Responsibilities
  • Build AI systems that connect legacy data sources, including ERP systems, sensors, spreadsheets, and custom tools, into a unified, real-time view of factory operations.
  • Run real-time simulations over global factory state to balance work order demand and load, mitigate delay propagation, identify operational bottlenecks, and justify scheduling priorities by quantifying downstream profit impact.

  • Design just-in-time generative interfaces that make production legible and deliver clear recommendations.

About the company

Complement helps people on plant-based diets by selling a single multivitamin designed for vegans and vegetarians through its website. The capsule combines essential vitamins and minerals that might be missing from a plant-based diet, so customers don’t need multiple bottles. It works by taking one daily capsule to cover nutrient needs, and peppermint is added to improve taste and scent. The product is sold direct-to-consumer, with affordable pricing and the convenience of a single supplement. Complement differentiates itself by focusing on the vegan/vegetarian niche and packaging multiple nutrients into one capsule, aiming to simplify supplementation and reduce cost. The goal is to support energy, mood, sleep, and overall wellbeing for people following plant-based diets by making nutrition easier and more affordable.

Simplify's Take

What believers are saying

  • Complement Essential updated March 8, 2026, showing active product iteration.
  • The site still markets 48% more omega-3s than leading multivitamins, supporting differentiation.
  • A 2026 bundle and trial pricing suggest aggressive customer acquisition and retention focus.

What critics are saying

  • California Prop 65 notices in 2026 name Outlier Health dba Complement as violator.
  • A $5.445 million financing signals cash need, not durable self-funding.
  • If supplement efficacy or labeling claims unravel, Complement loses trust and DTC sales fast.

What makes Complement unique

  • Complement Essential packs B12, D3, K2, iodine, magnesium, zinc, selenium, DHA/EPA.
  • It uses lichen-sourced Vitashine D3 and algae-derived omega-3s, both fully vegan.
  • ForHer, launched 2024, targets plant-based women with six added nutrients.
