About
The longer version.
Who
I’m Jakob. I build things I like in Barcelona: a cargo-drone company called Grasshopper Air Mobility, AI products on the side, and whatever experiment currently has me hooked.
The pattern underneath is physical systems. Before founding, I spent four years putting software into automated warehouses across Europe. The drones came from a question I couldn’t put down (why don’t flying cars exist yet?), and in 2023 the question turned into a company.
Along the way, AI became my second team. I ship my own tools with Claude Code and Codex: research, financial models, entire products. Right now I’m curious about the capital side of deep tech, where helping builders scales past one company at a time.
Off the laptop: I’ve lived, studied or worked in seven countries, starting with an exchange year in Texas at sixteen. I speak German, English and Spanish, plus enough Catalan to order well. Chess, football, calisthenics.
If any of this overlaps with what you’re building: say hi. The coffee offer is real.
The now archive
Every now so far.
- November 2026 current Submitting client proposals, which is very interesting work. The second webinar with Corrientes took place on 4 November. Closing existing opportunities, opening new ones and setting up the right start for 2027, so the year ends on a big note, and I feel very motivated.
- October 2026 Back in Barcelona, I gave the first of two webinars on drone technology with the Office of the Vice-Governor of Corrientes and companies from the province. I spoke at the CEL logistics congress in Madrid on 22 October. I enjoyed the last rays of October sun in Barcelona and walked in Roman footsteps, discovering ruins in Premià de Mar.
- September 2026 An awesome trip to Latin America: Rio, the waterfalls of Foz do Iguaçu, the province of Corrientes and Buenos Aires. In Corrientes, Grasshopper signed a framework agreement for cooperation and exchange with the Office of the Vice-Governor. It left deep impressions on me, and I made many friends there, professionally and privately.
- August 2026 Building a SaaS for cultural companies. Preparing a trip to South America in September, and more public and private funding calls for Grasshopper. Still hot on joining the VC side.
- July 2026 Exploring the investment side of deep tech. Building Hairdresser AI. Fresh from Draper University in Silicon Valley, five days of survival training included.
