Our members' background


Katharina S.

GreenTech founder, sharing her experience since 2020

Always have the right person to talk to

"The insights I get out of a personal conversation are more valuable to me than 10 hours of google research.

Besides, I prefer advice from other founders over booking professionals" 

Why sphere?

Your network

Hard to find the right person.

Favours owed to different people accumulate.

Excessive networking needed to cover a broad spectrum of topics.

On demand.

Real-world experience.

No matter on what topic.

Professional advisors

Have never been in your shoes.


Too costly.


Missing the practitioners' approach.


"I love to support others. sphere allows me to make an impact with my experience without any long-term commitments. 


I only spend 2 hours per month on it, but I can still create significant value for other founders on topics that matter."
