“We've been running senior executive search for years. Caliber is the first system that captures how we actually make decisions, and gets sharper with every mandate.”
Leadership Intelligence Operating System
The operating system
for every leadership decision.
A self-improving intelligence layer embedded in your data and workflows. It compounds in value with every decision.
Built and used by
The thesis
From HR software
to organizational intelligence.
Today, search and people decisions run on intuition, CV forwarding, and fragmented systems. A senior mandate consumes 80 to 200 partner hours and 10 to 23 calendar days from brief to shortlist.
- Applicant Tracking Systemsmanage candidates.
- HR systemsstore employee records.
- Performance systemstrack goals.
- Assessment platformsrun surveys.
Caliber sits across the entire decision lifecycle and embeds into the systems you already run. It learns how decisions get made, challenged, approved, and validated by real-world outcomes. The platform adapts to your operating model and turns everyday work into a compounding intelligence asset.
The platform
One workspace.
From brief to ranked shortlist in hours.
Agent workspace. Candidates, rubrics, and AI agents on one surface.
Interview intelligence. Live signals and evidence-cited scorecards.
Succession map. Leadership readiness across the org.
Intelligence layers
One system. Every people decision.
Five layers of intelligence operating on the same substrate: your organization's data, decisions, and outcomes. Every workflow executed makes the next one sharper.
Talent Intelligence
Identify, assess, benchmark, and hire talent at the speed of decision.
Leadership Intelligence
Evaluate potential, plan succession, and design the organization.
Performance Intelligence
Monitor outcomes, goals, KPIs, team effectiveness, and leadership impact.
Incentive Intelligence

Organizational Intelligence
Capture institutional knowledge, decision patterns, and cultural signals.
Agentic workflows
Agents that orchestrate, not just automate.
Specialized agents perform work, coordinate with each other, and continuously learn from how decisions are made, challenged, approved, and validated. The system adapts to your operating model across the entire employee lifecycle.

Built by
A working search firm and an operator studio, building together.
Mike Zurbrügg
CEO & Partner, thirty3
“Every operator we work with at thirty3 has the same blind spot: they make their biggest decisions about people with their worst data. Caliber is the fix.”
Ansuya Ahluwalia
CTO & Partner, thirty3
“We've spent years engineering decision systems for hyper-growth companies. Caliber is the first one purpose-built for the most consequential decisions of all: who you hire, develop, and promote.”
Continuous learning
Every interview.
Every hire.
Every promotion.
Every performance review.
Every leadership success.
Every leadership failure.
Every organization builds its own proprietary intelligence layer. Caliber learns how your firm actually operates: what predicts success, which signals matter, which decisions create the best outcomes. It compounds in value with every workflow executed, every decision made, every outcome observed.
The true value is not automation. It is learning.
Embedded infrastructure
Sits above your stack. Never replaces it.
Caliber agents orchestrate workflows across the systems you already run, with full auditability, explainability, governance, and human oversight. Your existing stack becomes the substrate for an organization-specific intelligence layer.

Enterprise software is shifting from systems of record to systems of organizational intelligence. We're partnering with a small group of forward-thinking firms to shape what that looks like for the next decade of leadership decisions.
