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 like sales, marketing, or customer support, with real tool integrations, persistent memory, and the ability to work 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 a chatbot that only answers questions, an AI employee takes on recurring work like writing emails, qualifying leads, answering support tickets, and publishing content, and it works on its own around the clock without being prompted each time.

How is Sistava different from project management software?

Sistava is not project management software. You hire AI employees who do the work, not a tool that tracks work done by humans. Your AI employees run sales outreach, write marketing content, answer support tickets, and handle operations on their own, without constant supervision.

How much does Sistava cost?

Sistava has a free plan you can start without a credit card, plus paid plans that scale with how much work you hand to your AI employees. See the pricing page for current plans.

What can AI employees do on Sistava?

Your AI employees take on the recurring work that runs a business: qualifying and reaching out to leads, writing and publishing marketing content, answering support tickets, and handling day to day operations. Each one comes with a role and skill set, so it can start working the day you hire it.

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 you the equivalent of a growth team you can hire in minutes.

The 7 Best AI Sales Tools, Ranked

Comparison — 2026-07-01 — by Mahmoud Zalt

The 7 best AI sales tools compared: Sistava, 11x, Artisan, Apollo, Clay, Outreach, and HubSpot Breeze. Strengths, who each is for, and links to try each one.

AI sales tools fall into two groups: data and engagement platforms that make a human rep faster, and AI agents that do the prospecting themselves. This list ranks the seven that matter for founder-led and small-team sales.

Sistava tops it because you hire an AI SDR that researches, writes, follows up, and books demos as an owned role, not a tool you operate. Every other entry links to its site and a full side-by-side breakdown.

1. Sistava

Works inside your Gmail and CRM, no new stack

FAQ

What is the best AI sales tool for a small team?

For founder-led or small-team sales, Sistava's AI SDR owns the outbound motion end to end without a per-seat contract. Apollo and Clay are strong if you have a human rep who needs data and want to build the workflow yourself.

What is the difference between an AI SDR and a sales engagement tool?

An AI SDR, like Sistava's or 11x's Alice, does the prospecting and outreach itself. A sales engagement tool like Outreach or Apollo gives a human rep sequencing and data to work faster. One replaces the task, the other accelerates a person.
