Investor Builds $1.7 Million SaaS Without Writing Code – Thanks to AI & Replit
When we hear “startup founder,” we usually imagine a coder glued to a laptop, cracking complex algorithms. But what if we told you an investor built a $1.7 million SaaS product — without knowing how to code?
Meet Brad Lindenberg, co-founder of Quadpay and current investment firm executive. In just 8 weeks, and with $1,500 worth of AI tokens, he developed Biography Studio AI — a platform that allows users to create full-length biographies from voice prompts.
“I’ve never written code before. I used AI tools like Replit, Stripe, OpenAI, and ElevenLabs. It was a steep learning curve — but totally worth it,” said Brad on X.
What Is Biography Studio AI?
This innovative SaaS tool lets anyone record their memories through voice, then automatically generates:
-
A written biography
-
An audiobook
-
A podcast version — all in the user’s voice
Users can try it for free, and for just $119, they unlock unlimited chapters and full-book creation. That’s a huge shift from traditional biography writing services, which often cost tens of thousands of dollars.
Built Solo with AI Tools Like Replit
Brad didn’t just use AI for the front end — the entire app was built using Replit’s AI agent, which helped him manage:
-
Replit IDE for development
-
Git for version control (which he learned on the go!)
-
Railway for production deployment
-
Real-time voice AI from OpenAI
-
Stripe for payments
-
ElevenLabs for high-quality audio
Without AI, building this SaaS would have taken a team of 8 developers and nearly a year, according to Replit’s cost estimation.

The Golden Age of AI-Powered Solo Founders
Amjad Masad, CEO of Replit, celebrated the achievement, calling it a sign of the times:
“It’s a golden age of entrepreneurship.”
And he’s not wrong. More creators are launching million-dollar ideas using AI platforms like Replit, Lovable, and GPT-4o without touching a line of code.
In fact, a Brazilian ed-tech company recently built a tool using Lovable and earned $3 million in 48 hours.
Replit’s Explosive Growth Proves the Trend
Replit, the platform used by Brad, recently crossed $100 million in annual recurring revenue (ARR) — up from just $10 million in 2021. As the no-code movement grows stronger, stories like Brad’s will only become more common.
Takeaway for Aspiring Entrepreneurs
If you’re someone with a business idea but no technical background, this is your moment.
-
You don’t need a team of engineers
-
You don’t need a huge budget
-
You just need curiosity and the right AI tools
