The approach
People don't buy Zapier.
They buy "no more admin."
Every review on this site starts with the outcome — the workflow problem you're solving — and works backward to the right tool. Not the other way around.
01 — Acquisition
Never lose a lead again
CRM for solo consultants, follow-up sequences, and lead magnets — built as a connected system, not a stack of disconnected apps.
02 — Onboarding
Client onboarding automation
Intake forms, scheduling, payments, kickoff notes, and automated next steps — triggered the moment a client signs.
03 — Delivery
AI workflow automation
Proposals, research, communication, and project management — so one person runs what used to take a team of three.
