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.

78% of Americans live paycheck to paycheck and more than half have a poor credit score or no score at all. Without access affordable financial products, they resort to predatory products like payday loans, high-interest rate credit cards, and overdraft fees to make ends meet. After the short-term relief, these predatory products ultimately push people further into deeper cycles of debt. Pinwheel is building a fairer financial system by unlocking API access to payroll systems. Most people’s money can be traced back to a payroll system (e.g. ADP, Paychex, Gusto, etc). This makes payroll systems incredibly powerful because they 1) harbor valuable income and employment data and 2) sit at the top of the financial stack, with the controls that determine where your paycheck goes and how it gets split up before anyone else has a say. Unfortunately, the payroll ecosystem is largely closed and highly fragmented, disconnected from the banks, lenders, and service providers that could benefit from access to it. By building the pipes that aggregate and unlock these payroll systems, Pinwheel helps consumers access better, cheaper financial products when they need them most while also sparking innovation of new financial products.
