Built from the gym floor.

I'm Storm Kolmodin. Licensed personal trainer, agile project manager, and developer. I build websites for gyms, clubs, and coaches. Not because I found a niche, but because it's the world I come from.

Stormie Performance is a small studio with a simple promise: you'll work directly with the person building your site. No middlemen. No handovers. No surprises.

— Storm

i. Licensed Personal Trainer

Certified since 2018 and further educated at the Swedish School of Sport and Health Sciences (GIH). I understand what motivates people to take the first step and what keeps them coming back.

ii. Agile Project Manager & Developer

Trained at Futuregames and Stockholm University. Projects delivered with clear communication, structured workflows and attention to detail.

iii. Former Gym Manager & Fitness Instructor

Working in fitness since 2017. From memberships and schedules to coaching and daily operations, I understand how gyms actually run.

iv. Built for Fitness Only

I don't build websites for restaurants or law firms. Every project is created for gyms, martial arts clubs and coaches. Having worked in the fitness industry since 2017 as a personal trainer, fitness instructor, gym manager, and coach, I understand the businesses I build for.

Built for the fitness industry. Nothing else.

Three steps. No surprises.

1

We talk

Every club, coach and business is different. We start by understanding your goals, your clients and the role the website should play in the business.

Built together

Whenever possible, I review your existing website, social media and public material before we meet. That gives us something concrete to discuss from the start. From there, we test ideas, make adjustments and keep improving the site together.

Live on your domain

The site launches on your address with forms, booking and everything connected. From day one you update schedules, news and prices yourself, and I handle the operations behind the scenes.

Easy for you.
Handled by me.

Your domain is yours. Your content is yours. Updating it is something you do yourself, in a regular spreadsheet. Change the schedule, post news, adjust prices in the time it takes to make a coffee. No CMS logins. No thick manuals.

Everything you don't want to think about, like hosting, security, backups and updates, I take care of for a flat monthly fee. Lower than what a template platform charges.
