Serious work, generous colleagues.

Here, rigor and kindness work together. Review is constructive, questions are welcome and nobody has to guess what good looks like.

A day on an engagement.

    Thirty minutes on a new prompt-injection technique.

Questions are welcome at every level.

How we treat each other.

Review culture

Challenge the work, respect the person

Specific, reasoned reviews at every level, including when juniors question seniors.

Inclusion

Different backgrounds, better assessments

We recruit on evidence of capability, not pedigree. Ask us for any adjustment you need.

Wellbeing

Planned, not heroic

Fieldwork peaks are planned and staffed, never absorbed in silence.

Flexibility

Work where it is best done

Fieldwork happens where the client needs it. The rest happens where you do your best thinking.

Ethics

Permission is everything

Every test runs under written authorization. Anyone can stop out-of-scope work.
