Adapt.io vs The Data City: A Comparison That Shouldn't Exist
Here's the thing: Adapt.io and The Data City aren't competitors. They're not even in the same product category. Comparing them is like comparing Salesforce to a Bloomberg Terminal - both involve "data," but that's where the overlap ends. We see this confusion a lot, and it tells you something about how messy the B2B data space has become.
30-Second Verdict
Adapt.io is a B2B contact database for finding emails and phone numbers. The Data City is a UK industry classification platform for mapping emerging sectors and replacing outdated SIC codes.
Need to classify and analyze UK industries beyond SIC codes? The Data City is your tool.
What Is Adapt.io?
Adapt.io is a B2B contact database built for sales teams who need emails, phone numbers, and company data at scale. The database covers 250M+ contacts, 16M+ decision makers, and 12M+ company profiles, with 5M+ data points refreshed daily. Sources include SEC/Edgar filings, SMTP validation, web crawling, and crowdsourced contributions.
Plans start at $49/mo for 500 email credits plus 500 enrichment credits, with a free tier offering 25 of each. Annual billing drops costs roughly 20%.
Use this if: You're an SDR or small sales team that needs a self-serve contact database without a five-figure annual contract.
Watch out for: Phone credits don't kick in until the $99/mo Basic plan, which only includes 100 phone credits per month. Teams running heavy outbound will burn through those fast.
What Is The Data City?
Founded in 2017, The Data City is a UK-focused industry classification platform covering 9M+ UK companies across 400+ Real Time Industrial Classifications (RTICs) with 90+ datapoints per company. Instead of relying on the SIC code a company chose at registration - often years ago, often wrong - it classifies companies based on what they actually say they do on the web. RTICs cover sectors like AdTech (374 companies) and Advanced Manufacturing (10,039 companies), a level of granularity SIC codes simply can't match.
The methodology is peer-reviewed and used by national statistics agencies. Oxford Economics invested £2M at a £19M valuation, which tells you the kind of buyer this product serves: policymakers, economic researchers, and investors.
Use this if: You're a researcher, policymaker, or investor who needs real-time UK industry mapping beyond broken SIC codes.
Skip this if: You need contact data for sales outreach. The Data City doesn't provide emails, phone numbers, or anything an SDR would use.
If you're here comparing sales data tools, you need verified contacts - not industry classifications. Prospeo gives you 300M+ profiles, 98% email accuracy, and a 7-day refresh cycle at ~$0.01 per email. No annual contracts, no five-figure commitments.
Get better data than Adapt.io at a fraction of the cost.

These products serve different buyers solving different problems. An SDR would get zero value from The Data City. A policy researcher would get zero value from Adapt.io. Neither tool has a major review-site footprint on G2 or Capterra, which itself reflects how niche each one is.
