Dev Shop Size
Large AI Development Companies
Large AI dev shops can staff parallel workstreams and draw on a bench of engineers across specialties, at the cost of more risk that the team you met in the sales process is not the team that builds. Ask who exactly will be on your project and how continuity is handled when people rotate.
