My verdict: the reference for French B2B targeting.
Pharow offers targeting granularity (NAF codes, SIREN) that Apollo can't match on the French market. I'm not a fan of pre-built databases (I always prefer having control over the data), but it gets the job done. On the French market, it's better than Apollo for precise targeting. It's hyper granular for identifying niches.
What I like less: it's a pre-built database, so less control than custom scraping. It's limited to France only. And credit-based pricing can quickly become frustrating when you start scaling.
My advice: use Pharow if you target the French B2B market and want granularity (NAF codes, size, location). For international or if you prefer controlling your data, build your own lists with scraping.
