AikaGraph is a data visualization method for networked, time-based information, built to make relationships and anomalies visible instead of leaving them buried in a list or a flat chart.
I'm the product of parents who never married, and my father wasn't part of my early life. That absence is what sent me looking into my family history in the first place. A search in December 2014 turned up a memorial a cousin had posted for my paternal grandmother, who had just passed away. It moved me enough to reach out, and that contact pulled me into genealogy in earnest.
That side of the family resolved cleanly for about six generations. My mother's side got difficult a few generations out. Working back through that line, I ran into a wall other researchers of the same family had also hit: two ancestors, close enough in name and dates to be mistaken for each other, had been folded into a single person across most of the public family-tree records, an error blocking any further progress.
It's a common failure mode in genealogy: names repeat across generations, dates overlap, and the tools most people use to record and share family trees have no good way of showing when two records that look almost identical are actually two different people.
I worked the problem by hand first, sketching the relationships on paper, then building a simple physical model I could turn and look at from different angles. That's what finally made the error visible: the two ancestors weren't one person misdated, they were two people from different generations whose records had been merged because the tools available couldn't represent the structure clearly enough to tell them apart.
That was the moment the idea behind AikaGraph started, well before it had a name. Existing tools for visualizing relationship data are cumbersome, and they routinely miss exactly the kind of hidden relationship, and hidden error, that had stalled my own research and everyone else's on that family line. I started developing a different way to represent that kind of data, aimed at making relationships and anomalies visible instead of leaving them buried in a list or a flat chart.
That approach is what became AikaGraph: a patent-pending method for exploring networked, time-based data that reveals structure and inconsistency a conventional tree or table hides. The genealogical puzzle that started it all remains the clearest example of the kind of problem the tool is meant to solve.
I'm now extending that same method into AikaGraph Health, a clinical-data application currently in development. That's not a pivot away from the genealogy work so much as a return to where I started: roughly 27 years in healthcare IT before AikaGraph existed at all, data integration, EHR/EMR systems, HL7, and HIPAA-governed clinical pipelines. The genealogy puzzle proved the method works on messy, real-world relationship data; the healthcare background is what tells me it belongs there.

Finnish Patent and Registration Office (PRH), application no. 20265748, filed 2026-06-30. Title: "Interactive data visualization and analysis tool for multistream time-series data." Applicant: Ulf Freyjadis.
The underlying method was built around networked, time-based relationship data broadly. Genealogy is its first public, working example, not the limit of what it applies to.
Specific scoring, weighting, and internal implementation details remain trade secrets and aren't discussed publicly. Technical or commercial due-diligence conversations happen under NDA. See Investors & Business Finland.
The clearest way to understand AikaGraph is to watch it turn a real, messy family file into one explorable structure. That's exactly what the private beta is for.
