Should marketplaces “index” themselves in LLMs / employ AEO (Answer Engine Optimization)?

Yes — if you already index in Google, you should also index in LLMs (i.e. make your content discoverable by AI answer engines) to benefit from that traffic. The exception is when a marketplace has ~95% market share in a vertical: in that rare case, indexing might train users to start their journey with LLMs / search engines rather than the marketplace itself.

What impact is AI already having on marketplaces?

Several: • Cross-border commerce via auto-translation of listings & conversations plus better payments/logistics. • Simplified listing process: AI can generate full listings (title, category, description, price) from minimal input. • Improved listing quality (better images, background removal, optimized visuals) leading to higher sell-through. • Productivity gains in customer support, marketing, dev workflows etc., through AI agents, auto-drafted replies, code generation tools etc.

What are the main ways people shop online, as per the blog?

1. Shopping as Entertainment – browsing listings with no specific intent (e.g. Vinted, OLX); 2. Search – users know exactly what they want (e.g. Amazon, eBay); 3. Considered Purchases – when buyers need help choosing what to buy (e.g. high-value items, specialty goods)

How might LLMs (like ChatGPT) threaten marketplaces?

The concern is that LLMs could capture the "top of funnel" discovery phase: people might start product searches there, or even make purchases through them, bypassing marketplaces.

If you are an amazing founder, but feel the valuation is too high or the business not compelling, we will not invest. Likewise, if it is a great idea, great terms, and full-on thesis, but we feel the team is mediocre, we do not invest.” (Fabrice Grinda)
