Company profile

researched Aug 2026

Shape (ShapeScale) is a health technology company based in San Francisco, California, that develops ShapeScale, a personal 3D body scanner combined with a scale and fitness tracker. The device scans a user in photorealistic 3D and produces a visual overview of body change over time, letting users compare two dates and view localized gains and losses via heatmaps, along with health and body scores intended to indicate which areas to target and whether training and diet efforts are producing results.

The product pairs with a companion ShapeScale mobile app, and the company's site also offers an augmented-reality preview of the device and orders through its website. The company positions the product around visual progress tracking rather than a single weight number, on the premise that gradual changes in fat and muscle are difficult to perceive in a mirror or capture on a conventional scale.

Founding story

The company was founded in 2015 and took part in Y Combinator's Summer 2015 batch. It is led by co-founders Alexandre Wayenberg (Founder/CEO) and Martin Kessler (Founder/COO), and describes its leadership as experienced hardware serial entrepreneurs.

Full profile — market position, technology, go-to-market, geography, history

Market position

Positioned as a consumer alternative to conventional bathroom scales and wearable fitness trackers, which report weight or activity numbers but do not show where fat has been lost or muscle gained. Coverage in outlets including TechCrunch, Engadget, CNET, Digital Trends, Men's Fitness, TechHive, Lifehacker and the Daily Mail has focused on the level of detail achievable in a home 3D scanning device.

The product's stated differentiator is photorealistic 3D visual output rather than numeric readouts: side-by-side before/after comparisons and heatmaps of localized body change, delivered from a home device rather than a clinical or gym-based scanner.

Technology

ShapeScale uses infrared depth sensors and a high-resolution camera to capture a photorealistic 3D representation of the user's body. The captured data is used to generate a 360-degree avatar, body measurements and body composition estimates, heatmap visualizations of localized gain and loss between two selected dates, and health and body scores. The company categorizes its work under hardware and computer vision.

Go-to-market

Online direct sales via shapescale.com supported by consumer technology and fitness press coverage, plus testimonials from personal trainers and prospective buyers featured on the company's site.

Fitness-focused consumers tracking body composition at home, along with personal trainers and their clients.
