Why it matters
This proof is why Dewx is sold as an operated system.
I already know how to run client growth work. Dewx turns that operator loop into a private system: AI does the volume, every send waits for approval, and I stay accountable for the result.
30 minutes, with me, no pitch deck. If it's not a fit, I'll tell you on the call.
