How to Find a Private Company's Employee Count
By Kooperativa Engineering
To find a private company's employee count, collect three or four independent signals and report a range. A private company usually has no single published figure the way a US public company has one in its annual report. The signals are what the company says about itself, what a government size test or programme records, how many people list the company as their employer, and how many roles it is hiring for.
Each signal counts something different, so the skill is not finding the number. It is knowing what each source measures and saying so when you report it.
Start with what the company says
The About, Careers and press pages, and funding announcements, often give a figure or a band such as a team of about 50. It is self-reported, usually rounded and tied to the day it was written. Treat it as the ceiling check for the other signals, not as the answer.
Government sources and their limits
In the UK, the Companies House guidance treats the average number of employees as one of three size tests. For periods starting on or after 6 April 2025, a micro-entity has no more than 10 employees on average and a small company no more than 50, alongside turnover and balance sheet limits. The test places a company in a band. It does not hand you a count.
In the US, the E-Verify Employer Search shows a workforce size for employers enrolled in the programme, as long as the employer reported at least five employees. The employer reports the figure when it enrols, and the search only covers enrolled employers. The official page was last updated in September 2024.
People and jobs as proxies
Counting the professional profiles that list a company as the current employer gives a floor, not a total. It misses people who keep no profile and roles where profiles are rare. Job postings measure hiring, which is a change over time and not a stock. Use both as signals about the floor and the direction, not as the count.
| Signal | What it tells you | Main limit |
|---|---|---|
| Company website or press | A self-reported figure or band | Rounded, unaudited, tied to a date |
| UK size tests | A size band | A band, not a count |
| E-Verify Employer Search (US) | Reported workforce size of enrolled employers | Self-reported, enrolled employers only |
| Professional profiles | A floor for current staff | Misses people without a profile |
| Job postings | Hiring pace | Not a headcount |
What our API returns for a private company
The company endpoint returns the company record, including its headcount, and the current employees endpoint returns a total for the people attached to the company. Both describe indexed profiles, so read them as the floor signal in the table above. For a private company with no filing, that floor is useful because it is measured the same way for every account you look up.
Report a range and name the source at each end
Put the lowest credible signal at one end and the highest at the other, and write down where each came from and when. For example, if profiles show 120 current staff and the company page states 150 to 200, report 120 to 200 and name both sources. A range with its sources can be defended in a meeting. A single number cannot.
Frequently asked questions
Can you find the exact number of employees at a private company?
Rarely. Most sources give a band or a floor, so the honest answer is a range with the source of each end.
Is the size range on a company page reliable?
It is self-reported and rounded into a band. Use it as a ceiling check and compare it with a count of current staff.
