Usually, ghosts stay hidden.

But today, two of them are stepping into the light: not as co-founders this time, but as believers who decided to back Haamu from the very beginning. 👻💜

Meet Mikko Seppä and Paavo Laaksonen: serial entrepreneurs and seasoned co-founders, professional influencers (the real kind), and now, our first investors through their investment company Xcalibur.

Why are Mikko and Paavo a perfect fit for us?

Because we know that they know how real growth doesn’t come from shouting louder: it comes from showing up smarter. ✊

Both of them have seen how influence shapes markets: from co-founding companies like HeadQ, Advance B2B, and Matter Agency to leading different teams, writing books (Mikko), and, occasionally, posting increasingly ridiculous LinkedIn photos (Paavo).

When we first talked about Haamu, Mikko put it simply: “Influence isn’t new. But the way you earn it is.”

With Haamu, they saw an opportunity to make strategic visibility scalable, combining AI with a human touch to help real people cut through the noise.

Hear it from themselves 👇

When we asked Mikko, the answer came down to three things:

“At Xcalibur, we believe everything in business comes down to influence. Whether you're selling a product, a mission, or a vision, it's about getting people on your side. And today, influence lives in social media. Leaders and executives have a huge opportunity to build real connections (and real impact) when they show up as people, not as faceless companies. People follow people, not brands.

That’s where Haamu steps in. They help decision-makers and domain experts stay visible, credible, and relevant in the feeds that matter. With a smart combination of AI and service, Haamu makes it easier to build personal brands that cut through the noise. We’ve seen the rise of AI tools firsthand through our work in marketing, and we believe there’s a better way to deliver these services: more data-driven, more consistent, and more human.

So why are we investing? Besides seeing a clear market need and a sharp execution, we invest in teams. Teams that’ve experienced the problem themselves and have the expertise to solve it the right way. And yeah: knowing the founding team from past projects didn’t hurt either.”

In short:

👻 Founders who have lived the problem.
👻 A massive and growing market.
👻 Perfect timing.

Or, as Mikko summed it up:

"It’s the combination of a great team, a big market, and hitting the sweet spot at the right time."

We’re also thrilled to share that Mikko has been appointed as the Chair of the Board at Haamu, helping us steer the ship as we turn our vision into reality.

We couldn’t be more excited (and a little honored) to have Mikko and Paavo on board — not just as investors, but as true believers in Haamu's mission. 👻
