What Labdoor does
Labdoor is a San Francisco-based independent testing company founded in 2012 that operates in the dietary supplement and protein powder quality verification market. Its core product is a third-party laboratory testing service that subjects protein powders, plant-based proteins, and related supplements to assays for protein content, label accuracy, purity, heavy metal contamination, and microbiological contaminants. Test results are aggregated into rank-ordered product recommendations that are published through Labdoor's own consumer-facing marketplace and through media partnerships, most notably Forbes Health's annual protein powder rankings.
The business serves a dual-sided audience. On the supply side, protein powder and supplement brands use Labdoor's certification to substantiate quality and safety claims and to differentiate in a category where consumer skepticism is high. On the demand side, health-conscious consumers use Labdoor's published rankings to compare products on a standardized, third-party-verified basis. The company's core technology is its proprietary testing methodology, which combines wet-lab analytical chemistry with a growing proprietary database of brand-level quality results that compounds with each product tested. Distribution is heavily dependent on earned media and publication partnerships rather than paid acquisition.
Labdoor has raised approximately $10.79M across five funding rounds between 2012 and 2016, with the last round ($3.4M Series A) led by Floodgate. The company is private, reports 11-50 employees, and has not disclosed revenue. The investor base includes Y Combinator, Rock Health, Correlation Ventures, Floodgate, 500 Global, and DeNA, among others. Leadership comprises CEO Rafael Ferreira, co-founder and CTO Helton Souza, and Chairman Neil Thanedar. As of 2025, the company's consumer website (Labdoor.com) was returning a default Apache test page, which, combined with the absence of funding since 2016, signals limited ongoing investment in the consumer-facing surface.
