# SleekFlow vs Fin: which AI agent fits your customer conversations?
*Felicia Ng — Senior Content Specialist*
## Summary
- SleekFlow runs AI agents for sales, marketing and support on WhatsApp and Instagram, and Fin runs one on your helpdesk.
- Fin replies to conversations customers start, and has no way to send a campaign itself.
- Where Fin invests in resolving tickets on the helpdesk you keep, SleekFlow invests in the messaging relationship.
- Before comparing feature lists, split last month's conversations into the ones customers started and the ones you started.
- If most of your revenue comes from conversations you begin, that work sits outside Fin entirely.
***Author's note:**** this comparison reflects SleekFlow's assessment; product details are accurate as of publication and may change, so verify with each provider. Full note below.*
You want an AI agent that answers real customer questions, and Fin can sit on top of the helpdesk your team already knows, whether that's Intercom, Zendesk, Salesforce or HubSpot. No migration, no retraining, and your macros and reports stay where they are.
That still holds if most of your customers email you or open a chat window on your site. Or maybe your customers have moved. They message you on WhatsApp or Instagram, and the same thread carries a question before they buy and a delivery query a week after.
Then the AI agent is only part of the decision. You're also choosing where your sales, marketing and support conversations live, and moving that means migrating a live WhatsApp number and retraining the people who answer it.
Below is how Fin and SleekFlow compare on the parts of that choice that are hardest to undo.
## Is SleekFlow or Fin better for teams selling on messaging apps?
In our view, SleekFlow is the better fit when you want AI agents, a shared inbox and broadcast campaigns in one platform, running sales, marketing and support over WhatsApp, Instagram and other messaging apps. The clearest difference is direction: Fin is built to answer, and SleekFlow both answers and starts conversations. Fin is the better fit when you want to keep your current helpdesk and add an AI agent that also covers email and, for some teams, phone.
SleekFlow describes itself as "the AI suite for revenue-driving conversations." Fin describes itself as "the Customer Agent company delivering perfect customer experiences." The two descriptions point at different buyers.
Agents on messaging apps are no longer unusual. On Meta's earnings call of 29 July 2026, the company said there were "already more than 1 million businesses using them to talk to their customers or complete sales every week" on WhatsApp and Messenger.
## Fin, Intercom, Intercom 2: which one are you actually buying?
This trips people up, because four things now share two words.
| **Name** | **What it is** |
| --- | --- |
| **Fin, the company** | The company was formerly called Intercom, renamed on 12 May 2026. Salesforce completed its acquisition on 10 Sep 2026. |
| **Fin, the AI agent** | The product you shop for. It runs on top of a helpdesk and is sold in three lines: Fin for Service, Fin for Sales and Fin for Ecommerce, plus Fin Voice. |
| **Intercom** | The helpdesk product, still sold under that name. |
| **Intercom 2** | The rebuilt helpdesk, adding workforce management, real-time issue detection and QA. |
The practical point is the second row. Fin always sits on a helpdesk. Its own documentation describes running it with Intercom, Zendesk, Salesforce, HubSpot, Freshworks or a custom helpdesk, and no page describes running it on its own. So choosing Fin means keeping, and paying for, whatever sits underneath it.
That's why this page compares AI agents. If you're weighing helpdesk platforms instead, our [SleekFlow vs Intercom comparison](https://sleekflow.io/blog/intercom-comparison) covers inboxes, ticketing and seat pricing.
## SleekFlow vs Fin at a glance
| **Category** | **SleekFlow** | **Fin** |
| --- | --- | --- |
| **Best for (our assessment)** | SME to enterprise B2C brands that sell, market and support over messaging apps and want agents, inbox and campaigns in one platform | Teams that want one AI agent on the helpdesk they already run, starting with support and extending into sales and commerce |
| **What the agent does** | Qualifies leads, books appointments, resolves support issues, and runs campaigns and journeys | Resolves support conversations, qualifies inbound leads, and handles commerce questions during a live session |
| **Who starts the conversation** | Either side. Customers message in, and SleekFlow sends broadcasts and journeys out | The customer. Fin replies to what arrives; on Intercom it can also pick up replies to messages the helpdesk sent |
| **Channels** | WhatsApp Business API, Instagram, Messenger, SMS, TikTok, WeChat, LINE, Telegram, Viber. Gmail, Outlook and VoIP calls listed as coming soon | Web and in-app Messenger, email, voice (select customers, on custom pricing), WhatsApp, Instagram, Messenger, SMS, Slack, Discord |
| **Number of agents** | Several: Inbound, Outbound, Data Analyst and Copilot agents in AgentFlow | One customer-facing agent, with multiple paths inside it. Copilot serves teammates and Operator serves customer operations |
| **Where it runs** | Its own inbox. SleekFlow is the system your team works in | On top of a helpdesk: Intercom, Zendesk, Salesforce, HubSpot, Freshworks or a custom one |
| **What you're billed for** | Monthly active contacts, with 10 user accounts on Pro and Premium and AI agents inside a monthly credit allowance | Outcomes, one per conversation, with a monthly minimum on non-Intercom helpdesks, plus helpdesk seats if you use Intercom |
## How SleekFlow and Fin differ, feature by feature
Every capability below comes from each vendor's own live product, help and pricing pages, checked in September 2026. The two agents overlap on the basics, so each section focuses on the difference that would change your decision.
### What each agent can do
Both agents answer from your own knowledge and take actions in other systems. Fin is designed as a single agent with deep procedural logic, working through your helpdesk. SleekFlow's AgentFlow runs several specialised agents against the same conversations, with the Inbound Agent handling sales enquiries and support requests end to end.
Fin's agent:
- Procedures for multi-step queries, with business logic and approvals
- Data Connectors that look up and act in Shopify, Stripe and Salesforce
- Answers drawn from help articles, internal content, PDFs and URLs
- One customer-facing agent, with different paths for different audiences
SleekFlow's agents:
- An Inbound Agent that qualifies leads, books appointments and resolves issues
- An Outbound Agent, a Data Analyst Agent and a Copilot Agent alongside it
- Playbooks that call APIs in sequence, from availability checks to payments
- Knowledge built by crawling your website and scanning internal docs
- A visible source on every AI reply
**What this means for you:** one deep agent suits a team with a few high-volume, well-defined jobs, and a set of specialised agents suits a team where sales, support and reporting pull in different directions.
### Who starts the conversation
This is the difference that decides most shortlists, and it is a design choice rather than a gap. Fin is built as a responder: it answers what arrives, and on Intercom it picks up when someone replies to a message the helpdesk sent. SleekFlow sends as well as answers, so a campaign, the reply it earns and the sale that follows sit in one thread.
What Fin handles:
- Replies to conversations customers start, across web, email, WhatsApp, Instagram, Messenger, SMS and voice
- On Intercom, picks up when a customer replies to an Outbound message or a Workflow
- Proactive sending isn't supported on other helpdesks; Fin's help centre points those teams to Intercom
- Intercom's campaign tools, Series, Posts, Checklists, Product Tours and Surveys, sit in the Proactive Support Plus add-on at US$99 a month
What SleekFlow sends:
- [Broadcast campaigns](https://sleekflow.io/broadcast-campaign) on WhatsApp, Messenger, WeChat, Telegram, SMS, Viber and LINE
- Flow Builder journeys triggered by [Click to WhatsApp Ads](https://sleekflow.io/blog/click-to-whatsapp-ads-automation)
- An Outbound Agent inside AgentFlow, working alongside the Inbound Agent that answers
- Campaigns are included in the plan, with WhatsApp and SMS message fees charged on top, as they are with any provider
**What this means for you:** if the conversations that make you money are ones you start, that work sits outside Fin and is priced separately, so the fair comparison is the whole stack you'd need rather than the agent on its own.
### Channels
Fin and SleekFlow both run on WhatsApp, Instagram, Facebook Messenger and SMS. Past that shared core the lists diverge, and neither is a superset of the other: Fin adds email, voice, Slack and Discord, and SleekFlow adds TikTok, WeChat, LINE, Telegram and Viber.
Fin covers:
- Email, plus its own web and in-app Messenger
- Voice, offered to select customers on custom pricing, running on its own low-latency model
- WhatsApp on the official WhatsApp Business API, plus Instagram, Messenger and SMS
- Slack, Discord and an agent API for custom channels
SleekFlow covers:
- WhatsApp Business API, as an [official WhatsApp Business Solution Provider](https://sleekflow.io/channels-integrations/whatsapp)
- Instagram, Facebook Messenger and SMS
- TikTok, WeChat, LINE, Telegram and Viber
- Gmail, Outlook and VoIP calls, which it lists as coming soon
**What this means for you:** a queue that's mostly email and phone points to Fin today, and customers on LINE, WeChat or Telegram point to SleekFlow, because each of us covers channels the other doesn't.
## How much do SleekFlow and Fin cost?
Fin charges for outcomes, such as a resolution, a handoff or a qualified lead, with one outcome billed per conversation, plus seats if you run the Intercom helpdesk. Its pricing page puts the value plainly: as Fin handles more conversations, your support costs go down. SleekFlow charges by monthly active contacts, with AI agents included inside a monthly credit allowance, so the bill tracks the size of your audience rather than the volume of tickets it produces. Both publish list prices in US dollars, so the cleanest comparison is Fin's pricing page next to [SleekFlow's pricing page](https://sleekflow.io/pricing).
The more useful question is how each bill behaves as your business grows.
How Fin's bill grows:
- It rises with the work the AI does, because every resolved or handed-off conversation is an outcome
- A qualified lead is priced higher than a resolution
- On a helpdesk other than Intercom, a monthly minimum number of outcomes applies
How SleekFlow's bill grows:
- It rises with the number of contacts who message you, or whom you message, in a month
- AI replies don't add a per-answer or per-resolution charge, and usage sits inside the monthly AI agent credit allowance set by contact tier in the [Fair Use Policy](https://sleekflow.io/fair-use-policy)
- Pro and Premium include 10 user accounts, so adding agents doesn't add seat fees up to that point
On both platforms, WhatsApp and SMS usage is charged on top of the plan. SleekFlow bills these per its rate card plus a number hosting fee, and Intercom bills outbound WhatsApp messages and SMS segments, with inbound WhatsApp conversations free. WhatsApp messaging fees are set by Meta and vary by country and message category.
**What this means for you:** Fin's bill grows fastest when your AI handles more conversations, and SleekFlow's grows fastest when more customers message you, so the better deal depends on which of those two numbers climbs quicker in your business.
## Which should you choose, SleekFlow or Fin?
The order that works is goal first, channels second, billing last, because the goal decides what you're buying and the channels decide what's possible.
SleekFlow makes sense if:
- You want the agent, your team and your campaigns working from the same conversations
- Your customers reach you on TikTok, WeChat, LINE, Telegram or Viber as well as WhatsApp and Instagram
- You'd rather budget by active contacts than by each outcome the AI completes
Fin makes sense if:
- You're keeping Intercom, Zendesk, Salesforce or another helpdesk and want AI on top
- Most of your volume comes through email or phone, where Fin has products today and we list ours as coming soon
- You handle health data and need HIPAA coverage, which Fin's certification list carries and ours does not
Some teams run both for a while, keeping a helpdesk for email while chat moves to SleekFlow. That works as a bridge, though it means paying two platforms for AI on one customer base, so it's best with an end date.
## SleekFlow vs Fin: the verdict for brands that sell over chat
For brands whose customers buy, ask and come back through WhatsApp and other messaging apps, SleekFlow puts the agent, the inbox and the campaigns in one place. For teams whose support runs through a helpdesk they want to keep, Fin adds an AI agent without changing that setup.
[ETS Global](https://sleekflow.io/customer-stories/ets-global-customer-story), the international arm of ETS, provides assessments and learning solutions to institutions and learners worldwide. Its email open rates were falling, and Gen Z audiences expected faster, more conversational replies than email could give. The team moved customer conversations to WhatsApp with SleekFlow, using Broadcast Campaigns, Flow Builder and the inbox, plus an AgentFlow AI agent trained on its own information.
Results:
- 63% increase in engagement
- Significant improvement in reply rates
- Better time management and operational efficiency

### Can Fin send WhatsApp campaigns or broadcasts?
No. Fin is built to answer conversations customers start, not to begin them. On Intercom it can respond when a customer replies to an Outbound message or a Workflow, and on other helpdesks Fin's help centre says proactive messages aren't supported and points those teams to Intercom. Intercom's own campaign tools, including the Series builder, sit in a paid add-on. SleekFlow sends broadcast campaigns on WhatsApp, Messenger, WeChat, Telegram, SMS, Viber and LINE from the plan itself, with Meta's message fees charged on top.
### What does the Salesforce acquisition mean for Fin customers?
Salesforce completed its acquisition of Fin on 10 Sep 2026. Its announcement says that "as part of Salesforce's AI Labs, Fin will continue to serve its customers, advance its AI agent capabilities, and build market-defining AI models and technology." Neither company's announcement mentions changes to Fin's pricing or to the Intercom brand. If you're signing or renewing a multi-year contract, it's a reasonable moment to ask how pricing and product changes are handled in your terms.
### What counts as a billable outcome in Fin, and an active contact in SleekFlow?
Fin bills an outcome when it resolves a conversation end to end, or successfully executes a Procedure ending in a handoff. Only one outcome is charged per conversation, even when Fin takes several actions, and a qualified lead is priced higher than a resolution. SleekFlow counts a Monthly Active Contact when someone sends you a message or receives one from you through the inbox, Flow Builder, an AI Agent, API calls or WhatsApp coexistence during a billing month. One-way broadcast recipients who don't reply aren't counted.
### How do SleekFlow's AI agent credits work?
SleekFlow's Fair Use Policy sets a monthly AI agent credit allowance by contact tier. It starts at 5,000 credits a month at the 500-contact tier and rises to 80,000 at 8,000 contacts, so the allowance grows with your plan rather than being charged per reply or per resolution. The allowance lives in the policy rather than on the pricing page, so both are worth reading before you pick a tier.
### Can Fin work with Zendesk?
Yes. Fin's help centre lists Zendesk alongside Intercom, Salesforce, HubSpot and Freshworks, and Zendesk setups are arranged through Fin's sales team rather than self-serve. One limitation is documented: Fin can't respond to proactive messages sent through Zendesk, and its help centre directs teams that need that to use Fin with Intercom instead. A monthly minimum number of outcomes also applies on helpdesks other than Intercom.
### What should I know before connecting WhatsApp to Fin through Intercom?
Intercom's help centre lists WhatsApp as a paid channel on the Essential, Advanced and Expert plans. You'll need a verified Meta Business Account, a WhatsApp business profile and a phone number, and the WhatsApp Business Account has to be billed in US dollars, which Meta doesn't allow you to change after creation. Once connected, the number can only be active in one place, so it has to be disconnected before it runs anywhere else. The same number question applies to any move between providers, including to SleekFlow.
