Start from the decision, not the title
Most lists of "decision makers" are really lists of senior titles, which is why so much outreach reaches somebody with no budget for the thing being sold. A title describes a position; a decision has an owner, a payer and a user, and they are often three different people.
Write the decision down in one sentence before looking anybody up. "Who signs a twelve-month subscription for competitor monitoring" produces a different list from "who is senior at this company".
- The economic buyer - who releases the budget. Usually a function head below a certain figure and a CFO above it.
- The functional owner - whose team the thing lands in, and whose numbers it is meant to move.
- The practitioner - who will use it daily. Rarely the signer, often the person who kills it.
- The blocker - security, legal or procurement. Not a buyer, but able to stop one.
Where a company names its own people
These are the dated documents a company issues about its own people, in roughly the order they are worth reading. Each one is dated, which matters more than it sounds: an org chart that was right eighteen months ago is worse than no org chart, because it reads as current.
- The leadership or team page. States the function each person owns, in the company words.
- Appointment announcements. A newsroom post or a trade-press piece naming a hire states the remit, the reporting line and the date.
- Regulatory filings, where applicable. In the US, officers and material changes are filed and dated.
- Job postings. A posting for a role that reports to someone names that someone, and the shape of a team can be read from what it is hiring.
- Conference and webinar listings. Speakers are listed with the title the company gave them that month.
How to tell a title from authority
Two people with the same title at two companies can have very different authority, and the difference is usually visible in what the company has said about them rather than in the title itself.
- Does anything name them as owning a budget, a P&L or a function, rather than a team?
- Do other announcements route through them - do new hires in that area report to them?
- How recent is the appointment? A leader in their first ninety days is forming a view and is reachable in a way they will not be in month ten.
- Is the function new? A first-ever head of a discipline almost always has a mandate and a budget attached.
What changes when the decision maker changes
A leadership change is the most actionable thing on this page, and the most perishable. A new functional head typically reviews what they inherited inside the first quarter, which is the one window where an incumbent supplier and a newcomer are briefly on equal terms.
The practical consequence is that a decision-maker list is not a dataset you build once. It decays, and it decays fastest exactly where it matters most.
How to keep it current without rebuilding it
Re-reading every account every month is not realistic by hand, and it is why most teams keep a list that is quietly wrong. This is the part worth handing to an AI research agent: not finding a name once, but noticing the day that name stops being right. The practical approach is to watch for the events that invalidate an entry rather than re-checking entries on a schedule.
- A named appointment, departure or remit change in the function you sell into.
- A reorganisation mentioned in a filing, an announcement or a careers page restructure.
- A job posting for the role you had recorded as filled.
- A speaker listing giving someone a title you do not have on file.
