Testimonials
Here's what successful business owners and marketers are saying about me
"...Churn rate dropped significantly."
Jaka did our new app dashboard interface for our Wheelio app.
We built a totally new version of the app and needed something
great for our users to engage with it.
Our biggest issue was our app dashboard and the complexity of
it, since we only added new features and it got clustered and too
complicated for our users, which resulted in bigger churn rates
and more support tickets.
After the redesign of the interface, our support team can finally
breathe again and the happiness of our customers multiplied
overnight. Churn rate dropped significantly.
I would 100% recommend Jaka Smid to anyone serious about
their business, he takes your recommendations and wishes to the
next level, adding his personal touch and improving any
experience to the next level. I worked closely with him on almost
every wireframe and he always improved upon my ideas, which
makes him a fantastic guy to work with.

Karlo Bradica
Founder of Wheelio, 7-figure company
"...Our revenue shot up by 65%
immediately."
I hounded Jaka for 4 months before he agreed to take on our redesign. It turns out great designers are busy! But I didn't back down, because I KNEW Jaka was the right person for the job.
And once we got the ball rolling, every single one of his detailed updates and thoughtful emails blew me away. And here's the thing I loved the most: Jaka was always confident in all his decisions, taking a huge load off my shoulders, making sure everything ran smoothly, and delivering a truly incredible product in the end. Can you imagine asking your designer "what do you think, should we go with A or B?" and getting the answer "B, abso-fucking-lutely, 100 percent B, it's a no-brainer because of X, Y and Z" every single time?! That was such an unexpected revelation and an incredible load off my shoulders!
And finally, as a business owner, THIS is what you're probably interested in: It turns out Jaka was confident for a reason!
Jaka's redesign of our entire SaaS website was — by far! — the most important factor in our revenue growing 65% year-over-year in the past 10 months since the redesign. Our business has been successful (by all means) but extremely steady from 2014 through 2019, consistently bringing in about $1.5M per year. After Jaka's redesign in October 2019, our conversion rates / sales / revenue shot up by 65% immediately, and 10 months later (August 2020 vs August 2019) we are still seeing the exact same 65% year-over-year growth.
This is truly INSANE and if I could only ever recommend one person for any business-related thing in the world, it would be Jaka for delivering a redesign that looks great and CONVERTS. Which is all that matters!

About me
So, who’s Jaka?
I stand out from other designers because I’ve actually built
a multi-million dollar design company from scratch.
That’s why I know how important marketing and sales are.
And while most designers only care about the looks, I care
about how things perform.

Before my business grew into a multi-million dolar companythere was a point where I had to do everything myself: design,
UX, copywriting, marketing, advertising, sales, front-end dev, accounting…
This left me with a deep understanding of what profitable businesses really need.
After selling my design company, I'm now able to focus 100%
on what I do best: designing high-converting e-commerce stores
Today I help businesses skyrocket the performance of their websites & apps using evolutionary design.
So, listen! If you
- Are tired of designers trying to sell you their artwork
- Want to increase conversions on your page or app based on proven, data-driven optimizations
- Are looking for a designer who understands business, marketing & sales
