SecondStack gives an entire organization access to AI without handing its data to third-party clouds.

The platform ships three end-user workspaces โ€” Chat for everyday work, Code for engineering teams, and Agent for automation โ€” running on top of an enterprise LLM gateway that connects to the model providers you choose (OpenAI, Anthropic, Google, and others). Platform and security teams manage everything centrally: who can use which models, what each team spends, and where data lives โ€” inside your own infrastructure.

Because SecondStack is self-hosted, prompts, files, and knowledge bases never leave your environment. For teams that prefer not to operate it themselves, a managed deployment run by the SecondStack team is also available.

Pricing is not per-seat, so rolling AI out to the whole company does not multiply the bill. Deployment and operations are backed by an ISO 27001-certified implementation partner.

The 6 Best Calendly Alternatives in 2022 (Free & Paid Options)
Note: much the same as with Salesloft, it can be tempting to use Outreachโ€™s calendar functionality if youโ€™re already on the platform, but bear in mind that as a secondary feature built on top of the platform, it lacks the complexity needed for advanced teams.

  • Solving the argument between Calling vs Email outreach
    Theres tons of tools to make the email personalizing faster. I.e lavender autobound.ai etc. And sequences like outreach.io / salesloft. Source: about 3 years ago
  • Advice
    A solid playbook for automating emails is using a sequencing tool like outreach.io and email writer like autobound.ai. Outreach manages the sending/replying/organizing and Autobound manages the actual content of the emails. Theres other products out there for this as well, these are just two that come to mind.

    Using outreach.io? Then free trial https://www.orum.com/ and power dial your way to call heaven. Source: over 3 years ago
