Scoring rationale
WATCH — Sourmilk is a pre-seed NYC probiotic Greek yogurt brand founded in 2025 by Elan Halpern and Kiki Couchman (Stanford roots), currently running a novel bike-delivery D2C model in Manhattan with retail launch slated for fall 2025 (Dairy Reporter, Sept 25 2025). Public traction is nascent: Instagram at 130 followers, TikTok at 6 followers, zero live Foreplay ads, no Amazon presence (the SOURMILK ASINs are unrelated canvas art), and no disclosed funding on LinkedIn. The concept — two-ingredient, clinically-dosed probiotic yogurt as 'supplement in food form' — is on-trend with gut-health tailwinds, but at this stage it is a concept bet on founders, not a traction bet.
Traction: 0 press · 0 ads · BSR Δ35% · TikTok 6 → 2/25
Authenticity: IG 130 · TT 6 · -4 Amazon reviews · 0 subreddits → 3/20
Capital: 0 funding press (penalty 0) · TM sweet-spot no · 0 ads → 11/15 (higher = pre-raise)
Category timing: food (probiotic greek yogurt) trend flat · brand trend flat → 4/12
