Building things

Kevin Wimer

Entrepreneur, builder, and angel investor. For more than two decades, I’ve turned curiosity into products, companies, and hard-earned lessons—while staying grounded as a husband and father.

Open to opportunities

The next thing is still unwritten.

I’m open to starting something from zero, joining something already in motion, or collaborating on a promising idea. I’m equally at home building independently or alongside a sharp, curious team. I’m waiting for the problem, people, or idea I can’t stop thinking about.

A few defining chapters—companies built, risks taken, and lessons that still shape how I work today.

01
Rivalry.com · Co-founder, CMO & COO 2018–2025

Helped take an esports startup from launch to the public markets.

Led marketing and operations as Rivalry grew beyond 150 people, generated tens of millions in revenue, and became a publicly listed company. The financial outcome wasn’t the one I hoped for, but the scale, complexity, and hard-earned lessons reshaped how I build.

150+ people Tens of millions in revenue Publicly listed
02
JamPlay.com · Co-founder 2006–2018

Bootstrapped an idea into a multimillion-dollar business.

Helped build JamPlay from its first line of code and first customer, leading development and marketing as the online education company grew from zero revenue into a profitable, multimillion-dollar business. I later exited by selling my ownership stake.

03
Professional Gamer 1998–2014

Turned competitive gaming into a passport.

Ranked top 10 in Red Alert and Unreal Tournament, reached Rank S in StarCraft, competed internationally, and later played StarCraft II in Korea. Sponsors paid me to travel the world, and tournament finishes brought in thousands in prize money.

Yikers.com · Founder 1998–2005

Built in a childhood bedroom. Sold during the first wave of viral video.

Created Yikers.com from my parents’ house at 17 and grew it into an early video-entertainment destination—before YouTube made online video mainstream. The eventual sale gave me a mid-six-figure exit.

05
The Early Internet Era Started 1998

Learned the internet by building on it—before there was a playbook.

At 14, I started making joke sites, video-game cheat databases, and yes—emulator and ROM communities. Built in Notepad over dial-up with almost no supervision, those projects generated hundreds of thousands in profit and became the foundation for everything that followed.
