Most founders think they need to monetize on day one, but this YC breakout grew to 2 million weekly downloads by giving everything away for free, and now they power ChatGPT.

In this episode of The Lobster Talks, we sit down with Bereket, the founder of BetterAuth, to dissect the ultimate open-source distribution playbook.

Moving directly from Ethiopia to Silicon Valley, Bereket built an authentication powerhouse that is disrupting legacy vendors and establishing the new standard for the AI agent economy.

We break down the transition from human auth to agent identity, the playbook behind corporate acquisitions like Anthropic buying Bun, and why rushing your monetization strategy can kill your hypergrowth.

What you will learn:

• The exact mechanics BetterAuth used to scale from 150K to 2 million weekly downloads without a marketing budget.
• Why building a high-quality open-source ecosystem is the highest-leverage distribution hack in tech.
• How Anthropic’s acquisition of Bun proves that massive developer utility trumps early monetization.
• The unbundled future of identity: Why the massive explosion of AI agents requires a completely new auth protocol.
• How Claude Code and LLM recommendations are completely replacing traditional B2B SaaS marketing funnels.

The consensus view is that early-stage investing is entirely about a gut feeling on game day. The reality? By the time the first founder steps on stage at Y Combinator’s Demo Day, the best deals are already effectively closed.

In this episode of The Lobster Talks, we sit down with David, founder of Fondo and a seasoned YC alum who has navigated the Demo Day trenches for over a decade as both a founder and an investor. We strip away the mythology of Silicon Valley’s most exclusive deal-making event to give you the tactical playbook for navigating a hyper-competitive, founder-first market.

What you will learn:

• How to build a high-conviction shortlist weeks before Demo Day using Launch YC.
• The unwritten etiquette rules of the YC investor database and how a bad rating can ruin your deal flow.
• Why negotiating valuation as a small check is an immediate amateur signal.
• The mechanics of the "Handshake Agreement" and why breaking it is catastrophic for your reputation.
• The exact timelines required to close allocations before the herd catches up.

Big tech is staring down a multi-year bottleneck. and it isn't chips... it's power.

While hyperscalers are waiting up to a decade just to hook new AI data centers to the traditional grid, ex-Tesla engineers are bypassing the system entirely.

In this episode, Casey, founder of Voxel Energy, breaks down how they are deploying independent, solar-and-battery-powered data centers in just 150 days. By utilizing a first-principles, 100% DC microgrid architecture and repurposing salvaged Tesla electric vehicle batteries, Voxel isn't just circumventing the grid; they're turning data centers from massive liabilities into grid-stabilizing assets.

Tune in to hear how the AI boom might accidentally solve America's clean energy transition.

What you will learn:

• Why a 10MW data center faces a 7-to-10-year wait time on the West Coast, and how to slash it to 150 days.
• The architectural secret behind a 100% DC microgrid and how it yields up to 30% in energy savings.
• Why Nvidia officially mandates on-site batteries to protect hardware from millisecond utilization spikes.
• How Voxel Energy leverages a arbitrage loop using repurposed Tesla Model 3 and Y batteries.
• Insider lessons from Elon Musk’s 2018 "Model 3 Production Hell" and what it takes to build an execution-first deep tech company.
