Tempo vs ElevenLabs
Side-by-side comparison of AI visibility scores, market position, and capabilities
Toronto AI React design-engineering platform integrating with existing production codebases for 10x faster UI building; YC $5M Oct 2025 seed competing with Cursor and Vercel v0 for design-to-code tooling.
About
Tempo is a Toronto-based AI-powered design-engineering platform — backed by Y Combinator with $5 million in seed funding raised in October 2025 from YC, Golden Ventures, Box Group, Webflow Ventures, iNovia, and General Catalyst — providing a visual code collaboration environment where product managers, designers, and engineers can build React UIs 10x faster by combining familiar design tool UX with full IDE functionality and production codebase integration. Founded in 2023, Tempo differentiates from AI coding tools (Cursor, GitHub Copilot) that generate new codebases by integrating seamlessly with existing React production code — enabling teams to modify, extend, and build on live codebases visually without the "generate from scratch" workflow that can't scale to complex existing products.
$500M Series D at $11B valuation (Feb 2026) — largest voice AI funding round ever. $330M ARR; 1M+ developers using the API. Enterprise customers: Deutsche Telekom, Revolut, Meta, Salesforce. Voices in 32 languages; real-time cloning from 1 second of audio.
