Different stages of development need different resources
Early research may need specialist equipment and time to test whether an idea is technically possible. A working prototype introduces other questions, including whether people can use it and whether it can be produced consistently.
Further context
Funding rounds are one way businesses organise resources around those stages, although a round name alone says little about technical maturity. Comparing the work already completed with the work still required gives a clearer picture than the size of a funding announcement.
