Babybin is a product delivery service for parents to receive the essential products they need to raise their baby from 0-24 months old. Babybin selects products based on the individual needs and preference of their members and ships bins filled with consumables, development products, baby gear, and more straight to their front door each month. Not only does Babybin provide new parents with the items every baby needs, but also anticipates the needs of new moms and dads to avoid those “uh oh moments" by shipping products at the right stage in a baby’s development (think about receiving a baby walker 1 month before your baby begins to walk or a teething toy just before that first tooth pops through!). Babybin utilizes the same successful business model as Trunk Club and Stitch Fix.

CommonEdits, Inc. is a technology company that specializes in open source music production and distribution. Through our proprietary platform artists can create and sell new music and merchandise while we take care of licensing, publishing, and digital distribution. This provides independent artists a path to financial success and allows them to focus on making music. Ever since Napster paved the way for the iPod the physical limitations for global distributions have dwindled to practically nothing. We are reaching a tipping point where independent artists no longer see signing a deal with major record as a necessity since they can reach their audience themselves. CommonEdits lowers the cost, and thus the barrier of entry, to having marketable music and merchandise.

Submitting customer service feedback is a pain, and often not worthwhile. Thanks to GripeO, users can easily submit feedback for any company in under minute, resulting in a cathartic and rewarding experience where GripeO delivers the feedback on their behalf, saving them time and frustration, which often results in a positive resolution. Depending on the seriousness of the issue, the user may leverage GripeO tools to increase the visibility of their gripe and the odds of acknowledgment, and should the business still ignore them, GripeO can match the ignored gripe to a different competitor interested in competing for their business.

Our families today can often include traveling parents, military members and distant relatives. One of the hardest things to bear when separated from your child or young relative can be the lack of engagement and connection with them. That engagement while learning can be crucial for a child's educational foundational and the connection that is fostered can have an enormous effect on a child's psychological development. Most turn to phone or webcam conversations to connect but a five year old child has the average attention span of 5 minutes which means very little substance and meaningful moments. Now using the latest face-tracking technology we seamlessly transform the normal video chat into a fun and interactive gaming environment that will keep both parties entertained for hours. Kinskii is changing the way you connect with the child in your life regardless of distance. Bring play and learning into your conversations and you can create memories like never before!

Prepify is making high-end, adaptive, online SAT prep free for students anywhere by charging universities for personal introductions to top admissions candidates on the platform. Thousands of SAT-takers each year can't afford test prep. Millions write off college altogether, unaware of the big need-based scholarships most top schools offer. And colleges still struggle to recruit more than ten percent of their classes from low-income families. It isn't news that the colleges are failing at finding socioeconomically diverse applicants. What's news is that we can change that.
