Are dev agencies dead? 🤔

Steal this startup idea inside

In partnership with

You used to need $10K and a dev team to build your idea.

Now… all you need is 1 prompt.

We’re serious. That’s what we tested this week with a tool called HeyBoss AI—and the results were ridiculous.

In our latest video, we fed HeyBoss a simple request:

“Make a marketing site for a guitar lesson business with booking and payments.”

Frontend, backend, database, everything. Done in under 9 minutes.

The newsletter every professional should be reading

There’s a reason Morning Brew is the gold standard of business news—it’s the easiest and most enjoyable way to stay in the loop on all the headlines impacting your world.

Tech, finance, sales, marketing, and everything in between—we’ve got it all. Just the stuff that matters, served up in a fast, fun read.

Look—over 4 million professionals start their day with Morning Brew’s daily newsletter, and it only takes 5 minutes to read. Sign up for free and see for yourself!

9 minutes later, we had a fully functional app:

  • Stripe payment flow

  • Multi-step booking form

  • Custom logo and packages

  • User account creation

  • SEO-friendly pages, testimonials, mobile design... all done.

But the craziest part?
You get to watch a team of AI agents build it in real-time, having conversations about UX, database structure, copywriting, and integrations—like a legit dev team. For someone who isn’t super familiar with these processes, it was pretty damn cool to see.

This isn’t a website builder.
This is an AI dev agency in a box.

So… are dev agencies dead?

Not exactly. But the things are definitely changing. If you’ve read any of our past newsletters, vibe coding is in full force.

If you’re a solo builder, this is your moment.
If you’re a scrappy founder with ideas and hustle, AI tools like HeyBoss shift the balance in your favor.

You no longer need to hire out to validate a product.
You don’t need to manage a team to launch something good.

You just need the right prompt—and a plan to ship.

Steal this startup idea:

Saw this tweet from Manny and had to share it:

  1. Use a dev sandbox to quickly rebuild local business websites & make them better

  2. Reach out to the owner with a working version

  3. Offer to hand it off: “Hey, I made this for you. Want it for X amount?” or maintain it for them monthly

Immediate value. Instant pitch.

You could do the same with HeyBoss.

Spin up a polished site for a local gym, yoga studio, or music teacher. Add bookings. Add payments. Then reach out with:
“Hey, I made this for you.”

It’s not just a project. It’s a business model.

This is where the future is headed.

Might as well build something on the way there.
