Every channel in one workflow. A person on every reply.
HyperScale OS finds the right people, reaches them on LinkedIn, email, X and Instagram, and hands every real reply to your team.
Runs on the channels your buyers use
From a target list to a real conversation.
Start from your target list or let HyperScale suggest who fits, then keep the ones worth a message.
Dana, saw your team just opened the Reno site. How are you handling inbound scheduling across three docks?
Marcus, we work with a few plants on changeover planning and I'd value your view.
Nothing sensitive sends without a yes.
Put an approval step anywhere in a workflow. The message waits until someone approves it, and a rejection stops that prospect's workflow.
When someone answers, a person takes over.
A real reply ends the automation for that prospect. The conversation moves to the inbox with its history.

Pair it with the agent you choose.
HyperScale is an MCP server. Connect Claude, Codex or Cursor and ask it to run campaigns, work the reply queue or clear approvals. Or register a Grok agent, like our own Response Agent, to work the reply queue while a person approves what goes out.
[mcp_servers.hyperscale] url = "https://<your-workspace>/mcp" # then ask Codex: > pause the Q4 campaign and draft replies for everyone who answered today

Questions & answers
Does anything send without us?
Only what your workflow allows. Put an approval step anywhere and the message waits in Workflow Approvals until someone approves it. A rejection stops that prospect's workflow.
What happens when someone replies?
A real reply ends the automation for that prospect. The conversation moves to one inbox with its history, and the next message comes from your team.
How many DMs does it send?
Up to 45 Instagram DMs and 65 X DMs a day per account, below what the platforms technically allow. Volume grows by adding accounts, not by pushing one account harder.
Can a platform still restrict an account?
Yes. HyperScale sends as your logged-in account, so the real constraint is each platform's spam heuristics, not its published caps. No design can guarantee a platform will never restrict an account that automates outreach.
Which tools does it work with?
Instantly for cold email, Clean over MCP, LinkedIn and Slack today, plus any other MCP server you connect. HubSpot and Salesforce are listed as coming soon.
Is HyperScale OS open source?
It is a Nebula Labs project being released as open source. The source is not public yet; this page will link to it when it is.
