Three years in. No filler engagements.
Lionsrock was built from day one to work on the hardest AI and data privacy problems in enterprise — by advisors who spent decades inside the institutions we now advise.
Three years old. Zero filler clients.
Lionsrock was founded in 2023 by operators who had spent careers inside the enterprises they now advise — as Chief AI Officers, Chief Privacy Officers, and heads of data engineering at institutions where a bad AI decision doesn't just cost money, it costs trust. We started the firm because we kept seeing the same pattern: organizations deploying AI fast and governing it slow.
In three years we've worked with a deliberately small number of clients. That's not a constraint — it's the model. Every engagement gets our full attention, our honest assessment, and our accountability long after the final presentation. We don't do retainers for the sake of retainers. We stay until the problem is solved.
Principles we don't compromise on.
Accountability over activity
We measure ourselves by outcomes, not deliverables. In AI and data work, that means owning the downstream consequences of what we recommend — not just the architecture diagram.
Candor over comfort
We tell clients what they need to hear. If your AI program has a fairness problem, a privacy exposure, or a governance gap — you'll hear it from us before you hear it from a regulator.
Depth over breadth
AI and data privacy are not areas where surface-level advice is safe. We go deep on each engagement so our clients get judgment, not just frameworks.
