Matty Driesnack is Co-Founder and COO at RATLOG (YC F26), a commercial space launch startup building reusable heavy-lift rockets powered by an engine with up to 90% fewer parts than conventional designs, selling launch capacity by the kilogram.

Matty studied Business Administration at Technische Universitat Dresden (TUD), where he first connected with his co-founders through the YETI Fellowship entrepreneurship program and developed a passion for the startup ecosystem.

As COO, Matty leads RATLOG's commercial and operational activities, spanning manufacturing partnerships, fundraising, sales, and business development, bringing sharp operational instincts honed across multiple early-stage ventures.

Prior to RATLOG, Matty served on the founding team at askLio (YC S23, a16z) as its ninth hire, co-founded Accyra, a document-matching automation platform, and served as Founders Associate at FLEXCELERATE Solutions, a TUD spin-off, and Startup Factory boOst, where he launched Dresden DeepTech Connect.

RATLOG hot-fired its first engine in just four months for under $30K and has already signed $400M in launch reservations, positioning the company as a formidable challenger in the commercial space launch market.
