My name is Petra, and I am from Hungary. I am a 2X NCAA All- American, school and conference record holder in 100 and 200 breastroke. I finished 11th at NCAA on 200 breastroke in 2020, and 10th in 2021. I am also the Hungarian national champion on 100 and 200 breastroke. Finished 12th at European championship and I represented my country at the OLYMPIC GAMES in Tokyo and finished 15th. I graduated with a degree in psychology in 2021 and I recently started my master’s program in Educational Leadership. I believe you should sponsor me because this Olympic Games was just the beginning in my swim career. I would like to be able to continue my career as a professional athlete and keep working with my coach, Dave Rollins in the future. Please help me to make my dream true.

How do you measure influencer marketing ROI when half the numbers social media gives you are vanity metrics? It is the question brands ask us most, and it came up again when I joined Massimo Marinelli on the Berkida Ventures Podcast.
