GV Invests $20M in AI Startup StackOne

## Exclusive: GV Backs AI Startup StackOne in $20m Funding Round As we step into the vibrant landscape of artificial intelligence in 2025, a significant development has caught the attention of tech enthusiasts and investors alike. StackOne, a London-based AI startup, has secured a substantial $20 million Series A funding round led by GV, formerly known as Google Ventures[1]. This investment marks a pivotal moment for StackOne, which specializes in providing cutting-edge embedded integration platforms as a service (IPaaS) for the enterprise software-as-a-service (SaaS) sector. GV's backing of StackOne is part of its broader strategy to invest in AI startups that address complex, high-impact problems in the enterprise SaaS space. With its focus on applied AI and enterprise solutions, GV aims to empower startups that can deliver tangible value through innovative technologies[5]. For StackOne, this funding is a testament to its vision of streamlining integrations for SaaS vendors, making it easier for them to connect with various enterprise tools and systems seamlessly. ### Background: StackOne's Founding and Mission StackOne was founded by Romain Sestier, who previously worked at Google, and Guillaume Lebedel. The company's mission is to revolutionize how SaaS vendors approach integrations by providing a unified API that facilitates enterprise-grade B2B integrations across industries[4]. This approach has resonated with investors, who see the potential for StackOne's platform to simplify complex integration processes, ensuring that SaaS clients deliver the best possible integrations to their customers and partners. ### Seed Funding and Expansion Plans Before securing the Series A funding, StackOne successfully raised $3.6 million in seed funding in March 2024, led by Episode 1, with participation from notable investors such as Playfair Capital and Sequoia’s Scout fund[2][4]. This initial funding round was used to invest in AI technology and expand StackOne's presence in the US, EU, and Australian markets. The addition of GV to StackOne's investor roster adds significant weight to its expansion plans, particularly in leveraging AI to enhance its unified API offerings. ### The Role of AI in StackOne's Platform StackOne's integration platform leverages AI to offer customizable, real-time unified APIs for B2B SaaS companies. This enables SaaS vendors to easily connect with established HRIS tools, streamlining workflows and ensuring the protection of sensitive data[4]. The use of AI in this context allows for more dynamic and adaptive integrations, which are crucial for modern SaaS companies looking to scale efficiently. ### GV's Investment Strategy in AI GV's investment in StackOne reflects its broader strategy of focusing on AI startups that solve critical problems in the enterprise space. GV has estimated its 2025 AI investments to reach $300 million, with a focus on enterprise SaaS and applied AI[5]. This approach underscores GV's commitment to backing startups that can deliver tangible value through AI technologies. ### Future Implications and Potential Outcomes The partnership between GV and StackOne could have significant implications for the future of SaaS integrations. As AI continues to play a more central role in streamlining enterprise operations, StackOne's platform is poised to become a key player in facilitating these integrations. The investment also highlights the growing importance of AI in enhancing enterprise software capabilities, pointing towards a future where AI-driven integration platforms become the norm. ### Comparison with Other AI-Driven Integration Platforms While StackOne focuses on embedded IPaaS for SaaS vendors, other companies are exploring different avenues in AI-driven integration. For instance, platforms like MuleSoft and Zapier have been leveraging AI to automate and simplify integrations across various industries. However, StackOne's focus on providing a unified API specifically for enterprise SaaS applications sets it apart, especially in its ability to handle complex B2B integrations at scale. | **Platform** | **Focus** | **Key Features** | |---------------|-----------|------------------| | **StackOne** | Embedded IPaaS for SaaS vendors | Unified API, AI-driven integrations, enterprise-grade B2B integrations | | **MuleSoft** | General Integration Platform | Anypoint Platform, API Management, Integration with various systems | | **Zapier** | Automation of workflows | AI-driven automation, integration with diverse apps | ### Conclusion The $20 million funding round led by GV marks a significant milestone for StackOne, solidifying its position as a leader in AI-driven integration platforms for the SaaS sector.
