How much ownership does Propel Capital take?
Propel Capital invests via a convertible note that converts to ownership only when the company has raised at least SEK 1 million or more from external investors. This way, we avoid setting a valuation of the company too early.
Are there other benefits to having Propel Capital as a financier, in addition to the investment itself?
The purpose of Propel Capital is to connect Sweden’s best angel investors with our startups. Via the investment, we activate our angel investors to make direct investments into the company – adding both capital and experience.
Do I pay for Sting’s services?
Sting doesn’t charge upfront fees. Instead, we use a success-fee model in the form of stock warrants. If your company succeeds, Sting may convert those warrants into a small shareholding — helping us reinvest in the next generation of startups.
We’ve already participated in other programs – why should we join yours?
Sting delivers unmatched hands-on support tailored to your startup’s unique needs, combined with direct access to one of Europe’s largest and most active networks of founders, investors, and experts. Over 90% of our startups recommend Sting to their peers — and many return for follow-on programs.
We have already raised a substantial amount of funding, can we still join?
Absolutely! Having secured funding before joining Sting is common and doesn’t prevent you from participating in our program. Many startups enter with angel investors already on board, and we’re here to help you build on that momentum with tailored support, strategic guidance, and access to our extensive network.
How do you handle startups with similar or competing business ideas?
To maintain trust and a healthy community, we do not accept startups that directly compete with each other at the same time in our program. However, once a startup has graduated and been an alumni for at least six months, we may consider working with another company with a similar business idea.
