Hi Ivaylo! What's your background, and what are you currently working on?
Hey there!
My name is Ivaylo (Ivo) Kalburdzhiev, 31, living in Sofia, Bulgaria and in 2012 I spent 3 years of my life and $50,000 building something nobody wanted!
Sounds familiar?
KOLOS was the ‘world’s first’ iPad racing wheel that never was. You clamp it to any table, insert your 9.7” iPad and start playing your favorite tilt games instead of holding the tablet in the air.

I was the ‘genius’ (and CEO) behind the idea, and, as with any startup, I was doing a little bit of everything - marketing, business development, investor relations, customer support, prototyping, etc.
What motivated you to start Kolos?
Great question and one that many founders probably do not ask themselves but jump straight into building a business.
My motive?
Just the idea of having a startup. The idea that I was ‘brilliant’, and smart, and I was going to build something new and cool, and show it for the world to see.
As a student, and working as a customer support rep at the time, I always knew I was going to be an entrepreneur, so there was my chance to ‘prove it’.
Yet still, I had:
Zero previous knowledge of building startups and raising capital.
Zero-knowledge of mobile gaming, hardware, and prototyping.
Just a big (read: useless) diploma in Marketing.
Heck, I didn’t even own an iPad. I bought one after I came up with the idea.
'Brilliant', ey?
How did you build it?
Short answer? The wrong way.
Instead of using DIY materials like wood or off-the-shelf parts of gaming accessories to test if the idea was even worth it, I went straight to the bank, took a huge loan and then paid industrial designers to start working on the 3D models.
After those were done, I paid literally thousands of dollars for super expensive prototyping online (Shapeways.com) since the models were big and bulky to create.
I also paid someone to write my own business plan, I used the loan money to fix my old car, and essentially found numerous ways to not spend the money wisely.
At the time I was doing my day job and studying, so at some point after 2 years in development, I decided to launch it on Indiegogo.com.
Naturally, at around $100 a piece, no one bought it. I also had little idea of how to run a crowdfunding campaign.
I still didn’t give up.
Later, after countless rejections from accelerators and investors, me and my co-founder got accepted into the Buildit hardware accelerator where we spent 3 months and another $20,000 on the business.
Shortly after, we finally had to find a way to launch it as we were running out of money.
In early 2015, a Kickstarter campaign followed where we raised $4,000 and had to shut down the campaign shortly after.
