What DayTwo does
DayTwo is a precision nutrition company founded in 2015 that uses gut microbiome analysis combined with AI-driven glycemic response modeling to generate personalized dietary recommendations, primarily targeting health-conscious consumers and individuals managing blood sugar. Its core product is built on an AI platform that ingests microbiome composition, genetic markers, and metabolic response data to predict postprandial glycemic reactions to specific foods, replacing generic dietary guidelines with individualized nutrition plans augmented by virtual clinical support. The company is headquartered in Walnut Creek, California, operates as a private entity (DayTwo Ltd.), and employs 51-100 people, having raised approximately $90M across multiple funding rounds from 2016 through 2021 from investors including Johnson & Johnson, Mayo Clinic, aMoon Fund, Cathay Innovation, Samsung NEXT, Seventure Partners, and 10D.
The business model is consumer-facing with an implied subscription or test-and-program structure tied to microbiome profiling, though pricing is not publicly disclosed and no enterprise, payer, or employer channel details are available. DayTwo's strategic investor base (J&J for consumer health distribution, Mayo Clinic for clinical validation, Samsung NEXT for consumer data integration) signaled an attempted build-out across pharma, clinical, and consumer technology channels. Critically, several operational signals indicate material stress: the corporate website (daytwo.com) currently displays a parked GoDaddy landing page with no active product content, no funding round has been disclosed since the May 2021 Series B extension of approximately $37.4M, and no product launches, partnerships, or geographic expansions are visible in the available data. These signals collectively suggest that DayTwo's previously ambitious go-to-market may have contracted substantially since its 2021 capital raise, though no formal wind-down, restructuring, or acquisition announcement is disclosed in the source material.

DayTwo competitors and assessment
Company assessmentDirect peers
- ZOE: ZOE is the most directly comparable peer: a consumer subscription service combining gut microbiome testing, continuous glucose monitoring, and AI-driven personalized nutrition scores. DayTwo and ZOE pursue the same scientific thesis (microbiome + glycemic response) and the same D2C business model, making ZOE the primary head-to-head competitor.
- Viome Life Sciences: Viome offers gut microbiome and RNA-based testing with personalized nutrition recommendations and supplements, overlapping directly with DayTwo's microbiome + AI + nutrition value proposition for health-conscious consumers.
- InsideTracker: InsideTracker provides blood biomarker-based personalized nutrition and wellness recommendations, sharing DayTwo's data-driven, biology-based approach to dietary personalization and serving the same health-conscious consumer segment.
- Noom: Noom is a large-scale consumer weight-management and behavior-change platform. It addresses overlapping glycemic and weight-loss use cases with a coaching/coaching-app model, and is repeatedly cited in the same market research as DayTwo.
Broad incumbents
- Nestlé Health Science: Nestlé Health Science is a global nutrition incumbent with portfolio assets across medical nutrition, metabolic health, and personalized nutrition initiatives. It competes with DayTwo at the broad personalized-nutrition category level, especially for provider and consumer mindshare.
- Abbott: Abbott operates globally in diagnostics, medical nutrition (e.g., Glucerna), and metabolic health. It is a broad incumbent in the personalized/clinical nutrition space that could either compete with DayTwo or represent a strategic acquirer.
- Bayer Consumer Health: Bayer's consumer health division operates across supplements, nutrition, and digital health adjacencies and is listed alongside DayTwo in personalized nutrition market reports as a broad incumbent participant.
- dsm-firmenich: dsm-firmenich is a global nutrition, health, and ingredients company active in personalized nutrition partnerships and microbiome-related science, listed in the same market reports as a broad incumbent comparable to DayTwo.
Emerging players
- Levels: Levels sells continuous glucose monitors paired with a software platform for metabolic-health insights. It overlaps with DayTwo's glycemic-response use case and shares a health-conscious, data-driven consumer target.
- Habit (formerly): Habit (now part of Viome) was an early personalized nutrition service using biomarkers and biometrics to recommend individualized diets, sharing DayTwo's biology-first, consumer subscription model.
