Sistava is an AI workforce platform where solo founders hire AI employees to run their business around the clock. Each AI employee has a specific role (sales, marketing, customer support, operations), real tool integrations, persistent memory, and works inside your existing apps like Slack, Gmail, and HubSpot.

What is an AI employee?

An AI employee is an autonomous AI agent with a defined role, persona, skill set, and tool access. Unlike an AI chatbot that only responds to questions, an AI employee takes on recurring tasks — writing emails, qualifying leads, answering support tickets, publishing content — and works independently 24 hours a day without being prompted each time.

How is Sistava different from project management software?

Sistava is not project management software. It is an AI workforce platform — you hire AI employees who do the work, not software that helps you track work done by humans. AI employees on Sistava autonomously run sales outreach, write marketing content, answer customer support tickets, and handle operations tasks without human micromanagement.

How much does Sistava cost?

Sistava plans start at $19 per month. All plans include unlimited AI employees, real tool integrations, and 24/7 autonomous work. A free trial is available with no credit card required to explore the platform.

What can AI employees do on Sistava?

AI employees on Sistava can handle sales (lead qualification, outreach, pipeline management), marketing (content creation, ad campaigns, SEO), customer support (ticket responses, live chat), operations (workflow automation, logistics coordination), recruiting (candidate sourcing, screening), finance, and more. Each role comes pre-trained and ready to start work immediately.

Sistava is built for solo founders and small teams who need to run sales, marketing, support, and operations without hiring a full human team. It gives founders the equivalent of a full growth team — SDRs, marketers, support agents, and ops specialists — starting from $19/month.
