Why I Left Europe's Top Rocket Lab to Start My Own Startup

Lukas Werling is the CEO and co-founder of ISPTech, a German space startup developing green propellants that eliminate the need for hazmat suits and could slash space propulsion costs by 75%. The company has in a short time secured €2 million in funding with three orbital missions lined up for flight later this year.In this episode of Rockets and Radars, Lukas shares his journey from a mechanical engineering student rejected from aerospace programs to spending 14 years at DLR (Europe's premier rocket testing facility) before selling his motorbike to raise startup capital. From supervising thousands of rocket engine hot firings to managing Europe's most unique test facility, from watching technicians in hazmat suits handle toxic propellants to developing fuel safe enough to handle with bare hands, Lukas explains how patient research and perfect timing created a company that had paying customers before it even officially launched.Want to get hired in ISPTech? https://tally.so/r/mOq9b7Want to invest in ISPTech? https://tally.so/r/nGE4qp-----------------------------------------------Chapters:(00:00) Introduction(03:09) Getting Rejected(08:00) Breaking into DLR(14:34) Finding the Perfect Co-founder(21:01) The Spin-Out Decision(30:32) Incorporating with €25K: Selling the Motorbike(35:56) Getting First Customers Before Incorporation(44:36) Funding Journey: €2M Pre-Seed(51:17) Future Vision: Space Infrastructure & Mobility(54:34) Quick Fire Round: Biggest Mistakes & Key Decisions(58:52) Advice for Researchers-----------------------------------------------Takeaways: 1) Persistence beats rejection - keep asking until someone says yes. "I talked to my professor during his lectures. I went to his office several times... he was always saying, yeah, I will reach out." Lukas got into DLR by repeatedly asking his professor for an introduction until he finally made the call.2) Technology maturity trumps perfect business plans for deep tech - "We had like years and years of testing at the test bench... many companies didn't have those possibilities." Having proven technology from 14 years of research gave them customer confidence that business plans alone couldn't provide.3) Know your customers' pain points before you spin out - "We knew some spacecraft manufacturers, some people... what their issues are, what their pain points are." Don't guess at market needs - work directly with your future customers to understand their problems first.4) Hire people you've worked with for years, not strangers - "The first people we hired were from this... student team... We know them for years." Your early team should be people whose work quality and character you've personally witnessed over time.5) Speed beats bureaucracy when markets are moving fast - "We can decide, we can make progress as a company much, much faster... people from DLR approaching us, ah guys, can you do it so fast?" Startup agility is your biggest advantage over large institutions.6) Never start work without a written contract, no matter who asks - "The biggest mistake I made is to start some work... without a written contract... it never materialized." Even trusted contacts can disappear - always get agreements in writing before starting any work.7) Build your network before you need it - "We had our network. Of course, we knew some spacecraft manufacturers... this was an advantage." Relationships built over years become customers and partners when you're ready to commercialize.8) Focus on customer contracts, not just grant funding - "We need, just frame contracts... As a company you want customers and not additional grant funding." Paying customers validate your business better than government grants ever will.9) Plan backwards from your vision to find the first step - "You want to build this huge power plant... plan backwards... solve one issue after the other." Break dreams into manageable technical problems you can solve sequentially.
