Company Description
Founded in 2015, Plume develops a software-as-a-service platform for Internet Service Providers (ISPs) that focuses on subscriber experience and cloud-managed Wi-Fi. The company's technology is currently used by more than 450 ISPs and supports over half-a-billion devices. Its core offerings, including the hardware-independent OpenSync framework, use AI to manage and optimize network performance, provide security, and deliver smart home services. Headquartered in Palo Alto, California, with an international office in Ljubljana, Slovenia, Plume was founded by Fahri Diner. The company has raised $692.7 million in total funding and had a market valuation of $2.6 billion as of October 2021.
A recent development for the company was its 2024 acquisition of Sweepr Technologies, a firm specializing in AI-orchestrated customer care. The acquisition aims to integrate real-time network intelligence with automated customer support actions, and Sweepr's co-founders joined Plume's leadership team as part of the deal. Plume is also working to support emerging connectivity standards, having collaborated with Zyxel Communications at CES 2026 to showcase a cloud-managed 5G Fixed Wireless Access (FWA) solution featuring Wi-Fi 7. Future plans include the global commercialization of the Sweepr AI platform and the extension of its OpenSync framework into 5G FWA environments to provide consistent policy control across hybrid networks.

Frequently Asked Questions
Joining Anduril as an employee is another way to acquire equity, typically through stock options included in compensation packages.
Is Plume worth joining?
Answering this depends on your personal career goals and belief in the company's long-term vision. To help evaluate the financial upside, you can use a platform like Prospect to forecast the potential value of your equity compensation.
What should I do with my Plume stock?
Managing private stock is complex, involving decisions on when to exercise options and how to minimize taxes. Platforms like Prospect can help you build a customized strategy based on your specific financial situation and equity holdings.
Can you sell Plume stock?
As Plume is a private company, its stock is not traded on a public exchange, but selling is possible during specific events like tender offers or on secondary markets. Tools from Prospect can help you navigate these opportunities and determine which shares are the most tax-optimal to sell.
How can I find the value of my Plume stock?
The official value is determined by a 409A valuation, but the potential future market value can be harder to predict. You can use Prospect’s predictive models, which analyze data like funding rounds and market trends, to project a range of likely outcomes for your equity.
What is Plume's equity worth?
The value of equity in a private company like Plume is not a fixed number and can fluctuate based on performance, funding, and market conditions. To understand the potential range of outcomes, platforms like Prospect use machine learning to forecast future value based on data used by top VCs.
What is Plume's stock ticker symbol?
Since Plume is a private company, it is not listed on a public stock exchange and therefore does not have a stock ticker symbol. Ticker symbols are only assigned to companies once they go public through an initial public offering (IPO).
Can I buy or sell Plume stock?
You can typically “buy” stock by exercising your vested options, and you may be able to “sell” shares during company-approved liquidity events like tender offers. Services like Prospect provide tools and strategies for both exercising options and selling shares in a tax-optimized way.
What is the criteria to buy or invest in Plume stock?
Investing in a private company like Plume is typically limited to accredited investors during funding rounds or employees who receive equity as compensation. If you are an employee with stock options or RSUs, platforms like Prospect are designed to help you manage that equity.
