Merge Tech Stack

API platform for unified integrations and AI agent tooling

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

Merge operates a two-sided integration platform: Merge Unified handles third-party API connectivity at scale, while Merge Agent Handler secures AI agents' access to external tools. The tech stack reflects a mature, distributed system (PostgreSQL, Redshift, Kinesis, Kubernetes, Elasticsearch) built for reliability at enterprise scale. Active hiring is concentrated in engineering and sales with seniority skewed senior, while projects signal aggressive growth — sales motion scaling, platform redesign, and AI-native product expansion are all underway simultaneously, suggesting execution pressure on a lean team.

About Merge

Merge provides integration infrastructure for B2B SaaS companies and enterprises. The platform abstracts away authentication, monitoring, and lifecycle management for hundreds of third-party integrations, sold as a single API. A second product, Merge Agent Handler, extends this to AI agents, enabling secure access to thousands of third-party services. The company was founded in 2020 and operates across San Francisco, New York, and Berlin. Customers use Merge to reduce churn, unblock sales cycles, and avoid building integration plumbing in-house.
