My agent did an analysis:

On Nov 12 I tested LeadOcean on our top 100 people (including the 42 we already had Apollo emails for) and on 20 companies.

**Accurate (companies):**
- Name, domain and industry matched on all 20.
- Headcount was within 25% for 17 of 20. The outliers were Bitpanda, Berner Kantonalbank and Acelity.
- HQ country was right for 18 of 20. Bitpanda came back as Romania instead of Austria, and Lancashire as the US instead of Bermuda.
- Founded year was right every time Apify also had it, and LeadOcean filled 4 that Apify was missing.
- It also gave the tech stack for 19 of 20 and real funding data for 11, which Apify doesn't have.

**Partly accurate (people):**
- It found 80 of the 100 people. The misses were free, and they included CISOs at ING, Robinhood and Bitpanda.
- The current title was right for about 78% of the ones it found.
- The current company was right for only about 59%. That rises to 73% if you count jobs from their history.
- It always returned the right LinkedIn profile, with no wrong-person swaps.
- It had a phone number for 55 people, which Apollo never gave us.

**Not accurate (emails):**
- 79 people came back with some email, but only 12 were verified and just 8 were verified work emails.
- Of its best emails, 33 were catch-all, 25 untested and 7 invalid.
- On the 42 people where we know the right Apollo email, LeadOcean had it only 40% of the time.
- Most of the misses were emails at people's old employers. For example, the InvestCloud CISO came back with a PwC address and the Domino CISO with a Bloomreach one.

The bottom line is to use LeadOcean for company data and phone numbers but not for emails. I'd only trust one of its emails when the person's current company matches LinkedIn, the email is on that company's domain, and it isn't marked invalid. Otherwise, Apollo is the source.
