Founder Letters
Fortnightly letters from a founder in the building.
Not a newsletter. Not a growth hack. Just honest writing from someone building CofounderUp — what I'm learning, what I'm struggling with, and why I think cofounder compatibility is the most underrated problem in the Indian startup ecosystem.
What to expect
- One letter every two weeks
- Written personally by Partha — not AI, not a team
- No sponsorships, no ads, no hidden agenda
- Focused on founders, cofounders, and early-stage building
- You can unsubscribe anytime, no questions asked
Who it's for
If you're thinking about starting something. If you're building something quietly. If you've been searching for a cofounder and can't find the right one. If you're just trying to understand what it actually takes.
