Josh O'Connor and the Long Work of Making ClickUp Fit in a Pocket
Before ClickUp could travel in a pocket, someone had to decide what the pocket could live without. O'Connor's public trail is a decade-long lesson in mobile engineering: make the sprawling useful, make the complicated feel obvious, then keep shipping.
SVGator and the art of skipping the handoff
A moving icon should not need a production committee. SVGator puts drawing, animation and web-ready exports in one browser tab - and makes the last step part of the design.

David DeRemer

With nearly two decades spanning Accenture, frog design, Chobani, and his mobile agency Posse, DeRemer bet the company on Google's then-pre-alpha Flutter framework and turned VGV into one of the most influential consultancies in the Flutter ecosystem, helping enterprises ship high-quality apps from a single codebase.

Based in Phoenix, Arizona, he turned a side project teaching Firebase and Angular into one of the most influential developer education platforms on the internet, complemented by his course platform fireship.io and an 8,000-member developer Slack community.
FlutterFlow
FlutterFlow is a Mountain View-based visual development platform built on Google's Flutter framework. Two ex-Google engineers built it so designers, founders, and engineers could ship native mobile and web apps without writing the boring parts. Today it has more than 1.3 million users in 200+ countries, around 10,000 paying customers, and an AI layer that turns prompts into pages.
Luciq
Luciq (formerly Instabug, pronounced LOO-sik) is the San Francisco-based mobile observability company that pivoted in September 2025 from passive bug reporting to what it calls Agentic Mobile Observability - autonomous AI agents that detect, triage, and resolve issues across the mobile app lifecycle. The Y Combinator-backed company powers apps for DoorDash, T-Mobile, Verizon, and Decathlon, with more than 25,000 teams on its SDKs.
Abel Mengistu
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
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.
Sandeep Panda
Sandeep Panda is the Co-Founder and CTO of Hashnode, a developer-first blogging and community platform that lets software engineers own their content and publish on custom domains. Founded in 2016 alongside Syed Fazle Rahman, Hashnode has grown to serve 3M+ monthly readers and 10M+ monthly views, backed by Sequoia Capital India's Surge, Salesforce Ventures, and angel investors including Naval Ravikant and Guillermo Rauch (Vercel). A graduate of IIIT Bhubaneswar with a background in web development and technical writing, Sandeep has authored books on AngularJS and HTML5, and is now building Bug0, an AI-native end-to-end testing platform.

Autosana AI
Autosana AI is the first agentic QA platform for iOS, Android, and Web. Founded by Yuvan Sundrani and Jason Steinberg in June 2025 and backed by Y Combinator (S25 batch), Autosana replaces brittle test scripts with AI agents that navigate apps like real users, described in plain English. The company raised $3.2M in February 2026 from YC, Pioneer Fund, Phosphor Capital, DeVC, 468 Capital, and angels including Paul Graham. Revenue is growing 100%+ month over month, and the platform now protects apps serving over 100 million daily active users. The name comes from the Latin 'autosana' — to heal oneself — reflecting tests that evolve alongside the product rather than breaking on every UI change.
