POSITIONING STATEMENT

The Verification Layer Above Your CDS.

WLTR is a deterministic calibration validation platform that sits above your existing CDS — Agilent OpenLab, Thermo Chromeleon, Waters Empower, Shimadzu LabSolutions, Sciex MassHunter — and re-evaluates calibration mathematics against your own data.
 
WLTR does not modify your state-validated methods. WLTR does not change action limits. WLTR does not generate the Certificate of Analysis. The CDS remains your system of record. WLTR verifies what the CDS produces, identifies calibration models that pass on the surface but contain undetected error, and documents the verification in language a state inspector reads.
 
For cannabis testing laboratories operating under California DCC, Colorado MED, Michigan CRA, Florida OMMU, New York OCM, Massachusetts CCC, Illinois IDOA, New Jersey CRC, Arizona ADHS, Washington WSLCB, Nevada CCB, or Health Canada licensure, WLTR is the independent calibration intelligence layer the CDS was never designed to be.

THE REGULATORY REALITY

Calibration Is Now an Enforcement Category.

State cannabis regulators are no longer accepting a passing Certificate of Analysis on its face. Inspectors re-evaluate the calibration mathematics behind the result. Where the math fails, the laboratory fails — regardless of whether the COA itself reported a pass.


The vocabulary of recent enforcement is narrow and consistent: data integrity, method validation deficiency, inaccurate or unreliable results, scientific integrity, competence demonstration. WLTR is built to occupy that documentary terrain.

Enforcement Evidence

Five Recent Actions.
Five Different States.
One Pattern.

The labs below were not outliers. Each operated a state-licensed compliance scope, each issued passing COAs, and each was found by a state regulator to have produced results that could not survive independent verification.

CALIFORNIA — DEPARTMENT OF CANNABIS CONTROL

Sequoia Analytical Labs surrendered its testing license in November 2018 after a state inspection determined that 22 of 66 California-required pesticides were not being correctly tested due to a faulty instrument. Approximately 700 to 850 batches of falsified COAs triggered the largest cannabis recall in California history at the time.

MICHIGAN — CANNABIS REGULATORY AGENCY

Viridis Laboratories had its license revoked by consent order on August 19, 2024, with three majority owners permanently banned from the Michigan cannabis industry. The CRA cited a “sustained, deliberate pattern of noncompliance,” following a 2021 recall of approximately $229 million in tested product for “inaccurate and/or unreliable results.”

NEVADA — CANNABIS COMPLIANCE BOARD

A Las Vegas testing facility was the subject of a 44-page complaint filed in January 2021 detailing 22 violations, including practices “designed to inflate THC potency” and 232 instances of unauthorized retesting. Outcome: $57,500 fine and 180-day license suspension.

CALIFORNIA — DEPARTMENT OF CANNABIS CONTROL

Verity Analytics was suspended in April 2024 after twelve violations including allegations of inflating THC potency by up to 32%. The DCC reported a 50% increase in disciplinary actions against testing laboratories in 2024 over 2023.

NEW YORK — OFFICE OF CANNABIS MANAGEMENT

Lexachrom Analytical Laboratory surrendered its OCM permit in May 2025 after a stop-work order. Products certified by the lab were subsequently determined by a second permitted laboratory to “contain unallowable levels of pesticides,” triggering OCM recalls in June and July 2025.

How WLTR Fits

Above the CDS. Below the LIMS. Independent of Both.

WLTR ingests calibration data from the CDS, applies deterministic mathematical validation, and returns a verification record to the laboratory. The CDS remains the system of record. The state-validated method is unchanged. No regulatory re-approval is required to deploy.

What WLTR Does

Three Things WLTR Does. Nothing It Should Not.

WLTR is built to a strict regulatory boundary. It verifies, evaluates, and documents. It does not modify, replace, or augment any compliance-critical calculation.

01

Validates
WLTR re-evaluates calibration mathematics against the laboratory’s own raw data. Calibration models that pass acceptance criteria on the surface but contain undetected error are identified at the source — before the result is released to METRC, the customer, or the state.

02

Verifies

WLTR operates above any CDS. The same verification logic runs against an Agilent OpenLab dataset, a Thermo Chromeleon dataset, a Waters Empower dataset, or a Shimadzu LabSolutions dataset. Multi-state operators running mixed CDS estates do not need a separate validation workflow per platform.

03

Documents

Every WLTR verification produces a fully traceable, audit-defensible record in the language state regulators use. Data integrity. Method validation. Quality control demonstration. Ready for inspection on day one.

Who It Is For

Built for the People Who Live with the Consequence.

01

THE LAB DIRECTOR
Operating eight to fifteen chromatography instruments across a mixed CDS fleet. Cannot afford to revalidate state-approved methods. Needs a verification layer that works above what is already deployed.

02

THE QA OFFICER

Owns the document trail the state inspector reads. Defends data integrity at unannounced inspections. Trains analysts against state-by-state SOP divergence. Needs verification output in regulator-aligned language.

03

THE ANALYTICAL CHEMIST
Builds calibration curves under 24- to 72-hour turnaround pressure across potency, pesticides, residual solvents, heavy metals, mycotoxins, microbials, terpenes, water activity. Works through single-analyte CDS workflows on terpene-rich, edible, and vape-oil matrices. Needs the calibration math reviewed before the COA goes out.

04

OWNERSHIP AND CORPORATE LEADERSHIP

Carries the existential risk. State license suspension has no federal recourse, no portable accreditation, no insurance path. Civil litigation exposure has expanded — Trulieve, MCR Labs, Central Coast Agriculture. Needs an independent record that calibration was verified, every batch.

WLTR is a quality-system verification layer.

WLTR is not a method modification.

The CDS remains the system of record for all reportable results. The state-validated method is unchanged. No regulatory re-approval is required to deploy. The COA is generated by the laboratory, not by WLTR.

Verify the calibration. Defend the data.
