Run Every League
What Rostiro is
Rostiro is one dashboard for the fantasy football leagues you connect, across Sleeper and ESPN. Instead of opening a different app every Sunday to figure out what actually needs your attention, Rostiro watches them and tells you.
A founder's message
I'm building Rostiro by myself. The problem is a personal one: I'm in more fantasy leagues than I can comfortably keep straight, spread across more platforms than I want to open, and I got tired of the real skill of fantasy football quietly becoming "remember to open the right app before 1pm on Sunday." So I'm building the tool I actually wanted, in public, mistakes and all.
There's no big team or funding round behind this, just one person shipping. Free tier, Rostiro Pro at $9.99/mo, a 2026 Founder Season Pass, and a capped, one-time Founding 500 tier for the people who show up early. If you want to see how this actually gets built, week to week, the socials below are the honest version, not a highlight reel.
