Romain Sestier
Romain Sestier is the co-founder and CEO of StackOne, an integration platform that lets B2B SaaS products and AI agents connect to hundreds of enterprise systems through one unified API. After a decade spent maintaining integrations by hand at companies like Maxymiser, ContentSquare and Yieldify, and after building a product from zero to $1 billion in incremental revenue at Google, he and long-time collaborator Guillaume Lebedel started StackOne in 2023 to build the integration layer they always wished existed. The company reached six-figure revenue within weeks of launch and raised a $20M Series A led by GV in May 2025.
LinkToAny
LinkToAny (formerly ShoppinPal) is a Los Angeles-based integration platform that helps commerce software providers onboard merchants, migrate data between systems, and connect the apps a business already runs. Its iPaaS-style platform links point-of-sale, ecommerce, accounting, loyalty and ordering systems - working with names like Shopify, Lightspeed, Clover, Intuit/QuickBooks, Square, GoDaddy and PayPal - so platforms can go live with new merchants in days rather than weeks, with an increasingly AI-native approach to onboarding and migrations.
StackOne
StackOne is a London-based integration platform that gives B2B SaaS companies and AI agent builders a single unified API to connect to hundreds of enterprise systems - from HR and CRM to ticketing, messaging and identity. Combining a proprietary tool-calling LLM with a real-time, privacy-first engine, it offers 200+ pre-built connectors and thousands of ready-made actions so agents can reliably and securely take actions inside the software businesses already use. Founded in 2023 by Romain Sestier and Guillaume Lebedel, the company raised a $20M Series A led by GV (Google Ventures) in May 2025 and has surpassed 1 billion API calls.
Pipedream
Pipedream is a developer-first integration and automation platform that lets engineers connect more than 3,000 APIs and 10,000+ pre-built actions to build workflows, products, and AI agents without managing infrastructure. Founded in 2019 in San Francisco, it grew to more than one million users on the strength of a serverless model that mixes drag-and-drop triggers with full Node.js, Python, Go, and Bash code. In 2025 it became the connective tissue for AI agents through its Model Context Protocol (MCP) servers, and in late 2025 it agreed to be acquired by Workday.
Rich Waldron
Rich Waldron is the Co-founder and CEO of Tray.ai, a San Francisco-based enterprise AI automation and integration platform. He co-founded the company in 2012 out of the UK alongside Alistair Russell and Dominic Lewis, famously surviving 3.5 years without salary by running a web agency, publishing a magazine, and selling shoes on eBay. Under his leadership, Tray.ai has raised $149.1M in funding (most recently a $40M Series C extension in 2022), earned Gartner Visionary recognition in 2024 and 2025, and evolved from an iPaaS provider into an AI-ready enterprise orchestration platform championing the concept of the 'Autonomous Enterprise.'
