Merge

Merge started in 2020 as a single unified API for HR/ATS integrations and expanded to CRM, accounting, ticketing, file storage, knowledge base, and chat — eight categories, one normalized schema ("Common Model") per category, per Merge's docs (docs.merge.dev/home, checked 28 August 2026). As of August 2026 the vendor's docs claim 260+ documented Unified API integrations. In 2025-26 Merge added two more products under the same account and security review: Agent Handler, which exposes 180+ third-party tool connectors to AI agents over MCP with per-end-user OAuth, tool-pack scoping, and an audit trail; and Gateway, which routes LLM calls across 270+ models from 20+ providers with fallback, spend budgets, and zero-data-retention options. All three share Merge's authentication flow ("Merge Link") and one vendor relationship — the pitch is that a team already vetted for Unified API can add agent tool-calling or LLM routing without a second procurement cycle.

Merge Unified (checked merge.dev/pricing/unified, 28 August 2026): Launch tier is free for the first 3 production linked accounts, then $650/month for up to 10 total, $65/linked account after that, with volume discounts available. Professional and Enterprise are both "contract-based pricing" — no published number, reached via demo. The compare table does disclose real technical deltas between tiers: rate limits are 100 req/min on Launch, 400/min on Professional, 600/min on Enterprise; sync frequency tops out at daily on Launch vs. customizable higher frequencies above it. Agent Handler (merge.dev/pricing/agent-handler) has a genuinely free tier (2,000 monthly credits, unlimited registered users and tool packs) then a $1,000/month Pro plan for 25,000 credits with overage billing, or — under a separate "Merge for Workforce" SKU aimed at IT/security teams — a flat $10 per user per month. Gateway (merge.dev/pricing/gateway) is pass-through LLM cost plus a 5% fee on the Pro plan, with $10/month in free credits and no published spending cap; Enterprise on all three products is quote-only. So roughly two-thirds of the pricing surface (every Enterprise tier, Unified Professional) is not a real number — plan on a sales call to price anything past prototype scale.

Merge (Merge API Inc.) was founded in June 2020 by Shensi Ding and Gil Feig. Confirmed funding history: a $4.5M round (May 2021), a $15M Series A led by an investor group in November 2021, and a $55M Series B led by Accel in October 2022 — TechCrunch reported total funding at $75M as of the Series B, and Merge disclosed 30x ARR growth in the prior 12 months and roughly 2,500 customers at that time (techcrunch.com/2022/10/24, checked 28 August 2026). No funding round has been publicly reported since October 2022 — nearly four years without a disclosed new raise for a company that has since roughly tripled its product surface. Third-party aggregator Sacra estimates 2023 revenue at $20M and a 2023 valuation of $317M (sacra.com/c/merge, checked 28 August 2026) — these are Sacra's own modeled estimates, not filed or vendor-disclosed figures, and should be read as directional only.

Merge's GitHub org (github.com/merge-api, checked 28 August 2026) hosts about 55 repos, most notably MIT-licensed client SDKs for Python, Node, Java, Go, and Ruby, plus React components for the Merge Link and Agent Handler Link auth flows. These are thin, actively maintained API clients — the Node client shows commits within the past week of this check — but they are not the product. Merge Unified, Agent Handler, and Gateway are all closed-source hosted services; nothing about the MIT license on the SDK repos extends to self-hosting or inspecting the actual integration/routing logic.

Merge's security page (merge.dev/security, checked 28 August 2026) states certifications in SOC 2 Type II, ISO 27001, HIPAA, GDPR, and CCPA, hosted on AWS with application-layer encryption of PII, a choice of US/EU/APAC multi-tenant or single-tenant hosting, and a public vulnerability disclosure program (security@merge.dev). A public Trust Center is linked (trust.merge.dev) alongside a Data Processing Agreement. These are vendor-stated certifications; we did not independently verify the underlying audit reports, which is normal — that verification typically happens under NDA during a security review, not from a public trust page.

Merge publishes a live status page (status.merge.dev) with per-component uptime (Unified API, Dashboard, Merge Link, sync engine, Agent Handler, docs) and incident history — the two most recent entries as of this check were a 1.5-hour docs outage (Aug 5, 2026, attributed to a downstream vendor) and a scheduled 46-minute maintenance window (Aug 4, 2026), both resolved with timestamped updates. The changelog (merge.dev/changelog) posts weekly, dated, per-product entries with specific before/after detail — e.g., an Outlook payload-size fix that cut a typical message from 57KB to 14KB — rather than vague "improvements and bug fixes." This is a materially more detailed changelog than most vendors in this space publish.

Merge has review pages on G2 (255 reviews across its listings, per G2's own site) and TrustRadius, but we could not read star ratings or review text from either. We are not repeating any rating or review count as fact until it can be read directly.

Merge's site names Perplexity Enterprise Pro, Mistral AI, Zoom, Ramp, Bill.com, Drata, Foxit, and Electric as customers, each with an attributed testimonial quote (e.g., Perplexity's Head of Enterprise Product on using Agent Handler to add data connectors; Zoom's Head of Engineering estimating Merge's integration-observability tooling would have taken 3 months to build in-house). These are vendor-published case studies and quotes attributed to named individuals at real companies, not independently corroborated by us, and should be read as customer testimonials rather than verified outcomes.
