Proven Impact

LLM Safety Team

  • Need: Stress-test for jailbreaks + leakage.

  • Approach: Red-team suite with seeded exploits & continuous regression.

  • Outcome: 60% reduction in successful jailbreak patterns quarter-over-quarter.

EdTech Evaluations

  • Need: Consistent grading for student code + feedback clarity.

  • Approach: Prompt redesign + structured hints, partial-credit rubric.

  • Outcome: 22% higher learner satisfaction; faster resolution times.

AI Data Platform

  • Need: Validate 100k+ code generations/month across 6 languages.

  • Approach: 40-person EITL pod, test cases + scoring schema, weekly error taxonomy.

  • Outcome: 95%+ rubric adherence; 28% drop in critical errors in 6 weeks.

Talk to us

What Customers Say

A few words from our clients.

“The red teaming suite they developed uncovered vulnerabilities our internal team had missed. Their adversarial prompts and continuous regression testing made our model much more resilient.”

Head of Safety, LLM Lab

“We were struggling with inconsistent grading from our automated systems. The EITL team refined prompts, built rubrics, and ensured human validation. Our learner satisfaction scores jumped significantly.”

VP of Product, EdTech Startup

“Their expert-in-the-loop reviewers became an extension of our own engineering team. Code eval accuracy went up, release cycles sped up, and we finally had the confidence to scale our copilots.”
