Monthly

What Monthly does

Monthly is a direct-to-consumer period underwear brand headquartered in Alabama, founded by Aiko Pickering in 2021-2022 after she was diagnosed with pelvic floor dysfunction and could not use traditional tampons or cups without pain. The company designs and sells gender-inclusive boxer-style period underwear targeted at people with complex periods, including those with PCOS, endometriosis, adenomyosis, fibroids, pelvic floor dysfunction, and gender dysphoria. Monthly's flagship product, The Boxer Brief, features a proprietary 4-layer gusset with a cotton top layer, two bamboo-blend absorbent middle layers, and a TPU leak-proof backing, holding approximately 25ml of flow. The product is PFAS-free (third-party tested by Bureau Veritas) and uses GRS-certified recycled nylon, GOTS-certified organic cotton, and OEKO-TEX 100 certified fabrics. Manufacturing is outsourced to a partner facility in Guangdong, China holding BSCI, GOTS, OEKO-TEX 100, and GRS certifications.

The company operates as a Public Benefit Corporation and generates revenue exclusively through its Shopify-powered e-commerce storefront (shopmonthly.co). Pricing ranges from $25 per pair for individual Boxer Briefs to $148.75 for a 7-pair bundle, with 5-15% bundle discounts on 3/5/7-pair packages. Monthly accepts HSA/FSA payments through a partnership with Flex and ships worldwide with free standard shipping on qualifying US/Canada orders. A new heavy-flow variant, The Boxer Brief Heavy ($28/pair), opened for pre-order in September 2025 with delivery scheduled for September/October 2025. The company has raised a single disclosed funding round of $100,000 (April 2023) from gener8tor Oklahoma City Investment Accelerator and Right Side Capital Management, and has received brand validation through a British Vogue wellness feature (March 2025) and selection as a CoCreate Pitch Competition finalist (September 2025) out of 25,000 applicants. As of early 2025, the founder was the sole full-time employee, with friends and family assisting during peak periods, and operations had only recently expanded from a home-based guest bedroom to a garage workspace.
