Ex-Spotify engineers raise $10M to port Spotify's recommendation engine to e-commerce

Malachyte, founded by three engineers who built Vector AI — the system powering roughly 90% of Spotify recommendations across 800 million users — raised a $10M seed round on August 6, 2026, co-led by Bessemer Venture Partners and Gradient. The startup adapts that architecture for real-time product personalization on Shopify and via API.
