StackOne, an AI-powered integration platform, has raised $20 million in a Series A funding round led by GV (Google Ventures), with participation from Workday Ventures, XTX Ventures, and prominent angel investors from companies like OpenAI, DeepMind, Microsoft, and MuleSoft. This funding, bringing the total raised to $24 million, will support the development of StackOne’s AI-powered tool-calling LLM and expand its integration capabilities.
The Integration Challenge and StackOne’s Solution:
In the world of SaaS, integration has become a critical component of success. However, 83% of B2B buyers view integration as a top priority, yet 71% of SaaS firms take over three weeks to launch a single connection. This delay results in wasted resources and lost contracts. The founders of StackOne, Romain Sestier (CEO) and Guillaume Lebedel (CTO), have experienced these integration struggles firsthand, having built billion-dollar SaaS products for Google, Oracle, and Yieldify.
StackOne addresses these integration pain points by providing an AI-first platform that automates and accelerates the connection of SaaS tools and AI agents to enterprise tech stacks. This solution helps businesses achieve real-time, secure, and reliable integrations, removing the manual burden typically associated with complex enterprise APIs.
AI-Powered Integration Platform for Enterprise Needs:
- AI-Driven Automations:
- StackOne’s proprietary AI agent handles the heavy lifting involved in integration. Instead of developers spending weeks on custom logic, StackOne’s AI system automatically builds use-cases on complex APIs, reducing integration times and increasing accuracy.
- Instant Access to 3,000+ Actions and 200+ Connectors:
- With StackOne, teams gain instant access to a comprehensive suite of pre-built connectors across various domains such as HR, CRM, ticketing, messaging, and IAM, enabling rapid and scalable deployment.
- Enterprise-Grade Security:
- By default, StackOne’s integrations are secure, up-to-date, and compliant with enterprise standards. This ensures that businesses can rely on the platform for safe and governed integrations while maintaining control over sensitive data.
- A New Generation of Integrations:
- StackOne’s platform is designed for global adoption, helping businesses connect AI agents to their SaaS tools, and ensuring scalability for large enterprises. With over 1 billion API calls, StackOne has already demonstrated its effectiveness for customers like Drata, Attensi, and Localyze.
Building the Future of AI-Driven SaaS:
StackOne is actively growing an AI developer community, organizing AI Demo Days, and contributing to open-source efforts. The company aims to not only provide the best integration platform but also serve as a central hub for the future of AI-powered software.
Statements from Leadership:
- Romain Sestier, CEO of StackOne, emphasized the platform’s mission to eliminate the integration bottleneck by making AI agent-driven SaaS connections a reality, built with depth, accuracy, and security by default.
- Guillaume Lebedel, CTO of StackOne, discussed how traditional integration standards such as MCP (Model Context Protocol) are insufficient for enterprise-level use, and how StackOne solves these limitations through a more robust platform.
Investor Insights:
- Luna Schmid, Partner at GV, praised StackOne’s ambition and clarity in rethinking the integration space, positioning the platform to become the infrastructure that modern AI-powered software ecosystems rely on.
- Barbry McGann, Managing Director at Workday Ventures, highlighted StackOne’s speed, scale, and its ability to facilitate AI agent interoperability, enabling powerful use cases across industries.
With $20 million in Series A funding, StackOne is poised to redefine the future of enterprise SaaS integrations by offering a secure, scalable, and AI-driven platform. This new generation of integration solutions not only addresses current industry challenges but also paves the way for the widespread adoption of AI agents in businesses worldwide.
