SuppCo

What SuppCo does

SuppCo (legally SuppleStack, Inc.) is a New York-based consumer health platform founded in October 2024 by Steve Martocci (CEO, previously co-founder of GroupMe, Splice, and Blade) and Nick Michlewicz. The company operates a mobile app (iOS/Android) and companion website that helps individual consumers navigate the fragmented dietary supplement market through three primary product modules: TrustScore, a proprietary quality rating system that scores 35,000+ products across 8,000+ brands on 29-39 attributes (cGMP compliance, ISO 17025 testing, certifications, ingredient transparency); StackScore, a personalized stack-analysis algorithm that scores a user's combined supplement regimen for goal coverage, dosing, and quality; and SuppIQ, an AI-powered supplement assistant chatbot built on third-party LLMs from Anthropic and OpenAI. The platform is augmented by a Nutrient Research Center (20,000+ scientific papers), 80+ Expert Protocols authored by named functional-medicine physicians, community features (Lists, posts, comments), and the TESTED by SuppCo independent ISO 17025-accredited certification program that anonymously purchases and verifies supplement label claims.

The company employs a freemium, product-led growth model: the core app is free, with a paid SuppCo Pro subscription tier offering advanced personalization (custom nutrient plans, Lab Results Upload, smart scheduling, unlimited SuppIQ access). Additional revenue is generated through Amazon and brand affiliate commissions on outbound purchase links and through B2B certification fees paid by supplement brands participating in the TESTED program. SuppCo raised $5.5M in seed funding in October 2024 (co-led by Union Square Ventures and True Ventures with Box Group and Compound) and grew its user community from approximately 60,000 in March 2025 to over 500,000 by the end of 2025. On May 12, 2026, SuppCo was acquired by Function Health (valued at $2.5B following its $298M Series B), with the entire SuppCo team joining Function to integrate biological lab monitoring (160+ markers) with supplement tracking and personalized protocols.

Core offering

SuppCo operates a consumer-facing mobile and web application (iOS/Android) that helps individuals find, evaluate, and track health supplements. The platform indexes 160,000+ products across 8,000+ brands, assigns each product a proprietary TrustScore quality rating, and uses its StackScore algorithm to analyze users' combined supplement regimens. The free app supports routine adherence via reminders and barcode scanning, while SuppCo Pro adds personalization features and the TESTED by SuppCo program provides independent ISO 17025-accredited lab verification of supplement label claims for brands.

Product overview

SuppCo (operated by SuppleStack, Inc.) operates as a unified consumer health platform — a single mobile/web application (the SuppCo App) extended by several tightly integrated modules: TrustScore for product quality ratings across 160,000+ supplements, StackScore for personalized stack analysis, the Nutrient Research Center for evidence-based content, SuppIQ as an AI-powered personal supplement assistant chatbot, and SuppCo Pro as the premium subscription tier offering advanced personalization. On top of this core platform, SuppCo layers content modules including Expert Protocols (curated plans from renowned functional medicine experts) and an independent certification program called TESTED by SuppCo (ISO 17025 lab verification). Tracking features — Nutrient Journeys, Peptide Tracking, Lab Results Upload, and Biomarker Analysis — complement the core stack. A SuppCo Community layer (posts, comments, lists) ties the offering together as the company's "Supplement Collective." SuppCo was acquired by Function Health in May 2026, with all StackScore, TrustScores, and Community features continuing to operate under Function, integrating biological lab data with supplement tracking.
