Revenue model
- Usage-based subscription (data-delivered pricing): Primary monetization is recurring subscription billed on usage: the amount of data processed and delivered through Read, Write, Subscribe, and Proxy Actions, measured in gigabytes. Pricing tiers (Launch free, Catalyst $999/mo, Accelerate custom annual, Enterprise custom) include monthly GB allowances with published overage rates; no charge for connections, customers, integrations built, or token management.
- Freemium / free tier acquisition: Launch tier is permanently free with a one-time 2 GB data-delivered credit, up to 5 customers in production, unlimited integrations and connectors — designed to drive PLG adoption and land-and-expand into paid Catalyst ($999/mo) and Accelerate/Enterprise contracts.
- Enterprise / white-glove professional services: Enterprise tier includes white-glove migration, dedicated integration product team, marketplace listings assistance, on-prem/VPC/BYOC deployment options, and high-availability SLAs — adding professional-services and managed-services revenue alongside the subscription.
Pricing tiers
| Model | Billing | Price |
|---|---|---|
| Freemium | Pay-as-you-go | Launch — free forever, 2 GB one-time data credit, up to 5 production customers |
| Subscription | Monthly | Catalyst — $999/month for up to 2 GB data delivered/month |
| Subscription | Annual | Accelerate — Custom pricing billed annually for mid-market and enterprise customers |

Ampersand product offering
Product offeringCore offering
Ampersand is a developer platform for native, bi-directional B2B SaaS product integrations. Product engineering teams declare integrations in a YAML file (amp.yaml) versioned in their Git repository and ship customer-configurable CRM/ERP/HRIS/marketing/sales integrations in days rather than months. The platform bundles managed OAuth, sub-second event-driven webhook delivery, custom object and per-customer field mapping, and an open-source AI SDK and MCP server so LLM-based agents can read and write to enterprise systems of record.
Product overview
Ampersand is a single developer platform — branded as 'Onset Labs, Inc.' (Ampersand®) — for building native product integrations, distributed as a unified offering rather than separate products. The core platform, the open-source Connectors library, the Embeddable UI Components, the AI SDK and MCP server, and the amp.yaml declarative framework are sold together under a four-tier pricing model (Launch, Catalyst, Accelerate, Enterprise) on withampersand.com, with the AI SDK, MCP server, custom object/field support, and unlimited integrations bundled into every tier.

Ampersand competitors and assessment
Company assessmentDirect peers
- Merge: Unified API platform offering pre-built integrations across HR, payroll, CRM, accounting, and ticketing for B2B SaaS. Most direct peer in the developer-led unified API category; competes on similar buyer (B2B SaaS product engineers) and similar horizontal integrations, though Merge emphasizes breadth of categories over depth of any single connector.
- Paragon: Developer-first integration platform for SaaS products, offering pre-built connectors, managed OAuth, and embedded workflows. Closely comparable on product (user-facing SaaS integrations), buyer (product engineers), and Go-to-market (PLG plus enterprise sales); both also target AI-agent use cases and hold customer OAuth tokens.
- Nango: Open-source developer infrastructure for product integrations, with managed OAuth, sync engine, and 250+ API connectors. Most direct peer on developer-first positioning and open-source connector library; explicitly named as a competitor on Ampersand's comparison pages and a reference point for the 'polling vs real-time' debate.
- Prismatic: Embedded iPaaS purpose-built for B2B SaaS vendors building customer-facing integrations. Comparable on product (user-facing integrations for SaaS) and target persona (product engineers at SaaS companies); Hatch migrated from Prismatic to Ampersand, making it a directly contested incumbent in embedded integration deals.
- Tray.ai: General-purpose iPaaS with a strong focus on customer-facing integrations for SaaS products. Comparable on integration platform category and B2B SaaS buyer; positions at a higher abstraction layer than Ampersand's YAML/declarative approach and is listed as a named competitor on Ampersand's comparison pages.
- Unified.to: Unified API platform targeting B2B SaaS product teams with embedded integrations across CRM, accounting, HRIS, and marketing. Comparable on product (embedded SaaS integrations) and target market (product engineers); a newer entrant with thinner custom-object depth than Ampersand but similar horizontal breadth.
- Apideck: Unified API provider for SaaS products, offering pre-built integrations, managed OAuth, and embedded UI components. Comparable on horizontal unified-API positioning and B2B SaaS target market, with a similar PLG plus enterprise hybrid go-to-market motion.
Emerging players
- Composio: Developer infrastructure for AI agents to integrate with external tools and SaaS APIs, with an MCP server and large connector catalog. Comparable on the AI-agent integration wedge that Ampersand is targeting with its AI SDK and Docs MCP; positioned for AI-native workloads rather than general-purpose SaaS product integrations.
- HotGlue: Lightweight ETL/data integration platform for SaaS products, focused on embedded customer-facing data pipelines. Comparable on developer-led integration infrastructure and the B2B SaaS buyer, but more skewed toward analytics/ELT workloads than Ampersand's CRM/ERP horizontal.
Broad incumbents
- Workato: Enterprise iPaaS leader with a broad recipe-based automation platform and a deeper enterprise footprint and ARR base than Ampersand. Not a direct developer-first competitor, but the established incumbent that Ampersand explicitly positions against on its comparison pages for embedded and AI-agent integrations.
