I'm an entrepreneur that turns ideas into startups. I currently run Thinkbox where I help others do the same and Studiotime. Previous two startups were acquired. I'm also an angel investor in 15+ startups that have raised $110M+ and a limited partner in two funds (pre-seed fund and crypto asset fund). I love sharing what I'm learning and working on.


Yo, I'm Mike Williams or you might know me as Yoroomie.

I'm a serial entrepreneur that builds, helps build, and invests in startups. I started Thinkbox, a startup studio. We build our own startups, help others build startups, and make early stage investments (15+ startups that have raised over $110M).

I'm also the founder of Studiotime, which is the first company launched out of Thinkbox and the largest online community of music studios in the world. It's been called the "Airbnb of music studios" and has been featured in VICE, Forbes, BBC, and other press in 35+ countries. I share the story of how I cancelled dinner, built it in an evening, and launched it here.

I also built and launched Yoroomie App, which was acquired within six months. This was our first acquisition for a Thinkbox company. I've written in-depth about how we built the app in 30 days, growth hacks we used to scale it, and then what we learned from it being acquired here.

Prior to this, I was the founder and CEO of Codeity, a hiring platform that was scaled to 500+ companies that used it to hire developers. It was acquired in 2015 by Angelhack (press release on that here).

I love taking ideas to validated startups and am obsessed with marketplaces and blockchain/crypto-assets (in addition to startups). I share everything I've learned along the way and am working on. Sometimes I also contribute to Huffington Post, freeCodeCamp, Hacker Noon, and a few other publications. In my spare time I also mentor with the Founders Institute (startup accelerator program) and help the companies I've invested in.

Tools To Quickly Build & Validate Your MVP

Sharetribe- Create an MVP for a spaces, services, or goods marketplace (Airbnb, Task Rabbit, Etsy, etc) within minutes. Sharetribe is what I used to build the Studiotime MVP with.

Instapage- Quickly create a landing page, website, or lead generation page in minutes using templates that can be easily modified without coding.

Zapier- Easily integrate and automate your workflows, tasks, and tool stack that you use for to build your MVP or even automate operations. I used this to automate Studiotime and it allows me to spend about an hour a week on it.

Chatfuel- Quickly create a Facebook Messenger chatbot without coding. This was what I built Art Chatbot on, tested, and launched within hours.
