How much blood have you wasted? How many family days have you sacrified and still got not enough sales?

Marketing f**ckin sucks if it doesn’t work! You’ve done everything you could for months but still nothing seems to work the way it was supposed to.

Fb ads, Google ads, Tiktok, Instagram, cold emails, Twitter… 

Broken promises, debt, depression. We’ve all been there…

We miss the fact that we sell to real human beings, with feelings, desires, dreams, wants, and needs.

It’s absurd to think people are logical!

Our brains evolved through millions of years of evolution with the single goal – to survive. Yet we still insist to market our products in logical terms…”

– Rory Sutherland, Vice Chairman of Ogilvy UK

The real WHY of why people buy things is often hidden deep in psychology in the unconscious parts of our brains.

Not knowing what makes people tick and buy makes companies lose millions, every day!

We tend to do the “logical” things, without even realizing they work against us. It happens to every company! Even the big ones:

  • Wikipedia probably lost hundreds of millions of dollars, because they weren’t aware of “Negative Social Proof”.

    They framed their message asking for donations admitting that only a fraction of readers donate money to them.

    They could’ve expected 400+% bigger returns if they framed their message pointing to the fact that millions of users already have donated – which is also true.

People don’t buy products

They buy emotions

Things in marketing that don’t make sense, yet work:

  • Chocolate tastes sweeter when in a circle than in squares
  • Painkillers are more effective when you tell people they’re more expensive
  • Wine tastes better when poured from a heavier bottle
  • An increase in pricing increases the demand – in some cases

Yes, we agree, human perception is crazy…

Wouldn’t it be easier for you, knowing what makes people tick to make your customers happy and earn the hard cash along the way?!

  • Why some products are so charming it feels offensive not to buy them, while others make you wanna go back to your ex?
  • Why do some services feel like they are your perfect match, while others make you lose your self-respect?

FAQ – Frequently Asked Questions

What’s the difference between Brainiac and Unicorn Warrior? 

Brainiac, in my opinion, is a collection of fundamental, strategic principles every founder, marketer, designer, and copywriter should be aware of. It’s like with driving your car. You have to learn the principles before getting on the road. 

Unicorn Warrior is a complementary product that frames these biases right into the real world. Along with the best strategies that helped companies 100X their businesses within months or weeks.

Brainiac offers lifetime access to the database. 

Unicorn Warrior provides only a yearly access.

What’s the difference between this platform and many other?

I haven’t yet found a place like this one, that’s why I’ve created it. 

All the other places I’ve come across, offered only a fraction of useful details regarding viral case studies featured here. And most of them considered the success of the business or campaign to the sheer luck

As for the cognitive biases, I’m aware of only 1 company that provides something similar, yet different, and for 4X price.

Is this the final product?

Nope. I still consider this platform, the way it looks, works, provides as a very early stage startup.

Call it MVP if you want 😉

Will prices stay the same?

If you buy today yearly access, your prices will stay the same forever. 

There are still people in the community that supported my project at its beginnings. They will keep paying the initial price of $15~/year forever 

As for the normal prices, they will go up again a few times. As the platform expands, providing more and more value the prices will increase as well. They are still quite low at the moment. For the $12.5/month you can get 2 coffees at Starbucks

This platform ethos in 5 steps:

  2. We create our products providing only the smartest, science-backed, and already-proven techniques, to show you how the most creative companies in the world did it. 

  3. We provide this information in the simplest terms to let anyone use it.
