I tested LeadOcean for prospecting small, owner-run trade businesses, checking it against a list where I already knew the answers.

What worked
- Counts and breakdowns are free, which makes sizing a market quick.
- The Claude connection works well. I could search and enrich without exporting CSVs.
- Staff size was a useful second source when I had nothing else.
- No hard monthly record cap on my plan, just fair use.

Where it fell short for me
- Coverage of very small local businesses is thin. It found about half of the company websites I looked up.
- Tech detection missed most of the software I’d already confirmed these businesses use.
- Keyword search pulled in unrelated companies, so results needed cleaning.
- Very few of these businesses had an email contact, so it couldn’t power a cold email campaign in this niche.

Bottom line: If you sell to companies with a real web footprint, it’s probably a good deal. If your market is 1 to 15 person local service businesses, expect to lean on Google listings and state records, with LeadOcean as a supplement. I’ll update this if I get better results in other markets.
