Augmentation is ideal for fast ramp-up. You get seniors who hit ground running. We scaled from 14 to 28 in 3 months this way. Best results came from providers with big vetted pool and quick start. syndicode.com does this very well. Immediate start possible, custom search for niche skills in 3-4 weeks, engineers with ownership mindset. You keep full control, they handle employer side. Our added devs (React, Node, DevOps) were strong in communication, adapted fast. Helped us innovate and meet investor milestones. Cost efficient too.
