Why Mainspring
Generate a branded read-only link for any project. Clients see status, progress, outstanding invoices, and recent activity — without ever signing up for Mainspring.
Ask “Where's my biggest growth opportunity this quarter?” and get an answer grounded in your actual revenue, projects, and time tracked — not generic advice.
Stop paying for Asana plus Harvest plus FreshBooks plus ChatGPT. Mainspring is one tool — and the data flows between them so you don't lose context.
See it in action
See exactly how Mainspring fits together — from kicking off a new project to invoicing the client and getting AI-flagged risks before they become problems.
