For a long time, building products was something only engineers could do. If you had an idea, you had to wait for a developer to build it. Prototyping could take weeks or months. Product leaders had to wait. Entrepreneurs had to wait. Teams had to wait.
That world is changing quickly.
I started (vibe) coding again last year after a long gap on Replit, the AI-powered software development platform that allows users to write, build, test, and deploy applications within minutes. When they introduced their builder certification levels, I was roughly at Level 2 (Core Builder) in January’26. In two months, I have moved to Level 4 (Advanced Builder). It feels amazing!
More importantly, I have built a lot of things along the way.
Some examples:
Nira, a math tutoring app inspired by my 7 year old’s learning journey
Agentic customer success platform for a fictional company
My portfolio website – ishangupta.me
Each of these started as a quick prototype. None required a large engineering team to get started.
This is why I believe being a builder is becoming an essential skill today.
A builder is someone who can take an idea and quickly turn it into something working. Not necessarily a polished product, but something real enough to test, iterate and learn from. Product managers, operators, founders, leaders and individual contributors can all benefit from this skill. And partner with the amazing technical partners to make stuff production ready.
Recently, Aakash Gupta shared a great framework on how top product managers use rapid prototyping to move from many ideas to one shippable feature. I found this particularly useful because it shows how fast experimentation can work in practice.
The idea is simple and yet powerful. Build multiple prototypes quickly, test them, eliminate the ones that do not work, and move forward with the strongest idea.
Today, many tools make this possible. The one I personally use and deeply admire is Replit, and it has been a great experience for me. Check it out here.
My advice is simple. Start small. Build something. Experiment.
Whether you are a leader or an individual contributor, the ability to turn ideas into working prototypes quickly is a skill worth developing.
