Unified API

Unified.to operates a unified API and Model Context Protocol (MCP) platform that lets B2B SaaS applications and AI agents read from and write to their customers' third-party software systems through a single normalized interface. The platform advertises 948 integration sources across 35 API categories, including CRM, ATS, HRIS, accounting, messaging, e-commerce, payments, file storage and knowledge management. Alongside unified endpoints and data models, it unifies authorization, webhooks and permission scopes, and supplies embeddable front-end components for account authorization, single sign-on with OAuth 2 OpenID across 60+ identity providers, and an integrations directory.

The architecture is real-time pass-through: each request is executed live against the source API and normalized in memory, rather than served from a scheduled sync or cache. End-customer payload data is not stored; traffic is stateless and regionalized across US, EU and AU. The product supports native webhooks where a source provides them and virtual webhooks, built on a scheduling layer, where it does not, plus custom fields, read/write on custom objects such as Salesforce, and raw payload passthrough for integration-specific fields. The company positions the platform for AI use cases, feeding real-time data into embedding and RAG pipelines and letting agents perform write actions through unified MCP endpoints.

Founding story

The company was co-founded by Roy Pereira, a four-time founder with three acquisitions who serves as CEO, and Alexey Adamsky, a two-time founder with two acquisitions who serves as CTO. Pereira has said the founders experienced the cost of building and maintaining API integrations at their previous companies and built Unified.to as a universal API translator in response.

Business model

Software-as-a-service integration infrastructure sold to software companies, delivered via APIs, SDKs in 7+ languages and embeddable UI components, with a free 30-day trial and a startup tier for early-stage companies.

Usage-based pricing that scales with API request volume rather than the number of customers or linked accounts, positioned as portable because customers own their own integration credentials.

Traction

By October 2024, roughly a year after launch, the platform supported 16 verticals and a small team had shipped more than 200 API integrations; the company's site later cites 948 integration sources across 35 categories. A referenced customer outcome is Toronto-based HR software company Humi, which added 25 HRIS integrations in one month and was reported to have saved $1 million in integration development costs. The real-time unified API was named Best Business Software API at the 2026 API Awards.

Latest developments

The company markets a unified MCP product with write endpoints for AI agents alongside its unified API, reports 948 integrations across 35 categories, and announced that its real-time unified API won Best Business Software API at the 2026 API Awards. Its public SDK and front-end component repositories were updated through September 2026.
