multi-processor language, on the Orb site, docs and pricing page.
• Logos moving to Metronome or Lago, in rival case studies and on LinkedIn.
• A cash application or collections release, in the Orb changelog and job posts.
