We will provide migraine sufferers with accurate diagnosis, personalized treatment options, and accessible care, all while raising awareness about the true impact of this condition.

Embla is a turnkey, digital weight care solution built for cost-conscious U.S. employers. We combine GLP-1 microdosing with expert psychology-based coaching to deliver 16.7% average weight loss in 12 months — using 55% less medication.

No health plan integration. Fully live in 7 days with simple, pay-per-active-member pricing. Founded in Denmark — the home of GLP-1 — Embla is trusted by U.S. health systems and self-funded employers. Our approach is validated by one of the largest real-world GLP-1 studies and supported by partnerships with the University of Copenhagen and biotech giant Novonesis.

Danish Tech Startups (DTS) is an independent industry association founded by entrepreneurs – for entrepreneurs. We work to make Denmark the best place to start and scale a tech company, because strong startups are essential to future growth, welfare, and democracy. Our members are behind some of Denmark’s most successful tech companies, and we fight for better conditions through employee stock options, R&D tax credits, and access to talent. At the same time, we provide practical tools and strong communities: exclusive events such as Townhall, Unicorn, Exit and M&A Academy, as well as mentoring programs and networks that make a real difference. For us, it’s about more than startups alone. It’s about safeguarding Denmark’s digital sovereignty, creating the jobs of tomorrow, and securing a free and resilient democracy.
