San Francisco CalHeat is the leading team handball club in the United States. CalHeat's men's first team, women's team, and youth team are all reigning USA Team Handball National Champions, and the men's first team recently won the North American & Caribbean Continental Championship. We are looking for sponsors as our men's first team embarks on a journey to play in the IHF SuperGlobe – essentially the club World Cup – this November in Saudi Arabia against the best professional teams in the world, including powerhouse FC Barcelona, SC Magdeburg, and reigning European champions Barlinek Industria Kielce. CalHeat is leading the development of handball in the US through a robust youth program that supports both boys and girls ages 8 to 18 through practices, games, tournaments, and clinics. We are eager to grow this incredible sport in our home country and look forward to engaging with potential brand partners who can support us on this journey.

After more than ten years and thousands of brand deals with athletes and creators at OpenSponsorship, here is how we think about it, and the framework we use with our clients.
