Identify trust gaps before they cost you revenue. Subsurface surfaces hidden friction across product, payments and user experience before it impacts growth.
Subsurface is a Trust and Risk Architecture consultancy for founders, product teams and operators building digital products where credibility is the product. We don't run generic audits. We investigate specific flows, such as onboarding, checkout, identity, payments and state handling, and show you exactly where users stop believing, stop paying or stop returning. Every engagement begins with evidence. Every recommendation is traceable to a real failure pattern, not a framework opinion.
Most issues don't break your product. They show up as users dropping off without explanation, confusion in key flows, payment or state inconsistencies, and trust signals that don't hold up. If something feels "off" but you can't pinpoint it, this is where Subsurface works.
A structured 12 question diagnostic across four failure domains, covering Evidence Integrity, Identity Credibility, Operational Visibility and Control Architecture. You receive an AI-generated trust report with a domain-level score, the highest-risk signals in your product, and a shortlist of the flows most likely to be quietly costing you revenue. No call required.

Automation catches failures. Judgment catches the ones that matter. QA Radar is our internal method for turning raw signals into prioritised, explainable risk. We weight every finding by commercial impact, reversibility and user trust damage, so you get a short list of what to fix, not a dump of what's broken.
