For research companies

Reach research buyers at the moment they’re comparing.

Put your company in front of Crimson Index visitors researching compounds, reviewing testing information, comparing providers, and evaluating research products. Two tiers, one flat monthly price each, and a label on every paid position.

Two tiers. That is the whole price list.

Monthly, no contract, cancel by email. Prices are per company, not per product.

Verified Provider

$99/month

A permanent, searchable listing in the directory for companies that want buyers to be able to find and evaluate them.

  • Provider profile page with logo, description and website link
  • Your catalogue with amounts, prices and price per unit
  • Testing and certificate-of-analysis information where you supply it
  • Included in provider comparison tables and on relevant compound pages
  • Self-service portal to keep everything current

Featured Provider

$249/month

Everything in Verified Provider, plus a clearly labelled priority position. Featured slots are limited so the label keeps meaning something.

  • Everything in Verified Provider
  • Priority position in the directory, labelled Featured placement (paid)
  • Enhanced profile: promotion note, shipping terms and highlighted catalogue
  • Labelled placement on relevant compound comparison sections
  • Advertiser analytics: listings shown, profile opens and outbound clicks

Featured positions are limited to 6 companies at a time. When they are full, new applicants join a waiting list at the Verified tier.

Who you are reaching

They arrive to read, not to browse ads

Visitors come for compound dossiers, published study summaries and guidance on what certificate-of-analysis testing actually proves.

They are comparing before they buy

The provider directory and the per-compound price tables are the last step of that reading, which is where your listing sits.

You get the numbers we can actually measure

Listings shown, profile opens and clicks through to your website, by day. We report what is recorded and nothing else.

We do not publish traffic estimates we cannot evidence. Ask us for current figures when you apply and we will send you what the platform has actually recorded.

What money can and cannot buy

  • Can buy: a listing, a profile page, a labelled priority position in the directory, and a labelled placement on relevant compound pages.
  • Cannot buy: the independently verified label, a better position in a price comparison, removal of a competitor, edits to any educational or evidence content, or any wording that suggests we endorse a product.

Verification is earned separately and free: send a certificate, we contact the laboratory named on it, and we mark only that document as confirmed. It never becomes a claim about safety or effectiveness. See what testing proves.

Advertising and sponsored listings pay for this platform. A company can buy visibility; it cannot buy a verification label, a better evidence summary, or a position in the assistant's answers. Nothing in this directory is medical advice, a scientific endorsement, or a guarantee about any product.

Tell us which tier you want. We reply with the listing checklist and an invoice; nothing goes live and nothing is charged until you confirm. Questions first? Email crimsonindexsupport@gmail.com.

Card payment is not yet connected, so applying and invoicing is currently how companies join.
