I’ve been building a sports betting analytics app called THE LINEUP, and the whole idea is pretty simple:

Instead of guessing who wins, it looks for +EV bets by comparing sportsbook odds against fair odds.

So if a sportsbook is offering a price that looks better than the fair number, the app flags it. The goal is to treat betting less like “I like this team tonight” and more like finding small mispriced opportunities.

Example from today’s board:

Nolan McLean under 17.5 outs recorded was showing +6.2% EV at Novig when the board refreshed.

That obviously does not mean it is guaranteed to win. Any single bet can lose. But the side hustle thesis is that if someone is disciplined, shops lines, sizes bets properly, and only takes +EV spots, they may have a better chance of making sports betting profitable over time than just tailing picks or betting opinions.

I’m curious how this community sees it.

Would you consider +EV sports betting a legitimate side hustle if the process is systematic and bankroll-managed, or is the variance/risk too high for most people?

I’m also looking for blunt feedback on the app/positioning :)

I’m building THE LINEUP, a sports betting analytics app that helps users find +EV bets, compare odds across books, and track whether the edge was actually executable.

The original version was way too “dashboard-first.” Lots of tables, numbers, grades, and filters. Useful if you already understood EV betting, but probably overwhelming if you didn’t.

What I’m learning now is that the harder product problem isn’t just finding edges. It’s making the edge feel trustworthy:

Where did the fair price come from?
How fresh is the line?
Has the number already moved?
Is this an EV+ market signal or a projection model signal?
Would a real bettor actually be able to place this?

So I’ve been rebuilding the product around clearer explanations, fresher odds snapshots, and less “trust me bro” pick presentation.

Would love feedback from other builders on two things:

For a data-heavy product, how much methodology do you show before it becomes clutter?
If you were evaluating a betting analytics tool, what would make you trust or distrust it fastest?

The app is paid, but I’m happy to give free trials to people who want to poke around and give honest product feedback: https://thelineup.pro

Could +EV sports betting be a real side hustle if you treat it like arbitrage instead of gambling?
