## Summary

MIT PhD-founded enterprise AI platform for custom assistants and workflow automation; $16.6M YC-backed serving LifeMD and SmartAsset competing with Copilot Studio for low-code AI in regulated industries.

## Company Overview

StackAI is a Cambridge, Massachusetts-based enterprise AI platform enabling organizations to build custom AI assistants, automated workflows, and document processing pipelines through a low-code interface — without requiring deep machine learning engineering expertise. Founded in 2022 by MIT PhDs Anthony Rosinol and Bernardo Aceituno and backed by Y Combinator with $16.6 million total raised including a $16.1 million Series A led by Lobby Capital in October 2024, StackAI serves clients across healthcare, finance, and education including LifeMD, SmartAsset, and Circle Medical.

StackAI's platform provides a visual workflow builder where business teams connect LLM models (GPT-4, Claude, Llama), enterprise data sources (SharePoint, Salesforce, databases), and output actions to create AI assistants that answer domain-specific questions, automate document review, or trigger business processes. The enterprise security model (SOC 2, HIPAA compliance, private cloud deployment options) enables use in regulated industries like healthcare where document processing involves PHI. Pre-built templates for common use cases (contract review, customer support, employee onboarding) accelerate deployment.

In 2025, StackAI competes in the enterprise AI application platform and no-code AI builder market with Langchain (developer AI framework), Flowise (open-source LLM workflow builder), Microsoft Copilot Studio (enterprise AI builder within Microsoft 365), and Glean (enterprise AI search) for organizations building AI-powered knowledge work automation. The enterprise AI assistant market has fragmented into two segments: developer-focused frameworks (Langchain, LlamaIndex) requiring engineering resources, and low-code platforms (StackAI, Glean) targeting business teams who need AI automation without ML engineers. StackAI's MIT founder pedigree and Y Combinator backing attract technically-sophisticated enterprise customers. The 2025 strategy focuses on deepening healthcare and financial services vertical features, growing the enterprise contract base, and building the audit and explainability features regulated industries require.
