50k → 100k LinkedIn followers · 40k → 60k on X
Where it started
My first full-time job after college and my first recurring founder-content programme. Accounts: Karthik, another co-founder and the Buildd brand page. Karthik had about 50k followers and good ideas, but the posts lacked context and situations readers recognised.
What I did
Social media manager. Founder content across three accounts.
- Kept about 75% of the mix for structured insights and 25% for corporate jokes, appreciation posts and founder breakdowns.
- Wrote each post around a specific person, problem and point of view.
- Wrote tweets and threads and worked on collaborations.
What changed
- Founder-led content reached 5M+ monthly organic impressions.
- Inbound calls rose from 1–2 a day to 60–70 a day at peak.
- The Buildd page passed 15k+ followers. The other co-founder’s page grew at a similar rate.
