AI Agents for Business: 9 Platforms I Compared for 2026

Picture the operations lead at a 40-person company. On Monday the chief executive forwards an article with one line typed above it: get us some AI agents by Friday.

She already pays for plenty: Microsoft 365 or Google Workspace, plus a CRM. Every listicle she opens ranks its own author's product first and never asks about any of that.

That order is backwards. The best AI agent for a business is usually decided by what the business already pays for, and then by who is going to keep the agent working after launch week.

So the routing starts from the stack. I run Gravity and it sits at number one here too (at least I say so up front), with a plain note on where it is the wrong pick.

What an AI agent does for a business

An AI agent for business is software that takes a recurring job and finishes it inside the tools your company already uses. It reads what came in, decides the next step, drafts or updates what needs changing, and runs on a schedule or a trigger without someone prompting every step.

A chat assistant stops earlier. Ask it for a follow-up email and it writes one, then you copy it into Gmail, find the thread and press send. The writing was the quick part. An agent does the part around the writing: it spots the new lead in the CRM, drafts into the right thread, logs what it did and comes back next week.

So set one rule before connecting anything: nothing reaches a customer until a person approves it. Giving an agent access to email safely covers the rest.

Start with the department, not the platform

Once you know which team gets the agent and which job it takes over, the platform question shrinks to a shortlist. Here is how I would route each one.

My routing, from vendor pages read in September 2026.

Pick the first department with two tests. The task repeats every week, so the agent gets enough runs in a month to prove itself, and one named person owns the result and reads the drafts.

Sales follow-up and invoice chasing usually pass both. Leadership often fails the second, because the executive who wants help has the least time to check it. Of Gravity's 88 launch agents, 21 cover sales and lead follow-up and 11 cover invoices and bookkeeping admin.

How I compared them

Every platform got the same five questions. I did not run a bake-off; this is a close reading of vendor pages, and where a page left a gap, the section says so.

• The pricing page, with a date. Salesforce's numbers come from the 13th. Zapier was read on the 16th and the rest on 17 September 2026.
• The meter. Seats, capacity packs, consumption, executions, tasks or a quote.
• Who builds it, and who keeps it working. At a 40-person company both jobs tend to land on one person who already had a job.
• What it plugs into. The suite first, then the CRM.
• Whether the agent can act or only draft. Acting saves more time and needs tighter approvals to match.

Quick comparison

Monthly list prices read 13 to 17 September 2026. n8n stays in euros; ChatGPT's page showed rupees for my location, so its row has no price.

1. Gravity: best when a team wants the job done without building

This is my product, so discount me accordingly. It is first because nobody at the company designs the agent, wires it up or fixes it later.

You describe the task in plain words, and Gravity matches it to an agent an independent builder already made. At alpha you connect Google Workspace, Slack, Notion, HubSpot, Pipedrive or Xero by signing in, and anything that would message a customer waits for your approval.

Who repairs the agent when an app changes

The builder who published it does. Building an agent has an end date; keeping it working through API changes lasts as long as it runs.

At alpha there is no file upload, database intake, Microsoft 365 or Salesforce connection, so Microsoft and Salesforce shops should start with sections 2 and 4. If your CRM is HubSpot, read the HubSpot AI agent guide too.

Best for

A team on Google Workspace, Slack or HubSpot with a recurring task and nobody spare to build.

Pricing

First agent free, no card. Then Pro at $5 a month during the alpha, or Max at $20 a month for more agents and usage. Buy more usage if you run out. As of September 2026.

Free tier

Yes, your first agent.

Verdict

Apply to the alpha with the one task you most want off someone's desk.

2. Microsoft Copilot Studio: best for a Microsoft 365 company

If the company pays for Microsoft 365, start with Microsoft. Microsoft 365 Copilot is $30.00 per user a month paid yearly and includes Copilot Chat plus a standard harness in Copilot Studio for building agents.

Copilot Studio has its own meter: capacity packs of 25,000 Copilot Credits at $200.00 a month, or pay-as-you-go with no up-front licence, billed for the Copilot Credits consumed at month end. Agents bill a varying number of Copilot Credits per action or response. That makes a pack hard to size in advance, so a month on pay-as-you-go shows your real number first.

Two meters to budget with Microsoft

Seats pay for people and Copilot Credits pay for what agents do, so budget two lines. There is a cheaper seat: Microsoft 365 Copilot Business is "originally starting from $21.00, now starting from $18.00" per user a month paid yearly, or $25.20 monthly.

It is best for a company whose mail, files and meetings already sit in Microsoft 365. Prices are as of September 2026. A free Azure account comes with a $200.00 credit that can be used to create agents.

3. Google Gemini Enterprise: best for a Google Workspace company

The Business edition is "for small businesses and teams, no IT setup needed", from $21 USD per seat per month with a 30-day trial, and connects to Microsoft 365, Google Workspace, HubSpot, Jira and more. That connector list helps a company with a foot in each suite. Standard and Plus, "for organizations that need enterprise-grade IT controls", start at $30 USD per seat per month.

If you have 20 seats or more

Organisations with 20 or more seats can choose pay-as-you-go with a $0 seat fee. I have no usage rate for it to quote, so get one from Google before assuming it beats $21 a seat.

Best for

A Google Workspace company, or one split with Microsoft 365, that wants agents without an IT project.

Pricing

Business from $21 a seat a month, Standard and Plus from $30, as of September 2026.

Free tier

A 30-day trial.

Verdict

Run the trial on one department's task before buying seats for everyone.

4. Salesforce Agentforce: best when sales or service already runs on Salesforce

Agentforce lives inside Salesforce. The agent works beside the pipeline and service records that are already there. I read the pricing page on 13 September 2026. These numbers are older than the rest.

Reading an Agentforce bill line by line

• $0 to start on the Salesforce Foundations tier, which bills consumption above it.
• Flex Credits: $500 per 100,000.
• Conversations: $2 each.
• Agentforce user licence: $5 per user a month, which requires Flex Credits and is not sold on its own.
• Flat Fee Access: $125 per user a month.
• Agentforce 1 editions: from $550 per user a month.

Six ways to pay is a lot of ways to pay. Start on Foundations at $0 and see which meter your first agent trips.

It suits a Salesforce org running sales or service at scale. Read the Salesforce AI agent guide first.

5. ChatGPT: best as the baseline a team starts from

ChatGPT is where many teams start, which makes it the baseline for this page. Its pricing page lists Free, Go, Plus and Pro for individuals and a separate Business & Enterprise tab.

On 17 September 2026 the page served me prices in Indian rupees for my location. Converting them would be a guess at what a US company pays, so I quote no dollar price for ChatGPT.

Best for

A team setting a baseline before buying anything.

Pricing

Business and enterprise plans on a separate tab; no dollar price quoted, as of September 2026.

Free tier

Yes, a Free plan.

Verdict

The baseline to measure the other eight against.

6. Zapier: best for many small automations across many apps

Zapier advertises 9,000+ app integrations, the biggest integration count any vendor put in front of me for this post, and that reach is the reason to be here.

Agents share a menu with Zaps

The product menu lists Agents, "Create your own AI assistants for any task", beside Zaps, Tables, Forms, Canvas, Chatbots and Zapier MCP. The agents pricing page showed no readable number on 17 September 2026, so Agents get no separate price.

Every automation is still yours to build and repair. Zapier bills by task, so read Zapier pricing explained before the first invoice lands.

Best for

Dozens of small automations across apps no single suite covers.

Pricing

Free at $0. Professional from $19.99 a month ($13.33 billed annually). Team from $69 a month ($66.67 billed annually). As of September 2026.

Free tier

Yes.

Verdict

The widest reach here, for a team with someone who enjoys building.

7. n8n: best for a technical team that wants control

n8n suits a team with an engineer who wants to own the logic. It also has a self-hosted option.

The meter is the workflow execution, and Starter allows unlimited steps inside each one, which favours long workflows. n8n pricing explained covers what counts as an execution.

Starter, Pro and Business in euros

As of September 2026, in euros as the page shows them: Starter €20 a month billed annually for 2.5K executions, Pro €50 for 10K, Business €667 for 40K. The free trial needs no credit card.

8. Lindy: best for one assistant across inbox, meetings and Slack

Lindy calls itself "The AI teammate that will 3x your output", and its features target one person's day: inbox management, replies drafted in your voice, meeting recording and notes, daily briefs, scheduled routines and a Slack-native teammate, with approvals built in.

The unit to watch is the person. Each user carries an allowance of Lindy credits, so the bill grows with headcount.

One person's work or a department's

Lindy fits work that belongs to one person. For a department's shared process, Gravity vs Lindy sets the two side by side.

Best for

Managers who want one assistant for their own inbox and meetings.

Pricing

Plus $29.99, Pro $99.99 and Max $199.99 per user a month, with 3k, 15k and 35k Lindy credits per user. Enterprise through sales. As of September 2026.

Free tier

A 7-day free trial.

Verdict

Multiply by headcount before you roll it out to a department.

9. Relevance AI: best for an enterprise buying an AI workforce

Relevance AI's pricing page has one plan: Enterprise, custom, behind a Talk to sales button. There is no self-serve price, so nothing here compares on a number. It is built for a big buyer. The plan lists unlimited agents, tools and users, 2,000+ integrations, calling and meeting agents, evaluations and A/B testing, SSO, RBAC, audit logs and a dedicated account manager.

Best for

An enterprise buying an AI workforce with a vendor in the room.

Pricing

Enterprise only, custom, through sales. As of September 2026.

Free tier

None on the pricing page.

Verdict

Far more than a 40-person team needs for its first agent.

Smaller team, same job

The ops lead from the top of this post does not need unlimited users. Gravity vs Relevance AI is the closer comparison at that size, and enterprise AI agent platforms covers the buyers who do.

What AI agents cost a business

Here is the ops lead's company at list price, with ten people wherever a vendor charges per person. These are list prices for different things, which is the point.

Three lines buy seats for people, one buys a pool of Copilot Credits for agents, one buys a task plan and one buys executions. A Microsoft company whose ten Copilot seat holders also run busy agents could carry both Microsoft lines: $300 + $200 = $500 a month.

Which one should you choose?

Start from the suite you pay for. A Microsoft 365 company should open Copilot Studio first; Microsoft 365 Copilot, at $30 a user a month paid yearly, includes a standard harness for building agents. A Google Workspace company should run the Gemini Enterprise trial on one department.

A Salesforce org with sales or service at scale belongs on Agentforce.

A technical team that wants control, or wants everything on its own servers, should pick n8n. Many small automations spread across many apps point to Zapier.

Lindy fits one assistant across inbox, meetings and Slack; count the seats first. An enterprise buying an AI workforce with a vendor in the room should call Relevance AI.

My own bias, stated plainly: a team that wants a job done without building should apply to the Gravity alpha. That goes double if its work runs through Google Workspace, Slack or HubSpot.

Running the business alone is a different question with different answers. The best AI agents for small business covers that one.
