Is LinkSure Network profitable in 2026?

No audited revenue has been disclosed since its 2015 Series A. Third-party estimates guess $4.4M to $33M annual revenue, but these are unconfirmed data-broker figures, not company statements, so profitability cannot be verified as of 2026.

Who owns LinkSure Network?

LinkSure Network is privately held, founded in 2013 by Chen Danian, who also co-founded Shanda Group and Zenmen Group. Its Singapore holding entity is LinkSure Network Holding Pte. Limited; no new investor or ownership change has been disclosed since its January 2015 Series A.

Could AI replace LinkSure Network's WiFi Master app?

No frontier AI lab or OS maker has shipped a cross-platform WiFi-password-sharing feature as of 2026, so LinkSure's crowdsourced hotspot database isn't directly displaced by AI. The bigger threat is cheap mobile data making the core use case irrelevant.

Who is LinkSure Network's biggest competitor?

Tencent (WeChat/QQ) and Baidu could absorb crowdsourced WiFi discovery into their super-apps with no structural barrier stopping them; they simply haven't, because China's free-WiFi-finding category cooled as 4G/5G data became cheap by the mid-2020s.

Has LinkSure Network raised new funding recently?

No. LinkSure's last disclosed funding was a $52 million Series A in January 2015 that implied a roughly $1 billion valuation. CB Insights data from December 2025 shows no subsequent round, IPO filing, or acquisition through 2026.

What is LinkSure Network's flagship product?

WiFi Master Key (also called WiFi Master), a crowdsourced WiFi-password-sharing app that by 2016 claimed 900 million cumulative users, 520 million monthly active users, and ranked as China's third largest app after WeChat and QQ.

On the recordSince 29 July 2026 · Checkable from through 2026 · Every call on the record Checkpoint: Any new funding round, IPO filing, or disclosed acquisition talk that reprices the company past its 2015 mark

The call

LinkSure built a huge free-WiFi app for a China that needed free WiFi; that China does not exist anymore, and no one has bothered to price the company since 2015.

LinkSure Network built an app that let people share WiFi hotspot locations with each other in areas where mobile data was expensive or hard to get. The company is no longer operating (inactive since late 2020) and has received no new funding in nearly a decade, yet it still has a $1 billion valuation that appears disconnected from reality. What made the service hard to replace was the database of WiFi locations people had crowdsourced and the app's top ranking in Chinese app stores, but cheap mobile data and faster 4G/5G networks in China have made the problem it solved almost irrelevant; even major companies like Tencent and Baidu chose not to copy it because the market for free WiFi discovery simply shrank. The only thing that could reset the picture would be if someone actually bought the company, took it public, or invested fresh money at a new price, which would signal whether the crowdsourced hotspot database still has hidden value.

Why

AI pressure: None apparent. No AI product targets crowdsourced WiFi password sharing directly; the problem itself faded as cheap mobile data spread. Could AI do the core job? Only partly.

Bigger players: Tencent and Baidu. Both could fold free WiFi lookup into WeChat or their own apps but have not bothered, since the market stopped being worth taking. Could a giant copy it? Yes, easily.

What protects it. A large historical hotspot database and old top-app-store ranking, but neither has produced a funding round or buyer in over a decade.

What would change this call

LinkSure Network announces a priced funding round or IPO filing by end of 2026. Would show the business still has investor backing and a valuation reset.
Tencent, Baidu, or Ant Group announces acquisition talks or a data-licensing deal with LinkSure. Would show its hotspot database still holds strategic value to a larger platform.
WiFi Master Key app disappears from major China app-store rankings or stops updating. Would confirm the product is fully wound down rather than dormant.

Key numbers

$52M Series A in Jan 2015 implied ~$1B valuation (2015-01)
520M monthly active users at 2016 peak (2016)
No funding, IPO, or M&A disclosure found since 2015 (2026)

Named risks

No priced funding event, IPO, or valuation update since January 2015, leaving equity effectively illiquid. Severity: high
Core use case of finding free WiFi is structurally eroded by cheap 4G/5G mobile data in China. Severity: high
No verifiable operational, financial, or product data since October 2020, making current state unassessable. Severity: medium
China's tightening data-privacy and cybersecurity law regime creates ongoing compliance exposure for apps collecting location/network data. Severity: medium
Founder Chen Danian's attention split across Zenmen Group's IoT, fintech, and space-tech ventures. Severity: low
