Technical Due Diligence / Deal Advisory

Know What You're Buying Before You Sign.

Most technical surprises surface in the first 90 days after close — not during diligence. We find them before the term sheet, so the price reflects what you're actually acquiring.

You're in the right place if —

01

You're evaluating a software-enabled acquisition and need a technical read before the term sheet.

02

Your fund doesn't have a technical partner on staff — and hiring one full-time doesn't make sense for deal volume.

03

The target's engineering team says everything is fine. You'd like a second opinion.

04

You've been burned before by a codebase that looked clean and wasn't.

05

You need a risk memo your partners can act on — not a slide deck full of jargon.

06

You want a technical advisor on call before the next deal shows up, not after.

Scope of Engagement

What the Assessment Actually Covers

Not a checklist. Not a slide deck. A working assessment with a decision your deal team can act on.

Architecture & Codebase Health Assessment

A plain assessment of what's actually built versus what's claimed — architecture, dependencies, scalability limits, and what breaks under real growth.

Technical Debt Quantification

A concrete estimate of what it will cost, in time and dollars, to fix what's broken or outdated — not a vague 'needs work' verdict.

Team & Process Evaluation

Whether the team and processes in place can sustain the business post-close, and whether key-person risk is real.

Security & Data Posture Check

A pass on access control, data handling, and the obvious liabilities that turn into post-close surprises.

Plain-English Risk Memo

Buy, pass, or price-adjust — with the reasoning shown, written for partners, not engineers.

Post-Close Roadmap (Optional)

A prioritized first-100-days technical plan — what to stabilize first, what to defer, so the deal team isn't guessing after close.

Technical Provenance

Why All Stone Tech

Most diligence advisors have either enterprise depth or startup speed. Rarely both — and rarely at deal-timeline pace.

Forty Years, Every Era

Hands-on experience from mainframe and legacy systems through modern cloud-native and AI-integrated architectures — a rare ability to accurately assess both the target's current stack and whatever it's running underneath.

Fortune 20 Depth

Directed architecture for a Fortune 20 multi-application platform managing multi-billion-dollar budgets. We know what a system built to survive scale actually looks like.

MVP Rescue Track Record

We've audited failing architectures and shipped stabilized, production-ready systems in weeks, not months — across fintech, legal tech, and healthtech.

Diagnosis First

We don't take a target's self-assessment at face value. We look at the actual code, the actual infrastructure, and the actual team before we render a verdict.

Deal-Speed Turnaround

Rapid assessments are built for diligence timelines — days, not weeks — so a technical read never becomes the bottleneck on a deal.

Engagement Structure

How Engagements Are Structured

Built for diligence timelines. Every engagement starts with a fixed scope and a clear delivery date — no open-ended discovery.

Post-Close

100-Day Technical Roadmap

For deals that have already closed. A prioritized technical plan for the first 100 days — what to stabilize first, what to defer, and what the team should be doing instead of guessing.

Operating Protocol

"A codebase you haven't read is a price you haven't verified."

We don't take the target's self-report at face value. We read the code, check the infrastructure, and talk to the team before we render a verdict — the same diagnosis-first discipline behind every AST engagement, compressed to deal timelines.

A 15-minute call is enough to know whether a Rapid Assessment fits your timeline. If it doesn't, you'll know that too.
