What's the deal? Caju AIDealroom has a profile for this one. Try Dealroom → has secured a growth-equity investment from Arthur VenturesDealroom has a profile for this one. Try Dealroom →, the companies announced on October 26. The firm led the round; terms were not disclosed. Charlottesville-based Caju sells software that enterprises and government agencies use to govern business conversations on mobile and private messaging channels.
What does Caju do? Its platform gives organisations policy-level control over channels such as WhatsApp, iMessage, and SMS, captures messages for compliance, and applies an AI layer that categorises them, extracts themes, and flags what review teams should see first.
What's the money for? Caju will spend the capital on product development, including its AI capabilities, global go-to-market and partner channels, and customer success resources.
Why now? "The industry spent five years getting mobile messages captured," said co-founder and chief executive officer Otavio Freire. "Governing those channels well, and actually learning something from what is in them, is the harder problem, and it is the one we solve."
Caju serves customers across North America, Europe, Latin America, and Asia — in financial services, life sciences, and the public sector, including at the US federal level. It is SOC 2 compliant and works directly and through archiving and compliance partners.
What's the backdrop? Caju's last disclosed raise was a $3 million seed round in June 2024, backed by Grotech VenturesDealroom has a profile for this one.

Arthur Ventures, which leads deals in B2B software companies outside Silicon Valley, now provides what it called "growth capital to support their continued success," per general partner Andrew Heim.
The signal: The customer-communications AI category is drawing far bigger cheques — Parloa raised $350 million and Decagon $250 million in January 2026. Without disclosed terms, Caju's position in that competitive field is harder to gauge, but the deal signals investor appetite for the compliance side of the messaging shift.
