Monitrees

We re building Monitrees, a monitoring tool that focuses not only on servers, but also on business platforms where revenue actually happens.
Right now, we monitor:
Ad platforms (Meta / Google Ads): account restrictions, ad disapproval, campaign shutdowns
Payment platforms (PayPal / Stripe): account issues, disputes/chargebacks, balance or payout problems
E-commerce platforms (Shopify / etc.): product delisting, inventory errors, store status anomalies
But we want to go deeper and that s where your experience matters.
Questions for you:
Which failures hurt your revenue the most: ads being paused, payments disputed, or products going offline?
Have you ever noticed an issue too late only after sales dropped or customers complained?
For ads: is your biggest pain budget burn, ROAS drop, banned account, or something else?
For payments: disputes (chargebacks), account freeze, delay in payouts, fraud which matters most?
For e-commerce: inventory sync issues, product out-of-stock, hidden delisting, API errors what s your nightmare scenario?
Why I m asking:
We want Monitrees to help founders and operators detect business-critical anomalies early not just CPU spikes. Before money is lost. Before ads stop running. Before products disappear from the store.
Would love your thoughts, experiences, or even horror stories it ll help us build the right thing.
