Mercura is building AI software for the backbone of our economy.

We are one of the fastest growing companies from YC’s W25 batch and raised a heavily oversubscribed round at one of the highest valuations in our cohort. After surpassing $1M in ARR in under a year, we are looking for team members ready to go all-in to help us reach our next milestone: $10M ARR by the end of 2026.

One of our co-founders, Lukas, grew up in a trades family that has been active in the construction industry for over 115 years. Having worked on the construction site himself, he learned first-hand how slow and manual quoting still is in the industry.

In an era where AI becomes ubiquitous, we set out on a deeply personal mission: bring AI to the backbone of our economy - to the companies that keep our world running.

ABOUT THE FOUNDERS

We are Lukas, Stefan & Sean, the co-founders of Mercura. We share a deep commitment to excellence and the discipline to pursue what others might consider impossible. Two of us come from non-academic families, and we all know what it means to create our own paths and overcome barriers. This experience shapes our belief in equal opportunity and fuels our dedication to social mobility.

At Mercura, we believe that the best ideas emerge when people from different backgrounds collaborate together. We hire based on ability, mindset, and values, and we live by one simple rule: the best idea wins.

We actively support initiatives that promote diversity and gender equity. Each year, we also commit a portion of our personal income to organizations working to expand opportunity for others.

We’re a small, fully in-person team based in Munich that feels like family. We bring extraordinary people together and deeply invest in each other’s growth as mentors, teammates and friends.

We care, trust, and support one another, and we make sure that joy and collaboration is at the heart of everything we do.
