Break nothing

Testing, security, compliance, and AI agent reliability — across the full surface of your software. Engaged as your partner, not a vendor.

We test what matters.

Software Quality

Functional testing, regression coverage, performance validation, and UI/UX review. We find what automated pipelines miss and what users find the hard way.

What gets tested

User flowsRegressionPerformanceAccessibilityEdge casesUI/UX

From functional coverage to accessibility — we test the full surface.

AI Agent Testing

Agents fail silently and confidently. We build eval harnesses, test output boundaries, and validate that agents behave the way your business requires — every time.

Hallucination caught before it reaches users
Output boundaries enforced and tested
Escalation triggers verified under pressure

Compliance & Security

HIPAA, SOC 2, GDPR, ISO 27001. Security vulnerabilities, access control gaps, and credential exposure — found before regulators or attackers do.

How We Work

A structured engagement, not an open retainer.

Every engagement starts with understanding your specific situation. The scope follows from that.

01

Discovery Call

We spend 20 minutes understanding your stack, your team, and where your quality gaps are most likely to be. No commitment required.

20 minutes
02

Scoped Proposal

Within 24 hours we send a specific proposal: what we'll test, how long it takes, and what you'll receive. Fixed scope. No surprises.

24 hours
03

Engagement

We embed into your process, do the work, own the findings. We stay until you can act on every one of them.

Scope-dependent

Ongoing relationships are available for teams who want continuous quality coverage. We'll discuss that after the first engagement.

The Fit

Built for teams that take quality seriously.

Startups & Scale-ups

You're shipping fast with a small team. Quality has been a 'we'll fix it later' item. Later is now. You have real users, real data, and real consequences. We help you build the quality layer your team never had time to build.

  • Seed to Series B
  • Engineering team of 2–30
  • AI-assisted or fast-moving codebase

Engineering Teams

Your team is strong but QA is either understaffed or non-existent. You need a quality partner who embeds into your workflow, not a vendor who drops a report and disappears.

  • 10–200 engineers
  • Continuous deployment cadence
  • AI tools in daily workflow

Regulated Industries

Healthcare, legal, and financial services teams work in environments where quality failures have regulatory consequences. We validate software and AI systems against the actual frameworks your environment requires.

  • Healthcare · Legal · Financial Services
  • HIPAA, SOC 2, GDPR obligations
  • AI systems in regulated workflows

We're probably not the right fit for teams building internal tools with no external users, chatbots, or low-stakes automation.

Case Studies

Work we've done.

Details are anonymized in line with client NDAs. The problems and outcomes are real.

Legal Technology

Autonomous contract review agent deployed with verified output controls.

A legal technology company needed to automate contract risk extraction at scale. The agent had to stay grounded in source material and escalate uncertainty instead of guessing.

What we did:

  • Built an evaluation harness against source documents
  • Implemented confidence scoring and human review thresholds
  • Verified citation accuracy before deployment

Deployed to production with no hallucination incidents in the monitored workflow.

Digital Health

Claims verification workflow automated with HIPAA-safe controls.

A digital health platform was manually verifying insurance claims across multiple payer formats. The process was slow, error-prone, and difficult to scale.

What we did:

  • Designed PHI-safe preprocessing before any model step
  • Built deterministic validation against payer-specific rules
  • Implemented immutable audit logging for every claim decision

Full intake workflow automated with compliance controls and auditability in place.

SaaS

Pre-launch quality review uncovered critical issues before users did.

A software team was two weeks from launching its first paid product. The codebase had been built quickly with AI assistance. They wanted confidence before onboarding customers.

What we did:

  • Full security and access control review
  • Business logic and edge case testing
  • UI/UX and accessibility validation

Critical issues were resolved before launch and the product shipped with a stronger production baseline.

The tools that help teams build faster do not verify what they ship.

AI generates code. It does not validate it.

Every AI coding tool optimizes for output speed. None of them verifies software against your actual business requirements.

Your test suite covers what someone remembered to test.

Automated tests only protect the scenarios that were written down. The biggest gaps live in what nobody thought to check.

Compliance has no sympathy for fast-moving teams.

HIPAA, SOC 2, and GDPR do not have a ‘we were moving quickly’ exception. Quality gaps become operational or regulatory problems.

Quality engineering used to be something only large teams built internally. Shellexa makes it available on demand, without the overhead of building the function from scratch.

The Team

A focused team. Enterprise-grade delivery.

We are a specialist quality engineering firm. Small by design, rigorous by practice. We work with funded startups, scaling engineering teams, and enterprise clients across the US, UK, and EU — and we bring the same structured process to every engagement.

Quality is not a final check. It's how reliable software gets shipped.

If you're shipping software or AI systems and quality is still something you're figuring out as you go, let's have a conversation. No commitment required.

We respond within 24 hours. Direct conversation with the people who'll do the work.
