Proton
Automate orders. Protect your margin.
What is Proton
Proton automates the operational layer of B2B distribution sales — pulling data from emails, PDFs, and spreadsheets to draft orders and quotes, match SKUs, and enrich product catalogs without manual entry. It is built for RevOps teams and Account Executives at mid-market and enterprise distributors who need pipeline visibility, pricing intelligence, and e-commerce growth tools in one place. The standout capability is its ability to analyze margins and competitive signals to recommend optimal prices per product and per customer — a function most generic CRMs leave entirely to spreadsheets. Proton integrates with ERP, CRM, PIM, and Infor environments, but it is purpose-built for distribution verticals, meaning teams outside that industry will find limited fit and likely need to look elsewhere.

Vanderbuild take
Proton is a vertical CRM built specifically for distribution — if your RevOps or AE team sits inside a wholesale or industrial distribution business, this covers more of the sales workflow than a horizontal CRM ever will. On the agentic side, Proton carries a Capable rating with a live API, meaning you can wrap it into your own MCP orchestration layer or connect it to agent workflows without too much friction — though MCP-native status is unconfirmed, so expect some integration work before it's agent-callable out of the box. Pricing is not publicly listed, which typically signals enterprise procurement cycles and custom contracts — budget accordingly and don't expect a self-serve trial. The honest constraint here is vertical lock-in: Proton's depth is its strength, but if your business spans industries beyond distribution, you'll be forcing a fit that isn't there.
