For decades, venture capital revolved around one word: moat.

Proprietary technology. Network effects. Switching costs. Regulatory barriers. Anything that could keep competitors out while a startup scaled. Buffett built an empire on the concept. Every pitch deck had a slide for it. Every partner meeting came back to the same question: What's the moat?

It's time to retire the question.

The moat, as we knew it, is gone.

This really crystallized for me last week in a conversation with my friend and mentor Ullas Naik, Founder and General Partner of Streamlined Ventures. Ullas Naik is a solo GP behind more than 200 portfolio companies including DoorDash, AppLovin, and Rappi. He put it bluntly: the era of sustainable competitive advantages for startups is over. The winners won't be the companies with the thickest walls. They'll be the companies that can run the fastest.

For my partner Stefan Krause and me, this is powerful validation of the thesis we set when we founded Mavka Ventures. We've said from the start that speed and non-obvious market selection would define the next generation of venture winners.

Ullas is exactly right. Here's why.

Software Moats Evaporated

In 2025, AI startups captured 65.6% of all U.S. venture capital. Up from 46.4% the year before. That flood of capital didn't create defensibility. It destroyed it.

AI wrappers and application-layer tools built on commoditized foundation models are shutting down at accelerating rates. They have no lasting differentiation. When anyone can build a functional product on top of the same APIs in a weekend, your six-month head start isn't a moat. It's a head fake.

The cycle time for software replication has collapsed to near zero. Open-source models proliferate. Dev tools are so abstracted that a competent engineer can rebuild most SaaS products in weeks. Vertical expertise that once took years to develop can now be replicated by AI in months.

What used to be a two-year technical advantage is now a two-sprint sprint.

Hardware Is Next

If software moats have evaporated, hardware moats are melting fast.

We see this up close at Mavka. The humanoid robotics space, one of our core investment themes, saw $1.2 billion raised just this month. Physical AI is attracting enormous capital, with nearly $2 billion raised by U.S. startups in 2025 alone.

But all that money hasn't created differentiation. It's done the opposite. Proprietary hardware designs, custom actuators, novel form factors: these are becoming table stakes. Contract manufacturers in Shenzhen can replicate mechanical designs faster than ever. Sensor costs keep falling. What was exotic robotics hardware three years ago is a reference design today.

Same story in autonomous vehicles, data center infrastructure, and energy systems. Capital abundance plus global supply chains plus open-source toolchains are commoditizing atoms almost as fast as bits.

Big Tech Learned to Move Fast

There was a time when startups could count on big companies being slow. Too bureaucratic, too distracted by their core businesses, too clumsy to pivot.

That time is over.

Today's tech giants are sophisticated at spotting emerging markets and attacking them with overwhelming resources. OpenAI, Anthropic, and others are pushing into the application layer. Entire categories of venture-backed companies face the risk of vanishing overnight. Google, Microsoft, Amazon, and Apple don't wait for a market to mature before entering. They build competing products the moment a category shows traction.

The old playbook assumed a window of inattention that no longer exists. Find a niche, build a product, grow into adjacencies before the giants notice. That window closed. Big tech now has venture-scale speed with Fortune 10 resources.

And here's the twist: the FTC's aggressive posture on acquisitions has actually made things worse for startups. Rather than acquiring promising companies (which at least provided exits), incumbents now just build competing products internally. Startups end up with neither a buyer nor breathing room.

The Crowded Arena

Then there's the sheer density of competition.

In virtually every meaningful category, from vertical AI to developer tools to robotics to fintech to climate tech, there are now dozens of well-funded competitors going after the same opportunity. B2B SaaS shutdowns rose from 5.2% to 7.7% of all closures in 2025. When 40,000 AI startups are chasing the same enterprise budgets, being good isn't good enough.

CIOs are already pushing back on AI vendor proliferation, consolidating their toolsets and spending around established players.

This isn't cyclical. It's structural. The barriers to starting a company have fallen so far that the supply of startups now permanently outpaces the market's ability to absorb them.

So What Wins?

If moats are dead and competition is everywhere and big tech is breathing down your neck, what's the path?

Speed.

Velocity of execution. The ability to learn faster, iterate faster, and capture a market before it's legible to the consensus. As Ullas puts it, the companies that generate outsized returns are the ones that move with such relentless pace that competitors are always reacting, never leading.

But speed alone isn't enough. Speed in a crowded, obvious market just means you're running fast in a stampede.

The real alpha, for founders and investors alike, is at the intersection of speed and non-obvious insight. Building a generationally important company in 2026 comes down to three things:

Find a multi-billion dollar market that is non-obvious. The best opportunities are the ones most investors scroll past because they don't fit a clean category or the timing seems off. If every VC at a dinner party is excited about your space, you're already too late.

Have deep, earned insights that others lack. Domain expertise matters more than ever. Not the kind you get from reading market reports. The kind that comes from years of operating, building, and failing in a specific problem space. Your insight is your only real edge.

Execute with ferocious speed. Once you've found the opportunity and validated the insight, there is no substitute for velocity. Ship fast, learn fast, compound fast. In a world without moats, your speed is your moat. It's just a temporary one you have to rebuild every single day.

This is the framework we apply at Mavka Ventures as we evaluate embodied AI and frontier technology opportunities. We're not looking for impenetrable fortresses. We're looking for founders who see what others don't and move faster than anyone thought possible.

The moat is dead. The race is everything.
