    I am a tokenomics consultant with over 220+ projects of experience, which in turn have raised over 1 billion USD in funding. I focus on designing sustainable token economies for companies of all scales and businesses of all types. Too many projects in the crypto space follow a copy/paste approach to their tokenomics that can be devastating for the project in the long run. On the other side I believe in data-driven sustainable tokenomics design that adheres to the best practices in game theory and economics. I have also worked as a tokenomics advisor for multiple projects over long periods of time (2+ years) and have operational experience in being the CPO for a fully decentralized and permissionless crypto insurance project.
