About Gelato

Gelato has built the world's largest and most global network for on-demand production of customized items e.g. t-shirts, wall art, mugs, books, hoodies, and cards. We support a new wave of e-commerce entrepreneurs and the global shift towards local and more sustainable production.

In many ways, we at Gelato are rethinking how digital fabrication of customized products can be done on-demand. Just imagine what will happen when we add 3D printing capabilities to this global service. We are already empowering thousands of e-commerce entrepreneurs to grow and scale their businesses.

Platform

Gelato is an AI-first, cloud-native platform transforming local, on-demand production and delivery — with zero physical assets. We power:

• Global production orchestration: connecting e-commerce customers to 130+ partners across 32 countries. From AI-guided plate design to smart routing and logistics, we deliver to over 5 billion people in under 72 hours—faster, greener, smarter.

• GelatoConnect: our AI-driven print production OS that helps producers master digital printing — from inventory to shipping — by automating every step: procurement, prepress, printing, packaging, and dispatch. It’s machine-agnostic, real-time, and built for uptime, precision, and profitability.

• AI-first development using LLMs for code generation, testing, documentation, and design exploration.

• Autonomous AI agents driving platform resilience, observability, cost control, and internal workflow automation.

• AI-native product features built into GelatoConnect and the core platform — improving routing, personalization, and production optimization.
