Filament Sciences was launched and bootstrapped by founder Nathan Puksta, a L'Oréal veteran, and positions itself as a professional, science-led hair care brand emphasizing scalp health. The company proved product-market fit and early distribution traction before raising external capital. It has just closed a $2 million seed round to support scaling inventory and expanding into the salon professional channel. Filament also plans to invest in education as part of its growth strategy for professionals. The financing marks the company’s shift from founder-funded to partner-backed growth while keeping a tightly controlled cap table.
