What you get
What You Get in 4 Weeks
A technical due diligence report written for your deal team — valuation, integration, security, and scalability in one narrative.
Technical Risk Report
Clear findings by severity, business impact, remediation effort, and cost.
Dollar-Based Remediation Estimate
Technical debt translated into engineering hours, timelines, and budget impact.
Architecture and Scalability Assessment
A view of whether the target's systems can support the growth plan.
Security and Compliance Findings
Material gaps ranked by severity and remediation priority.
AI and Data Systems Review
Assessment of AI/ML components, data pipelines, governance, and defensibility.
100-Day Post-Close Plan
Practical execution plan for integration, modernization, remediation, and team scaling.
Scope of assessment
Every area that affects deal value or post-close risk
Code Quality & Technical Debt
Review of code structure, maintainability, test coverage, documentation, dependencies, and development standards.
Outputs

Severity-ranked remediation roadmap
AI, ML & Data Systems
Review of AI/ML components, model quality, data governance, pipelines, monitoring, and third-party model dependency.
Outputs
- Defensibility view
- Data lineage risks
- Vendor / model exposure
Asset vs. liability view with evidence
Team, Process & Product Maturity
Assessment of engineering structure, release process, key-person dependency, documentation, roadmap readiness, and delivery capacity.
Outputs

- Key-person risk
- 100-day readiness
Execution capability view for the deal thesis
Who this is for
Built for two deal scenarios
Understand whether the technology supports the investment thesis
Sphere helps investors answer:
- →Can the product scale with the growth plan?
- →How much technical debt will need to be funded?
- →Is the AI/ML capability defensible or commodity?
- →Can the engineering team execute after close?
- →What should be included in the 100-day plan?
Understand integration cost before the deal closes
Sphere helps acquirers answer:
- →Will the target's stack fit our infrastructure?
- →What will integration cost in engineering hours and timeline?
- →Which security or compliance gaps must be closed first?
- →What technical debt will our team inherit?
- →Can the target operate within our governance standards?

TDD checklist

How it works
How the TDD engagement runs
Scope the deal
We confirm the investment thesis, target profile, key risk areas, access needs, timeline, and deliverable format. NDA is signed before any materials are shared.
Review the full technical picture
Sphere reviews code, architecture, infrastructure, security, AI/data systems, team structure, and delivery process. The assessment is scoped to the deal, not run from a generic checklist.
Quantify the findings
Each material issue is translated into business impact, engineering effort, remediation timeline, and estimated cost. No vague red-yellow-green report.
Deliver the report
Your team receives a clear TDD report written for deal decision-making — it supports IC discussions, valuation, negotiation, integration planning, and post-close execution.
Support post-close execution
Sphere can support remediation, modernization, integration, infrastructure work, and team scaling after close — the team that identified the risks can help fix them.

With Sphere, we were able to migrate in half the time it would take to train an additional FTE — and for a fraction of the cost. Our experience with Sphere has been exceptional.
