Is it okay to send this referral request on LinkedIn instead of email?

Yes if this CTO is actually active there and the thread isn't about long attachments. Keep the LinkedIn version even shorter. Don't paste the full email. One context line and one question is plenty. Name the stall they care about, offer one small next step, and stop before the thread feels like a sequence.

What should I never say in a Pharmaceuticals referral request?

Can I use aggressive sales language in pharma outreach?

No. Unapproved claims, off-label hints, and fake urgency can create real problems. Be operational: timelines, review status, access, meeting logistics.

How should a referral request to a Pharmaceuticals CTO change for after an invoice?

Neutral and factual. Warmth without jokes. Don't invent clinical claims. Don't treat HCPs like a funnel. If you don't know the rules, your email is a liability. The CTO is guarding reliability, security, and engineering time, so the ask should stay at "a technical working session or a written teardown, not a 'vision call'." If you copy a generic template
