We make mission-critical systems work.
For organisations where a wrong call is expensive.

What We Do
Before you bid, build, launch or apply: with the FIT Delta Assessment, we map your existing assets against target requirements to quantify risk, scope and feasibility in days, not weeks. The result is the exact technical delta, giving leadership the clarity to decide, price and execute with certainty.

How We Work
Extract the Target.
Requirements, criteria or regulation, broken down into a structured form, each clause traceable to its exact source.
Map the Reality.
Elicited in the room with the people who actually run the system: field knowledge no document contains, validated by them, not assumed on their behalf.
Quantify the Delta.
Every gap held to the same standard as the target: traced to its source, not softened into a generic risk label.
Decide and Execute.
Turned into Visual Clarity: something leadership can actually see and act on, not another report to file away.
Delivery
A decision is only as good as its execution. Where projects call for it, we lead delivery ourselves: aligning stakeholders and interface partners, protecting the way of working, and carrying full responsibility for risk and quality through to completion.
Available as interim technical leadership, Lead System Engineer or programme recovery for critical projects already underway.
About
Function Is Truth is the practice of Thomas Obermayer.
Twenty‑five years of engineering across mission‑critical infrastructure: traffic and broadcast systems, tolling, telematics, commercial IT/OT operations and high‑end cine engineering. The last ten in leadership roles, carrying full responsibility from concept to delivery.
A key focus has been leading complex, international projects and cross‑company partnerships across Europe, the Middle East, the US, and Asia‑Pacific. Where different corporate cultures, languages, and system architectures intersect, we establish methodological clarity and resilient interfaces.
Engagements have spanned national broadcasters, global infrastructure operators and specialist manufacturers, alongside workshops for public institutions and financial‑sector clients, all under confidentiality that precludes naming them individually.
That experience is codified into the FIT Delta Assessment: a repeatable framework built on structured elicitation and domain modelling. Where it helps, graph‑based tooling and generative AI accelerate the work and make it auditable; they don’t replace it. The result: complex existing assets mapped against strict targets, turning months of architectural discovery into rapid, audit‑proof decisions.
Where engagements carry strict confidentiality or NDA obligations, cloud tooling is often not an option. In those cases, we deliver on Sovereign AI: fully on‑premises, air‑gapped systems, developed with independent academic AI‑research expertise.
Also trained as a photographer, a visual thinker by instinct. We call this Visual Clarity: turning complex systems into something people can actually see and decide on.
