What's a DPO?
DPOs are specifically designed to let small businesses access the public capital markets with less cost and complexity than is involved in IPOs. DPOs typically raise amounts of less than $1 million, but you can raise up to $25 million with DPO under certain circumstances. You can also advertise and promote the sale of your own stock if you hold a DPO, something other public companies are forbidden to do.
