Merge is a unified API platform designed to simplify how B2B software companies build and maintain integrations and power AI agents. It enables businesses to connect once and access hundreds of third-party systems, such as HRIS, accounting, ATS, ticketing, CRM, and file storage, eliminating the need to build separate connectors for each vendor. Merge manages the full integration lifecycle, including authentication, security, monitoring, and ongoing maintenance, addressing the common pain point of expensive, time-consuming upkeep of integrations.
Key Features
Merge consists of three core products: Merge Unified, Merge Agent Handler, and Merge Gateway. Merge Unified offers a single API enabling sync of customer-facing integrations across dozens of categories, for both reading and writing data, with support for normalized data and field-level controls. Use cases span from onboarding or offboarding employees, headcount planning, and payroll analysis to CRM use cases like sales rep performance and opportunity generation.
Merge Agent Handler empowers AI agents with secure access to third-party tools, managing credentials, permissions, and providing full audit trails for every tool call. Merge Gateway balances cost, reliability, and performance across large-language model providers and offers spend visibility alongside zero lock-in. Merge also emphasizes observability with dashboards for integration monitoring, error detection, rate limits, webhooks, and logs.
Security features include SOC 2 compliance, SAML-based single sign-on, dedicated account managers, shared Slack channels, field-level data scopes, and single-tenant or self-hosted options for enterprises.
Pricing
Merge Unified is available under tiered plans. The Launch plan allows up to three production Linked Accounts for free; for up to ten Linked Accounts it costs $650 per month. Additional Linked Accounts beyond that are billed at $65 per account.
Professional and Enterprise plans are contract-based and include more advanced features such as custom sync frequencies, field-level scopes, audit trails, uptime SLAs, and greater customization and support.
Agent Handler has a Free plan offering 2,000 monthly credits, and a Pro plan at $1,000 per month with 25,000 credits, unlimited registered users, tool packs, and email support. An Enterprise tier is also available for larger organizations needing custom connectors, deployment options, and dedicated SLAs.
Who is it for?
Merge is suited to product and engineering teams at SaaS companies, from startups to enterprises, that need to embed third-party integrations or enable their AI agents to act on external systems without maintaining each connection themselves. Companies that rely on data from HR, payroll, accounting, CRM, or ATS tools to enable features like employee onboarding, compliance, workflow automation, or AI-driven insights could benefit.
Businesses dealing with high integration maintenance costs, frequent connector breakdowns, or slow time to market for new integrations will find value in Merge's unified approach. Decision-makers in product, engineering, operations, and security will especially care about its auditability, observability, and security controls.
Final thoughts
Merge provides a robust platform for reducing the engineering burden of integrations and enabling richer AI agent capabilities without sacrificing security and reliability. For businesses looking to accelerate integration development, maintain data consistency, and scale efficiently across multiple third-party systems, Merge offers a compelling solution.
Its tiered pricing and contract-based Enterprise options ensure that organizations can align spending to scale and complexity. Nonetheless, teams should carefully assess their volume of Linked Accounts, expected data types, and required security and compliance features before choosing a plan.
