Polar for LinkedIn lets founders, salespeople, and recruiters hand profile search, candidate review, and outreach drafting to Polar, an AI browser that works inside the LinkedIn account they already use. A user describes the people they want, and the agent filters by industry, company size, job title, and location, checks experience when the task is a hire, and writes connection messages. The company says Polar took 1 million actions on LinkedIn for its users in the 90 days before this launch, which is why the release packages those jobs as saved workflows that can run again on a schedule. Users can watch each step and take over at any time. The launch shows the agent finding customers from recent posts, building a shortlist for a sales hire, and preparing connection requests for a daily set of industry contacts, with the drafted messages gathered in one list. Polar is built on Chromium, so it operates inside accounts the user is already logged into, and it can keep working on tasks that run for minutes or for many hours. The company was founded by Kevin Jiang, who worked on Comet at Perplexity, with Vishaal Ram and Howard Zhong. It raised a $5.7 million seed round led by Madrona in July 2026.
