Overview

Assembly, rebranded from Copilot in September 2025, gives professional service firms a branded client portal paired with an AI-powered CRM to centralize client communication, files, forms, and invoices. Marlon Misra and Neil Raina founded the company, originally as Copilot, in 2020, and it is headquartered in New York City.

The AI Assistant draws on full client context, including history, notes, custom fields, and past invoices, to draft replies, summarize message threads, create tasks, and prepare invoices automatically. The rebrand from Copilot came after Microsoft Copilot and GitHub Copilot turned the word into generic shorthand for AI assistants, making the original name hard to find in search and recommendations.

Consulting firms, legal practices, marketing agencies, and financial advisors managing scattered client communication are the target users, with the company reporting more than 1,000 businesses and 1 million clients on the platform. Plans start at $39 per month for the Starter tier, with a 14-day free trial and no permanent free plan.
