We are building Veridessa because 'we think they're ready' was never good enough, for the organisation or the leader.
Tessadi is an enterprise technology company building Evidence-Based Leadership Intelligence. We exist because the most consequential decisions organisations make, who leads, who progresses, who is ready, are still made on the weakest evidence.
A repetitive pattern that became impossible to ignore.
Across the organisations we worked in and with, the same pattern repeated: serious investment in leadership development, sincere effort, and no defensible answer to 'did it work?' The tools measured belief and perception. The decisions needed behaviour. Careers, successions and strategies were being decided on instruments never designed to carry that weight. So we set out to build the instrument we kept wishing existed. And it was rarely only the organisation flying blind: the leaders themselves seldom had an objective read of how they actually led, only feedback to argue with and instinct to second-guess. The instrument had to serve both, the organisation making the call and the leader who wants to see themselves clearly.
Evidence-Based Leadership Intelligence.
Leadership decisions deserve the evidential standards expected in finance, engineering and risk. There is a line separating leadership data: below it, what people say about themselves and each other; above it, what people demonstrably do. Nearly the entire market operates below the line, inferring capability from resumes, activity and opinion.
Tessadi builds above it: observed behaviour, measured to the standards of assessment science, calibrated against what a strategy actually requires, and governed for the regulatory direction APAC is already moving in. We are not competing in leadership assessment. We are defining a discipline.
The same evidence cuts both ways. It gives an organisation a defensible basis for the decisions it cannot afford to get wrong, and gives an individual leader an objective mirror to develop from, rather than a negotiation between contradictory feedback and their own instinct. We set out the full argument in The Line Through Leadership Data.
We spent our careers making these decisions. That is why we are building the instrument.
Tessadi's two founders have spent a combined 40+ years inside global organisations, running the exact decisions Veridessa is built for: C-suite succession, CEO-level recruitment across five countries, high-potential identification, executive calibration, and M&A leadership integration at up to 25,000-employee scale.
We have chaired the succession reviews. We have defended the high-potential lists. We know precisely where the evidence runs out and judgement takes over, because we lived at that boundary for two decades each.
Our credentials, a Chartered CIPD Fellowship, ICF and EMCC-accredited senior coaching certifications, PMP and PMI-ACP, and two MBAs, are the formal record. The conviction came from the rooms. We introduce ourselves in person, where the conversation belongs.
The advisory work is where the problem was found.
Tessadi brings evidence discipline to leadership, workforce and organisation decisions. We do that in two ways. We advise organisations directly, on workforce utilisation and planning, organisation development, operating-model and role design, capability assessment, succession and readiness. And we are building Veridessa.
The order matters. The advisory work came first, and doing it repeatedly is what exposed the gap: the decisions that carry the most weight are made on the weakest evidence. Veridessa is the instrument we are building to close it. One is where the problem was found. The other is the attempt to solve it.
How we operate.
Evidence before claims.
We will not claim validity our evidence does not yet support. Validation is a process, and we publish where we are in it.
Governance as architecture.
Data protection and responsible AI are design inputs, not legal reviews at the end.
Direct, human, selective.
No automated sequences. Every conversation is with the people building the product.
