How can a new racer or startup team get sponsor attention without an established track record?

For new teams without history, start by: 1) Seeking product deals first to prove yourself rather than asking for cash. 2) Approaching sponsors with a 'let me prove to you' mindset rather than promising unrealistic results. 3) Demonstrating what you can do outside of racing to promote the brand - you don't have to be on a race track to get a racing sponsorship. 4) Showing you have the right crew, equipment, and professional presentation even if unproven. 5) Being willing to work hard for it and grow the relationship over time. Many of the biggest sponsorships started as small product deals and grew as both parties developed together.
