The operating system for fantasy sports

You didn't lose because you made a bad call. You lost because the alert was in a different app. Rostiro watches the leagues you connect and tells you the one thing to do before it costs you.

ILLUSTRATION · SAMPLE DECISIONS

STANDARD

Good morning. 5 decisions across 3 leagues.

Estimated time to clear: 2 minutes.

CRITICAL

Bench Stefon Diggs in 2 leagues. 31 mph winds in Buffalo at kickoff.

IMPORTANT

Claim Jaylen Warren in League 2. Waiver cutoff is 3:00 PM today.

REVIEW

Trade pending: your Kupp for their Ekeler. Lean accept, it fixes your RB2 gap.

WATCH

Joe Mixon is questionable. Pivot option ready: Zach Moss.

You're not bad at fantasy. You're just checking the wrong app.

A bench player takes a season-ending hit. ESPN has it. You find out Monday.

A waiver window closes at 3pm in your ESPN league. You had Sleeper open.

Three of your rosters are all in on the same running back, and nobody warned you.

Rostiro watches all of it, so you don't have to remember to.

One card. Every league. What actually matters.

Rostiro States

Rostiro doesn't look the same on a random Tuesday as it does at kickoff.

The whole product reprioritizes itself around what your leagues actually need right now: five states, driven by the calendar, not a setting you have to manage.

Rostiro Pulse

One list. Every league. What actually matters today.

Every morning, Rostiro checks your rosters across ESPN and Sleeper, then hands you a short, ranked list of what to do and why. Tap a decision and it takes you straight to the fix. No dashboards to dig through, no tabs to remember.

Built around how you actually play.

Pick a mode once. It reshapes the entire product around you, not the other way around.

Focused

“Tell me what to do.”

Five decisions, max. The verdict first, reasoning if you want it. Built for the 90-second check between meetings.

Balanced

“Show me the key stuff.”

The call, plus the context that made it: matchup, injury, weather. Tap anything to go deeper.

Savant

“Give me everything.”

The full data layer. Target share, usage trends, Vegas lines. Rostiro advises, you decide.

Works with the leagues you're already in

ESPNSleeper

Connect a league in under a minute. No new accounts for you, no new apps for your leaguemates.

Know which league needs you first

Every league gets a Health Score, so you open the app knowing where the risk is, not just reacting to it.

One tap to the right platform

Rostiro tells you exactly what to do, then deep-links you to the exact right screen on ESPN or Sleeper to make the move. Read-only, on purpose, so your leagues stay exactly where they are.

See your risk before it becomes a problem

Rostiro flags when you are overexposed to one player across your leagues, before a single injury wrecks your week.
