The Chief of Staff network has been incredibly helpful for me, and I honestly started seeing immediate value on Day 1 of joining.

The network offers numerous opportunities to further growth, development, and camaraderie - I think it'd be challenging to navigate the CoS role alone without this group of people.

This group is invaluable for anyone that wants to succeed at a scaling start-up in a Chief of Staff role. No matter what challenge is thrown at you in the role (and you will see it all), someone in the group has been through it and can provide great insight into how they tackled the issue.

I recently joined the Chief of Staff Network and have already made some amazing connections. When you're a chief of staff, you're often the only person in the company with that job title -- the COS Network has people in your shoes, and it's a great place for advice, brainstorming, and community. Highly recommend!

The Chief of Staff Network has been a blessing as I ventured into a unique position that was new - not only for myself but also for SumUp. Having access to this community makes my life easier as we’re all facing similar challenges and can freely exchange on ideas and solutions.

Chief of Staff at SumUp

I came across Chief of Staff Network when considering the CoS role for the first time and found the content about the role was so helpful, I immediately became a member when I officially started the position. The content and connections continued to be invaluable throughout my entire CoS journey, so much so that I was able to work myself out of the job and into a founder role faster than I anticipated. Highly recommend!
