He did YC in 2016 from France with a Slack bot nobody had heard of.

9 years later, he came back… second company, second batch, $10M seed closed in 3 days. Dalton told him: "Don't overlearn."

Quang is the founder of Vybe, a YC W25 company building the internal app layer for the AI era. Before that: Plato, a mentorship platform for engineers he grew to 70 people, raised $22M for, and sold to Coda, where he worked as a GM before quitting to start over.

In this conversation, we go deep on what it actually means to be a second-time YC founder: the overcorrections, the traps, and what's genuinely different about YC today vs. 2016.

In this episode, you'll learn:

→ Why hiring zero people after raising $10M was the wrong overcorrection, and when Quang finally figured that out

→ How selling before the product was ready backfired, and what First Round's Liz told him to do instead

→ YC's self-fulfilling prophecy: how the program became a distribution machine, and why seed rounds that took 3 weeks in 2016 now close in 3 days

→ Why Vybe is quietly pivoting from "build internal apps" to "agents that use those apps", and what inspired it

→ The three-component PMF framework First Round runs with every portfolio company (and where most founders skip straight to step 3)

The recovery market is broken, and most VCs are too scared to touch it.

After a successful exit at Rupa Health, Koby moved to Buenos Aires with nothing but a backpack to "vibe code" the future of sobriety.

In this episode, we dive into the "no-meeting" SAFE phenomenon, why SaaS moats are dying, and how Sunflower reached $1M ARR in record time.

What you will learn:

• Why the "Wellness" category is a trap for serious founders.
• How to raise capital in "emotionally difficult" or stigmatized markets.
• The strategy behind giving away software for free to monetize physical "atoms."
• Inside the YC Fall 25 batch: What has changed since 2019.

The US government spends $2.7 trillion a year on everything from water bottles to fighter jets, yet the entire process is held together by Microsoft Word and tribal knowledge.

In this episode, we sit down with August Chen, founder of Hazel (YC W24), to discuss why he left Palantir to tackle the antiquated world of government procurement. We dive into the "missionary vs. mercenary" mindset, the reality of the 1% acceptance rate at YC, and why the "death of the paper-pusher" is the greatest opportunity in VC today.

What you’ll learn:

• Why 50% of small businesses have abandoned government contracts.
• The Palantir playbook: How to "deploy yourself" into a customer's workflow.
• Why selling to the Government requires a "hierarchy of needs" approach.
• The pivot from B2B2G to direct B2G: When the mission stays, but the product moves.
• How AI is turning months of RFP paperwork into seconds of work.
• Predictions for the "DOGE" era and the future of civil servant tech stacks.

The most successful YC companies aren't always the loudest. They're the ones that survive the "Valley of Death" to become indispensable infrastructure.

In this episode, I sit down with Grant Shaddick, founder of Tella (YC W20), the video tool that has quietly taken over the YC ecosystem. We dive into the grit required to build a category leader, why they chose to stay lean while others over-raised, and how AI is finally killing the "video editing" bottleneck.

What you’ll learn:

• Why "boring" infrastructure often outperforms "hype" AI startups.
• The reality of the startup "Valley of Death" and how to survive it.
• Why a high valuation can actually be a founder's biggest trap.
• The future of agentic video editing: from tools to outcomes.
• The secret behind Tella’s viral adoption among YC founders.

YC just added one question that quietly changes what it means to be a founder.

And it’s not about your TAM. It’s not about your pitch. It’s about how you use AI to build.

In this episode of Lobster Talks, we break down YC’s newest application change, the rise of coding agents like Claude Code, and what this signals about where startup building, and venture capital is heading next.

We also go deep on YC Roaster, Lobster Capital’s new initiative helping founders improve their YC applications using AI + YC alumni review.

Here’s what you’ll learn:

- Why YC’s new “coding agent session” question is a founder filter

- How vibe coding is becoming table stakes in 2026

- What 20,000 YC applications really signal about global founders

- Why traction keeps rising as the YC acceptance bar

- How smart VCs are building internal tools and why most aren’t

- Why the best founders and funds pivot fast

This is a behind-the-scenes look at how YC evaluates builders today.

Most people treat their bodies like a car they only fix after it crashes.

Max Berthelot and Lucis are rewriting that script by turning longitudinal blood data into a high-margin, preventive software play.

In this episode, we sit down with Max Berthelot, founder of Lucis (YC S25), to discuss why "Function Health for Europe" is one of the most compelling arbitrage opportunities in the venture world.

We dive into the cultural shift of paying for health in Europe, the technical challenge of scaling doctor-supervised AI, and the relentless execution required to expand across five countries in record time.

What you’ll learn:

- Why blood data is the "Gold Rush" of the next decade.

- The YC strategy for conquering fragmented European markets.

- How to maintain "San Francisco Velocity" while based in Paris.

Factories don’t buy hype. They buy uptime.

In this episode, YC-backed Cerrion CEO Karim Saleh explains why industrial computer vision is one of YC’s most underrated AI wedges, and why it can beat flashier “copilot” markets on sheer dollar-weight and defensibility.

Karim breaks down how Cerrion deploys camera-based AI agents to detect production issues in real time, why manufacturing is a $20T opportunity, and what most investors get wrong about selling into factories. If you’re building “real-world AI,” this is the playbook… from five paid pilots before code to scaling via workflows, not dashboards.

What you’ll learn:

• Why YC keeps funding industrial computer vision (even across hype cycles)
• The technical truth: every factory is different… and why VLMs change the game
• The go-to-market wedge that wins: small scope → fast ROI → expansion (NRR)
• How Cerrion embeds into daily factory workflows (shift meetings, handovers, owners)
• The biggest investor myth about manufacturing sales cycles, and the real unlock
• Why competition-heavy AI markets are a trap (and what to build instead)

Lawyers hate tracking time. PointOne turned that universal pain into an AI wedge, and used the YC playbook to move fast in one of the most conservative, high-ARPU markets on earth.

In this episode of Lobster Talks, Katon Luaces (YC ’24) breaks down how PointOne built an “AI time platform” for law firms, why “hard thing first” compounds, and what investors routinely misread about early traction vs. real product validation.

You’ll learn:

- Why “why now” is the only filter that matters for AI startups

- How PointOne got early users fast with aggressive cold outbound

- The “hard thing first” strategy—and why it creates real moats

- The truth: early traction validates the problem, retention validates the solution

- How to sell AI into skeptical industries with “stepping-stone” adoption

- Why AI law firms are real… but “one law firm in the future” is unlikely
