How to Feel Your Emotions: the course menu with its three exercises, on a laptop

The mission

Designing and building the new experiential layer of Art of Accomplishment.

Art of Accomplishment is the company founded by Joe Hudson, coach to executives at OpenAI, SpaceX, Apple and many more of Silicon Valley's biggest names.

Working closely with Nibras Ibnomer, AoA's Head of YouTube, I crafted interactive prototypes for two products and one experiential content library.

The work culminated in two full experiments, the Experiments library that holds them, and a presentation to Joe, receiving approval for launch in September 2026.

On Joe

"One of his superpowers is that he deeply understands emotional clarity and how to get there; this will be one of the most critical skills in a post-AGI world."
Sam Altman · CEO, OpenAI

The Data Masterclass team and members after an event

The mission

Turning an idea with no business model into a membership that Fortune 500 data & AI leaders pay for.

The result

ARR up 550% in two years.

  • ARR up 220% in the first 11 months.
  • Discovery calls tripled in the three months after the new offer launched, against the three months before.
  • The founder left his corporate role and is now full-time CEO.
  • Partnerships with the CDOs of ASML, Lufthansa and Bentley, and senior executives at Microsoft, Spotify, Merck and Deutsche Bahn.

The process

Data Masterclass is the company founded by Dr. Alexander Borek to coach, advise and connect Chief Data & AI Officers at Fortune 500s and tech scale-ups. When I joined as Head of Growth in February 2024, it had run one event, had no offer, was not profitable, and its founder still worked a full-time corporate job.

Working closely with Alexander, I spent weeks on calls with CDOs and Heads of AI, pitching nothing and only listening. Needless to say, they did not want another tech conference. They wanted a room of peers who understood their job, so I reimagined the entire business model along with Alexander and repositioned the company to become the most hospitable space for these executives. We facilitated introductions between people who should know each other, connected them to real problems they could work on together, and made sure we understood their every need to have the most high-touch service in the industry.

A note on the visuals: the brand identity was created by others. My part was the business behind it.

In their words

"Kevin helped me rethink my entire go-to-market strategy. He is smart, fast, focused and effective. I highly recommend working with him."

The founder, name confidential

The mission

Rewriting a climate startup's pitch so every investor could see the risk in their own portfolio.

The result

Over 3M€ raised.

The pitch stopped being a climate SaaS demo and became a question about each investor's own money.

This work is confidential.

The startup's name stays off the page because of its government contracts.

The process

The startup uses machine learning and climate models to predict how floods, heatwaves and storms will hit critical infrastructure, and sells to governments in Germany and Switzerland. The science was solid. The pitch sounded like every other climate founder's: earnest, technical and easy to forget.

Working closely with the founder, I built the funding narrative and the investor targeting. Instead of a generic demo, each investor received a climate risk report on their own portfolio companies: a preview of the platform, built for them, showing how much value they stood to lose if the damage was not prevented.

Government buyers got the same treatment for their own offices, down to which transformer in their neighborhood's grid fails first in a Category 3 flood.

We Rave You, July 2020: David Guetta and MORTEN on the cover

The mission

Turning a YouTube channel with 50,000 subscribers into a media brand the biggest DJs on the planet wanted to talk to.

The result

A media brand of 600,000 with David Guetta on the cover of its magazine.

  • Our following jumped 200% after publishing the first batch of interviews, which pointed our strategy at partnerships with the biggest clubs.
  • Helped grow our following to 600,000 people back when being viral was super rare.
  • Built the first connections to have David Guetta's face on the cover of our magazine.
  • Built partnerships with labels like Sony Music, Spinnin' Records and artists like Swedish House Mafia, Oliver Heldens, Above & Beyond.

The process

We Rave You was a YouTube channel with like 50k subscribers with ambitions to grow into a blog. That's about it. I was 18 and still in high school when I cold-emailed the founder, after he posted on his Facebook page that he wanted to create one.

I was hired as an Editorial Writer and quickly grew my role into an undefined mix of partnerships, editorial lead and business development.

I almost got punched by Martin Garrix's manager. I did indeed literally run after him in the backstage of EDC Mexico. Once his manager had calmed down, I explained under my blushed 18-year-old cheeks I was here on business.

His manager wasn't having it but Martin did offer me to have a drink. He gave me some advice: talk to artists like regular people and to the managers like they're superstars. Solid guy. Turns out it helped me get over 10 interviews in two days with the biggest DJs on the planet.

In their words

"Kevin helped us go from zero to one of the most recognized brands in the industry."

Youth campaign
With
A team of students

The mission

Rebuilding the youth campaign of a governor's race in Mexico around the violence young voters were actually afraid of, while the party wanted to talk about potholes.

The result

Under-30 favorability up double digits in the final six weeks.

It was too late. Who could've guessed? Still my biggest disappointment: I was grossed out of politics and promised to never touch it again.

The process

The state of Morelos had a serious violence problem. Teenagers were getting disappeared. Young people had organized a real social media movement around safety: it was impossible to miss. The party's campaign slogan was about fixing potholes.

The party had completely written off young voters and young voters had returned the favor. Turnout projections for under-30s were terrible because the campaign was obviously designed by people who hadn't ever opened Twitter/Instagram. The party's strategists had decided safety was too risky to touch.

We (me and other students hired to help) scrapped the pothole messaging for the youth campaign and rebuilt it around what young people were actually terrified about: their safety. The shift wasn't exactly creative genius but in his defense, the candidate went to local schools to discuss with the youth for 40-odd days.

Trackdesk's pricing page: every plan and price in the open

The mission

Repositioning affiliate tracking software, the most boring category on earth, around what its buyers actually wanted to see.

The result

Trackdesk has grown 6x in the two years since.

  • Social engagement up 700% during the engagement.
  • A new segment the company had never sold to.
  • Word of mouth became the main channel.
  • The positioning carried forward by Michal, their former CMO.

The process

Trackdesk sells affiliate tracking software. Possibly the most boring sentence in the English language. Every competitor showed the same website: the same features, the same promises, and a "book a demo" button where the price should be. When everyone hides, nobody stands out, and the buyer picks whoever answered the email first.

I spent the first weeks on calls with customers and prospects, listening to how they chose and what annoyed them about the category. The answer was consistent enough to build on: they wanted to see the price, they wanted plain language, and they were tired of being sold to. So Trackdesk became the vendor that shows everything: transparent, a little edgy, and actually fun to read.

The pricing strategy did the rest. Putting the plans in the open and reshaping them around how people actually bought opened a segment the company had never sold to, and gave customers a reason to tell each other about it.

In their words

"Kevin is making the impossible possible. A brilliant example of knowing your customer, understanding the competition, and building distinctive communication."

A little about

Kevin Barrera-Joubert

My background

When you grow up between two cultures, you learn early that "normal" is just whatever your family happens to do. In Mexico, I learned to greet people with one kiss on the cheek. In France, it was two. In some regions, three. In some, four, and nobody warns you which region you're in. So I spent my childhood in constant danger, leaning in for a kiss that wasn't coming or pulling away from one that was.

It's simple geometry: if one of you is switching cheeks and the other isn't, you meet in the middle. And the middle is the mouth. That's how I got my first kiss. Sorry, madame.

A few years later, I realized most disagreements work exactly the same way. Each person assumes their normal is the normal, and they hold on to it even when you show them, in black and white, that they're kissing people on the mouth.

So after graduating, I started living as a nomad, looking for more places to be wrong. Languages turned out to be the quickest way: you can't learn one without sounding like a toddler for a year, and people love you for trying.

Everywhere I've been willing to play the fool, I've learned faster and connected deeper with people. There's probably a lesson in there.
