In 2025, Sara Du identified challenges in integrating AI agents within communication platforms like Slack while assisting companies with MCP servers. She criticized the design of these platforms for treating AI agents as separate applications rather than team participants. Du proposed a solution to eliminate intermediaries between AI agents and teams, envisioning a system where agents could engage directly in conversations, understand decisions, ask questions, and autonomously notify humans when necessary.
Du's startup, Ando, launched as a messaging platform that allows both human and AI workers to communicate seamlessly, featuring channels, direct messages, and live calls. Ando has raised a million in pre-seed and seed funding from firms like Accel and Index Ventures. Despite existing competition from platforms like Slack and Microsoft, Du sees potential for Ando to disrupt the market by focusing on AI agent integration. Currently, Ando works with clients in software, real estate, and finance across 15 countries, primarily small teams, and aims to expand its capabilities with the new funding.
