What data leaders say
"Nexus rebuilt our LiDAR ground-truth pipeline in six weeks. Perception regression rate dropped by a third on the next release."
"Their RLHF pool is the only vendor cohort where our rubric agreement held above 0.9 across three model generations."
"KYC document review inside their secure clean room cleared our internal audit with zero findings."
Enterprise controls from pilot to petabyte
Independent audits, regional data residency and human-in-the-loop governance on every workflow.
SOC 2 Type II
Independently audited controls across security, availability and confidentiality.
ISO 27001
Certified information security management system covering all delivery centres.
GDPR
Lawful-basis tracking, DPAs, EU data residency and subject-request workflows.
HIPAA
PHI handling with trained workforce, BAAs and least-privilege access.
