Illustrative. Based on 200+ real Sphere TDD engagements. Individual findings vary by company size and complexity.
One Methodology. Six Practice Areas.
A single checklist can’t see six kinds of risk. Every engagement scopes to the decision you’re actually making.
Weeks, Not Quarters. Evidence, Not Opinions.
The same four-phase discipline powers every practice area — scoped to the decision, the industry, and the timeline in front of you.
Scope & Access
Define the decision at stake, agree the focus-area mix, and secure access to code, systems, and the people who run them. NDA within 48 hours.
Deep Assessment
Hands-on analysis across the agreed lenses — driven by evidence and direct code review, not interviews alone.
Quantify & Validate
Findings are costed, risk-ranked, and pressure-tested with the target or internal team before they’re reported.
Report & Roadmap
A defensible findings report plus a sequenced remediation roadmap — including a 100-day post-close plan when a deal closes.
Trusted By
21 years as an enterprise AI, data, and digital engineering consultancy — the same engineers who build and rescue production systems review the ones you’re about to buy.
