Ask HN: What is the best way to find product market fit for US market

I will be visiting the US for a month in May to understand if there is space for our product. Will be attending TieCon and a couple of events. We are a cloud communications startup and we have a couple of successful products in India. We are currently doing $4 Million ARR with Indian customers. Growth is linear now and team has stabilized. So we wanted to check if we can crack the US market next. We have built a custom product for the US market(getkookoo.com). Wanted to check if there is a product market fit. We are in the space of Talkdesk and Amazon connect. What are the best ways to do that? Planning on attending events. Meeting some CRM partners. Any other suggestions? Will be in the bay area in the month of May. Would love to meet fellow entrepreneurs. Coffee on me :)
