What we do and believe


Ollie is a platform that empowers people to manage and offset their personal footprint.

We help individuals take sustainable decisions on a daily basis, so everyone can contribute in the combat against climate change. Energy is a broad term, it doesn’t only cover household energy (electricity and gas), it includes your mobility footprint, your meat consumption or the waste you produce. We want to help people manage their footprint holistically through data and technology. 

Our belief is that the personal footprint will gain in importance. Companies can offset their employees’ footprint (> with Ollie Energy), or banks can tie their loan conditions to your footprint score (> with Ollie Energy). 


We just closed a seven-digit seed round, our headquarters are in Vienna. We are looking for fun, talented and experienced people who want to join us. We will use technology to combat environmental challenges. 


The company is founded by successful serial-entrepreneurs and renowned investors. We are backed by angels, who founded unicorn companies and are in it for the long run.




We are looking for a lead UX/UI designer who is creative, hands-on and user focused. We will be iterating fast and approach things very pragmatically. You like to do customer research, work data based, explore user feedback and optimize in small steps. You think out of the box, try crazy things, push it if it works or kill it if it doesn’t. You can design beautifully and people look at what you do and love it.

You have designed, launched and optimized mobile products before.
