Alexander Kuebel
He sold duplicate Panini stickers at seven, met his co-founders at university, and learned to turn ugly integration work into infrastructure. Now Kombo's CEO is taking that very specific obsession from Berlin to New York.
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.
Remen Okoruwa
Remen Okoruwa is the co-founder and CEO of Propexo, a Y Combinator-backed Boston startup building a unified API for property management software. Pitched as 'Plaid for commercial real estate,' Propexo lets engineers connect to legacy systems like Yardi, RealPage and Entrata in days instead of months. An Iowa kid who studied engineering at Harvard, Remen took a winding road through McKinsey, a churn-fighting data startup, product leadership at HubSpot, and a rent-payments venture before landing on the unglamorous but enormous problem of moving property data. He now powers integrations behind more than half of the NMHC Top 15 managers.
Gregg Mojica
Gregg Mojica is the founder and CEO of Kinter.ai, the AI-accounting company that grew out of Alloy Automation, the integration platform he co-founded with Sara Du in 2019 (YC W20). He started coding at 12, shipped three apps before he turned 18, got into Cornell and skipped it to build payments infrastructure at First Data/Fiserv, then helped build Alloy into the connective tissue for thousands of ecommerce and AI-agent workflows backed by a16z and Bain Capital Ventures. Today his AI Accountants close the books for enterprises including Amazon, Mastercard and UPS.
Peter Zhou
Peter Zhou is the co-founder and CEO of Rutter, the New York-based unified API that connects business financial data across accounting systems, commerce platforms, payment processors, and ad networks. Often described as the 'Plaid for commerce,' Rutter lets B2B fintech companies plug into QuickBooks, Shopify, Amazon, Stripe and dozens more through a single consistent schema. A Yale-trained computer scientist and Y Combinator alum, Zhou and co-founder Eric Yu pivoted through years of failed startups before landing on Rutter, which raised a $27M Series A led by a16z in 2022.
Gil Feig
Gil Feig is the Co-Founder and CTO of Merge, the unified API platform that lets B2B software companies add hundreds of integrations to their products in days instead of months. He started coding at 12, got a cease-and-desist from Facebook at 16, and launched Merge in the middle of COVID after interviewing 100 companies before writing a single line of code. The company has raised $74.5M, serves 4,000+ customers, and named Feig and co-founder Shensi Ding to the 2023 Forbes 30 Under 30 list.
Nathan Stewart
Nathan Stewart is a founding engineer at Merge (merge.dev), the unified API platform that lets B2B SaaS companies connect to hundreds of HRIS, ATS, CRM, accounting, and ticketing systems through a single integration. Based in New York and educated at The Ohio State University, Stewart is a backend developer who joined Merge in its early days and has helped scale the company to over 140 employees and $74.5M in funding. He describes himself as a 'Software Engineer & Puzzle Aficionado,' an apt description for someone building the connective infrastructure that keeps the modern SaaS stack wired together.
Shensi Ding
Shensi Ding is the co-founder and CEO of Merge, the unified API platform that lets B2B software companies offer hundreds of product integrations by integrating just once. A Columbia computer science graduate who detoured through investment banking at Credit Suisse and Silver Lake before becoming Chief of Staff at Expanse, she co-founded Merge in 2020 with college friend Gil Feig after they spent six months talking to 100+ companies about integration pain — without pitching a single solution. Merge has since raised $75M from Accel, NEA, and Addition, serves 7,000+ customers including Calendly, Gong, Ramp, and Brex, and has become critical infrastructure for the AI era as LLMs need real-time access to third-party data.
Jeremy Zhang
Jeremy Zhang is the co-founder and CEO of Finch, a San Francisco-based company building the unified API layer for employment systems. After studying Electrical Engineering and Economics at Duke University and engineering connected-car APIs at Smartcar, Zhang co-founded Finch in 2020 with Ansel Parikh to solve a deceptively simple problem: why does every HR and payroll software company make developers rebuild the same integrations from scratch? Finch now connects 200+ HR and payroll providers, covers 88% of U.S. employers, and has processed data for 18+ million employees. The company has raised $58.5 million in venture funding from General Catalyst, Menlo Ventures, and Y Combinator.
