The browser startup once fought ugly slides by limiting your choices. A decade later, that same constraint has become its enterprise pitch: turn approved assets and customer data into personalized content without letting every salesperson freelance the brand.
Sekai is a San Francisco Bay Area consumer platform where anyone can build software just by describing it. Users type a prompt and get a playable, shareable mini-app - a game, quiz, utility, poll or interactive story - in seconds, then play, remix and share what others make. Founded in 2024 by serial entrepreneur Lucky Zhang, Sekai (Japanese for 'world') began as an AI anime fan-fiction tool and pivoted into general-purpose app creation as AI coding models improved. By mid-2026 users had created more than 15 million mini-apps, with roughly 200,000 new ones a day, and the company had raised about $26 million across Seed and Series A rounds from Khosla Ventures, Connect Ventures, a16z speedrun, Mayfield and others.
Arcade is a San Francisco software company that lets go-to-market teams build interactive product demos in minutes instead of weeks. Using a Chrome extension or desktop app, users record their product, then add pan-and-zoom, hotspots, synthetic voiceovers, and branching paths to create clickable 'arcades' that can be embedded in websites, emails, and social posts. Founded in 2021 by former Atlassian colleagues Caroline Clark and Rich Manalang, the company turns the old 'request a demo' wall into a 'try before you buy' experience, and is used by more than 14,000 companies including Zapier, Red Hat, and New Relic.
