Sewio: independent supplier assessment.
Sewio is a Czech UWB RTLS supplier with an open-platform philosophy and a strong industrial track record. This is TRACIO's independent assessment: where Sewio is the right call, and where Ubisense or Pozyx fit better.
Independent brief: we do not resell this supplier. How we assess suppliers.
Who they are
Sewio was founded in Brno, Czech Republic in 2014 and was acquired by HID Global in August 2024. It now sits inside HID's IoT Services business unit, which in turn belongs to ASSA ABLOY. The Sewio brand, product line and Brno engineering base continue.
Their stack covers UWB anchors (the Sewio anchor family), tags (multiple form factors including badge, asset, vehicle, ATEX-certified), the RTLS Studio platform for application building, and a comprehensive REST and MQTT integration surface.
They retain a healthy developer community and a partner network of industrial integrators, which is unusual for a UWB supplier. The HID acquisition adds global sales, support and supply chain behind that.

Where they're strongest
Sewio's strength is open-platform UWB at competitive cost, with a developer-friendly integration surface that lets in-house teams or SIs build applications rapidly.
Real-world deployments span automotive plants, logistics yards, mining and industrial safety. Documentation is genuinely useful (rare in this market), and the platform is configurable rather than opinionated: a strength for teams who want control.
Where they're not the right answer
Delivery still runs largely through partners rather than direct enterprise sales, so ask who actually installs and supports your site and hold them to the same accuracy gate as the OEM. The old objection that Sewio lacked a global services bench no longer holds under HID, but a corporate parent also means roadmap priorities set outside Brno, and closer alignment with HID's own identity and access portfolio.
The platform layer is less opinionated than Ubisense SmartSpace. That's a strength for builders, but means more application work for teams who want ready-to-run use-case software.
How they compare
Versus Ubisense: Ubisense has deeper automotive vertical software; Sewio has cleaner developer surface and competitive pricing. Versus Pozyx: similar UWB technology; Sewio has more mature platform and ecosystem.
Versus Quuppa: different technology (UWB vs BLE-AoA), different accuracy budgets. For an industrial RTLS deployment where in-house or partner integration capability exists, Sewio is firmly on the shortlist.
Positioning and tech stack
From a buyer’s architecture view, separate silicon or vehicle hardware from platform software, from workflow applications, from integrator delivery. Conflating those layers is how RFPs ask one supplier to be four things and then punish them for gaps that belong elsewhere in the BOM. Public product materials should be read as capability claims to validate on your floor, not as acceptance certificates.
TRACIO maps this supplier into the correct layer for your programme and scores it against alternatives in the same layer. We don't sell hardware, so our advice stays independent. Assessments stay independent of channel incentives.
Where it fits
Fit improves when your accuracy or throughput SLO, integration surface and support geography line up with the supplier’s centre of gravity. Ask for references that match your industry, site scale and radio or vehicle class. A glossy logo slide from an adjacent vertical is weak evidence. Pilot on the real process with production interference present.
Also confirm whether success depends on a partner SI. Many credible platforms ship through channels; that is fine if the partner is named, contracted and measured against the same accuracy gate as the OEM.
Where it does not fit
Under HID, roadmap priorities are now set outside Brno, closer to HID's own identity and access portfolio.
Walk away or dual-source when your SLO sits outside the proven accuracy band, when procurement origin or risk policy blocks the supplier, when services bench is thin in your region, or when the commercial model forces platform modules you will never operationalise. An accurate “not fit” early is cheaper than a stalled pilot.
Alternatives to shortlist
Keep at least one alternative in the same layer through design review so pricing and roadmap pressure stay real. For hybrid programmes, expect complementary suppliers across layers (for example RAIN identity at docks plus UWB on vehicles, or Wi-Fi analytics plus BLE-AoA in precision zones). See our comparisons for head-to-heads that match common shortlists.
Procurement notes
Write accuracy or performance SLOs per zone before you request quotes. Require independent RF or site-design review rights, a live acceptance test method, tag or robot battery and refresh assumptions, integration scope into MES/WMS/EMR, and a five-year TCO workbook that separates hardware, licences, install PMO and application work. Ban vanity metrics that only appear in empty-lab demos.
Commercial diligence should cover support hours for your geographies, spare-parts lead times, firmware cadence, data residency, exit clauses for raw data access, and whether professional services are OEM or partner delivered. TRACIO helps you choose AGVs and AMRs and plan fleet management; we do not sell robots.
If this supplier clears the gate on your constraints, we will say so. If another clears it cheaper at equal SLO, we will say that too. Independence is the product.
Frequently asked questions
What accuracy does Sewio deliver?
UWB is usually the most precise of these options. The accuracy you get depends on your site, and we confirm it in the survey. Real-world performance depends on anchor density and RF environment, validated by site survey at gate 1, regardless of supplier.
Is Sewio suitable for hazardous-area deployments?
Yes, they offer ATEX/IECEx-certified anchors and tags for oil-and-gas, mining and chemical environments. We verify the specific certification class against your zone requirements during stage 1.
How does Sewio's pricing compare to Ubisense?
Generally more competitive at the infrastructure layer; Ubisense is at the premium end. Total cost can converge once application development effort is factored in. We model both in stage 1 TCO.
Does Sewio integrate with SAP and other enterprise systems?
Yes, REST and MQTT surfaces work cleanly into SAP EWM, Manhattan, Blue Yonder and other enterprise systems. The integration is typically built by your SI or our build-and-integration team, not by Sewio directly.
