Leadership decisions deserve evidence.

Tessadi is building Veridessa: an evidence layer for the decisions organisations get wrong most expensively. Who leads. Who progresses. Who is ready.

The Problem

Everyone develops leaders. Few can prove it worked.

Organisations invest heavily in leadership development, succession planning and talent decisions. The measurement behind those decisions has not kept pace. 63% of employers name skills gaps as a major barrier to transformation over 2025 to 2030, while training reached only half the workforce last year (World Economic Forum, Future of Jobs Report 2025). The tools most organisations rely on, self-assessment and 360 feedback, capture belief and perception. The decisions they inform demand evidence.

Our Thesis

Evidence-Based Leadership Intelligence.

There is a line that separates leadership data. Below it: what people say about themselves and each other. Above it: what people demonstrably do. Almost every tool in the market operates below the line. Tessadi exists to build above it.

We call the discipline Evidence-Based Leadership Intelligence: observed behaviour, measured to scientific standards, calibrated against what a strategy actually requires.

Veridessa · In Development

One engine. Four questions.

Veridessa is our first instrument: an immersive, multiplayer simulation where leaders make real decisions under realistic pressure, and demonstrated behaviour becomes structured evidence. It is designed to answer four questions, each bigger than the last.

Can this leader deliver?

Individual capability, measured through simulation.

Is the bench deep enough?

Organisational capability, mapped from evidence.

Can we execute this strategy?

Capability calibrated against strategic demand.

Where does the whole organisation stand?

Enterprise-wide capability intelligence.

The Proof is in the Play. Game On.

Veridessa is in active development. That is deliberate: the investors, partners and organisations who engage now shape what gets built.

Why Now

The category is young, fragmented, and about to be regulated.

The market.

Skills intelligence is a growing category with no dominant vendor. The corporate learning and development market around it, estimated at over US$400 billion, is being actively reshaped by AI (The Josh Bersin Company, 2026). Fragmentation at this stage means the category is still up for definition.

The regulation.

Regulators are formalising expectations for AI-assisted people decisions. Across APAC, regulators have moved from voluntary principles to issued rules: advisory guidelines for AI-assisted decisions are in force in several jurisdictions, and profiling now triggers mandatory data protection impact assessment in some markets (IAPP Global AI Law and Policy Tracker, 2026). Evidence-based measurement is becoming the defensible standard.

The gap.

The market maps the skills organisations have. Almost nothing measures what their strategy requires. Veridessa is designed to close that loop.
