Move your dynasty league from Sleeper to League Tycoon
Sleeper is a popular all-purpose fantasy app that supports dynasty. League Tycoon is built specifically for dynasty leagues. If your league wants stronger dynasty-native features like slow auction drafts with 20+ simultaneous players, trade auctions, compensatory picks, and zero sportsbook clutter, switching is simpler than you think.
You do not have to rebuild your Sleeper league by hand
League Tycoon imports Sleeper leagues directly. Give it your Sleeper username or a link to the league. Sleeper's league data is public, so no password is involved. The import brings over your rosters, league settings and scoring, future draft picks, team logos, contracts where the source has them, and up to 20 seasons of league history. Past seasons come back as real seasons you can browse week by week, with standings, matchup lineups, playoff brackets, and final standings.
Sleeper history is followed automatically through the league's previous-season chain, so a league that has rolled over for years brings those years with it.
How league import worksWhy leagues switch from Sleeper
Slow auction drafts with 20+ players at once
Sleeper supports snake and linear drafts natively but doesn't offer true slow auction drafts with multiple simultaneous nominations. League Tycoon runs slow auctions with up to 20+ players on the block at the same time, complete with proxy bidding and anti-sniping timers.
Trade auctions
When a trade is posted on League Tycoon, any team can counter-bid on the players involved. It creates a transparent, market-driven process instead of backroom deals that half the league never sees. Sleeper doesn't offer anything like this.
Compensatory picks
Losing a star in free agency should come with compensation. League Tycoon handles compensatory pick logic automatically so commissioners don't have to track it in spreadsheets or rely on manual workarounds.
Draft lottery
League Tycoon has a built-in draft lottery system that discourages tanking and adds offseason excitement. No third-party tools or honor-system lotteries required.
Zero sportsbook clutter
Sleeper has increasingly leaned into sportsbook and pick'em features. If your league just wants a clean dynasty experience without betting prompts, League Tycoon keeps the focus entirely on your league.
League history and Hall of Fame
Every league has a story. League Tycoon's Hall of Fame stores all-time standings, trophies, head-to-head records, and high scores. Your league's legacy is front and center, not buried in a settings menu.
What you gain on League Tycoon
League Tycoon is a dynasty-first platform. Every feature is designed for leagues that play year after year. Here's what your league gets on day one:
- •A built-in import that brings your rosters, picks, settings, and past seasons across

Step-by-step migration guide
The import does the heavy lifting, so the commissioner's job is mostly reviewing and inviting.
1. Run the import
In League Tycoon, open Tools, choose Import League, pick Sleeper, and enter your Sleeper username or paste a link to the league. Choose standard dynasty (free) or contract dynasty (paid), and choose how many past seasons to bring over.
2. Review the preview before anything is created
You see every team, roster counts, how many players matched, a summary of the scoring and roster settings being mapped, and anything that will not carry over. Nothing exists until you approve it.
3. Work the post-import checklist
Your league opens with a short list of items worth a human decision: any players that could not be matched, scoring rules to confirm, playoff and waiver settings to review. Each item deep links to the screen that resolves it.
4. Confirm the details the import cannot know
Trade deadlines, taxi and IR rules, and anything your league runs by convention rather than by setting. If you're running contract dynasty, review the contract structure and cap rules.
5. Invite your league mates
Share the league invite link in your group chat. Each league mate claims their own team from a list, so you're not assigning twelve people by hand. They see their own roster and their own team logo immediately.
6. Run your first draft or start the season
Set up your next draft (try a slow auction if you haven't before) or jump straight into the season. You're live on League Tycoon, with your league's history already in place.
What about contract dynasty?
If your league wants salary caps, multi-year contracts, franchise tags, and dead money, League Tycoon offers a full contract dynasty experience. It's the most advanced contract system available on any fantasy platform.
Contract dynasty is a paid feature, but standard dynasty is completely free. Your league can start with standard dynasty and upgrade to contracts later if you want to add that layer of strategy.
Convincing your league mates
The easiest way to get buy-in is to share the app and let people explore on their own. Most league mates care about two things: "Is it easy to use?" and "What do I gain?" League Tycoon answers both quickly.
A few tips that work:
- •Send the league invite link and let people poke around before committing
- •Highlight the specific features your league has been wanting (slow auctions, trade auctions, etc.)
- •Make the switch during the offseason when there's no time pressure
- •Share the FAQ for skeptical league mates to address common concerns upfront
