Lambs

Lambs, recently rebranded as HAVN, operates within the health and wellness apparel market, targeting health-conscious consumers with a direct-to-consumer business model. The company was founded in July 2018 by Arthur Menard Calenge and Thomas Calichiama. Calenge, the CEO, is a serial entrepreneur with a background in engineering, biology, and business, who previously founded an online exam prep platform and a SaaS company for small businesses. His interest in the impact of environmental stressors on the human body, specifically wireless radiation, led to the creation of Lambs. The company initially launched under the name Spartan with a small equity crowdfunding campaign and a Kickstarter for men's underwear.

The core of Lambs' product line is its proprietary WaveStopper™ fabric technology, which is inspired by NASA spacesuit technology. This fabric incorporates a mesh of silver-lined wire woven into materials like cotton, which is designed to block 99% of electromagnetic field (EMF) radiation from sources such as Wi-Fi, Bluetooth, and cellular signals. The efficacy of this technology is certified by military-grade laboratories according to IEEE-299 standards. The silver fibers also provide antimicrobial, anti-odor, thermoregulating, and hypoallergenic properties. In addition to EMF protection, the apparel offers a UPF 50 rating, blocking 99% of UV rays.

Lambs generates revenue through the online sale of its products, which include t-shirts, hoodies, underwear, beanies, and caps for men and women. The company positions itself as a health-enhancing apparel brand, aiming to improve customers' sleep, recovery, and cognitive function by reducing exposure to external environmental stressors. Having achieved profitability and significant growth, Lambs has attracted investors like Science Ventures and Brett Conrad, the former president of Lululemon. In early 2025, the company announced its rebranding to HAVN to better reflect its mission of providing a safe haven from modern health threats like EMF radiation.
