The software used to manage networks hasn’t kept up with the dramatic expansion of networks themselves. The Forward Networks solution is designed to help network teams eliminate network outages and reduce time to remediate errors. Its platform enables engineers and operators to visualize and search complex networks, debug configuration problems, verify network-wide policy implementations, and predict network behavior prior to deploying changes. Forward Networks builds a software replica of an entire network to analyze its behavior. Using the network copy, the software traces, indexes, and stores the collected data, monitoring things like end-to-end behavior, verification of the network’s forwarding behavior and security posture, and close monitoring of configuration changes.

THE PROMISE With ultrasound a doctor can see into the heart of someone in cardiac arrest or into the abdomen of a woman with an ectopic pregnancy, and save their lives. 75 years after its invention, ultrasound remains an indispensable tool for diagnosis and monitoring. THE PROBLEM 60% of the world lacks access to medical imaging because current technologies are unwieldy, expensive, and require extensive training. While doctors carry supercomputers in their pockets, they still rely on the 200-year old stethoscope​ as their primary diagnostic tool. THE SOLUTION Our mission is to democratize healthcare by making medical imaging accessible to everyone around the world. Butterfly Network has raised >$350M to develop and commercialize a handheld, smartphone-connected ultrasound probe powered by AI. We operate at the intersection of medicine, engineering, and machine learning to create breakthrough technology that becomes smarter with each new patient.

We believe learning differences are parallel ways of thinking that should be celebrated. Our mission is to provide students with the resources and encouragement to succeed in the classroom and beyond. To us, this means helping them build confidence in their unique strengths and create strategies to work around their weaknesses.
