Our blockchain-enabled platform allows you to unlock the massive value locked away in your existing reputations. You can link any of your websites, for example Airbnb for your guest score or Upwork for your reviews as a gig worker. You are empowered to reveal these verified reputations, over and over again, instantly proving you are trustworthy as part of any application or signup process, for example to secure a tenancy agreement, a loan, or a job as an Upworker. We’ve built Reputationaire on a blockchain giving you ownership, security, privacy and control. Via your private trust vault, you and only you, have ownership of not only your data but more importantly the reputation that you've invested time carefully building. And you'll be able to take your reputation with you between services, so you'll never have to start from zero stars when joining a new service. We help overcome negative bias and lack of trust with the option to remain anonymous yet trusted.

Our approach is rigorous and pragmatic, driven by technological expertise and analytics informed by real-world experience. We value employees who love to learn and have the tenacity, curiosity and willpower to contribute to our continuing success. We are a small but passionate team, dedicated to enhancing and refining our tried and true methods as we commit to our ongoing growth and performance.
