Why I Created Trainn (by Sam Roth)
As a busy parent of two, I know how challenging it can be to find the right activities for kids and for yourself. My goal with Trainn is to make booking kids' activities, after-school programs, and adult classes as easy as ordering dinner online and eventually support people around the world.

Trainn’s mission is to build stronger communities through fitness, creativity, and play. We help families and adults easily discover and book activities — from kids’ soccer to outdoor yoga — all in one simple platform.

The Problems I Saw
I created Trainn after running into two frustrating problems at the same time:
I wanted to work out outdoors in San Francisco, but couldn’t easily find or book a local class.
My son wanted to play soccer, but we missed the sign-up for the local league and were concerned about a 10-week commitment due to travel plans.
I realized there wasn’t a platform that made it simple for parents and adults to:
Quickly discover classes nearby
Avoid long-term commitments if they just want to try something new
Book in just a few clicks

Why I Built Trainn
Beyond solving a personal problem, I’ve always been passionate about teaching and building communities. After my MBA at UC Berkeley, I knew I wanted to launch something meaningful at some point in my life. Now is the right moment for me to do so.
With the rise of AI vibe coding tools, I built the Trainn MVP myself with Replit, tested it with family and friends, and now I’m excited to launch it publicly in San Francisco.
