Rewrite your LinkedIn About section so it reads as a person, not a resume

Here's what I have now, or rough notes about myself: I have 8 years in B2B marketing. I led demand gen at two startups. I like data-driven growth and building teams..
My role and what I actually focus on: Head of Growth at a seed-stage fintech, focused on organic and lifecycle.
Words or phrases people would search to find someone like me: demand generation, B2B SaaS, lifecycle marketing, fintech.
Who's likely to read this (recruiters, clients, peers): Recruiters sourcing growth leads, and founders considering hiring me.

Rewrite this as a LinkedIn About section, first person, under 2,600 characters (LinkedIn's field limit). Rules:
1. The first 2-3 sentences must work as a complete, compelling summary on their own — LinkedIn shows only roughly the first 300 characters before "...see more," on both the profile and in search results, so don't front-load context that only pays off later.
2. Write like the person is talking, not like a resume summarizing them in third person — no "Jane is a results-driven professional with 10 years of experience."
3. Work in the keywords from demand generation, B2B SaaS, lifecycle marketing, fintech naturally, inside real sentences — not as a bolted-on list of skills at the end.
4. Include one or two specifics (a real number, a real project type, a real turning point) instead of only abstractions like "passionate" or "dedicated."
5. End with one plain sentence saying what you want the reader to do — connect, reach out, view your portfolio — not left implicit.

After the rewrite, give me the character count and confirm it's under 2,600.
