What it is
Independent technical due diligence for investors, funds and strategic acquirers: architecture, security, team, product, vendors.
For whom
VC, private equity, family offices and strategic acquirers needing to validate a target in 7 to 14 business days with no conflict of interest.
Indicative price
EUR 8,000 to 40,000 excl. VAT depending on scope. No success fee, strict neutrality, multi-party NDA.
Who this service is for
Venture Capital funds
Series A to C: validate the stack robustness before a meaningful cheque, without relying on the target CTO's self-assessment.
Private Equity & Growth Equity
LBO, build-up, take-private: measure technical debt, key-person dependency, capacity to absorb an ambitious roadmap.
Family Offices
Direct or co-investment: no internal tech arm to challenge an overly optimistic management report.
Strategic acquirers & M&A boutiques
Corporate acquisition, spin-off, carve-out: size the integration effort and the post-closing team-departure risk.
Report deliverables
Architecture & stack
Full technical architecture map, third-party dependencies, quantified technical debt, identified breaking points.
Security & compliance
Cybersecurity posture (ANSSI, ISO 27001, NIST CSF, GDPR), cyber hot spots, sector compliance where applicable (health, finance, construction).
Team & organisation
Key-person mapping, bus factor, technical culture, hiring capacity, dependency on founders and contractors.
Product & roadmap
Product-market-tech coherence, 12-24 month roadmap feasibility, product debt vs. technical debt, expected scale effects.
Vendors, contracts, licences
Critical vendor mapping (cloud, SaaS, subcontractors), software licences, contract obligations, reversibility.
Structured report + executive summary
40 to 80 pages structured by theme, 2-page executive summary, risk note and quantified recommendations.
4-phase method
- 1
Scoping (days 1-2)
Receive data room, initial doc review, define priority questions on the investor side, plan target team interviews.
- 2
Interviews & analysis (days 3-9)
3 to 8 interviews with the target technical team (CTO, tech leads, ops, security). Code and architecture analysis on deposited data. Vendor and licence cross-checks.
- 3
Contradictory review (days 10-11)
Intermediate readout to the target team to validate facts, identify grey zones, avoid misinterpretation. Written contradictory.
- 4
Report & summary (days 12-14)
Full report writing, executive summary, risk note, live presentation to the investor with a 1-hour Q&A.
Risk axes covered
- Architecture: tight coupling, single point of failure, blocking technical debt
- Security: ANSSI posture, historic incidents, GDPR exposure
- Team: key-person dependency, bus factor, hiring capacity
- Vendors: dependency on a critical SaaS vendor, contractual reversibility
- Roadmap: 12-24 month feasibility vs. current team capacity
- Scalability: capacity to absorb 3×, 5×, 10× current volume
- Compliance: sector (health, finance, regulated) + geographic
- IP & licences: code ownership, open source licences, potential litigation
MAG&Cie guarantees
Single identifiable expert — 10+ years CTO/CPO/RSSI, multi-sector mandates, no outsourced juniors behind the mission.
Contradictory report — the target reviews and challenges the facts before final delivery, avoiding costly interpretation errors.
Strict confidentiality — standard multi-party NDA, isolated data room, data destruction at closing or per your instructions.
Neutrality — no compensation from any party on the transaction, no success fee, no introduction. You pay for the report, not the outcome.
FAQ
How much does a technical due diligence cost?
The market range for an equivalent mission is €8,000 to €40,000 excl. VAT depending on target size, stack complexity and number of interviews. A precise quote is issued after a free 1-hour scoping call.
How long from order to report delivery?
Seven to fourteen business days, including contradictory phase. We can compress to five days in accelerated mode, on a limited-scope target, with a surcharge.
Do we need the target's approval to start?
Yes, in almost all cases. The target must open the data room, allow interviews and sign NDAs. We prepare standard documents and can drive first contact if you want.
What if the target refuses to cooperate?
We can produce an external review (public site, job posts, visible tech footprint, public GitHub if applicable, employee reviews) — useful as a weak signal but no audit value until the target opens its data.
Does the report engage your liability?
Yes: the report is signed, dated, and engages MAG&Cie within the usual contractual limits of a consulting mission (liability capped at mission amount, exclusion of indirect damages, dedicated professional liability insurance).
Can you support post-closing integration?
Yes, on a separate mission. Many investors call us back after closing to run the first hundred technical days of the target or to hire a CTO.
