Building the Intelligence Layer
for Sustainable Commerce
JustKalm is building AI infrastructure for the circular economy — helping brands, marketplaces, and consumers make informed decisions about product value, sustainability, and safety.
JustKalm is pre-launch. We publish targets and methodology rather than traction metrics we cannot yet substantiate.
Market Opportunity
Positioned at the intersection of three rapidly growing markets.
Third-party market estimate. Not a JustKalm measurement.

Competitive Moat
Defensible advantages that compound over time.
Transparent validation
We publish our validation harness, our calibration error and our known limitations — including where the model is weakest.
Three-pillar intelligence
A single endpoint returning valuation, sustainability and health signals rather than three fragmented lookups.
Infrastructure built to a standard
Built with SOC 2-aligned controls, with a <200ms API response target. Targets, not measured service levels — see /methodology.
Compounding data advantage
Each valuation is designed to improve subsequent predictions. This is an architectural property, not yet a demonstrated result.
Company Milestones

Roadmap targets
Public API launch
Ship the public API with initial design-partner integrations.
First design partners
Onboard an initial cohort of brand and marketplace design partners. We will publish partner counts once they are contractually confirmed.
Health intelligence capability
Extend scoring with toxicology screening and health assessment.
Third-party model audit
Independent review of the valuation methodology. Scheduled, not complete.
International expansion
Extend coverage beyond the US/EU launch markets.
