Technical Due Diligence & Vendor Sourcing
An independent engineer’s view before you invest, acquire, or sign with a software vendor.
Boards, investors and non-technical leaders often have to make large technical decisions on the strength of a vendor’s own slides. DeltaBreen gives you an impartial, practitioner-level assessment: of a company’s codebase and infrastructure before a deal, or of the suppliers bidding for your project before you commit.
Technical due diligence
For investment rounds, acquisitions and major contracts.
- Code and architecture review: Quality, test coverage, maintainability, and how much of the product is real versus prototype.
- Infrastructure and security: How the system is hosted, deployed and secured, and what an incident would look like.
- Team and process: Key-person dependencies, delivery cadence, and whether the roadmap is credible with the people in place.
- Plain-language report: Findings ranked by risk with the cost to fix, written for the people making the decision.
Vendor sourcing and bid review
For organisations choosing an agency, contractor or platform.
- Requirements and RFP: Turn what you need into a specification that vendors can price honestly and you can hold them to.
- Proposal scoring: Compare bids on substance: architecture, team seniority, testing, hosting, exit terms, and the assumptions hidden in the timeline.
- Contract review: Deliverable definitions, acceptance criteria, source-code ownership and lock-in clauses checked by an engineer, alongside your legal advisers.
- Delivery oversight: Optional ongoing review of what the chosen vendor ships against what was promised.
How it works
- Scope
Agree what decision the work supports, what access we will have, and the deadline. Fixed price from here.
- Assess
Read the code, inspect the infrastructure, interview the team or vendors. We look at what exists, not what the deck says.
- Report
A written report and a call to walk through it. You can put our findings in front of the other side.
Common questions
- Are you independent?
- Yes. We take no referral fees or partnerships from vendors or platforms, and we do not bid for the work we assess.
- How long does technical due diligence take?
- Typically one to three weeks depending on the size of the codebase and how quickly access is arranged.
- Can you work under NDA?
- Yes. Confidentiality is standard for this work.
