If the SaaS target customers are smaller companies / startups, then this may be viable
I'd love to hear more about your idea though! would you mind sharing a little bit about it?
The idea is a simple marketing tool to help businesses reach out to customers that didn’t convert fully through the funnel. So for example, user created a profile, but didn’t end up purchasing.
If interested, I can share the link (once it’s up) and would love to get your feedback.
I’m your target audience.
The #1 issue I have with this concept is, as a customer, I would have to trust that you understand the performance limits of my production database and that you won’t run (even accidentally) a burst of inefficient queries that takes down or impairs production.
One way around this would be to query against a replica / secondary, but even then you risk overloading a secondary/replica, which could have negative effects in a failover scenario.
Option 1 seems like a lot of work for the customer ... probably not viable.
Option 2: you can securely connect to their data-source using oAuth2.0. In fact I know MongoDB offers this (https://www.mongodb.com/docs/atlas/security-oidc/) for this exact use-case I believe. I recall using Vercel to integrate with my MongoDB.

Though I haven't done it directly, I think integrating with the DB through a secure protocol like oAuth is the way to go. DB services offer this and must be for this exact use case.
