Abel Mengistu is the cofounder and CEO of FlutterFlow, the low-code visual app builder that has enabled over 2 million users to create production-ready Flutter applications without deep coding expertise. A former Google senior software engineer who worked on Google Maps and ATAP hardware, he co-founded FlutterFlow in 2020 with Alex Greaves after a failed restaurant-recommendation startup taught them the real bottleneck was app development complexity. Accepted into Y Combinator's Winter 2021 batch after applying past the deadline, they famously survived 'No-sleep November' to build FlutterFlow 1.0 in a single month. The company raised a $25.5M Series A from GV (Google Ventures) in January 2024, has grown to 173 employees, and in 2025 launched Dreamflow - an AI-powered builder that generates production-ready app screens in roughly 10 seconds.
Alex Greaves is the Co-Founder and CTO of FlutterFlow, a visual low-code/AI-powered app development platform he co-founded in 2020 alongside fellow ex-Googler Abel Mengistu. Built on Google's Flutter framework, FlutterFlow has grown to serve over 2 million users across 200+ countries, backed by $25.5M in Series A funding led by GV and Gradient Ventures at a ~$170M valuation. A Stanford physics and CS grad who honed his craft on Google Maps' machine learning team, Greaves now leads a platform that lets developers and non-developers alike ship native iOS, Android, and web apps in a fraction of traditional development time.

Sergie Magdalin is the co-founder and Chief Experience Officer of Webflow, the visual web development platform that lets designers build production-ready websites without writing code. Alongside his brother Vlad Magdalin and Bryant Chou, Sergie — a former freelance graphic designer and UX designer — built Webflow from a rejected Y Combinator application into a $4B company with over 3.5 million users. His design sensibility shaped Webflow's core UX, including pioneering visual interaction tools and a responsive design system that democratized professional web publishing.
