Mammoth Biosciences

Paid once and never thought about it again. way faster than stalking LinkedIn all day.

grabbed the free climate list first, then upgraded. no sub to cancel, love that.

the CSV saved me a whole weekend tbh.

Emails didnt bounce. worth it on its own.

No login, no monthly bill, just the data. exactly what i needed.

solid US/UK coverage but my niche was thin, maybe a dozen that actually fit. the ones i got were correct tho.

was skeptical so tried the free 15. checked out, booked 3 calls that week.

Fewer names than the big dbs but every one actually invests. less noise.

spent 2 weeks guessing email patterns like an idiot. shouldve just started here.

dropped straight into my CRM, right columns and all. clean.

the AI search kinda got what i meant by seed climate leads. not perfect but quick.

2 of my first 10 bounced which annoyed me, verified should mean verified. support sorted it next day and the rest landed, but rocky start ngl.

79 bucks for the whole db forever vs 99/mo id forget to cancel. easy call.

Did what it said. the emails worked.

wanted phone numbers too but for cold email it nailed it. no account needed, rare these days.

datas good, search is a bit hit and miss. ended up filtering by sector and finishing in sheets. got there.
