What Stack AI does
Stack AI is a no-code platform for building enterprise AI agents, intelligent forms, and document workflows. Users drag and drop components — LLMs, retrieval, OCR, conditional logic, integrations — onto a visual canvas to build chatbots, document extractors, smart intake forms, internal copilots, and multi-step automations, then deploy them as APIs, web apps, embedded widgets, or Slack bots. The platform replaces dozens of point tools (Typeform + Zapier + custom RAG + bespoke chatbots) with a single agent-building surface.
Stack AI's AI Forms product turns static intake (insurance claims, loan applications, vendor onboarding) into intelligent, conversational forms that auto-extract data from uploaded documents, validate entries with policy rules, and pipe outputs into downstream systems. Customers include government agencies, financial-services firms, insurers, and large education and healthcare buyers.
Who it's for
Stack AI targets operations, IT, and business-application teams at mid-market and enterprise organizations that want to deploy AI agents without writing code. Buyers are typically heads of automation, IT, or business-process modernization, with a heavy presence in finance, insurance, education, and government.
Pricing
Stack AI offers a free tier for prototyping, paid plans for teams, and enterprise plans with SSO, audit logs, and on-prem deployment.
Team & funding
Stack AI was founded in 2023 by Anthony Rosinol (CEO) and Bernardo Aceituno (CTO), both MIT-trained engineers. The company is a Y Combinator alum and has raised approximately $16.6M across 2 rounds, including a $16.1M Series A in October 2024 led by Lobby Capital with participation from Y Combinator and 8 other investors. By 2025 the platform supported workflows in finance, insurance, education, and government verticals.
Position vs competitors
Stack AI competes with Voiceflow, Botpress, n8n, Zapier AI, and Relevance AI in agent building, and with Typeform Formless and Jotform AI in intelligent forms. Its bet is that a single visual canvas spanning agents, forms, and workflows can replace stacks of point tools for enterprise automation.
