Oak Lands $60M Seed Round Led by Greylock to Replace the Scattered Corporate Intranet

Oak, a company building an all-in-one intranet and employee experience platform, has raised $60 million in seed funding. The round was led by Greylock. The company announced the funding on July 15, 2026.

The platform is designed to serve both frontline and desk-based workers. It combines internal communications, employee recognition, onboarding tools, pulse surveys, and operational resources into a single mobile-first system. Oak’s website highlights AI-driven personalization that tailors message delivery for each employee, along with multi-channel reach through push notifications and digital signage. Analytics dashboards let managers track engagement and survey results in real time.

The cash infusion will be used to expand Oak’s product capabilities, which already include an AI layer branded as Oak AI, a dedicated mobile app, and integrations with tools like Microsoft 365. The company also plans to deepen its reach across industries including healthcare, retail, hospitality, manufacturing, and financial services.

Oak enters a crowded field of workforce communication tools but differentiates itself by targeting organizations with large distributed workforces. Its customer list includes Burger King, Aldi, Five Guys, ITV, River Island, Sevita Healthcare, and Zigup. The company publishes specific outcome metrics tied to these deployments: Burger King saw a 32 percent reduction in turnover among hourly paid crew in new sites within three months, Sevita achieved 84 percent adoption across 42,000 employees, and Five Guys reported a 97 percent adoption rate.

The platform’s feature set spans employee communications aimed at replacing scattered updates with targeted messaging, retention tools that combine recognition and support to reduce churn, structured onboarding flows personalized by role and location, and employee voice surveys with analytics to gauge sentiment. Oak’s pitch centers on unifying these functions to create what it calls a high-performance culture, rather than stitching together separate point solutions.

With $60 million in seed capital, Oak is positioned to accelerate product development and go-to-market efforts at a scale unusual for a company at this stage, reflecting both the size of the opportunity in the employee experience market and the conviction of its lead investor.
