How to Find Competitor Revenue: 10 Sources and How Wrong Each One Is

Every source for competitor revenue sits in one of three tiers, and confusing them is the reason so much competitive analysis is quietly wrong. Filed figures are audited and submitted to a regulator. Stated figures are what the company has said about itself in public. Estimated figures are models, whether yours or a data provider’s. A report that mixes all three in the same font is worse than no report.

Notice how the reliability column collapses toward the bottom. That is not a flaw in the research, it is the actual shape of the problem: outside a filing obligation, nobody knows a private company’s revenue except the company.

1. 1Decide what precision you actually need. "Bigger or smaller than us" needs a completely different method from "what is their ARR to the nearest million". Most real decisions need the first, and chasing the second is where weeks disappear.
2. 2Check whether they file. Public companies file with the SEC or their local regulator. Private companies across most of Europe file annual accounts too, which surprises anyone trained on US-only advice. Search the registry for the operating entity, not the brand name.
3. 3Collect what they have said themselves. Founders announce ARR milestones, funding press releases carry growth claims, and recruitment ads quote scale. All of it is unaudited and self-selected, so treat it as a ceiling rather than a fact.
4. 4Build the number bottom-up. Estimate customer count from logo walls, review volume and case studies, then multiply by a price you have already verified. Show your working, because the assumptions are what a reader will want to argue with.
5. 5Sanity-check with a second method. Run headcount times revenue per employee for the same company. If the two methods disagree by more than roughly a factor of two, one of your assumptions is wrong and it is usually the customer count.
6. 6Label the confidence on every figure. Mark each number Filed, Stated or Estimated. A report that mixes an audited figure with a model and prints both in the same font is worse than no report at all.
7. 7Re-check on their filing calendar. Set the review for when the next accounts or quarterly report is actually due, rather than an arbitrary date in your own calendar.

Almost every article about finding a private competitor’s revenue is written from a US perspective, where private companies genuinely do not have to publish anything. Apply that assumption to a European competitor and you will estimate a number that was available as a filed fact all along.

Filing obligations, thresholds and the level of detail vary by country and by company size, and small companies can often file abridged accounts that omit the profit and loss statement. But the accounts themselves are public, searchable, and free or nearly free in most jurisdictions.

1. SEC EDGAR filings

For any US-listed competitor, full-text search on EDGAR gets you the 10-K and 10-Q with audited revenue, usually broken out by segment and geography. The segment breakdown is the part worth your time: total revenue tells you their size, while the segment table tells you which part of the business is actually growing and therefore where they will invest next.

2. National company registries

Covered in full above. Check this before anything else, because it converts the entire exercise from estimation to lookup.

3. Their own public claims

Founders announce milestones on podcasts, at conferences and in hiring posts. Search for the company name alongside “ARR”, “revenue”, “crossed” and “milestone”, and check any recruitment page, which frequently quotes scale to attract candidates. These claims are unaudited, self-selected and timed to flatter, so record them with the date and the speaker, and treat them as a ceiling.

4. Funding announcements

A raise usually comes with a press release, and often with a growth claim attached. The raise amount itself is not revenue, but it bounds the burn they can sustain, and the valuation sometimes implies a revenue multiple if the round is discussed in the trade press. Useful as a cross-check, never as the figure.

5. Public contract awards

If they sell to government, a portion of their revenue is published with the buyer, the value and the term. It is partial by definition, but it is exact, and for competitors focused on the public sector it can account for a large share of the total.

6. The bottom-up build

This is the method worth learning properly, because it is the only estimate whose assumptions you can defend line by line. Estimate the customer count from named logos, review volume, case studies and any figure they publish, then multiply by an average contract value you derived from their actual pricing. Write the two inputs down explicitly. When somebody disagrees with your number, they will be disagreeing with an assumption you can then discuss, which is a far better conversation than defending a total.

7. Headcount times revenue per employee

The widely repeated shortcut is to multiply employee count by something between $100,000 and $300,000 depending on funding stage. It is fine as a plausibility check and poor as an estimate, because revenue per employee varies by several times with sales motion, offshore ratio and how much of the workforce is contracted. If your bottom-up build and this method disagree by more than roughly a factor of two, go back and check your customer count.

8. Data provider estimates

Crunchbase, Owler, ZoomInfo and Dun & Bradstreet all publish revenue bands. They are models, which is why they are presented as ranges, and they degrade badly for small private companies where the model has little signal to work from. Use one as a third opinion that either agrees or disagrees with your own build.

9. App store revenue estimates

For mobile-first competitors, app intelligence services model revenue from ranking and download data. Directionally useful for tracking one app over time, unreliable as an absolute, and blind to any revenue arriving outside the store.

10. Your own market position

You already know something no database does: how often you meet them, and how often they win. If you compete in 200 deals a year and they take 60 of them, you can size their revenue in your segment directly from your own average contract value. It is the narrowest estimate on this list and frequently the most decision-useful, because it is scoped to the market you actually sell in.

1. 1Label the tier. Write Filed, Stated or Estimated next to every number, every time. This single habit does more for the credibility of a competitive report than any amount of extra research.
2. 2Check you are comparing like with like. Recognised revenue from filed accounts and a founder’s stated ARR are different measures: one is audited and backward-looking, the other is a forward run rate. Ranking competitors on a mixture of the two produces an ordering that is an artefact of your sources.
3. 3Run a second method. Two rough methods that agree are far more trustworthy than one precise-looking figure from a database. If they disagree, the gap tells you which assumption to attack.
4. 4Check the period and the currency. Filed accounts often cover a fiscal year ending mid-calendar, and a European filing is in euros or pounds. Converting at today’s rate rather than the period average quietly moves the number.

Company registers and regulatory filings exist precisely so that anyone can read them. Reading them, downloading them and republishing figures from them with attribution is entirely legitimate. The constraints are narrow and worth stating plainly.

• Do not obtain financial information through misrepresentation, including posing as an investor, a journalist or a prospective partner.
• Do not use figures you received under a confidentiality obligation, including from a former employee of the competitor. Their obligation survives their employment.
• Do not publish an estimate in a way that implies it is audited. Stating a modelled figure as fact about a named company is a reputational and, in some jurisdictions, a legal risk.
• If you are handling material non-public information about a listed competitor, stop. Securities law is a different and much sharper problem than competitive research.

• Their ARR, for a private company. It is a management metric and is almost never filed. Proxy: a dated public claim by the company, or your own bottom-up build.
• Revenue by product line. Only listed companies segment, and only where the segment is material. Proxy: headcount distribution across product teams from their job board, which tracks investment rather than revenue but moves first.
• Churn and net revenue retention. Near-unknowable from outside, and the figure that most determines their trajectory. Proxy: logos that disappeared from their customer page, and the volume of recent negative reviews. See how to find a competitor’s customers.
• Profitability, for many small filers. Abridged accounts can legitimately omit the income statement. Proxy: headcount growth against funding raised, which indicates whether they are spending ahead of revenue.

Revenue data arrives on a schedule, which makes it one of the easier things to keep fresh: set the review for when the next accounts or quarterly report is actually due rather than an arbitrary date. Between filings, the things that move your estimate are funding rounds, layoffs, acquisitions and pricing changes, and all four are announced publicly.

Record each figure with its tier, source and date in a competitor profile, so the next person to ask “how big are they?” gets an answer with its working attached rather than starting again.
