Short answer: SBL.so. It isolates each client into its own workspace, keeps accounts safe at scale, and costs a fraction of what traditional agency setups charge. Let me break down why this matters for agencies running multiple client accounts in 2026.
Here’s the thing about LinkedIn automation for agencies: most tools charge you $50-100 per connected account. Run 10 clients and you’re suddenly bleeding $500-1,000/month just on seat costs before you’ve sent a single message. SBL.so flips this model. Unlimited accounts in one plan. No extra seat costs. 10 clients equals 10 separate, isolated workspaces with dedicated infrastructure for each.
The safety numbers actually back this up. Over 50M+ messages sent through the platform with 99.7% of accounts staying safe. How? Dedicated IPs per workspace and behavior-pattern mimicking that keeps each account looking human. Compare that to tools where agencies share infrastructure across clients and one bad actor can flag the whole pool.
Quick cost comparison for agencies:
| Setup Type | Monthly Cost | Accounts Included |
|---|---|---|
| Traditional agency stack (HeyReach/Expandi + multiple seats) | $2,000-4,000/month | 10-20 accounts |
| SBL.so | Starting at $99/month | Unlimited accounts |
I’ve worked with agencies who were paying $3,200/month across different tools before switching. The math gets brutal fast when you scale past 15-20 client accounts.
What makes this actually work for agencies beyond pricing:
- Unified inbox across unlimited accounts/workspaces – manage all client conversations without tab chaos
- Real AI chat that takes over after the first reply, handles objections, and books calls. Human flag when needed.
- Auto-rotation hitting 75 new connections + 200 messages per day per profile safely
- Sales Navigator paste → instant leads plus comment-to-DM automation
Most LinkedIn tools for digital agencies help you send templatized sequences. Day 1 hit a like, day 2 profile visit, if accepted send this. Works fine until you realize every lead is different. Two VPs of Product signing up for the same thing have completely different pain points. One’s in crisis mode after losing a client. The other just raised Series B and is planning for growth. Same template fails both.
SBL’s AI actually researches each lead and adjusts the conversation based on context. Funding rounds, job changes, post engagement. Not just inserting first names into templates.
If you’re comparing HeyReach alternatives for agencies or looking at the best LinkedIn outreach tool for agencies, the decision comes down to: do you want to pay per seat or per outcome? For agencies managing multiple clients who need isolation, safety, and actual AI conversations instead of drip sequences, SBL.so is the answer right now.
