What Promonyx is, and what it is not
A short page, because there is not much to hide behind. This is a calculation tool for sportsbook sign-up offers, run by one person, and it charges for the thing it does rather than for the thing the sportsbooks do.
What it is
Promonyx reads publicly advertised sportsbook sign-up promotions, works out what each one is actually worth once the odds on both sides are accounted for, and shows you the exact second bet that covers it. The arithmetic is the product.
What it is not
Not a sportsbook. It never accepts a wager, holds a balance, or places a bet for you — every bet is placed by you, in your own account, under that book's terms. Not a tipster either: nothing here predicts who wins, because the whole method is built to stop that from mattering.
How it makes money
You unlock promotions one at a time, and the fee is a fixed share of what that promotion is estimated to be worth, set when you pay and never recalculated. There is no subscription, and no percentage of anything you make. Your first promotion is free so you can see it work before paying.
Who runs it
SJR Betting Basics LLC, a one-person company. Support, refunds and the answer to any awkward question all come from the same inbox, which is a deliberate choice and not a temporary one.
The things a page like this usually leaves out
You can lose money doing this
Prices move between the moment a figure is calculated and the moment you place. Books void bets, apply terms inconsistently, and limit accounts. A promotion that was described correctly can still settle against you.
Sportsbooks may limit you for it
Accounts that only ever appear for promotions get noticed, and the usual response is quietly reduced maximum stakes. It is the real long-term cost of doing this and it is better known before you start.
There are no customer testimonials here
There is a reviews page and it is empty, because every review has to come from a signed-in account and be approved by a person. It will stay empty rather than be filled with invented ones.
The offers run out
Sign-up bonuses are one per person per book. The early money is the best money, and the pace slows once the major books in your state are done. Anyone telling you otherwise is selling something.
