Best AI for cold outreach research that pulls beyond what's already on LinkedIn?
I'm doing outbound for a B2B client and every "AI personalization" tool I've tried is basically pulling the same five LinkedIn data points and rewriting the first line of the email around them.
Things I care about:
Pulls real signal from blog posts, podcast appearances, conference talks
Finds recent content the prospect actually engaged with publicly
Doesn't pattern-match to a template I've seen 50 times this month
Handles 20-50 prospects per batch without breaking
Plays nicely with Apollo or Instantly
Outputs go in a CSV I can edit, not locked in their UI
I've tested Clay (powerful but feels like I'm building a custom pipeline every time) and Lavender (good for tone but the research depth is shallow). The personalization in both still ends up at the "I noticed you recently moved to Series B" level when I actually need "I noticed you said on the X podcast that retention is your top priority for 2026."
Which tool actually surfaces signal someone would only know if they'd done real research?
