Bounce operates a platform that enables luggage storage and package pickup worldwide. We are building the future Operating System for brick-and-mortar businesses, helping them earn more money with their space while simultaneously building consumer products that users love. Over 1,000,000 people have used Bounce to store their luggage while traveling. We launched on Product Hunt in 2019 as the #1 product of the day and have grown to more than 2000 cities worldwide since. We're backed by top-tier investors in Silicon Valley and pride ourselves on being a scrappy team that moves really fast. *Inspiration* The founder, Cody, has lived in 15 cities and traveled to 60+ countries. We know how annoying it is when your things drag you down. *Lightbulb Moment* A few years ago, I was getting drinks with co-workers after work on a Friday. A friend said he’d join but had to go all the way out of the way to drop his work bag at home. I thought―"what a waste of time; there's got to be a better way.” *Problem* People spend so much time planning their days (and their lives) around the things that they own. The status quo when you land in a new city is to go straight to the airport just to drop your stuff off, even if it doesn’t make sense otherwise. *Solution* Tapping into local hotels and shops, we can open up storage space nearly everywhere in a city. Open the Bounce app and find a safe and secure place to leave your things (delivery back to where you’ll be later coming soon!). *Key Features*: 24/7 storage locations Secured and insured Easy pricing: $6 / day 24/7 customer support Get to know your local shops!

With Fella Health, patients meet a board-certified obesity doctor to prescribe FDA-approved medications, while they undertake personalized health coaching through our app. Obesity is the largest chronic disease in the US (>$100bn spent each year) and the traditional solution ("move more, eat less") only works long-term for ~10% of people. But obesity treatment is radically changing due to a new wave of medication options which are 2-3x more effective than previous options. In addition, only 10% of those using weight management services are men: all programs market to women, not tackling the stigma men feel around this. Fella's founders are Luke (linkedin.com/in/luke-harries) & Richie (linkedin.com/in/richard-cartwright). We studied together at Cambridge University. Luke studied medicine and developed a patented AI approach to detecting cancer at a YC bio company, before moving to Microsoft Research. He did a masters in Computer Science after Cambridge. Richie personally struggled with stress eating for 6 years. After Cambridge, he built and sold an AI company working with the UK government. He built a 10k-follower community around men's stress eating.
