Six areas, benchmarked to your stage. Every score is backed by detailed evidence and reviewed by an operator.
Architecture
System design, scalability, data model and infrastructure.
Security & compliance
Vulnerability surface, auth, data privacy and compliance posture.
Code & delivery
Test coverage, CI/CD cadence and tech debt, quantified.
Team & organisation
Key-person risk, engineering culture and hiring gaps.
AI readiness
Real IP versus wrapper, model governance, build versus buy.
Product & strategy
Product-market-fit signals, roadmap quality and commercial alignment.
Beyond the score
- Beyond the score
- Contributor and key-person mapping
- Test coverage across layers
- Delivery velocity over time
- Proprietary IP and non-trivial engineering
- Dependency and CVE exposure
Align your roadmap with your commercial strategy.
A quarter of the average engineering budget builds features that don’t move the business. We map where capacity goes and rebuild the link between what you ship and what it’s worth.
01
Roadmap audit
Map every current roadmap item against commercial goals. Identify what drives revenue and what doesn’t.
02
BON workshop
Map every current roadmap item against commercial goals. Identify what drives revenue and what doesn’t.
03
Stakeholder alignment
Bring product, engineering, sales, and leadership together around agreed priorities.
04
Prioritisation framework
Install a repeatable model balancing revenue impact, effort, and strategic fit.
05
Quarterly planning cadence
Tie quarterly roadmap reviews to commercial KPIs and board reporting.
06
Board-ready reporting
Connect roadmap progress to the metrics investors care about.
Around two to three months, end to end. Scoped to your team and stage.
Instead of hiring more developers, reduce your bottlenecks.
When velocity drops, the instinct is to hire. But adding people to a team with structural friction makes it worse. We find the friction that slows your team down and remove it, structurally.
Seven modules to remove friction and build speed:
Friction mapping
Identify the top bottlenecks: review cycles, deployment pain, unclear ownership, knowledge silos.
Cadence installation
Install the layered operating rhythm so every meeting drives a decision.
Team topology review
Evaluate team structure against product architecture. Fix misalignments that create handoff overhead.
Key-person mitigation
Reduce single points of failure. Spread critical knowledge through pairing, documentation, and rotation.
Velocity metrics
Install meaningful delivery metrics, not vanity numbers. Track throughput, cycle time, and quality over time.
AI opportunities
Identify where AI accelerates your team, from code generation to testing to documentation.
Hands-on coaching
Embed operators with team leads to build and sustain better habits.
Around two to three months, with operators embedded. Scoped to your team and stage.
Your code is treated like it is our own.
Read-only, encrypted, and gone when we’re done, with confirmation in writing at every step.
Your code stays only briefly
It lives in a secure, isolated dataroom for the engagement, encrypted and scoped to this engagement alone.
Read-only and revocable
A full system walkthrough rather than a document review.
Zero storage, confirmed
Nothing is kept or shared. When the dataroom is wiped, you receive written confirmation.
NDA by design
Confidential from the first minute. Our template or yours, signed the same day.

See how you run, and how you compare.
We have X-Rayed 300+ companies across 11+ verticals, so every area is measured against companies at your stage, in your space.
Built by founders and CTOs who’ve scaled companies before.
The people reading the code are operators: they have built and scaled software companies themselves, and review every finding before it reaches you.

What CTOs and founders say about the X-Ray
“I had never experienced a technical due diligence process that required so little time from our team while still producing such a useful assessment.”

“Scaleflow went deep on both our hardware supply chain and the software behind it. A thorough process, and the recommendations were practical, exactly what we needed going into the round.”

“From kick-off to report in two weeks, right when our round needed it. Professional, pragmatic and pleasant to work with.”

“A really helpful outside validation that the direction we’d chosen was the right one. It gave us the confidence to keep building along that path.”

FAQs about technical due diligence for startups
Three ways, from granting temporary access to keeping your code entirely in your own hands. Grant our reviewer read-only access for a short while, the same way you’d onboard an engineer, and revoke it the moment the scan starts. Install a scoped GitHub or GitLab app with read access to only the repositories you choose. Or upload it yourself to a single-use, encrypted bucket. Whichever route you choose, your code runs in a locked-down EU environment, is never executed or read line by line, and nothing is sent to the US.
