Identify trust gaps
before they cost you revenue.

Subsurface surfaces hidden friction across product, payments, and user experience before it impacts growth.

What we do

We find where products quietly lose trust.

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.

What's quietly costing you users, revenue or trust?

Most issues don't break your product. They show up as:

  • users dropping off without explanation
  • confusion in key flows
  • payment or state inconsistencies
  • trust signals that don't hold up

If something feels "off" but you can't pinpoint it, this is where Subsurface works.

What we surface

Hidden conversion friction

Silent failures in checkout flows, authentication loops, and payment processing that users abandon without reporting.

Misaligned trust signals

Inconsistent messaging, unclear error states, and validation gaps that erode user confidence.

Risk patterns across user journeys

Recurring issues in multi-step flows where trust breaks down at predictable points.

Gaps between claims and experience

Where product promises don't match actual behavior, creating credibility loss.

Free diagnostic

Start with the Trust Signal Scan

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.

DIAGNOSTIC FRAMEWORK

Four Failure Domains We Analyse

Evidence Integrity

Are system decisions explainable? Are failures visible or hidden from users and operators?

Identity Credibility

Can users bypass or manipulate flows? Are validations consistently enforced across all entry points?

Operational Visibility

Are errors logged and surfaced? Can you detect delays, inconsistencies, and anomalies in real-time?

Control Architecture

Are safeguards properly layered? Are edge cases handled and critical flows protected from failures?

Our methodology

QA Radar. The judgment layer.

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.

Read the methodology (PDF)
01
Evidence capture
Every finding is tied to a reproducible trace, screenshot or log line, never opinion.
02
Severity weighting
Scored on user trust damage, commercial impact and how reversible the failure is.
03
Pattern clustering
Isolated bugs are grouped into trust-failure patterns so you fix the cause, not the symptom.
04
Judgment call
A ranked shortlist of what to fix this week, this month, and what to safely deprioritise.

The book

Signal, Not Siren.

A working field guide on why modern products quietly lose user trust, and how to surface it before it costs revenue.

Written from inside real engagements. No frameworks for their own sake. Just the failure patterns we see repeatedly, the ones that never appear in a bug tracker, and the structural questions that predict them.
