I have worked in multiple b2b startups and one of them was reasonably successful. Based on what I saw, split ratio changes as the startup matures. Earlier we had mostly monthly sign ups. monthly >> annual. As we hired a bigger sales team and created incentives for them to close on annual contracts annual brought in a significant revenue. More like monthly ~ annual.
It also was based on the market type we went. Initially it was small b2b businesses (employee size of around 50k). Once we started moving up market, the contract amount and deal size increased.
