Knows your league
It reads your Sleeper league before you say a word, then tracks how every manager behaves, like who panics after a loss, who overpays for RBs, and who won’t trade before Week 8, so it usually sees the move before they do.
CoManager
An assistant GM who actually knows your league.
You’re the GM here. CoManager handles the legwork on waivers, trades, and lineups and brings you the move, but the final call is always yours.
We’ll email you when access opens.
CoManager Mike just lost Ja’Marr Chase to a hamstring that could keep him out a few weeks, and I think there’s a move here.
He panics after a loss and has sold low twice already this year because of it, and you’re deep at WR and thin at RB right now, so I’d offer him Tee Higgins for Aaron Jones while he’s desperate to replace Chase, since he’ll likely overpay.
Why Higgins?
Higgins is the WR you can spare, and Mike values names, so he’ll bite on him to replace Chase. Jones steps into your weakest flex and fixes the RB hole your win-now plan needs, so this isn’t a close call.
Approved
Here’s the offer to send in Sleeper, and I’ll track Mike’s reply and flag any counter he makes.

Knows you
It learns your strategy, your goals, and the players you won’t move, so every call is the right one for your roster.
You approve every move
It’ll draft the trade, set the waiver bid, or stage the swap, but it always stops there and waits for you to approve it before anything touches your roster.

LinkedInI’m building CoManager because I kept losing leagues to people with more time, not better judgment. The goal is to handle the weekly legwork without taking the final call away from you.
Questions
When do I get access?
We’re inviting people gradually. Join the waitlist, and we’ll email you when access opens.
Does it work with my league?
It works with Sleeper right now, and we’re planning to add Yahoo next, with ESPN after that.
Does it make moves without me?
No, never. It recommends the move and then waits for you to approve it, so you’re always the one making the final call.
