What themes were used during his multi-day birthday celebrations?

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.

Why did Fabrice pause investing after his first batch of startups?

Why was FJ Labs created as both a startup studio and a venture fund?

FJ Labs was designed as a hybrid model so Fabrice could keep building companies while also investing. Being both an entrepreneur and an angel investor kept him close to founders, allowed him to help with ideas, and gave him insight into market trends.

What is required to make the investment decision at FJ Labs?

“When we evaluate startups over the course of our two 1-hour calls, we evaluate them along the four dimensions we covered: the team, the business, the deal terms, and alignment with our thesis. We want all four criteria to be conjointly met: amazing founders, with great businesses, raising at fair terms, in line with our thesis. 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)

How important is thesis alignment in FJ Labs’ evaluation?

“We focus on marketplaces and have specific theses on the future of marketplaces. Right now, we are specifically focusing on: Verticalizing horizontal (multi-category) platforms; Marketplace pick marketplaces; B2B marketplaces. … Most of the businesses we invest in touch upon many of these themes simultaneously.” (Fabrice Grinda)

What does “fair deal terms” mean at FJ Labs?

“We push for ‘fair valuations’ not just out of self-interest. We really think founders do themselves a disservice when they raise too much money at too high a price. … They are then priced for perfection … things do not go according to plan … it might kill the company … people who raise too much capital tend to spend it and not be as capital efficient as they can be.” (Fabrice Grinda)

(This is under “Do we like the business?” but the blog focuses more on the team, deal terms, thesis. It states that even if team is great, business with unattractive unit economics or business model may disqualify.) (Fabrice Grinda)

What does FJ Labs look for in the team?

“We want visionary founders who are fantastic at execution. … good proxies for those are storytelling skills and analytical skills. … the founder / CEO must also be metrics-driven, analytical and know how to execute on his or her vision. They really need to understand the business they are in. They need to be able to articulate their unit economics. Even if their business is pre-launch, they need to understand their theoretical unit economics based on industry averages and landing page tests they did.” (Fabrice Grinda)

What percentage of follow-on rounds does FJ Labs participate in?

They follow on in about 24% of cases. They use the fund active at that time, instead of reserving capital.

They aim to give an answer in 1–2 weeks so founders aren’t left waiting.

How many deals do they review before investing?

In 2019, they reviewed 2,542 deals and invested in only 83 first-time investments — about 3%.

How does diversification help their investment strategy?

Venture returns follow a power-law: most returns come from a handful of winners. By investing in many companies, FJ Labs increases the odds of hitting those outliers.

Taking board seats would limit the number of companies they could back. Since they invest at scale, they avoid it and instead help founders informally.

En 2024, el fondo de cobertura de renta variable global de Numerai ofreció una rentabilidad neta del 25,45% con solo un mes de pérdidas y un Sharpe del 2,75. Con el nuevo capital social y la capacidad de JP Morgan, la empresa está ahora en condiciones de ampliar su fondo de cobertura de IA hasta alcanzar los 1.000 millones de dólares en activos bajo gestión y más allá.

En el evento FII Institute de este año en Riad, Jeff habló en un panel de Kauffman Fellows sobre la «Evolución de una empresa de capital riesgo» junto con socios generales de Monashees & Deciens. El grupo profundizó en los cambios clave de mentalidad y los cambios estructurales necesarios para escalar un fondo hasta convertirlo en una empresa.
