Senior Product Designer; AI Commerce

Founded by Paul Anthony, creator and co-founder of Primer (Series B, $425M valuation), Colossal is building at the intersection of generative app development and commerce infrastructure. Think:
Lovable for commerce, but for non-developers.

We’re backed by Tier 1 investors:
Seedcamp, 10x Founders, Connect Ventures, and are planning to raise our seed round later this year.

The software landscape is rich with tools and services to help businesses build their ideal commerce solutions, but these are fragmented and demand deep knowledge of the commerce value chain to get the most out of.

We’re building an ambitious new platform for online sellers to craft their ideal commerce experiences for their unique customer base, leveraging the latest AI has to offer. We’re still in stealth mode, so get in touch to learn more. 🥷

At Colossal, Product Design is not seen as an internal stakeholder executing pre-defined concepts. Design sits at the centre of our product efforts, and involves constant collaboration, research and creative problem solving. Design is here to uncover insights, challenge assumptions, and help us build a category-defining product.
