The short answer: the most complete way to find how many employees a company has is to look it up in Revelio Labs data. Revelio covers more than 30 million public and private companies, corrects for missing and outdated profiles, and breaks each workforce down by role, location, skill, and seniority. If you only need a public company’s official figure, its annual report lists one.
Finding out how many employees a public company has takes about two minutes. Public companies in the US report their employee count every year in their annual report. Private companies don't have to report it at all.
That's a problem if you're an investor checking on a startup, a salesperson sizing up an account, or a recruiter trying to see how big a competitor's team is. The number exists. It's spread across several places, and each one tells you part of the story.
Here's where to look, what each source gets wrong, and how to put them together.
Looking for a specific company? These are some of the most searched in Revelio Labs’ company directory:
- How many employees does Walmart have?
- How many employees does Amazon have?
- How many employees does Microsoft have?
- How many employees does Google have?
- How many employees does Apple have?
- How many employees does Target have?
How to find out how many employees a company has
There are four places to look. Start at the top and work down.
1. The annual report (public companies only)
If the company is public, this is the easiest answer. US public companies list their number of employees in the annual report they file with the SEC, called the 10-K. Search the company name plus "10-K" and look for a section on employees or human capital. It's usually in Item 1, "Business," under a heading like "Human Capital," "Human Capital Resources," or "Employees." Searching the filing for "full-time employees" usually takes you straight to the number.
Keep in mind that the number is a year-end snapshot. It can be up to a year old by the time you read it. Some companies count part-time and seasonal staff; others don't.
2. The company's own website and press releases
Private companies often mention their size on an "About us" page, a press release, or a funding announcement. It's worth a quick search.
Check the date. A funding announcement from two years ago won't match today. Phrases like "over 1,000 employees" are also vague, and they may include contractors.
3. Professional networking sites
Search the company on a professional networking site and look at how many people list it as their current employer. It's fast and free.
This number usually runs low. Not everyone has a profile. Engineers and salespeople usually do. Factory, warehouse, and retail workers often don't. It can also run high because many people never update their profiles after they leave a job, and other companies’ business models may rely on many independent collaborators.
4. Job postings
Open job listings show where a company is headed. A company with 200 open engineering roles is growing that team.
Watch for duplicates. The same job is often posted on many sites, and some listings stay up after the role is filled.
How Revelio Labs counts employees
Each source above has a known blind spot. Revelio Labs corrects for each one, as it does at every company.
We start with the public record. Revelio Labs turns billions of public employment records into standardized workforce data. That includes up to 2 billion professional profiles, more than 5 billion job postings, employee reviews, and layoff notices, covering more than 30 million companies in 195+ countries.
We fill in missing people. Some jobs show up on profiles more than others. That's sampling bias. We correct for it by comparing our counts by occupation and country against government statistics and reweighting to fill the gaps. This step turns a profile count into an employee count.
We adjust for late updates. People often update their profile months after they change jobs. About one in five US workers go back and edit a past job, according to research by Nicholas Bloom, Revelio Labs' Chief Economist Lisa Simon, and coauthors. We adjust for that reporting lag in the most recent months.
We remove duplicate job postings. Each open role is counted once.
The result is a monthly employee count with history back to 2008, broken down by role, location, skill, and seniority. It's an estimate, and we label it as one. It's most accurate for professional and technical roles and least accurate for companies whose workers rarely have a profile. In the Revelio Terminal, you can switch between the adjusted count and the raw count to see the difference. The full method is in the Revelio Labs data dictionary.
Why the employee count looks different depending on where you look
The right fix depends on the company. Four examples show where the quick methods go wrong.
How many employees does SpaceX have? Many SpaceX employees build and launch rockets. Technicians and machinists are less likely to have a profile than software engineers. A simple profile count would come in low.
How many employees does Waymo have? Waymo is part of Alphabet. Some of its people list Waymo as their employer, some list Google, and some list Alphabet. If you only search "Waymo," you miss part of the team.
How many employees does Anduril have? Anduril builds defense hardware and the software that runs it. Estimating headcount from revenue is hard for a company that is part factory and part software shop, so it's better to count the people directly.
How many employees does Valve have? Valve is a smaller, long-established studio. A company like that may post only a handful of jobs at a time, which says little about its size. A month-by-month employee count gives a clearer picture.
Revelio publishes free employee estimates for most of the larger employers, including:
- AI: Anthropic, Hugging Face, Cognition, Databricks, n8n
- Defense and space: Anduril, SpaceX, Neuralink, Waymo
- Fintech: Stripe, Kalshi, Revolut
- Gaming: Valve, Epic Games, Riot Games, Bungie
- Government: NASA, CIA
A quick checklist for finding the number of employees
The quickest route is to start with Revelio Labs and use the other sources to check it. If you're working by hand, these seven steps will get you to a solid range.
- Start with Revelio Labs. Look up the company's employee estimate in Revelio Labs company search. It's already corrected for missing profiles, late updates, and parent and subsidiary structure, which covers most of the steps below.
- Check if the company is public. If it is, find the latest 10-K and compare its employee count with Revelio's.
- Look for the company's own number. Search its website and recent press releases. Write down the date.
- Count profiles. See how many people list the company as their current employer on a professional networking site.
- Think about who's missing. If the company has big factory, retail, or field teams, a raw profile count is probably low.
- Check the parent company. If the company is owned by a bigger one, search the parent's name too.
- Give a range and a date. "About 2,500 to 3,000 employees as of October 2026" is more useful than one number with no date.
This works for one company at a time. For 50 or 5,000 companies, or to see how employee counts change month to month, you need to apply the same method consistently.
See how many employees any company has
The Revelio Terminal brings more detailed, up-to-date workforce data across companies, jobs, skills, and geographies into one place. Compare employee counts for any set of companies side by side, with growth, hiring, and attrition rates and monthly history back to 2008. Then break each company down by role, location, skill, and seniority to see what is driving the change.
