Investment accelerates Caju’s growth as global enterprises and government agencies adopt Caju’s platform to govern mobile and private messaging and unlock AI-driven insights
CHARLOTTESVILLE, Va., Oct. 26, 2026 /PRNewswire/ — Caju AI (“Caju”), the platform enterprises and government agencies use to govern business communications on mobile and private messaging channels, today announced a strategic investment from Arthur Ventures, an early growth capital firm that leads investments in B2B software companies. The partnership provides Caju with capital and strategic support for its product roadmap, AI capabilities, and continued global expansion.
Business conversations have moved from Email to WhatsApp, iMessage, SMS, and other mobile and private messaging channels. Under pressure from regulatory agencies, organizations spent years trying to capture those conversations. Caju was built for what comes next. The platform gives organizations policy-level control over how mobile and private messaging is used, captures communications compliantly, and applies an AI layer that categorizes messages, extracts themes, and assigns review priority, so compliance teams see what matters first and the business side gains visibility into channels it previously could not see.
Customers typically go live in weeks rather than months, and employees onboard in minutes while continuing to work the way they always have. This combination of governance, ease of use, and AI-driven insight has made Caju the choice of global enterprises and government agencies, including at the U.S. federal level, across financial services, life sciences, regulated industries, and the public sector. The company serves customers across North America, Europe, Latin America, and Asia, directly and through partnerships with leading archiving and compliance platforms.
The investment will support product development, including Caju’s AI capabilities, expand go-to-market and partner channels globally, and grow customer success resources as the company enters its next phase of growth.
“The industry spent five years getting mobile messages captured. Governing those channels well, and actually learning something from what is in them, is the harder problem, and it is the one we solve,” said Otavio Freire, Co-Founder and CEO of Caju AI. “Customers tell us two things: Caju was live faster than anything else they have deployed, and for the first time they can see what is happening in these channels.”
“We are excited to partner with Otavio and the Caju AI team as they help customers capitalize on the transition we’re seeing as business channels shift towards mobile and private messaging,” said Andrew Heim, General Partner at Arthur Ventures. “We are thrilled to provide growth capital to support their continued success.”
Williams Mullen served as legal counsel to Caju AI, and Gunderson Dettmer LLP served as legal counsel to Arthur Ventures.
