What Carin does

Carin is a Netherlands-based direct-to-consumer digital health brand operated by LifeSense Group from the High Tech Campus in Eindhoven. The company builds a non-invasive pelvic floor training system for women experiencing urinary incontinence — particularly postpartum recovery and general pelvic floor weakness — combining a miniaturized Bluetooth sensor embedded in absorbent underwear with a companion mobile app available on iOS and Android. The sensor automatically detects and quantifies urine leaks throughout the day, syncs data wirelessly to the app, and feeds a personalized 10-minute daily exercise program with progress tracking and activity correlation, with the company reporting that users typically regain 80–100% control within 3–8 weeks of consistent use.

Carin's product portfolio comprises three SKUs: the Carin Pro Sensor & Underwear set at €288.88 (the complete smart training system with two absorbent underwear), standalone Carin Underwear at €25.88 (reusable period and leak protection without the sensor), and a 10-week Carin Set rental at €38.88 designed as a try-before-you-buy entry point. Revenue mechanics blend one-time hardware sales with a recurring rental/subscription stream and a 10% ambassador loyalty discount that incentivizes repeat purchases. Distribution is entirely direct-to-consumer via carinwear.com with global shipping (free within the Netherlands) and mobile app stores, supported by content marketing through educational blog posts, customer success stories, and an email newsletter.

Carin sits within the broader LifeSense Group portfolio alongside the Oopsie Heroes children's health brand, both founded in 2011 by Dr. Valer Pop, Julia Veldhuijzen van Zanten, and Mitsugu Yoneyama after the founders witnessed a family member's struggle with urinary incontinence. The company is privately held, has no disclosed external funding rounds, and competes in the global smart/biosensor underwear market valued at US$638.8 million in 2023 and projected to reach US$1.5 billion by 2034 at a 7.9% CAGR. The competitive position rests on proprietary sensor-underwear integration, non-invasive form factor, and continuous data-driven personalization rather than enterprise contracts or regulated clinical channels.

Core offering

Carin sells a wearable pelvic floor training system that combines a mini Bluetooth sensor embedded in absorbent underwear with a companion smartphone app. The sensor automatically detects and measures urine leaks throughout the day, syncing data to the app which delivers personalized 10-minute daily pelvic floor exercises and tracks recovery progress. Supporting offerings are washable standalone absorbent underwear and a 10-week rental trial of the full sensor set.

Product overview

Carin is a pelvic floor training system comprising three main products: the Carin Pro Sensor & Underwear (the core professional set combining a wearable sensor with absorbent underwear and a companion mobile app for personalized training), Carin Underwear (standalone protective absorbent underwear for menstrual and urine leak protection), and the Rent Carin Set (a 10-week rental option of the Pro Set for trial use). The system works by having users wear the sensor-equipped underwear, which connects via Bluetooth to the Carin training app on their smartphone or tablet to track exercises, measure leaks, and provide personalized pelvic floor training programs.

Scale indicators5 records

Recent moves6 records

Expansion highlights5 records

Emerging players

• Cora: Cora sells organic period care and leakproof underwear, with a strong content and brand presence in women's health. It overlaps Carin's reusable leak underwear offering and shares the female-focused wellness positioning.
• Joylux: Joylux makes vFit and other connected women's wellness/intimate health devices for pelvic floor and menopause. It overlaps Carin's target customer with adjacent device-based solutions and emerging brand presence in women's intimate health.
• Lily Bird: Lily Bird delivers postpartum recovery kits and incontinence products to new mothers, including disposable and reusable solutions. It targets the same postpartum incontinence use case as Carin with a kit-based service model.

Broad incumbents

• TENA: TENA (Essity) is the global market leader in incontinence products, with disposable and reusable lines and deep retail distribution. It is a broad incumbent in the incontinence category that Carin's underwear product indirectly competes with.
• Knix: Knix offers leakproof underwear, bras, and postpartum apparel with a strong D2C and retail presence in North America. It competes with Carin's standalone underwear product and adjacent postpartum recovery apparel.
• Thinx: Thinx is a leading period and leak-proof underwear brand with broad retail distribution. It overlaps with Carin's standalone underwear product and represents a much larger incumbent brand in the adjacent reusable underwear category.

Direct peers

• INNOVO: INNOVO is a non-invasive, FDA-cleared pelvic floor trainer using external neuromuscular electrical stimulation. It is a direct peer competing for the same incontinence and postpartum customer with a non-invasive value proposition similar to Carin's.
• Perifit: Perifit offers app-connected pelvic floor training devices for women, including postpartum and incontinence programs. It competes head-to-head with Carin in the connected pelvic floor trainer category with a similar app-driven training model.
• Modibodi: Modibodi sells reusable period and light incontinence underwear with global D2C distribution. It is a direct peer in the leak-protective underwear category and a potential channel partner or competitor for Carin's standalone underwear line.
• Elvie: Elvie makes connected pelvic floor trainers (Elvie Trainer) and women's health hardware. It is the most direct competitor to Carin's connected pelvic floor category, with larger distribution and brand recognition, though using an insertable rather than underwear-based form factor.
