Value proposition

Sekai is the first AI-native social platform defining "Software as a New Media." It lets anyone, regardless of technical skill, generate playable mini-apps from text prompts in seconds, then share and remix them in a social feed. Users can create games, utilities, quizzes, and interactive experiences without coding.

Products and solutions

Sekai mobile app (iOS & Android) — AI-powered interactive content platform for creating, playing, remixing, and sharing mini-apps, Web-based exploration and discovery, AI-powered coding agents that translate plain-language descriptions into functional interactive applications, Remix feature for forking and modifying others' creations

Unique value

"TikTok for software" — the first platform to make interactive mini-apps as easy to create and share as short-form video. AI-powered creation from text prompts, social feed with remix culture, and zero-code barrier to entry for building functional software.

Target customer

Consumer creators and users — the same demographic that posts cooking videos on Instagram or creates memes in Canva; Gen Z and Millennial social media users interested in interactive content creation and consumption

Industries served

Consumer social entertainment, User-generated content, No-code app creation, Interactive gaming, Digital storytelling

Technology advantage

AI-powered coding agents that translate natural language into functional interactive apps; AI-native architecture where the product improves automatically as models evolve; Self-iterating code and agent-based creation pipeline; Total personalization at scale; Team of TikTok veterans with experience scaling platforms to hundreds of millions of users across multiple continents

How they differentiate

Unlike enterprise no-code tools (Bubble, Webflow, Retool) that target businesses, Sekai targets consumers with a TikTok-style social feed and remix culture. Unlike other AI content platforms focused on text/image/video generation, Sekai generates interactive software — the last major creative category with a high barrier to entry. The team's unique background includes building TikTok's largest rival in Latin America and scaling platforms to hundreds of millions of users.
