Apollo.io
A searchable database of 275M+ business contacts plus the outreach tools to email and call them - prospecting in one tab.
Who it's for
Any business that sells to other businesses and has no repeatable way to find new customers beyond referrals and hope.
Our take
If your growth plan is “wait for word of mouth,” Apollo replaces it with a system: filter for exactly who buys from you (industry, size, role, location), get verified emails, and run follow-up sequences that don’t forget. B2B businesses live and die on pipeline - this builds one.
The honest downside
Cold outreach is a skill, and consent rules differ by country (especially in Europe) - start with tight lists, real personalization, and your local rules checked.
What it costs
Genuinely useful free tier; paid from ~$49/user/month.
