Merge Tech Stack

API platform for product integrations and AI agent tooling

Software Development San Francisco, California 51–200 employees Founded 2020 Privately Held

Merge operates a dual-product platform: Merge Unified (a unified integration API) and Merge Agent Handler (secure tool access for LLMs). The stack is polyglot (Django + Python + Rails + Go + React + Vue) with heavy AWS/Kubernetes infrastructure, and hiring is engineering-led with mid- to senior-level engineers dominating headcount. Projects reveal a company simultaneously scaling integration breadth (7 categories, internal tooling for API provider management), building go-to-market (sales process redesign, customer success programs), and tackling talent acquisition friction in competitive West Coast markets.

About Merge

Merge provides integration infrastructure for B2B SaaS, enterprise software, and AI applications. The core offering allows businesses to embed hundreds of third-party integrations (across accounting, HRIS, ATS, ticketing, CRM, and project management verticals) without building custom connectors; a second product line exposes those integrations as tools for AI agents to call securely. Founded in 2020 and headquartered in San Francisco with offices in New York and Berlin, the company operates at 51–200 employees and is backed by $75 million in capital from Accel, NEA, and Addition. Revenue model and customer count are not disclosed, but the sales motion involves both developer-led and direct enterprise channels.
