I just built a fully functional SaaS product in three days.
Alone.
No designer. No front-end developer. No back-end engineer. No QA tester.
Just me and a handful of AI tools.
Five years ago, that same project would have taken a team of five people three months to build.
Something fundamental is changing. And if you work in product, design, or engineering—or you're thinking about any of these careers—you need to know what's happening.
Because the lines between these roles? They're disappearing.
The Old World: How Product Management Used to Work
For the past decade, we've explained product management with the same diagram.
Three overlapping circles:
- Technology (Can we build it?)
- User Experience (Do people want it?)
- Business (Will it make money?)
And right in the center, where all three circles meet? That's where the Product Manager lives.
Here's how it worked:
Week 1: You have an idea. You write a detailed specification document.
Week 2-3: You meet with designers. They create mockups and prototypes.
Week 4-8: Engineers review the designs. They start building. Front-end, back-end, databases.
Week 9: QA tests everything. Finds bugs. Engineers fix them.
Week 10-12: You iterate based on feedback. Launch. Celebrate.
Your job? You were the translator. The coordinator. The bridge.
You translated business goals into design requirements. You translated design mockups into engineering tasks. You translated engineering constraints back to stakeholders.
You didn't build the product. You managed the people who did.
And that was fine. That was the job.
Then Something Changed
In 2024, new tools started appearing.
Tools with names like v0, Cursor, Replit, Lovable.
At first, people dismissed them. "Toys," they said. "Not production-ready."
But these tools did something different. They didn't just help designers and engineers work faster.
They let non-designers design. They let non-engineers code.
Suddenly, the boundaries between roles started to blur.
And blur fast.
What These Tools Actually Do
Let me show you with real examples:
Design Tools (v0, Lovable, Replit):
- You type: "Create a modern dashboard with user analytics and dark mode"
- You get: A fully functional, working interface. In minutes.
- No Figma mockups. No hand-off to developers. Just... done.
Coding Tools (Cursor, Codex, Claude Code):
- You describe: "Add user authentication with Google sign-in and save preferences to database"
- You get: Production-quality code. Complete with error handling. Ready to deploy.
- No back-and-forth with engineers. No sprint planning. Just... built.
The gap between thinking about a feature and shipping that feature just collapsed from weeks to hours.
What This Means (And Why It Matters)
Remember that Venn diagram? The one with three circles and the PM in the middle?
It's breaking down.
But here's what's really interesting: It's not just the PM role that's changing.
The circles themselves are collapsing into each other.
Everyone Can Be Everything Now
Think about what's actually happening:
Designers can now write production code (with Cursor and Claude Code). They don't need to hand off to developers. They can build what they design.
Developers can now create polished interfaces (with v0 and Midjourney). They don't need to wait for mockups. They can design what they build.
Product Managers can now do both (with all these tools combined). They don't need to coordinate between teams. They can ship end-to-end.
The three circles aren't just overlapping anymore. They're converging into one role.
Call it Product Maker. Call it Builder. Call it whatever you want.
The point is: You don't need to pick a lane anymore. You can be all three.
This Affects Everyone
If you're a designer who always wanted to build your own products—now you can.
If you're a developer who has strong product instincts—you don't need a PM anymore.
If you're a PM who felt limited by not being able to design or code—that limitation just disappeared.
The question isn't "What role am I?"
The question is "What can I build?"
And the answer is: Whatever you want.
Before, you needed:
- A designer to create the interface
- A front-end developer to build the interface
- A back-end developer to make it work
- A QA tester to make sure it works
Now, with AI tools, one person can do all of that.
Not perfectly. Not at expert level. But good enough to ship.
Good enough to test an idea. Good enough to validate with users. Good enough to prove a concept works.
And that changes everything.
A Real Example: What I Built Last Month
Let me make this concrete.
I wanted to test an idea for a simple project management tool. Something focused, not another bloated enterprise platform.
The old way (what I would have done in 2020):
Weeks 1-2: Write detailed specs. Create user stories. Build wireframes.
Weeks 3-4: Find a designer. Brief them. Review mockups. Iterate.
Weeks 5-12: Find developers. Explain the vision. Build the front-end. Build the back-end. Fix bugs.
Week 13: Launch to a small group. Discover they don't actually want this specific feature set.
Total time: 3 months. Total cost: $15,000-$30,000. People involved: 5-7.
The new way (what I did in 2025):
Day 1, Morning: Used v0 to generate the interface. Tweaked it. Had a working prototype by lunch.
Day 1, Afternoon: Used Cursor to build the back-end. Database setup. User authentication. Done by dinner.
Day 2: Tested with 10 people. Got feedback. Made changes. Live by evening.
Day 3: Deployed. Shared the link.
Total time: 3 days. Total cost: $0 (except tool subscriptions). People involved: Just me.
Same idea. Same validation. 100x faster.
And here's the kicker: When those 10 users said "we actually want X instead of Y," I rebuilt it in one day instead of going back to the team for another sprint.
The Three Types of Product People in 2030
Five years from now, there will be three types of people building products—whether they started as PMs, designers, or developers:
1. The Coordinator (Shrinking)
This person still relies on teams to execute. They write specs, run meetings, manage roadmaps.
They don't learn the new tools. They wait for "the AI trend to pass."
Reality check: It's not passing. And these roles are disappearing fast.
Where they end up: Competing for fewer jobs with more people.
2. The Specialist (Valuable But Narrow)
This person is exceptionally good at one specific thing.
World-class designer. Elite systems architect. Brilliant data scientist.
AI can't touch them. They're top 5% in their field.
Reality check: You have to be really, really good to stay valuable this way. And it takes years.
Where they end up: High-demand, high-salary roles. But fewer of them exist.
3. The Builder (The Future)
This person combines product thinking with AI-powered execution.
They can:
- Design interfaces (with AI assistance)
- Write code (with AI assistance)
- Test products (with AI assistance)
- Ship fast (without waiting for a team)
They're not the best designer. Not the best engineer. But they're fast enough to validate 10 ideas in the time it used to take to validate one.
Reality check: This is where the market is moving. Fast.
Where they end up: More opportunities. More leverage. More impact.
But Wait—What About Quality?
I know what you're thinking.
"Sure, you can build something fast with AI. But is it any good?"
Fair question. Here's the honest answer:
For prototypes and MVPs? Absolutely good enough.
For complex, scaled systems? You'll still need specialists.
But here's the key insight: Most ideas fail. Not because of poor execution. But because they solve the wrong problem.
The ability to test 10 ideas in a month—instead of 1 idea in a year—means you find the right problem to solve faster.
Then, when you've validated it works, you bring in specialists to scale it properly.
The game isn't "build perfect products faster."
The game is "validate ideas faster and fail cheaper."
And at that game, AI-powered PMs are winning.
The Skills That Actually Matter Now
So what skills do you need in this new world?
AI handles the execution. You bring the judgment.
1. Strategic Thinking
What problems should we solve? In what order? Why?
AI can't tell you what matters to your business. You have to know that.
2. User Understanding
What do people actually need? How do they think about this problem?
AI can generate interfaces. But it doesn't know your users like you do.
3. Creative Vision
What should this feel like? What's the right solution here?
AI can execute your vision. But the vision still comes from you.
4. System Design
How do the pieces fit together? What breaks at scale?
AI can build components. You need to see the whole picture.
5. Effective Prompting
How do I get AI to build what I'm imagining?
This is the new skill. Learning to communicate with AI tools effectively.
Think of it like this: AI is your team now. And you're learning to manage that team.
What This Means for Your Career
Let's get practical.
Whether you're a PM, designer, developer, or thinking about any of these paths—here's what you need to know:
If You're Just Starting Out
Good news: You're entering at the perfect time.
You don't have old habits to unlearn. You can build product skills and AI skills at the same time.
What to do:
- Learn product fundamentals (user research, problem definition, prioritization)
- Pick one AI tool and master it (start with v0 or Cursor)
- Build something. Anything. Ship it. Show people.
- Repeat weekly.
In 6 months, you'll have a portfolio of shipped products that most senior PMs can't match.
If You're Already a PM
Reality check: Your coordination skills are depreciating fast.
Meetings and Jira tickets aren't going to cut it anymore.
What to do:
- Pick one side project. Something you've been "meaning to build."
- Use AI tools to build it yourself. This week.
- Ship it. Even if it's rough. Feel what that's like.
- Repeat until building feels as natural as writing specs.
The goal isn't to replace engineers. The goal is to move faster than teams that don't use these tools.
If You're a Designer
Your superpower: You already understand users, aesthetics, and flow.
Now you can build what you design—without waiting for developers.
What to do:
- Pick up Cursor or v0. Start building your designs yourself.
- Ship one portfolio piece that you designed AND coded.
- Add "product strategy" to your skill set (learn prioritization, metrics).
- Position yourself as a designer who ships, not just mocks up.
You're not becoming a developer. You're becoming a designer who doesn't need developers.
If You're a Developer
Your superpower: You can build anything. You understand systems.
Now you can design interfaces and think strategically—without waiting for PMs or designers.
What to do:
- Use v0 or Midjourney to create interfaces for your projects.
- Practice product thinking: What problems matter? Why? For whom?
- Ship something end-to-end that you conceived, designed, and built.
- Position yourself as an engineer who ships products, not just features.
You're not becoming a designer. You're becoming a developer who doesn't need a team.
If You're a Student
You're in the best position of all.
You're learning in a world where these tools already exist. Use them from day one.
What to do:
- For every project, try building it with AI tools first
- Document what you learn
- Share your experiments publicly (blog, LinkedIn, Twitter)
- Build a portfolio before you even graduate
By the time you're job hunting, you'll have shipped more products than candidates with 5 years of experience.
The Timeline: When This Becomes Normal
We're at the tipping point right now.
Early adopters are already building this way. And they're getting noticed.
In 2-3 years, it won't be impressive. It'll be expected.
The question isn't "Will this happen?"
The question is "Will you be ready when it does?"
Your 30-Day Action Plan
Don't overthink this. Just start.
Week 1: Pick One Tool
- Try v0.dev (design and front-end)
- Or Cursor (coding with AI)
- Or Claude (specs, research, planning)
Use it for one real task this week. Not a tutorial. A real thing you need.
(Want a complete playbook of the best tools and how to use them? I've created a cheatsheet that breaks down exactly which tool to use for what, with real examples and prompts. Email me at vaibhav@bloosprout.co.uk and I'll send it over.)
Week 2: Build Something Small
- A landing page for an idea
- A simple tool you've wanted
- A dashboard for personal data
Doesn't matter what it is. Just ship something by Sunday.
Week 3: Ship It Publicly
- Put it live somewhere (Vercel, Netlify, wherever)
- Share the link on LinkedIn or Twitter
- Ask 5 people to try it
The goal isn't perfection. It's reps. You're building the muscle.
Week 4: Do It Again
- Build something bigger
- Use what you learned
- Ship faster this time
By the end of 30 days, you'll have gone from "I read about AI tools" to "I ship products with AI tools."
That's a career-changing shift.
The Uncomfortable Truth
Here's what most people don't want to hear:
The coordination-heavy PM role is dying.
Not because AI is replacing PMs. But because the best PMs are evolving faster than the average ones.
A PM who can build will always beat a PM who can only coordinate.
Not because building is better. But because speed matters more than perfect process.
And speed comes from collapsing the gap between idea and execution.
Three Paths Forward
You have three options:
Path 1: Ignore It
"This is a fad. It'll pass. I'll keep doing what I've always done."
Outcome in 3 years: You're competing for fewer roles with more people. Your skills are less valuable.
Path 2: Become a Specialist
"I'll become world-class at one thing—design, or architecture, or data—and be too good to replace."
Outcome in 3 years: If you make it to the top 10%, you're golden. If you don't, you're stuck.
Path 3: Become a Builder
"I'll learn to use AI tools as force multipliers. I'll build products myself."
Outcome in 3 years: More opportunities. More leverage. More autonomy.
Which path feels right to you?
Why This Is Exciting (Not Scary)
I get it. Change is uncomfortable.
But think about what this actually means:
You don't need permission anymore.
Designers don't need developers to bring their visions to life.
Developers don't need designers to create beautiful interfaces.
PMs don't need teams to validate their ideas.
Everyone can build end-to-end.
You don't need budget approval to test an idea. You don't need to convince a team to prioritize your pet project. You don't need to wait three months to see if your instinct was right.
You can build it yourself. This weekend.
That's not a threat. That's freedom.
The three circles in the Venn diagram? They're not separate anymore. They're converging into you.
The best product managers have always been the ones who could see around corners. Who could spot opportunities others missed.
Now you can prove those instincts in days instead of months.
You can fail faster. Learn faster. Ship faster.
That's the world we're moving into.
And for people who are curious, who love building, who get energized by seeing their ideas come to life?
This is the golden age.
Start Today
You don't need to master everything. You just need to start.
Pick one tool. Build one thing. Ship it.
Then do it again next week.
That's it. That's the whole plan.
The old roles aren't dying. They're converging.
PM. Designer. Developer. These were always artificial boundaries anyway.
Now the boundaries are gone. And the people who embrace that—who become Product Makers instead of staying in their lane—they're the ones who'll shape the next decade.
Your move.
