Mercura ( YC W25 ) helps the companies that build the real world move at software speed, automating the back-office work that runs the $12 trillion industry behind every hospital, school, and power plant. We started with one of their biggest bottlenecks - turning messy technical requests into accurate quotes - and grew to $2M ARR in our first year. With a team of 16, we're now targeting $10M by the end of 2026 as well as our expansion into the US.
Why join Mercura
- A foundational role. As our first Solution Engineer, you build the demo environment, the proof-of-concept approach, and the technical-sales motion, rather than inheriting them.
- Direct influence on the product. You sit one step from product and engineering, and what you learn in deals shapes what we build next.
- A large, underserved market. We automate the manual ERP work in a $12T+ industry that still runs on emails, PDFs, phone calls, and manual processes. The need is real, and the market is largely untouched by modern software.
- Real ownership and upside. You receive real shares in the company with voting rights, not just VSOP/ESOP.
- A strong team. Operators, ex-founders, and experienced engineers who set a high bar and support each other.
- A high-growth, high-commitment environment : We’re growing extremely fast because we always put our work and our customers first. If you excel in fast-paced settings and want to grow as part of something big from day one, Mercura is for you.
- Build something with real-world impact : We ship code that directly helps a massive, yet overlooked manual industry run more efficiently and sustainably.
- Build a category-defining company : Mercura has the potential to reach significance. As an early team member, you will have a direct, lasting impact on our culture, processes, technology, and product.
