The best AI coworkers for agencies

Role it fills: Runs the business: site, sales, support and marketing

For a small team that wants one AI teammate to take work off everyone's plate, Crevio covers the most ground of anything we rank. It doesn't stop at drafting: it acts in the business, on a schedule or when something happens, like a new order or an inbound email, and it asks before anything consequential. The tradeoffs are credit-based billing that rises with use, a 2.5% fee on sales you take through it, no Microsoft Teams app, and a younger company with fewer public reviews than the big names.

Role it fills: Generalist teammate for reports, ops, outreach and internal apps

Viktor is the best pure AI coworker for a team that already runs on Slack or Teams. It has excellent reviews, no per-seat fees, and real controls: each tool can run automatically or ask first, with approve and reject cards in the channel. It's built for teams with an existing stack, not for running a website or taking customer payments, and long background tasks can burn credits quickly.

Role it fills: Seven role-based AI employees, from inbox to receptionist

Marblism is the best value for role-based help: seven AI employees, including a phone receptionist, for $24 a month on annual billing, with unlimited businesses and team members. Each role is shallower than a dedicated tool, it doesn't live in your team's chat, and a 50-hour monthly cap limits heavy use.

Role it fills: Build company-specific agents on your docs and tools

Dust is the best build-your-own option for teams that want agents grounded in their own documents and available in Slack. You design the coworkers yourself, which takes time, and prices are in euros.

Role it fills: Autonomous agent team that builds and markets a company

Polsia's agents work every day without being asked, which makes it one of the most autonomous coworkers here. But you manage it from its own dashboard rather than your team's chat, and the fine print is heavy: 3% of your customer payments, 20% of your ad spend, no refunds, and credits charged for fixing its own bugs.

Role it fills: Build multi-agent teams for sales, support and ops

Relevance AI is a powerful builder for sales and ops teams at established companies. For a small team it's a lot of setup, billing has two moving parts, and the public pricing page now says only "talk to sales."

Role it fills: Back-office teammates on your own AI subscription

Squad has some of the best controls here, with scoped access, a secrets vault, approvals and full run logs, and a flat price with no markup on AI usage. The real cost is $99 plus a $100 to $200 model subscription, there's no trial, and it's very new.
