StackOne’s funding will be used to accelerate the integration of AI agents within enterprise systems of SaaS companies.
StackOne, the London-based AI-powered integration platform, has secured $20 million in Series A funding led by Google Ventures (GV) that also included Workday Ventures, XTX Ventures, Episode 1, Playfair, and angel investors from leading technology companies such as OpenAI, DeepMind, Microsoft, and Mulesoft.
Built to address the growing complexity and demand for real-time integrations, StackOne’s platform uses proprietary AI to automate and accelerate the connection of enterprise APIs. This allows product teams to launch integrations in days, not weeks, while ensuring security, reliability, and accuracy.
Tackling the Enterprise Integration Bottleneck
In the modern SaaS landscape, integrations have become essential for business success. According to industry data, 83% of B2B buyers prioritize integrations when choosing software solutions. However, 71% of SaaS firms face significant delays, often taking three weeks or more to launch a single integration. These delays waste valuable engineering resources and can lead to lost contracts.
StackOne was founded to solve this problem. CEO Romain Sestier and CTO Guillaume Lebedel, who have more than a decade of experience building billion-dollar SaaS products at Google, Oracle, and Yieldify, understood firsthand the urgent need for a faster, more scalable solution.
Their platform eliminates these bottlenecks by leveraging AI to create seamless, real-time integrations.
AI-First Platform Built for Speed, Scale, and Security
What sets StackOne apart is its proprietary AI integrations agent. This innovative tool simplifies the process of connecting enterprise APIs by automatically building use cases on top of complex data systems. Traditional methods that took weeks can now be accomplished in just days.
Through its robust platform, StackOne offers instant access to more than 3,000 actions across 200+ connectors. These include vital systems such as HR, CRM, ticketing, messaging, and identity access management (IAM). The AI-first architecture ensures that integrations are not only fast but also secure and up-to-date, empowering developers to focus on core product development and scaling.
Powering AI Agent Adoption Across Global Enterprises
As AI agents play an increasingly important role in enterprise operations, StackOne is positioned to become the backbone of this emerging ecosystem. By removing the friction traditionally associated with integrations, StackOne enables organizations to deploy AI agents with unprecedented ease and speed.
The platform’s growing global footprint speaks to its effectiveness. StackOne has already surpassed one billion API calls and is trusted by enterprise clients such as Drata, Attensi, and Localyze.
These companies use StackOne to streamline critical operations. For example, Drata was able to rapidly launch 100 integrations, while Mindtools implemented a Workday integration in record time to secure a major customer.
Building the Future of AI-Powered Integrations
StackOne’s mission extends beyond solving today’s integration challenges. The company is actively investing in research and development to enhance its proprietary large language model (LLM) and deepen the capabilities of its platform.
To support this vision, StackOne is building a dynamic AI developer community. Initiatives such as AI Demo Days and open-source contributions are helping foster collaboration among researchers, builders, and infrastructure teams.
Through these efforts, StackOne aims to become the central hub for developers driving the next generation of AI-powered enterprise solutions.
Strong Industry Backing Validates StackOne’s Vision
StackOne’s innovative approach and rapid growth have attracted attention from some of the most respected names in the technology industry. Luna Schmid, Partner at GV, noted the company’s bold ambition and clarity of purpose. She emphasized that StackOne is not just another SaaS integration platform, but foundational infrastructure for the future of AI and enterprise software.
Barbry McGann, Managing Director and SVP at Workday Ventures, praised StackOne’s ability to deliver deep, scalable integrations without sacrificing compliance or functionality. This ability to balance speed and reliability has made StackOne a preferred partner for enterprises worldwide.

With its fresh capital, cutting-edge AI technology, and growing list of enterprise clients, StackOne is setting a new standard for integrations in the AI era. By combining speed, security, and scalability, the platform enables SaaS vendors and AI agent builders to connect effortlessly with complex enterprise systems.
