We have developed a go-to-market strategy, designed and launch a splash page to gauge new signups, have completed the wireframing of our UI mockups, and user story flows.
In regards to verifying product-market fit, we've acted as brokers for premium car transactions in Los Angeles. To name a few transactions, we've dealt with Ferrari Californias, Bentley Continentals, and even Lamborghini Aventadors over Facebook/in-person interactions.
