Coverage matters more than features — what to ask any data vendor before you sign
Every B2B-data buying cycle eventually hits the same question: do you have my market? Here are the questions to ask before you sign — including the one most vendors quietly hope you skip.
The B2B-data sales conversation always starts with features. Sample fields, refresh cadence, API documentation, support SLA. By the time anyone asks "do you have my market?", you're three demos in and nobody wants to be the one to surface the awkward truth.
The truth is that a vendor's coverage map is more decision-relevant than their feature list. A flawless API with poor coverage in your sales territory is worse than a clunky API with great coverage. You can write around clunky APIs. You can't write around missing data.
The questions that matter
- Show me your coverage manifest. Real vendors publish a list of every market they cover, what status each market is in (live, beta, planned), and when the last refresh ran. Vague "nationwide" claims don't survive scrutiny — every nationwide vendor has uneven county-level coverage.
- What's the refresh SLA in my market? Not the marketing-site number. The number for the specific market you sell into. Some vendors refresh certain regions weekly and others quarterly — the headline cadence is the best market, not the average.
- What's the row count in my market today? If they can't tell you off the top of their head, the system probably doesn't track it well. Real vendors know how many active records they have in your top three sales geographies.
- Show me a sample export, in my filters. Not a generic sample. The data that would land in your pipeline if you signed today. If the sales team can't produce one, the data isn't ready to ship to you yet.
- What happens when I query a market you don't cover? This is the test most vendors fail. The right answer is a structured 404 that points you to the support flow so you can request priority coverage. The wrong answer is silently returning empty results — which means your team will spend a week debugging "no leads" before realizing they were querying outside coverage.
Why we built our coverage page the way we did
We publish /coverage as a first-class page, not buried in a help-center article. Every market is listed with its status (live / beta / coming soon), the freshness SLA, and the last sync timestamp. If a market isn't listed, we tell you it isn't there — and we route the request into a tracker so we can prioritize the markets customers ask for most.
We do this because we'd rather lose the deal than win it on a market we can't deliver. A customer who signs based on optimistic coverage claims churns within three months. A customer who signs knowing the exact shape of our coverage stays.
Two practical tactics
Run the coverage check on your top 10 sales geographies first. Not all markets, just the ten that drive 80% of your pipeline. If a vendor can deliver clean data on those, the long tail is a workable problem. If they can't, no amount of API quality fixes it.
Ask for the names of two customers in your industry, in your geography, and call them. Reference calls catch coverage gaps that demos miss. Demo data is curated. Production data isn't.
