Founder story
Founded in 2020 by Gil Feig and Shensi Ding in San Francisco. Both founders were early employees at high-growth startups and saw that building integrations was the most painful, non-core part of the engineering roadmap. They built Merge to turn 'integrations' into a solved problem for every software team.

Finch: Focused almost exclusively on Payroll/HR; Merge offers a wider range of 'Unified' categories like CRM and Ticketing.
Merge is the best choice for SaaS companies that want to build a truly 'integrated' product without the engineering debt.
