Frequently asked questions

How big is the B2B data market?

Grand View Research puts revenue in the global B2B data marketplace segment at $863.2 million in 2024 and forecasts $3,215.7 million by 2030, growth of 24.6% a year. That covers data marketplaces only, not the full sales intelligence software market.

Which B2B contact database is the largest?

By the vendors' own counts, People Data Labs lists 1.5 billion person profiles, ZoomInfo more than 500 million contacts and 100 million companies, and Apollo more than 240 million contacts and 30 million companies. TAM Graph holds more than 60 million companies and 408 million people. The counts are not measured the same way, so they are not directly comparable.

How accurate is B2B data?

In a Harvard Business Review study, 47% of newly created records had at least one critical error, and only 3% of the quality scores were acceptable. In surveys, CMOs estimate 45% of their marketing data is incomplete, inaccurate or outdated, and data and analytics leaders estimate 26% of their organization's data is untrustworthy. Vendors claim much higher figures for their own data, such as Apollo's 98% email accuracy rate.

What does bad B2B data cost?

Thomas Redman, writing in MIT Sloan Management Review, estimates the cost at 15% to 25% of revenue for most companies. In Monte Carlo's 2023 survey, data professionals said data quality issues affected 31% of revenue on average. Salesforce finds that sales reps spend 60% of their time on non-selling tasks.

How complete are B2B company records?

In a random sample of 10,000 records from People Data Labs' free company dataset, 27.2% had no website and 63.2% had no founding year, while 93.7% had a LinkedIn company URL. 69.8% of the records were companies with 1 to 10 employees.

Method

We searched Google for b2b data statistics, b2b contact data statistics and b2b data quality statistics, read the pages that ranked, and counted how many of them repeat each number. Each outside number was traced to the company or survey that produced it and checked against that page on September 24, 2026. Database sizes and accuracy rates are the vendors' own claims about their products; we found no independent audit that compares them. Most quality figures come from surveys by data and software vendors (Adverity, Precisely, Monte Carlo, dbt Labs, Salesforce), so they measure what respondents believe about their data, not the data itself. The Harvard Business Review study is the one direct measurement of record errors we found; we found no peer-reviewed paper that measures B2B contact data accuracy. Numbers on data decay are on our separate B2B data decay page and are not repeated here. TAM Graph's numbers are field fill rates in random samples of 10,000 records drawn from its database on September 24, 2026.

TAM Graph numbers new on this page:

  • 69.8% of company records in People Data Labs' free company dataset are companies with 1 to 10 employees, and 17.7% have 11 to 50. MongoDB $sample over TAM Graph's copy of the People Data Labs free company dataset; share by the size field.
  • 27.2% of company records in People Data Labs' free company dataset have no website, and 63.2% have no founding year. Same sample. Missing = field absent, empty or a placeholder such as None or unknown.
  • 93.7% of company records in People Data Labs' free company dataset carry a LinkedIn company URL, more than carry a website (72.8%), in TAM Graph's September 2026 check. Same sample, share with a non-empty linkedin_url and website field.
  • In a random sample of 10,000 person records in TAM Graph, 95.6% have a job title but only 6.7% have a seniority level. MongoDB $sample over TAM Graph's largest person collection; share with a non-empty title and job_level field. A title can still be turned into a seniority level by parsing it.
