Razu is a networking and collaboration service for music creators in the music industry. Many artists are choosing the independent route instead of getting signed to a major record label. Without a label, an artist must have key players in order to make a successful project: an engineer, a producer, complimentary artists, songwriters, and the list goes on. Many artists don't have access to these key players. Razu provides the networking tools in order for you to find the next playmaker for your project. Razu also provides the collaborative tools in order for you to make music virtually without having to be in the same music studio.

AlphaLab Capital Group is a technology-driven trading group that transacts over $2B daily in cryptoassets on 40+ exchanges, both centralized and decentralized. Since 2017, we have consistently generated exceptional returns (aka alpha). We were one of the first movers in quantitative trading on the blockchain, and today we operate thousands of algorithms 24/7 on a globally distributed network of trading servers. We see blockchain as the foundational technology of our generation. Just as ship-building innovations in the 1450s launched the Age of Exploration or TCP/IP in the 1970s launched the internet as we know it, blockchain now opens up new worlds of possibility. Much of the infrastructure, applications, and software that we will all take for granted in a few decades are only glimmers in someone’s imagination today. We founded AlphaLab because there is huge potential in building that future. It’s also going to be a lot of fun.

Scientific progress in medicine is accelerating, but getting breakthroughs to patients remains slow and unreliable. Bringing a new drug to market takes 10 to 15 years and costs $2.6 billion on average. Even after FDA approval, too many eligible patients never receive treatment – caught in a system that wasn't built for the complexity of modern medicine. Most promising drugs never make it to market, and those that do reach only a fraction of the patients who could benefit. Forus is embedded into physician workflows, automating all steps between a clinical decision and a patient starting treatment — insurance authorization, financial assistance, and fulfillment routing — across every drug, payer, and pharmacy in the country, free for doctors and patients. Because we play an unprecedented role in moving prescriptions through the system, we provide life sciences companies unmatched insight into how medicines perform — enabling them to design better research, launch new drugs more effectively, and invest in harder-to-treat conditions. Our number one priority is scaling to market demand. We are looking for individuals who are high horsepower, high throughput, and hyper resourceful to help us unlock capacity and drive growth. We move fast and need to move faster.
