The verification you're already paying for.
Verification and evidence consume 50–70% of a DO-178C program. Dextra attacks that bucket. Here is the math — modeled, deliberately conservative, and traced to primary cost-of-defect and certification-effort benchmarks.
Illustrative models, not customer results — Dextra is pre-revenue.
How the model works
- Fully-loaded senior safety-critical engineer ≈ €160,000/yr (≈ €730/day). Only certification-relevant engineers are counted — the most conservative denominator.
- Conservative reductions, each tied to a mechanism: −30% verification/evidence (DO-333 lets formal proof replace test campaigns), −30% requirements-driven rework (NL→TCTL catches ambiguity at the 1× phase), −30% certification documentation (artifacts generated from the verified model).
- NPV at a 10% discount rate over 5 years. Certification-timeline compression and late-integration savings are deliberately NOT monetized — withheld upside.

These are modeled estimates, not measured outcomes. The reductions are Dextra's own conservative planning assumptions, each tied to an engineering mechanism rather than asserted. The models withhold real upside: certification-timeline compression is not monetized, late-integration and engineering-change savings are set to zero, and only certification-relevant engineers sit in the denominator. The three cases land in a tight 23–25% program-cost-reduction band precisely because the same assumptions are applied to each — not tuned per segment. Full methodology and every calculation live in the strategy dossier.
