LinkedVelocity vs SBL.so
SBL.so is an outreach-as-a-service platform that recruits real LinkedIn users to run campaigns on your behalf. LinkedVelocity rents you the account directly so you control the messaging, tools, and targeting yourself. Both use real accounts — the difference is who's driving.
Control vs convenience. LinkedVelocity gives you direct access to LinkedIn accounts — you run your own campaigns with your own tools. SBL.so manages the outreach for you via AI and the account owner. LinkedVelocity is cheaper (from $10/mo, no platform fee) and gives full control. SBL is more hands-off but costs more and limits your customisation.

When to choose LinkedVelocity
Choose LinkedVelocity when your team already knows how to run LinkedIn outreach and just needs more accounts. You get direct browser access via GoLogin, use your preferred automation tools, write your own messages, and iterate on campaigns in real-time. No middleman, no AI writing messages you haven't approved, and no platform fee on top of the account rental.
When to choose SBL.so
Choose SBL when you want LinkedIn outreach fully managed. You provide a campaign brief, SBL's AI handles the messaging, and the account owner executes from their own device. This works for teams without outreach expertise or those who want zero operational overhead — but you sacrifice control over messaging, targeting adjustments, and tool choice.
The control trade-off
SBL's AI handles 95-99% of conversations automatically. That's convenient, but it means you don't control what gets said to your prospects. If your outreach requires nuanced, personalised messaging — or if you've invested in your own sequences and templates — LinkedVelocity lets you run exactly the campaigns you've built, on additional accounts, with no AI filter between you and the prospect.
Cost comparison
For 5 LinkedIn accounts, LinkedVelocity costs $50-250/month total (just account rentals, no platform fee). SBL costs $175-250/month in profile fees plus a $99-189/month platform fee — $274-439/month total. LinkedVelocity is 40-60% cheaper at the same scale, and you can use any automation tool you already pay for.
FAQs
What's the difference between renting an account and a fractional SDR?
When you rent a LinkedIn account on LinkedVelocity, you get a browser session and full control — you write the messages, pick the targets, and run your automation tools. With SBL.so, the account owner runs the outreach on your behalf using SBL's AI platform. You provide the campaign brief, and they execute. It's the difference between renting a car and hiring a driver.
Which is cheaper?
LinkedVelocity is cheaper per account. A basic LinkedVelocity rental starts at $10/month with no platform fee. SBL.so charges $35+/month per profile plus a $99-189/month platform fee. For a 5-account setup, LinkedVelocity could cost as little as $50-250/month total, while SBL would cost $275-364/month minimum.
Which gives me more control over messaging?
LinkedVelocity. You have full access to the browser session, so you write every message, customise every connection request, and adjust campaigns in real-time. With SBL.so, an AI handles 95-99% of conversations — you set the brief, but you don't control individual messages.
Is SBL.so safer because the owner runs outreach from their own device?
SBL's model avoids anti-detect browsers by having the account owner use their own device, which is a legitimate safety advantage. However, LinkedVelocity's GoLogin approach with residential proxies also achieves a 0% restriction rate. Both models work — the question is whether you want control (LinkedVelocity) or hands-off managed outreach (SBL).
Can I switch from SBL.so to LinkedVelocity?
Yes. If you've been using SBL and want more control over messaging, targeting, or automation tools, LinkedVelocity gives you direct account access. You can use any automation tool you prefer, write your own messages, and adjust campaigns without waiting for a third party.
