CEO @ Contrast: Boosting UX performance for our clients with 'The Hero Framework", and our top notch UI/UX Design Services🌟 New: Boosting CX performance with AI ⭐️ Founder, Affirmations.co. 🌕 Ex: Fiverr, Similarweb.

I build companies, frameworks, and myself.
15 years of deep product & UX work and building brands. 
Today with my two companies I help CEOs and founders gain clarity - either on their product (Contrast UX), or on their personal brand (Gravity).

Previously: First designer at Fiverr, 7 years mentoring at Google. 

Writing about: entrepreneurship, UX, clarity, leadership, building a personal brand, and the inner work behind building businesses.

⭐ CONTRAST UX:
As CEO and Strategic UX Advisor at Contrast, I lead a UI/UX design agency that partners with standout startups globally. 
Our unique UX and UI frameworks with AI are set up in a way that - once implemented in digital products - sparks EMOTIONS. This has proven to boost engagement, retention, and brand awareness for our clients. 

TL;DR: We use UX methods with AI to analyze Emotional Triggers, then design pixel perfect designs using our specific framework that sparks human dopamine triggers. That’s why our designs WORK.


Who am I: My journey spans across 17 years of working with startups. From being Fiverr's first design hire, to mentoring at Google Launchpad (and being trained by them on their methods), co-founding my own startup - Tapdog, later to be acquired by Similarweb where I became Design Director, and learning from design leaders at top tech firms such as Airbnb, Facebook, Google, Apple, Etsy, Intercom, and more. 

I’ve spent the last 9 years distilling this experience into methodologies that empower startups and proving them out in the open market.

Our unique frameworks at Contrast are:
+ "The Hero Framework" for UX - fuses storytelling with Google’s Design Sprint methodology
+ "Design Triggers" for UI - built on neuroscience-based UI design tactics

💫 GRAVITY
At Gravity - we help founders build their personal brand and create content that pull ICPs and opportunities toward them. 

Check out my "featured" section for ways to reach out.

Writing a book is the most traditional thing I’ve ever done, but how we’re doing it is really cutting edge, it's anything but traditional!

For the last two months, Gal Agadi and I have been deep in a collaborative GPT project folder, workshopping chapters and documenting every story we’ve ever shared. It started as a way to collect our thoughts, but it turned into something much more powerful.

We built custom AI tools to analyze years of our past writing. These tools didn't just organize the data, they distilled our exact tone of voice into a professional writing guideline for both English and Hebrew.

Now, we’re writing the book in both languages simultaneously.

It’s a strange feeling. We are using cutting-edge technology to achieve the most traditional thing imaginable: writing a book. The AI isn't replacing our voices, it's ensuring they stay consistent as we scale our message.

I’m incredibly excited about the world we live in. Being savvy enough to build tools that serve your creative vision is a superpower. It allows you to focus on the soul of the work while the system handles the heavy lifting.

Entrepreneurship is a spiritual journey, and technology is finally catching up to help us manifest our vision faster than ever.

Building Contrast & Gravity | Helping Founders Gain Clarity on their Product and Brands | Book Coming 2026 🌕 Ex: Fiverr, Similarweb, Mentor @ Google Launchpad

9 years ago I was a confused entrepreneur. 
No vision. No roadmap. Lost. I'm now writing a book I wish I had back then. 

The new book is called 'Gravity - How to Build & Become a Magnetic Personal Brand.'

Building a personal brand is tricky. 

But Gal Agadi and I know what is 100% true - 
you better do it aligned to your vision and to yourself. 
not by chasing likes or engagement. 

We believe you should chase the best version of yourself instead. 

Become the brand.
Document the process.

When you focus on your own growth, the brand follows naturally. 
You build an authentic way of attracting people. 

In our upcoming book, we’re sharing the raw stories that exposed this to us.

- How I grew two successful blogs as side projects that became my main business and generated millions of views and podcast downloads.
- How Gal grew his LinkedIn into what it is today with over 4M impressions.
and more.

We're writing the playbook for how to build a personal brand and business that "broadcasts" itself.

It’s a mix of tactics, strategy, but most importantly - our core philosophy. 

We're also working on our new SaaS that our clients are already starting to use (the Gravity app) , and I can't wait to share it with everyone here soon.

All this while I'm still CEOing Contrast - UI/UX Design Agency and scaling our frameworks and work methods with our amazing clients there.  

If you’ve been following my journey for years - 
no matter what project I’m on -
thank you so much! 

If we just connected - 
thanks for reading this and being a part of my journey now.

Will keep sharing as we go along, and try to keep documenting here!

Thank you Chris Ducker , Chloe Ducker and Youpreneur® Press! We're super excited to be working on this!

For years, I told myself I wasn't successful enough to write a book.

The imposter syndrome was loud. 

Every time I thought about starting, I’d look for reasons why I wasn’t qualified yet. 

I even started a process with a book coach four years ago and walked away because I just didn’t feel "ready".

This week, everything changed.

My business partner and best friend, Gal Agadi, and I finally stopped waiting for permission. 

We booked an off-the-grid space, disconnected from the noise, and started writing our first book.

If you’re waiting to feel 100% ready to do something that pushes you out of your comfort zone, you’ll be waiting forever. 
Whether it’s writing a book, 
pitching for that talk at a conference,
scaling your business, 
or building a personal brand. 

The external validation you’re seeking doesn't exist.

You are already qualified to tell your story. 

You don’t need a specific revenue milestone or a certain title to be an inspiration.

Entrepreneurship is a spiritual journey of gaining clarity, and I learned that clarity only comes through the act of doing.

Stop waiting for someone else to tell you it’s your turn. Just go for it.
