2026 could be the best entrepreneurial window for our generation

I haven't been this inspired by an article in a long time.
Greg Isenberg, 36, serial entrepreneur, has sold 3 companies, and mentored teams from seed stage to unicorn. He says:
2026 will be the best startup opportunity in the past 30 years.
At first, I thought it was clickbait.
But after reading his 20 reasons, I admit—I'm convinced.

The most disruptive point is that the cost structure is being directly shattered.
In the past, building an enterprise SaaS,
30 engineers, hundreds of thousands of dollars in costs, was the starting point.
Now?
One person + a Claude Code subscription is enough.
Software that used to cost $500,000 to develop,
can now be almost replicated for a fraction of that.
What does this mean?
It means a large number of traditional SaaS companies, relying on feature stacking + high subscription fees,
are being gradually eaten away by small teams, ultra-vertical, extremely low-cost products.

Then there's the qualitative change in business models.
In the past, selling software meant selling features, selling subscriptions:
Whether the customer uses it or not was their own business.
Now, it's different.
AI Agents directly complete the “work.”
Entrepreneurs no longer sell tools, but sell results.
You don't need to explain features,
just say one sentence:
👉 I’ll handle this for you, and if I can't, I won't charge.

And then there's the lowered barrier to entry.
A previous MVP often took months.
Now, with tools like Lovable, Rork, you can prototype in days.
Greg says, the current pace has become:
one MVP per week.
This will bring a terrifying change:
small teams can run multiple products simultaneously,
and whichever succeeds, they go all-in on.
Entrepreneurship is no longer about “betting big,”
but more like portfolio investing.

There's also a judgment I strongly agree with:
Coding is no longer a bottleneck.
In the past, our biggest complaints were:
not enough engineers, slow development, scarce technical resources.
What is truly scarce now?
Deep understanding of business processes,
the tacit knowledge only veterans in the industry know.
Code has become cheaper,
but cognition, taste, industry insights are becoming more valuable.
So the next wave of true winners will likely be:
👉 former operations, former sales, former product managers who understand business,
👉 those who can encode their decade of experience directly into Agents.
This is the real moat.

Speaking of moats, Greg posed a very harsh question:
If AI can replicate a $500,000 software for just $20 a month,
where exactly is your barrier?
He only gave four answers:
Distribution, customer relationships, branding, data.
Technology itself is rapidly depreciating.
What’s truly valuable is:

Do users know you

Do they trust you

Can they leave you

So he said something very realistic:
This is the best era for designers and marketers.

And the final sentence he said, I think, is the key takeaway:

We are in an extremely rare window,
where multiple technological paradigms are changing simultaneously,
small teams can suddenly do things that were previously impossible.

But—
This window won't stay open forever.
Markets will adapt,
giants will respond,
opportunities will close.
The essence of this window is never “more opportunities,”
but “very little time to hesitate.”
If you're waiting for a “more stable” moment—
you might have already missed it.
