Selling to Private Companies When You Cannot Find Their Revenue
Private companies make up the vast majority of the B2B market, and most of them do not publish revenue figures. No annual report, no SEC filing, no earnings call transcript. For salespeople accustomed to qualifying prospects by revenue, this creates a real problem. You cannot size the deal if you cannot size the company. Or at least, you cannot size it the way you are used to.
But revenue is just one proxy for what you actually care about: budget capacity, organizational complexity, and willingness to spend. And there are dozens of other signals that get you close enough to qualify a prospect, price a solution, and forecast a deal without ever seeing a P&L statement.
Employee Count: The Most Accessible Proxy
Employee count is the single most useful proxy for company size when revenue is unavailable. It is public on LinkedIn, often accurate within a reasonable range, and correlates reasonably well with operational complexity and budget capacity. A 50-person company and a 500-person company have fundamentally different needs, processes, and spending thresholds, and that distinction alone shapes your sales approach.
More than just the total number, the distribution of employees across functions tells you about the company's priorities. A 200-person company with 100 engineers and 20 salespeople is a product-led organization. The same-sized company with 40 engineers and 80 salespeople is a go-to-market machine. These differences affect who your buyer is, what they value, and how much they are likely to spend on your category.
Tracking employee count over time reveals growth trajectory. A company that grew from 100 to 200 employees in a year is on a very different path than one that has been at 150 for three years. Growth velocity is often a better predictor of buying behavior than absolute size because growing companies are actively investing in infrastructure, tools, and processes.
Office Footprint and Geographic Presence
Physical office locations are public information that reveals more than most people realize. The number of offices, their locations, and their relative sizes tell you about the company's operational scope and market reach. A company with offices in San Francisco and London is operating at a different scale than one with a single location in a secondary market.
Office upgrades and relocations are particularly useful signals. Moving from a co-working space to a dedicated office suggests growth and stabilization. Opening a second location suggests market expansion. Moving from a small office to a larger one in the same city suggests the company is scaling its team. These are all positive indicators for budget capacity and willingness to invest in operational infrastructure.
Advertising and Marketing Spend
Companies that spend money acquiring customers have revenue. The level and sophistication of their marketing efforts give you a rough sense of scale. A company running Google Ads, sponsoring industry conferences, and producing professional content is investing significantly in customer acquisition. That investment implies revenue to support it and budget discipline to manage it.
Digital advertising spend is partially visible through competitive intelligence tools. Social media ad libraries, SEM analysis, and sponsorship tracking all provide directional data on how aggressively a company is marketing. A private company spending heavily on acquisition in your market is probably larger and better-funded than their lack of public financial data suggests.
Technology Purchases as Budget Indicators
The tools a company uses tell you about their budget thresholds. A company running Salesforce Enterprise, Snowflake, and AWS is spending six or seven figures annually on technology. A company using free tiers and open-source alternatives is managing costs more carefully. Technology stack analysis gives you a surprisingly accurate picture of a company's spending behavior and budget range.
This is especially useful for pricing conversations. If you can see that a prospect already pays for expensive tools in adjacent categories, you know their budget tolerance. You can price accordingly and justify the investment by reference to what they are already spending. If their stack is entirely budget tools, you know to lead with ROI and cost-efficiency arguments.
Partnership and Customer Announcements
Companies announce partnerships and major customer wins for marketing purposes, but these announcements also reveal business scale. A company that partners with a Fortune 500 is operating at a level of sophistication and scale that smaller companies cannot sustain. A company that announces a government contract has passed compliance and security requirements that filter out small or immature organizations.
Customer logos on a company's website are another signal. The types of customers they serve indicate their own operational maturity and likely revenue range. A company serving enterprise clients has enterprise revenue. A company serving small businesses probably has corresponding scale.
Funding History and Investor Profile
For companies that have raised venture capital, the funding history is a strong size indicator. Total funding raised, combined with the time since the last round, gives you a rough envelope for the company's current scale. A company that raised a $50 million Series C three years ago either has significant revenue by now or is in trouble. Either scenario is useful information.
The identity of the investors matters too. Tier-one venture firms at the growth stage invest in companies with meaningful revenue traction. The round size and investor caliber together give you a directional revenue estimate that is often accurate enough for sales qualification purposes.
Combining Signals for Accurate Sizing
No single proxy is perfect, but combining several gets you surprisingly close to the truth. Employee count plus technology stack plus funding history plus office footprint paints a picture that is usually within a reasonable range of the actual revenue figure. You might not know if a company does $20 million or $30 million in revenue, but you can be fairly confident they are in that range rather than at $5 million or $100 million. And for sales qualification and deal sizing, that level of precision is usually sufficient. The companies that refuse to disclose revenue are not trying to hide from you. They just have no obligation to share it. The information to size them accurately is still out there. It just requires looking at different signals.
