1. Build a home security system ($840K/year)
Nate Clark from Orlando, FL, USA started Konnected Inc. over 3 years ago, a home security system.
- Revenue: $70,000/ month
- Founders: 1
- Employees: 4
- Location: Orlando, FL, USA
I strongly believe in open systems developed with service providers that offer the freedom of choice for consumers. I am very much an ‘accidental founder’ in the sense that when I first developed Konnected, I was just trying to solve an issue with my traditional home security system and transition it to a smart system.
As I was preparing to go on a family vacation, I learned of a few neighbors reporting break-ins, which prompted my concerns about not being able to fully monitor my home’s security remotely.
During my trip, I couldn’t help but wonder if there was a way for me to connect the sensors that I had in my home to a SmartThings device so that I could keep track of my home while I was gone. This put the wheels in motion for a new software project for me.
2. Become an author ($168K/year)
Nick Thacker from Colorado, USA started Nick Thacker about 4 years ago, a author.
- Revenue: $14,000/ month
- Founders: 1
- Employees: 1
- Location: Colorado, USA
I’ve always been a fanatic reader, specifically in the thriller genre. I discovered Dan Brown as a kid, then James Rollins, and I’ve always love action movies that combine adrenaline and history (think National Treasure, Indiana Jones, etc.).
I decided to write a book (my first was called The Golden Crystal, and it has been re-launched as The Atlantis Stone) when my grandfather passed away. He had always been a strong positive influence in my life, and he, my dad, and I often swapped paperbacks we liked. That first book was intended as a gift for my dad for Christmas, and it was going to be the only one I ever wrote -- just to see if I could do it.
I had no idea what I was doing (arguably, I still don’t…). I just thought it would be fun to combine technology with the discovery of Atlantis… in some way. When I got started, I was naive enough to think that books simply happen, but the book very quickly got the best of me. I took a six-month break and consumed as much as I could on the subject of the craft of writing fiction. I’d never really written anything before, so it was an eye-opening experience to learn about structure, plot tropes, character development, and everything else that goes into a good, cohesive story.
3. Start a crime scene cleanup business ($33.6M/year)
Nick-Anthony Zamucen from Greenwood Village, Colorado, USA started Bio-One almost 13 years ago, a crime scene cleanup business.
- Revenue: $2,800,000/ month
- Founders: 1
- Employees: 7
- Location: Greenwood Village, Colorado, USA
I started Bio-One Inc. over two decades ago.
Bio-One is the nation's leader in Crime & Trauma Scene Cleaning with over 90 franchised to date and growing. Bio-One isn’t like any other business you get into, it’s not all about profit.
Let me explain a bit more. When a suicide, homicide or an undiscovered dead body is found, there are many people who get called to the incident. The police, coroner/medical examiner, fire department, detectives and the last responders are companies like mine, Bio-One the crime scene cleaners. Not all scenes we clean are crimes, but the term crime scene cleaner gives some mental picture of what gets done. We clean and remediate what is commonly left behind from EMT’s, police, fire departments and coroners to name a few.
