New in the June 2026 update — gender leadership is now a single, mutually-exclusive category per company (six in total), applied separately to directors and founders, with a symmetric two-thirds threshold for a “majority”. Every company is placed in exactly one category, so the counts aggregate cleanly.

What is available and how are founders identified?

The Data City’s platform can analyse the leaders and founders of a company. Leaders are the active directors (officers) listed on Companies House. We place every company in one of six mutually-exclusive gender categories based on its active directors — and, separately, on its founders (see below). We identify founders by looking at directors appointed within 2 years and 28 days of a company’s incorporation. We add a 28-day buffer to account for standard administrative reporting delays permitted under UK corporate law. Specifically, the Companies House “14+14” rule grants a company up to 14 days to update its internal register of People with Significant Control (PSC) following an appointment, and an additional 14 days to formally submit this information to the public register. Founders are specifically a person with significant control and they are still an active director at the company. A person of significant control is defined by Government. In short it means a person likely has voting rights, shares, or a controlling influence in a company. Companies are required to declare persons of significant control. It is possible to have information protected, however.

How we categorise leadership and founders

Gender is assigned from each officer’s Companies House title (e.g. Mr, Mrs). Titles without a gender (e.g. Dr, Prof) count as unknown and are still included in the total. The Data City does not use machine learning, and never uses names, to estimate gender. Each company is placed in exactly one of six categories, based on the share of active directors with a female-gendered title (X) or a male-gendered title (Y):
CategoryDefinition
All women ledX = 100% — every active director has a female-gendered title
Majority women led66.7% < X < 100% — more than two-thirds, but not all
Mixed led33.3% ≤ X ≤ 66.7% — between a third and two-thirds have a female-gendered title
Majority men led66.7% < Y < 100% — more than two-thirds, but not all, have a male-gendered title
All men ledY = 100% — every active director has a male-gendered title
Uncertainnone of the above — including companies with no active directors, and boards where unknown-gender titles mean the category can’t be determined without guessing
The percentages are rounded for display; the boundaries are applied as exact thirds, so there is no rounding drift. A clear majority (more than two-thirds, but not all) is only possible on a team of four or more, so most companies fall into All, Mixed or Uncertain rather than a Majority category. The same six categories are applied separately to a company’s founders (using the share of founders with each title).
Because the categories are mutually exclusive, every company sits in exactly one — so you can aggregate them safely (for example, “women-led businesses are X% of companies”). A company is women led when it is All women led or Majority women led — i.e. more than two-thirds of its active directors have a female-gendered title.
Why “Uncertain”? If a company has, say, two women, four men, and one director with an unknown-gender title, that final title could tip the company into either Mixed led or Majority men led. Because we never guess gender from a name, the honest answer is Uncertain.
In some instances we are not able to identify founders, or identify the genders of founders.Firstly, we rely on persons of significant control from Companies House. Persons of significant control is legislation that was introduced in 2015 and our ability to identify founders before then is reduced. An example is included in appendix one. In addition, sometimes the true founders of a company are not listed as persons of significant control, because of their initial level of equity in a company not meeting the threshold for significant control. Lastly, we are not able to identify the gender of a founder (or leader) where they have used a unisex title — these companies fall into the Uncertain category.In both leader and founder data, gender is based on the declared titles of officers on Companies House. Data City does not use machine learning to estimate the gender.You should be careful when using this data to compare summary statistics between men and women led (or founded) businesses. We recommend you remove outliers from your analysis.

Where is the data?

ANALYSE

In ANALYSE, you can find gender data in the analysis summary box and in the company details panel. In the company details panel, the Gender section shows two 100% stacked bars — the founder gender mix and the director gender mix — each split into the six categories above. This communicates the proportion of companies in your list that are women led, men led, mixed, or uncertain, for both founders and directors.

EXPLORE

In EXPLORE, you can find gender data in the people tab of each company page, under the Woman led statistics header. This includes the women founder and women officer counts, whether the company is women led, and the company’s director and founder gender categories.

Filtering

In ANALYSE and EXPLORE you can filter companies by any of the six categories — separately for directors (leaders) and for founders. Ticking more than one category in a group returns companies in any of them. These options are available under the company filter.
In November 2023 we wrote an article detailing definitions, coverage and drawbacks of this approach.

Appendix one: ANN SUMMERS LTD. (01034349)

As per Ann Summers’ website:
10th December 1971, the first Ann Summers shop opened in Marble Arch. Their Executive Chair, Jacqueline Gold, joins her dad’s business as an intern with a brilliant idea - Tupperware parties, but for Ann Summers Product. The Ann Summers party is born.
On Companies House, their incorporation date is 10 December 1971. However, on Companies House, their earliest officer (director) is David Gold who was appointed “before 1991”:
image png Sep 17 2025 12 28 42 9112 PMThere are two issues here for founder analysis using Companies House data:
  1. We do not know the exact year David was appointed as a director.
  2. The incorporation date is 20 years before the director appointment date.
So although it’s quite clear from the website, it’s unclear using the data hence why we are unable to identify any founders regardless of gender:
