About ZKSCool
Ten years at the frontline of cold chain IoT.
ZKSCool builds AIoT cold-chain technology for partners who choose innovation over legacy. Our hardware and zTMS cloud platform monitor 500,000+ nodes across 60+ countries — protecting medicine, vaccines, blood, and food for over 10,000 institutions worldwide. In 2025 we closed our Series A and broke ground on a new medical-device manufacturing base in Anhui — investment for the next decade of AIoT in healthcare.

What drives us
Mission, vision, and the values we choose people for.
Most cold-chain vendors sell into the industry. Over ten years, ZKSCool has been invited to help write its rules.
2015 → 2019 — building the foundation.
ZKSCool was founded in Shenzhen with chip-design expertise brought in from Norway, and joined the founding membership of China’s national LPWAN industry alliance and the GS1 Hong Kong supply-chain standards body in the same year.
By 2018, our cold-chain monitoring won the Walmart partnership — the inflection point that took us from pharma into food cold chain at scale. The next year, we released the industry’s first 5G cold-chain IoT gateway and were selected for the Tencent AI Accelerator.
2021 → today — asked to help write the rules.
In 2021, ZKSCool was chosen to lead the drafting of China’s cold-chain LPN (low-power network) technology standards, and partnered with Japan’s Marubeni to take that architecture into international markets. Two years later, we co-authored the national pharmaceutical logistics standard.
In 2024, the Ministry of Industry and IT designated us the leader of its ‘Spark Chain Network’ traceability program — responsibility for 500,000+ cold-chain nodes across 10,000+ institutions. That’s the arc: operator → recognized vendor → author of the standards our industry operates by.
Why partners choose us
Built for partners who choose innovation — across pharma, biotech, life sciences, and food supply chain.
Cold chain today looks very different from cold chain a decade ago. Cell therapy, gene therapy, mRNA, GLP-1, and personalized medicine all depend on temperature integrity that scales with their pace of change. Modern food supply chains face the same evolution — multi-zone warehouses, last-mile delivery, traceability across borders. Our customers want partners who keep pace with that evolution — partners building on contemporary IoT architecture for today’s cold chain reality.
ZKSCool was built IoT-native from day one. Our self-developed interBow LPWAN reaches places WiFi can’t. Our zTMS cloud platform delivers real-time visibility, audit-ready records, and the integration depth procurement teams need across hardware, software, and service. We invest constantly in staying at the frontline of cold chain IoT — our 2025 Series A is funding the next decade of AIoT for healthcare and food safety alike.
If you measure a partner by contemporary architecture, reliability under load, and productive integration with the systems you already use — that is the partnership we are built for.
Market context: cell & gene therapy cold chain logistics is projected to grow from $2.19B (2025) to $8.06B (2034) — Towards Healthcare 2025. 3,063 CGT candidates in active development as of 2024.
500,000+ nodes monitored. Across pharmacies, hospitals, labs, and distribution networks — wherever temperature integrity matters.
