Auto-find groups, lock on in bulk

You don’t need to know where the groups are — type an industry keyword like “dental care” and CAS auto-collects public group invite links page by page, listing target groups for you to tick.

Distribute group joins across multiple accounts

One account joining aggressively draws attention. Multiple instances join together with automatically staggered pacing and auto-stop on anomalies — fast, and steady.

Members in the library in 5 seconds

Joining is just the start — member phone numbers land in your library in 5 seconds (100 members per group), deduped by phone and straight into your reachable Lead base.

FAQ

Where do the groups come from?

CAS auto-collects invite links of public groups page by page based on your industry keyword — only publicly joinable groups — and lists them for you to choose.

Will joining too fast get accounts limited?

It stays under the radar — chosen groups are shared across multiple instances with staggered pacing, and everything auto-stops on anomalies instead of pushing through.

How do group members become customers?

Member phone numbers land in the library in 5 seconds (100 per group), are deduped by phone and enter the Lead library — tag, follow up and reach out directly.

Can it join private groups?

No. CAS only handles public group invite links and never touches private groups — that’s the product boundary and the baseline of account safety.
