About Me
I've spent my career at the intersection of technology and creativity—building companies that connect people and making music that tells stories.
I'm Selçuk—a serial entrepreneur, investor, and songwriter based in New York. Most recently, I founded Bunch, a group video chat app for playing games together, used by over 10 million players.
Before Bunch, I founded and sold two adtech companies: Manifest (acquired by Rakuten) and Boostable (acquired by Metric Collective). I've been a Venture Partner at 500 Startups and co-founded Nomadic Mentors, a nonprofit bringing elite startup mentors to emerging tech hubs.
When I'm not building companies, I write and record music under the name ATLI. You can listen to my debut album, Heart Sized Revolutions.

Get in touch →The Pivot Pyramid
A framework I created for startup experimentation, referenced in publications like VentureBeat and Founder Institute.
After building my second company, I became an investor at 500 Startups. Working with dozens of founders, I noticed the same pattern: teams struggling to decide what to change when things weren't working. In 2016, I created the Pivot Pyramid to give them a framework.
The framework organizes a startup into five layers—Customers, Problem, Solution, Technology, and Growth. The key insight: the lower you pivot, the more everything above it changes. A customer pivot reshapes your entire business. A growth pivot? Just a new channel.

I've been awarded 5 US patents in social gaming and adtech, cited by Google, Meta, Salesforce, Nike, and ByteDance.

Heart Sized Revolutions
My debut album as ATLI — raw, honest songs about what we build and what we break.
Music has always been my parallel path. As ATLI, I write songs that explore the tension between ambition and vulnerability—the anthemic and the intimate.
"Heart Sized Revolutions" is a collection of 12 tracks spanning indie rock, synth pop, and brit rock. It's about small revolutions—the kind that starts in the chest and radiates outward.
