Modjoul

What it does

Modjoul sells the SmartBelt, a belt-worn wearable that measures bending and twisting, including angle, duration and count, and vibrates to warn the wearer about risky movements ^[1]. Its white paper says the haptic alert can trigger on bends beyond 60 degrees and that the belt also reports heat index and noise above 80 dB ^[2]. HaloGuard adds ultra-wideband modules and driver displays on forklifts so drivers and pedestrians get proximity alerts ^[3]. Data flows to a dashboard covering lumbar risk, lone worker alerts, temperature warnings, PPE compliance and asset tracking ^[4].

Who it is for

Modjoul lists manufacturing, warehouse and logistics, construction, healthcare, retail, hospitality, agriculture, transportation and mining as applicable industries ^[1]. It also works with insurance carriers and resellers, and says its founders are former insurance executives ^[5]. Amazon describes the company as founded in 2016 and based in Greenville, South Carolina ^[6], where its office is listed ^[7].

How it is deployed

Workers wear the belt during shifts, and belts are charged in a multi-unit charging station. The starter bundle includes 10 belts, a ten-unit charger and a software license, listed from $4,500 ^[1]. HaloGuard needs forklift modules and driver alert displays in addition to the belts ^[3]. Modjoul says nearly every client starts with a pilot, followed by analysis, budgeting, reporting and planning for API integration with client systems ^[8]. Its privacy policy says the organization chooses which metrics are collected, that the belt can collect location and motion data, and that Modjoul generally deletes customer data within 60 days of collection ^[9].

Notable public customers and coverage

The Amazon Industrial Innovation Fund named Modjoul among its first investments in April 2022 ^[6]. In April 2025 Solaia Capital Advisors announced an investment of undisclosed size to fund growth and an AI Manager product ^[10]. Modjoul's case study on Elevate Textiles Plant 21 in Gastonia, North Carolina, reports a 73% cut in risky bends and an 85% year-over-year drop in injury frequency; these are vendor-reported figures ^[11]. Australian insurer EML published results from a pilot with Mitolo Family Farms using the belt: 25 users, a 60% reduction in bends over 60 degrees and no time-lost injuries during the pilot ^[12].

Things to ask in an evaluation

• How was bend angle measurement validated, and against what reference?
• What security controls, certifications and data processing terms apply to worker data?
• How were the case study results measured, and was there a comparison group?
• Which EHS or warehouse systems can receive data through the API today?
• How are individual movement scores used, and can they affect discipline?
• Who handles charging, cleaning and lost belts?

Our take

Strengths: Pricing is public, with a 10-belt starter bundle listed from $4,500 ^[1]. An insurer, EML, published pilot results using the belt ^[12]. One belt covers ergonomic feedback and forklift proximity alerts through HaloGuard ^[3].

Watch-outs: We found no published validation of the belt's movement measurements, and outcome figures come from vendor case studies or a small pilot without a control group ^{[2] [11] [12]}. Security is described only in general terms in the privacy policy, with no published DPA or certification claim ^[9]. Named integrations are not listed; API work is planned during pilots ^[8].

Best fit: Warehouse, distribution or manufacturing sites with manual handling and forklift traffic that want to test belt-based ergonomic coaching through a small pilot, possibly with an insurer.
