-- Stack AI, a company focused on building infrastructure for deploying AI agents in enterprise environments, has announced the successful close of a $16 million Series A funding round. This investment comes amid a surge in enterprise interest in AI, especially in tools that go beyond general-purpose chatbots to integrate deeply with internal systems and workflows.
According to recent estimates, over 82% of organizations worldwide are either actively using or evaluating artificial intelligence. This uptick, largely spurred by advances in large language models (LLMs), has set the stage for broader adoption of a new class of tools known as AI agents.
Why AI Agents, and Why Now?
The release of ChatGPT in 2022 brought AI into mainstream conversation, but many organizations have found that the true value of language models emerges only when they’re embedded into everyday tools and systems. This has led to the emergence of AI agents—software components that use LLMs in conjunction with data access and task automation capabilities.
Unlike standalone chatbots, AI agents can automate complex workflows such as scheduling, document retrieval, customer onboarding, claims processing, or auditing—tasks that often involve navigating multiple tools and data silos.
Stack AI’s platform enables companies to build and deploy these agents securely and at scale, with support for a wide array of enterprise systems including SharePoint, Snowflake, Salesforce, and Confluence. The platform is built with enterprise requirements in mind, offering on-premises and VPC (virtual-private cloud) deployment, as well as compliance with SOC 2 Type 2, HIPAA, and GDPR standards.
Growth Milestones Since Launch
Founded in April 2023, Stack AI has quickly developed both product maturity and market traction. The team, now composed of 16 members with backgrounds at MIT, Meta AI, NASA, BCG Gamma, and IBM, has supported adoption across a range of industries—from government agencies and hospitals to universities and Fortune 500 enterprises.
Key milestones include:
- Over 90,000 users signed up
- More than 100,000 AI agents deployed
- Support for 30+ LLM providers and 100+ data connectors
Real-World Use Cases
Stack AI’s technology is already in use for a variety of tasks. Organizations such as Nubank, LifeMD, a Top 5 U.S. Defense Agency, MIT Sloan, and SmartAsset have deployed agents to streamline and automate processes such as:
- Generating RFP responses using data from SharePoint
- Producing investment memos through automated web research
- Processing insurance claims via OCR and live search integration
- Training new hires using internal documentation
- Auditing sales calls for quality control
Funding and Future Roadmap
The $16 million Series A was led by Lobby VC and LifeX Ventures, with participation from Guillermo Rauch (CEO of Vercel) and Bob Van Luijt (CEO of Weaviate). Previous investors Gradient, Y Combinator, and Epakon Capital returned for this round, alongside Soma Capital, True Capital Ventures, and other angel investors.
With this funding, Stack AI plans to deepen its investment in three core areas:
- Simplicity – Continuing to reduce time-to-value for users and improving the usability of the platform for non-technical stakeholders.
- Capacity – Enhancing retrieval capabilities, extending LLM tool integrations, and ensuring flexible deployment options.
- Support – Building resources and community initiatives to onboard and empower new users.
