Sting Core
We've unified our incubator and accelerator into a single, high-impact experience, giving you exactly what you need, when you need it, to build a lasting company. We're now accepting applications for October 2025 start.




















Sting Core - Accelerate What Matters.
One journey. Real results. Lifelong impact. Sting Core is our flagship six-month program for ambitious tech founders ready to fast-track their startups' growth with purpose and precision. Whether you're building in climate, health, AI, or DeepTech, this is where standout ideas become investable companies.
What You Get:
Hands-On Coaching from Battle-Tested Founders
Our coaches have built, scaled, and exited startups, and they bring insight you won't find in textbooks or theory. You get honest, experienced guidance from people who've done it before.
Investor Access Like Nowhere Else
Through Propel Capital investment and Sweden's strongest early-stage investor network, we offer personal intros to angels, family offices and VCs that others simply can't. You'll connect with the people who fund and fuel Nordic innovation.
Go-to-Market Clarity, Strategy, and Speed
We help you define your customer, nail your positioning, and craft a sales and funding strategy that turns potential into momentum.
Plug Into Sweden's Beating Startup Heart
Sting is at the centre of the Nordic startup scene. We put you in rooms you didn't know you could get into- with founders, operators, corporates and policymakers shaping Europe's tech future.
Sting Demo Day
Cap off Sting Core by pitching live at Sting Demo Day, an invite-only event where 200+ investors are handpicked to match your company's stage and domain. You'll share your vision, your traction, and your product in front of the people who can help make it real.
A Focus on Real-World Impact
We back the builders solving climate change, revolutionising health, advancing deeptech, and pushing AI toward real-world applications. Your mission matters-and we'll help you push boundaries to make true impact at scale.
