A QUARTER OF STARTUPS IN YC'S CURRENT COHORT HAVE CODEBASES THAT ARE ALMOST ENTIRELY AI-GENERATED

A quarter of Y Combinator's W25 startups used AI to generate 95% of their codebases. This trend highlights the rise of "vibe coding," where developers rely on LLMs to create code while needing classical coding skills for debugging and quality checks. Startups such as Bolt.new and Magic have received significant funding, underscoring growing interest in AI-powered coding solutions.

REVISITING COMPETITIVE MOATS

Placing all your bets on a single standout feature or a massive R&D budget isn't a safe long-term strategy. In fast-moving markets, real defensibility comes from constant iteration and genuine user focus. A moat isn't built once—it's a habit of out-learning and out-improving the competition.

MAKE SOMETHING HEAVY

Quick posts and viral hits might be exhilarating, but they don't always leave a lasting mark. Founders and creators should invest in deep, substantial projects—a product with real staying power or a well-researched piece of content—that can resonate far beyond a short burst of online buzz.

THE END OF YC

When coding becomes cheap and easy, do engineer-founders still have the biggest edge? With AI lowering the barrier to building MVPs, deep domain expertise could trump raw coding power. Accelerators might shift their focus to founders who truly grasp a market's pain points—because assembling a prototype isn't the hard part anymore. It's understanding what's worth building in the first place.

WILL AI HAVE A TASTE ALL OF ITS OWN?

There's a growing sense that AI might eventually develop creative preferences that differ from human sensibilities. Early signs show it praises its own AI-written poetry or text in ways humans might find off-base. While AI isn't matching human literary brilliance just yet, this “AI taste” could lead to new forms of expression and markets we haven't imagined. Engaging with these shifts now might reveal novel opportunities in art and writing.

HOW DATA-DRIVEN CAN VC INVESTING BE?

Inspired by the rigor of public-market quants, some VCs are starting to apply advanced analytics to spot promising startups. With more data on private companies, they can scale their coverage beyond the typical few hundred deals and do deeper checks than the traditional “pattern matching” approach. For entrepreneurs, it means you may face more precise questions around growth signals and market data—and new ways of standing out if your metrics are strong.

DO GROSS MARGINS MATTER?

Yes, and here's why: gross margin sets the upper limit for how profitable your startup can eventually become. Early on, you might focus more on growth than on unit economics, but if it's always expensive to deliver your product, profitability remains out of reach. For AI-heavy solutions, shifting compute costs can make margins unpredictable. Savvy founders calculate how each new technology change impacts the direct cost of offering their service.

WHERE ARE THE 2021 UNICORNS TODAY? 60% ARE STUCK IN LIMBO, PER CARTA

A blunt reality check: many startups that soared to $1B valuations in 2021 haven't raised another round, sold, or shut down. They remain “unicorns” in name only—without big follow-on funding or traction. Some were acquired or got new investments, but most are stuck. This reminds today's founders that easy money doesn't last, and that real growth and solid business results matter more than inflated headlines.

WHY THE BEST LEADERS ARE PARANOID ABOUT BASIC EXECUTION

Even the smartest strategies can fail if basic tasks slip through the cracks. It's easy to forget a follow-up or ignore a customer question in the rush of daily work. However, small misses add up fast, eroding trust. Top operators build systems so that routine items—like callbacks, contract renewals, and support tickets—never get lost. It's not glamorous, but it's how consistent leaders win in the long run.

“I SCRATCHED MY OWN ITCH” ISN'T GOOD ENOUGH

Fixing a problem you personally have doesn't guarantee a winning startup. Just because you felt the pain doesn't mean there's a big, urgent market. The real test is making sure many customers share that pain, will pay for the solution, and see it as a must-have. Many founders miss this reality check and stay stuck in a personal bubble.
