Pre-seed — Q1 2026

The payability layer for contingent payments

Celium converts delivery evidence into deterministic, finance-grade Payment Eligibility artefacts — the missing infrastructure between project delivery and payment systems in nature, construction, government, and IT.

The Problem
Across four verticals, payment depends on proving performance — but the infrastructure to do that reliably doesn’t exist. Non-fundamental risk, not ecological uncertainty.

Section 2
The Solution
A cashflow standardisation engine. EP → VD → PE artefact chain converts delivery evidence into deterministic, finance-grade payment eligibility.
