How to Feel Your Emotions: the entry page, on a laptop

The short version

600,000 people watching Joe, and nothing for them to do. No lead magnet worth the name, no step between watching a video and paying for a course. I designed and built two practice products that do both jobs at once: they earn the email, and they open a new pillar where people practise instead of consume. Both are launched.

  • How to Feel Your Emotions: three guided exercises with Joe, audio and journaling.
  • The Happy Money Game: Joe's negotiation game as a printable toolkit.
  • Both gated, both feeding the paid courses, both built by me from the first wireframe to the deployed build.

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 full story

Art of Accomplishment is Joe Hudson's coaching company. He has coached teams at OpenAI and leaders at Apple, Google and SpaceX. The free side is a podcast and a YouTube channel. The paid side is courses and coaching that start in the thousands.

The hard part

A lead magnet is easy. A lead magnet that fits the business model is not. It has to stay free, it has to earn the email, it has to hand people to the paid courses, and it still has to give a real extension of value over just watching. Most companies pick two of those four. AoA's audience could tell the difference, so we needed all four.

What I built

Two products, end to end, by myself: product, copy, design, code, audio and deployment. How to Feel Your Emotions is a guided experiment. Three exercises with Joe, two on audio and one in writing, with a how-to-run page and a journal that stays on your device. The Happy Money Game takes an eighteen-minute video of Joe's and turns it into a toolkit you print and play during a real negotiation.

Exercise three, journaling with the five-minute timer running, on a laptop
Exercise one, Stop feeling, on a phone

Where it stands

Both products are launched and used every day. They sit behind an email gate that grows the list and hands people to the paid courses.

Full story, numbers and a live demo once AoA signs off. Happy to walk through it on a call.

Data Masterclass Europe: the members, hands up

The short version

ARR up 550% in two years, from no offer at all to a membership that Fortune 500 data leaders pay for. The method was shutting up and listening.

  • ARR up 220% in the first 11 months, up 550% after two years.
  • 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.
  • A community that grew the company for them, instead of them chasing after it.
  • Partnerships with the CDOs of ASML, Lufthansa and Bentley, and senior executives at Microsoft, Spotify, Merck and Deutsche Bahn.

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 Data Masterclass team and members after an event

The full story

Data Masterclass is a membership-based company offering coaching, advisory and curated events to Data & AI Leaders at Fortune 500s and tech scale-ups.

Context: It kinda sucks at the top

If you're a CDO (Chief Data and AI Officer) or CIO at a Fortune 500, you're expected to transform a 10,000 employee company with AI while employees hope to keep their jobs. Fun start.

You also report to people who have zero clue what it is you do so your budget gets questioned every quarter. The only people who understand you work at a different company in a different postal code.

The founder was in that exact position when we started working together. So he hired me.

Problem: we had… nothing

  • Data Masterclass was not profitable.
  • It did not have an offer. Zero, nada.
  • The founder wanted to enter the red ocean market of tech conferences.
  • He was a full-time employee as a corporate executive.
  • And had only run one event as a proof of concept.

Stop assuming what people want and actually talk to them

I know, crazy. I talked to CDOs, Heads of AI and other very serious people by hopping on every call with no agenda which many of them found… odd.

I didn't ask any leading questions, I didn't pitch anything: I just listened about their experience at work. Some of them even ended up telling me about their families.

After a few weeks, the results were in. These executives didn't want another tech conference. They wanted a place where they could connect with their peers. A place where they didn't feel like every second person was shoving a pitch down their throat.

In fact, most were feeling a little lonely at the top. Which led to our second biggest realization.

Stop acting like cult leaders

Every organization I've ever worked with dreams of becoming a community. But on one condition: they get to be the cult leaders. We did the opposite.

We facilitated introductions between people who'd actually benefit from knowing each other, created space for them to work on real problems together instead of sitting through panels, and made each interaction with us feel personal.

Before each event and sales touchpoint, we'd research what every attendee was working on, what they were struggling with, who else in the room they should meet. This showed the kind of preparation that people feel immediately and makes you feel important.

Governments in Germany and Switzerland
Name
Undisclosed, B2G contracts

The short version

3M€ raised after we rewrote the pitch around each investor's own portfolio. The technology had always been real. The story was asleep.

We gave each investor a personalized climate risk report for their own portfolio companies. It was a preview of what the platform could do, built specifically for them, so they could visualize what no other pitch had ever done: how much value would be lost from their portfolio if climate damage wasn't prevented.

The full story

Johnny (not his real name) built something important: a platform that uses machine learning and climate models to tell you exactly how floods, heatwaves, storms and other climate threats will hit companies and governments' critical infrastructure.

The technology was real and the science was solid (trust me, I'm a marketer).

Problem: zzzzzz

Every time Johnny pitched the idea to investors, he sounded like lots of other climate founders: earnest, technical, and sooooooooo boring (sorry, Johnny).

Threatening their lives

For government folks, we created a report about their office neighborhoods. It sounded something like this:

"Your office's neighborhood's power grid will fail in a Category 3 flood and we can tell you exactly which transformer blows first and what it'll cost you."

Suddenly it went from a boring climate SaaS demo to how their building's electricity could stop working within a couple of years.

It turns out threats are perfectly fine negotiation tactics when they are delivered in a PPTX.

This work is confidential.

The startup's name stays off the page because of its government contracts. Email me if you'd like to hear the rest.

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

The short version

A YouTube channel with 50,000 subscribers became a media brand of 600,000 with David Guetta on the cover of its magazine. I almost got punched on the way.

Within 3 years I'd:

  • 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.

In their words

"Kevin helped us go from zero to one of the most recognized brands in the industry."
Yotam Dov · CEO, We Rave You

The full story

We Rave You is a media publication and B2B platform featuring the latest in electronic music culture and partnering with multiple Billboard Top 100 artists.

Context: everyone wants to help the young guy

I was 18 and still in high school when I cold-emailed the founder (a guy running a YouTube channel who posted on his Facebook page that he wanted to create a blog).

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

Problem: uuh who are you exactly?

We Rave You was a YouTube channel with like 50k subscribers with ambitions to grow into a blog. That's about it.

Run after the artist like a maniac

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 Martin's advice helped me getting over 10 interviews in two days with the biggest DJs on the planet. Our following jumped 200% after publishing our first batch of interviews. This directed our strategy to land partnerships with the biggest clubs.

Role

Type
Governor race · Mexico
Result
Under-30 favorability up double digits in the final six weeks

The short version

The youth campaign of a governor's race in Mexico, rebuilt around the violence young voters were actually afraid of while the party wanted to talk about potholes. Still my biggest disappointment.

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 full story

Everyone under 30 had left the building.

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.

Meanwhile there was an entire generation screaming about not feeling safe in their own state and no politician willing to address it.

Reading the f*cking room?

There was a massive, organic movement of young people talking about safety and violence in Morelos but the party's strategists had decided it 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.

Results

Under-30 favorability upticked during the final stretch of the race but it was too late. Who could've guessed?

I was grossed out of politics and promised to never touch it again.

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

The short version

Affiliate tracking software is the most boring category on earth, and every vendor in it hides its prices behind a demo button. Six months of customer interviews became a new position, a new pricing strategy and a segment the company had never sold to. Trackdesk has grown 6x in the two years since.

  • Customer interviews first. The position came from what buyers said, not from a workshop.
  • Repositioned as the transparent, slightly edgy option in a category that hides everything.
  • A new pricing strategy that opened a segment the company had not been selling to.
  • Social engagement up 700%. Word of mouth became the main channel.

In their words

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

The full story

Trackdesk sells affiliate tracking software. Possibly the most boring sentence in the English language.

Problem: a category that hides

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.

Ask the customers, then say the opposite

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.

Pricing as positioning

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. Growth started coming from word of mouth.

Results

Social engagement up 700% during the engagement. Trackdesk has grown 6x in the two years since, with the positioning carried forward by Michal, their former CMO.

Old but gold

Who I am

Kevin Barrera-Joubert

Raised in Mexico and France, educated in the Netherlands, nomadic since. Eight countries lived in, five languages spoken.

Turn the globe: the lit countries are where I have lived, and the hatched ones are where I can speak the language.

What I do

I'm interested in making sense of the world: seeing how it all connects, simplifying it, and turning that into products and experiences people can actually use. Whatever the title says, that is the job. I work on experiences.

Right now that means guided products for Art of Accomplishment, a quiet anthology of poems, small experiments that ask you to do something instead of scroll, and looking for the next mission: a small, early team where content, product and partnerships are one job.
