Product Manager, Growth
2012 - Present · over 2 years
Gustaf is a wonderful guy, a brilliant product designer and manager and understands growth exceedingly well. He is super helpful to companies he advises and invests in and doesn't hesitate to roll...more up his sleeves to dig in. We've worked and invested together.Joseph Sofaer
I know Gustaf both as a co-worker, co-founder and a friend. There are few people for who's opinions and ideas I have more respect and put more trust in than his. Anyone who gets to work or spend time with Gustaf should consider themselves lucky.
Gustaf is a quick thinker and learner. Those two attributes make him a fearsome product person. I've personally witnessed him twice make two separate projects into relatively large ones, voxer being the larger one by far.
I've learned a lot from Gustaf. He has exceptional insights into what is working and why. He is data driven and has no time for hype or popular myths. Tom Katis, Voxer.

Gustaf is great! The fact that he has helped grown 2 companies to millions of users (Heysan and Voxer) is testament to his deep understanding of consumer products and growth. Very recommended as an advisor if you're lucky to get him.

Gustaf has been a great mentor to me at Airbnb and I owe him a lot of my future success. He empowers people by believing in them. He is candid and builds trust at first sight. His team loves him. He pushes the boundaries on experimentation and I would go so far as to say that Gustaf is almost biologically wired to be a growth guy. It’s my honour to have worked with him, and I hope I will again someday.
