In the early days of 8base, our team made a very conscious decision to put off launching a free-tier. Unlike many software companies, we looked at a free-tier as something that the product had a lot of growing up to do in order to support it. Why? Promising someone that something is "free forever" is a really big promise! Especially when a product is young and its company hasn't proved that – when it does grow up – users will experience enough value to eventually pull out their wallets.
