8 months ago, OpenAI invited me to San Francisco to shoot a first documentary on how Silicon Valley startups use AI to build their products.
This time, Figma invited my Co-Founder David and me.

So we spent 3 days at Config, Figma's yearly gathering in San Francisco. 10,000+ designers from the biggest tech companies came to see what's next.
Our question, the same as last time but more focused: what is AI really doing to the designer's job?

Over 1 week, we interviewed more than 30 designers from very different companies, right on the floor of Config.

We also had the chance to interview the VP Product and the VP Design at Figma.
We attended the keynote from Dylan Field, Figma's CEO and watched Figma announce Code Layers, a launch that redraws the line between design and code.
What we're bringing back: some designers are more excited than ever.
Others are clearly worried.
No one gives the same answer to the same question.

A few of the topics we dig into:
How designers are actually experiencing the AI shift
What Figma is preparing next with Code Layers
Where the real value of a designer sits now
What AI can never take from a designer (and why nobody agrees)
How to design products for AI agents

Enjoy.

In this episode, I have the pleasure of welcoming Nicolas Dessaigne, Partner at Y Combinator, one of the most influential startup accelerators in the world. Nicolas is a repeat founder who co-founded Algolia, a company that became one of Europe’s biggest B2B SaaS successes before expanding globally. Today, he supports hundreds of founders as part of YC, helping shape the next generation of iconic startups. We recorded this conversation in San Francisco, where Nicolas shared his unique perspective on how YC has evolved — from 2 batches a year to 4 — and how this new AI era is transforming the way startups are built. We talk about the new wave of AI-native founders, why product iteration speed matters more than ever, and how large companies are struggling to keep up with the pace of change. Nicolas also shares what makes YC truly unique, the role of technical founders, and why code is no longer the moat it used to be. If you’re a founder, a product builder, or just curious about how YC sees the future of startups in the AI era, this episode will give you a rare inside look.

In this episode, I’m really excited to welcome Spenser Skates on Clef de Voûte.
Spenser is the co-founder and CEO of Amplitude, the digital analytics platform that helps more than 4,500 companies around the world understand their users and build digital products that matter.
In our conversation, Spenser will share what it really takes to grow from the scrappy early days to meaningful enterprise scale : the trade-offs, the tough choices, and how you keep moving fast as the company gets bigger. We’ll also talk about building real product differentiation with AI : how to see through the hype, spot what’s real, and focus on long-term value rather than chasing trends. And finally, Spenser will give us a look at Amplitude’s roadmap for AI : where the company is headed next, how they’re planning to deploy AI, and how it will positively impact their customers.

In today’s episode, I’m glad to be with Marie Martens, Co-Founder of Tally.

Marie co-founded Tally, a simple yet powerful online form builder, to solve a small frustration, and ended up challenging the biggest software companies on the market without raising a single dollar of venture capital.

With over 1 million teams worldwide using their product, her bootstrapped journey proves that keeping things radically simple can be your biggest competitive advantage.

In this episode, we explore how ignoring traditional startup rules and giving away core features for free fueled massive product-led growth.

We dive into the daily realities of staying intentionally small, turning down lucrative enterprise clients, and leveraging transparent public building to generate authentic word-of-mouth.
Marie also shares her direct experience with the unexpected challenges of AI-driven customer acquisition.

We talk about :

Bootstrapping a global software product with a tiny team.
Using a viral free tier instead of hiring a sales department.
Turning down large corporate clients to maintain product focus.
Acquiring the first users through unscalable manual outreach.
Navigating the unexpected churn consequences of ChatGPT referrals.

Have a good listening !

Dans cet épisode, j'ai le plaisir de recevoir David Zitoun, co-fondateur de Submagic.
Lancé en plein essor de l'IA générative, Submagic permet aux SMBs de créer du contenu vidéo sans réelles compétences.

David a fait le choix radical du bootstrap à une période où les levées de fonds de Produits IA s'enchaînent.

Dans cet épisode, on aborde :
Comment générer 1M d'ARR en 3 mois sans financement.

Comment trouver son PMF grâce à 1 fonctionnalité.

Quelles stratégies d'affiliation et d'influence activer.

Comment scaler sans équipe Sales.

Pourquoi recruter un profil Produit pour optimiser la conversion.

Bonne écoute.
