Is Hosjoy still a $1 billion unicorn in 2026?

Hosjoy's $1B valuation dates to its Series C-II round closed October 18, 2018, per CB Insights. No new funding round has been disclosed since then, so the unicorn tag is roughly eight years stale with no confirmed current mark-to-market valuation.

What does Hosjoy do now compared to when it started?

Hosjoy began in 2009 in Nanjing selling consumer smart-home hardware like HVAC and water purification via stores and an app. It has since pivoted to B2B 'smart building digitalization' branded Orange Smart Cloud, targeting real-estate developers and construction firms.

Who owns Hosjoy and is it linked to a public company?

Hosjoy is privately held and described as a subsidiary of Five Star Holding Group. In March/May 2023 its engineering subsidiary, Nanjing Hosjoy Engineering Technology, was sold to publicly listed Huitongda Network for about RMB 504.3 million (~$73.3M), per vendor-sourced reporting.

Could AI replace Hosjoy's smart building business?

Hosjoy's higher-value digital-twin and building-operations layer overlaps directly with AI-driven predictive maintenance and energy optimization platforms from Alibaba Cloud and Huawei Cloud. No independent evidence confirms Hosjoy has shipped defensible proprietary AI capability as of 2026.

Who is Hosjoy's biggest competitor?

CB Insights lists Hollysys and Perenio as direct competitors, while Hosjoy also faces mass-market consumer smart-home commoditization from Xiaomi's ecosystem and larger-scale building automation incumbent Siemens in its newer B2B segment.

Is it risky to join Hosjoy as an employee in 2026?

No current headcount data exists; CB Insights lists 'no job info.' Hosjoy already divested its engineering subsidiary to Huitongda in 2023 and has raised no disclosed funding since October 2018, consistent with capital stall.

Not much stands between this business and its pressures.

On the recordSince 29 July 2026 · Checkable from H1 2026 · Every call on the record Checkpoint: Huitongda's next public filing on further Hosjoy asset absorption or reverse-merger terms

The call

Hosjoy sits on an aging 2018 valuation with no fresh funding, a divested core subsidiary, and no visible AI product, while Chinese property developers, its main customers, remain in a multi-year downturn.

Hosjoy sells software to help Chinese real-estate developers manage apartment buildings and facilities. The problem is that bigger companies like Siemens and Xiaomi can build the same thing cheaper and faster, and there is no sign Hosjoy has locked in customers or built technology that competitors cannot copy. The one thing that could change the picture is if the Chinese housing market stabilizes and developers start spending money again on building management tools, which could give Hosjoy room to prove it has something worth keeping.

Why

AI pressure: Alibaba Cloud and Huawei Cloud AI building-management platforms. Cloud giants are building AI predictive-maintenance and digital-twin tools for buildings that could replace Hosjoy's manual smart-building offering. Could AI do the core job? Yes, likely.

Bigger players: Siemens and Xiaomi/Aqara ecosystem. Siemens already sells building automation to developers and Xiaomi's ecosystem has commoditized the consumer smart-home hardware Hosjoy started with. Could a giant copy it? Yes, easily.

What protects it. Backing from parent Five Star Holding Group and an existing base of 300,000+ connected homes give it some standing relationships to lean on.

What would change this call

Hosjoy announces a fresh priced funding round in 2025-2026. Would show investors still value it near or above the 2018 $1B mark.
36Kr or LatePost report on Orange Smart Cloud developer wins. Would show the B2B pivot is gaining real, verifiable customers.
Huitongda files further Hosjoy asset absorption or reverse-merger disclosures. Would confirm deeper financial dependence and loss of independence.
