Generic vs personalized — the difference

Generic opener

"I came across Notion and was impressed by the platform you've built."

OpeningLine opener

"Congrats on the Series C — expanding into enterprise after the SMB product finding PMF is the exact inflection point where the research workflow usually breaks down."

Generic opener

"Hi, I've been following Lemlist for a while and love what you're building."

OpeningLine opener

"Noticed Lemlist just posted 4 SDR roles in Austin — scaling outbound while the product is the outbound tool is an interesting problem to be inside."

Generic opener

"I came across your company and think what you're doing is really interesting."

OpeningLine opener

"The Salesloft acquisition of Drift changes the competitive dynamic for every PLG tool in the space — I imagine the conversation strategy is shifting pretty fast."

What signals it uses

Funding rounds

Signal: "Notion raises $275M Series C"

Uses the round size, timing, and stage to write an opener about what the capital is for and what pressure it creates.

Executive hires

Signal: "Stripe hires new VP of Revenue"

New executive = new agenda, new budget decisions. Reference the hire and what it signals about strategic direction.

Hiring surge

Signal: "Lemlist: 8 SDR roles open"

Rapid hiring is a buying signal — teams scaling fast have operational problems. The opener connects the hiring to the problem you solve.

Press coverage

Signal: "TechCrunch: Ramp reaches $100M ARR"

Recent coverage provides natural social proof to reference — shows you are paying attention, not just bulk-mailing.

Product launches

Signal: "Linear releases Projects feature"

New product launches often create new workflow problems. The opener frames your product as what comes next.

No signal found

Fallback: homepage positioning

When no live signal is found, falls back to their homepage description and writes a positioning-based opener instead of a generic one.
