The question isn't what to personalise. It's where the intersection is between what you sell and what your prospect deals with every day. Everything else is noise.
“Congrats on the funding round.” “I saw you went to Manchester.” “Love what you’re doing at [Company].” Every tool scrapes the same data and produces the same email. Your prospect has seen it 30 times this week.
You’ve just raised, which means you’ve probably spent months pitching investors instead of pitching hospitals. Now the money’s in, you need to fill a pipeline. That’s reading between the lines. That’s what gets replies.
ReplyLabs gives you visibility and control over the data you’re working with. Scrape it, see it, understand it, then use it intelligently. Not a black box that spits out an opener you can’t explain.
No new platform to learn. No data migration. No onboarding video. It sits in the sidebar of the spreadsheet your team already works in. That’s it.
Clay and Apollo are powerful. But they cost $50–500/user/month and don't live where your data already is.
