Xingsai Bio

What Xingsai Bio does

Xingsai Bio (Qingdao Xingsai Biotechnology Co., Ltd., 星赛生物) is a privately held Chinese life-science instrumentation company founded in 2014 that develops single-cell analysis instruments, proprietary reagents and consumables, and supporting data software. The company is headquartered in Qingdao, China, with 51-100 employees, and was co-founded by researchers Xu Jian and Ma Bo from the Qingdao Institute of Bioenergy and Process Research (QIBEBT) of the Chinese Academy of Sciences. Xingsai Bio's commercial offering is built around its proprietary meta-Raman group (元拉曼组) technology, which enables label-free, non-destructive single-cell metabolic function analysis, imaging, sorting, sequencing, and cultivation. The product portfolio includes six core instruments — FlowRACS (high-throughput flow Raman sorter), RAMS (Raman microfluidic single-cell sorter), RACS-Seq (Raman-activated sorting coupled with sequencing), DCP (Digital Cloning Picker), EasySort Compact, and RamanEye — supported by specialized reagent kits, software (RamEX, RamDB, RamLIS), and technical services. Cumulative instrument sales are stated as approaching 10 million RMB across university and research institute applications.

The company monetizes primarily through one-time instrument sales, recurring reagent and consumable purchases, technical services, and subscription/recurring software access. Go-to-market is sales-led and direct, centered on academic and research institutions in China, with a stated priority to expand into industrial and international markets following the January 2026 A++ financing round of approximately 100 million yuan. Customer applications span four primary segments: life-science research and academia, synthetic biology and industrial fermentation, precision medicine and clinical diagnostics, and environmental monitoring and agriculture. Notable customers include CAS-QIBEBT, Tsinghua University, China Ocean University, Peking Union Medical College Hospital, and — as of March 2026 — the UCSD Microbiome Innovation Center. Distribution relies on direct sales, academic conference participation, scientific publication-driven KOL engagement, and the company's Xingsai Lectures training platform. The company has raised approximately 230M+ RMB across Pre-A (April 2022), Series A (December 2023), an additional 2024 round, and A++ (January 2026), with participation from Hengxu Capital, Zhongke Yucheng Investment, Zhejiang Merchants Capital, Shandong Financial Capital, Kweichow Moutai, and Neovision Capital.

Core offering

Xingsai Bio develops and manufactures proprietary single-cell analysis instruments based on its meta-Raman group (元拉曼组) technology, including high-throughput flow Raman cell sorters (FlowRACS), microfluidic single-cell sorters (RAMS), optical-tweezers Raman sorters (RACS-Seq), and digital clone pickers (DCP), supported by specialized reagent kits, consumables, and spectral analysis software. The company also offers single-cell Raman imaging, sorting, sequencing, and cultivation technical services for life science researchers and industrial bioprocess users.

Product overview

Xingsai Bio (星赛生物) is a life sciences instrumentation company specializing in single-cell metabolic function analysis and sorting solutions. The company offers an integrated platform built around proprietary meta-Raman technology (拉曼组/元拉曼组), encompassing three core instrument product lines: FlowRACS for high-throughput flow-based Raman sorting, RAMS for microfluidic single-cell selection, and RACS-Seq for optical tweezers-based sorting coupled with sequencing. Supporting these instruments is a comprehensive portfolio of reagent kits for soil microbial analysis, cell enrichment, and functional screening, complemented by data software (RamEX, RamDB, RamLIS) for spectral analysis and instrument control. Technical services provide single-cell Raman imaging, sorting coupled with sequencing/cultivation, and microbiome-level single-cell analysis. The product ecosystem addresses applications in synthetic biology, industrial fermentation, precision nutrition, cell drug development, clinical diagnostics, and environmental monitoring.

Broad incumbents

• 10x Genomics: Global leader in single-cell sequencing and spatial omics. While primarily genomics-centric (Chromium, Visium, Xenium), 10x is the dominant commercial reference for single-cell analysis workflows and the natural comparator for any company selling into the same academic and pharma customer base as Xingsai Bio.
• BD Biosciences (Becton Dickinson): Established leader in flow cytometry and cell sorting (FACSMelody, FACSDiscover S8 with CellView image technology). BD's installed base in academic and clinical labs is the incumbent Xingsai competes against in flow Raman-activated sorting, with significantly larger commercial reach and brand trust.
• Beckman Coulter Life Sciences: Major flow cytometry and cell sorting provider (CytoFLEX, MoFlo Astrios, CellMek). Comparable to Xingsai in serving academic and industrial cell-sorting use cases, with established global sales channels that Xingsai would need to match for industrial-fermentation expansion.
• Bruker Cellular Analysis (formerly Berkeley Lights): Acquired Berkeley Lights' Beacon single-cell functional screening platform and now sells optofluidic cell-sorting instruments. Directly comparable in workflow (live single-cell functional screening and selection) and target customer (antibody discovery, cell therapy, synthetic biology).
• HORIBA Scientific: Major supplier of Raman, fluorescence, and particle characterization instruments (LabRAM, XploRA PLUS). Comparable as a Raman instrument vendor serving research and industrial customers; HORIBA's broader portfolio gives it scale advantages in commercial channels but less focus on live-cell functional sorting.
• Sartorius: Global bioprocessing leader with strong presence in cell line development, fermentation monitoring, and cell therapy. Relevant as Xingsai expands RAMS into industrial fermentation and cell drug development workflows; Sartorius represents the kind of strategic partner or acquirer that could distribute Xingsai's bioreactor Raman monitoring technology.

Direct peers

• Cytek Biosciences: Spectral flow cytometry specialist (Aurora, Northern Lights) that brought spectral unmixing into mainstream cell analysis. Closely parallels Xingsai's positioning in label-free, spectral-based single-cell characterization; both target researchers seeking richer per-cell functional data than conventional flow cytometry provides.
• Renishaw: UK-based manufacturer of Raman spectroscopy instruments (inVia, RA802) widely used in academic and industrial labs. The closest direct technical competitor to Xingsai's Raman spectroscopy core technology, though Renishaw does not offer integrated Raman-activated cell sorting products like FlowRACS.

Emerging players

• Mission Bio: Single-cell genomics platform focused on multi-omics and targeted DNA sequencing (Tapestri). Adjacent competitor in the single-cell analysis market, particularly relevant to Xingsai's RACS-Seq sequencing-coupled sorting offering, though Mission Bio lacks Raman metabolic phenotyping capability.
• NanoCellect Biomedical: Developer of microfluidic cell sorting instruments (WOLF Cell Sorter) targeting gentler, lower-pressure sorting of sensitive cells. Comparable in philosophy (microfluidic + gentle single-cell sorting) and in serving researchers seeking alternatives to high-pressure FACS systems — relevant overlap with EasySort Compact and RAMS.
