Code Four

Modernizing the police workflow.

Code Four slashes the administrative burden on law enforcement through AI-driven automation. Officers spend up to a third of their shifts manually transcribing body camera footage, creating inaccuracies, reducing transparency, and cutting into frontline duties. We're here to eliminate these inefficiencies by integrating with body cameras, record management systems, and digital evidence management systems—acting as a software layer for data processing. We free the most overworked and underappreciated people in the world: police officers.

CodeCombat

Game that teaches computer science to middle and high school kids.

CodeCombat is a multiplayer programming game for learning how to code. With thousands of schools and millions of students, we are bringing K12 computer science education to everyone, regardless of gender, race, or background. Everyone should have the opportunity to learn. The ultimate goal of CodeCombat is to bring more users into the field of computer programming by making the logic and syntax more accessible and enjoyable to learn. The end game is to educate a whole new generation of computer programmers that started their journey by slaying ogres and defending their castles from oncoming enemy hordes. We teach Python, JavaScript, and other languages directly in the browser. Teachers with no computer science background can get started in five minutes. In a world where all programmers have had to be second-language learners, do you want your students to become native speakers of code? Let's chat about bringing CodeCombat to your school!

Coderhouse logo

Coderhouse

Effective and accessible online live education.

A web app that offers live online courses in programming, design, data, online marketing and more. Our courses are nearly as affordable as online Moocs (~$40 a month) and as effective as Bootcamps. We achieve this by running 100 person live classes with one expert professor and one mentor per 15 students. Every class, students need to turn in assignments that are corrected by their mentors and at the end of the course they need to turn in and approve a final project. We also help our selected students with careers services such as mockup interviews, Linkedin enhancement, and more. All of this creates a level of accountability that allows us to achieve really low churn levels (<9%). Our career tracks last between 9-11 months and we give our selected students their money back in case they don't get a job 6 months after they are done with the course.

Codyco

AI Receptionist for Hotel Groups

€5,000 in additional bookings. In 4 weeks. For a 53-room hotel. We help hotel groups turn missed calls into bookings. This it how it works: - They send their missed calls to us. - Our AI answers and takes the booking. - The booking goes right into their PMS. Even with call centers and central reservation departments they are still losing 5% of calls. That is a seven figure revenue leak. We already work with 7 hotel groups that run 350 hotels recover that potential. Why us? We used to build software that can’t fail for massive companies. We started Codyco after a friend told us how much money he was losing from missed calls. We built the first version just for him. Now we give hotel groups the reliable AI they need, so they never lose a booking on the phone again.

Cofactor Genomics logo

Cofactor Genomics

Cofactor closes the precision medicine gap with predictive diagnostics

Cofactor uses RNA and Predictive Immune Modeling to build better biomarkers and improve patient outcomes. Led by Jarret Glasscock and a group of expert human genome scientists,Cofactor has built a new category of diagnostic technology powered by unique and powerful RNA data models built on terabytes of data. The team recently had their technology validation peer-reviewed by the organizations that set standards for diagnostic technology (CAP, AMP) and is publishing in the Journal of Molecular Diagnostics. In addition, the team made news when Cancer Physicians who sit on the committee for patient treatment guidelines (NCCN) presented a clinical study using Cofactor’s technology showing superiority in predicting the patients who will respond to immunotherapy. This initial application is an acute problem recognized widely in the rapidly developing immunotherapy industry and represents north of a billion dollar TAM. After a number of recent key milestones, the team is taking the technology more broadly to 50% of cancers diagnosed in the US. Current investors include Menlo Ventures, DCVC, and Ascension Ventures (this last investor representing the funding arm for 13 National U.S. Healthcare Systems).
