The short version

How I grew a company selling to Fortune 500s by >550% in less than two years by shutting up and listening.

  • Founder quit his job and is now full-time CEO and fully dedicated to his mission.
  • Grew the ARR by >220% within 11 months and now up >500% in two years.
  • Tripled Discovery Calls right after launching our new offer.
  • Built a community that grew the company for us instead of chasing after them.
  • Built key partnerships with key figures like the CDOs of ASML, Lufthansa, Bentley and senior executives at Microsoft, Spotify, Merck, Deutsche Bahn and others.

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 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.

The short version

How I helped a climate startup raise >3M€ by threatening their investors' lives.

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.
