“### 1. [Pylon](https://www.usepylon.com/ — Best overall for B2B SaaS”
“- Native Slack Connect support.”
“- Native Microsoft Teams support.”
“- Account-based ticket management.”
“- AI agents for customer support.”
“B2B SaaS focus | Excellent | Excellent | Excellent”
“One thing to note: Microsoft Teams support requires the Advanced or Enterprise plan.”
“### 2. [Plain](https://www.plain.com/ — Best modern support infrastructure”
“Its biggest advantage is its developer-friendly architecture and ability to connect support workflows with engineering.”
“- API-first architecture.”
“- Native Slack Connect integration.”
“Microsoft Teams is available on its higher-tier plans.”
“### 3. [ClearFeed](https://clearfeed.ai/ — Best if you want to keep your existing ticketing system”
“ClearFeed is particularly interesting because it can work as a layer on top of an existing ticketing platform.”
“- Two-way synchronization.”
“- Support for Zendesk, Jira Service Management, Salesforce and Freshdesk.”
“Important: Make sure you evaluate ClearFeed's External Helpdesk offering, rather than assuming all its integration editions support external Slack Connect channels.”
“### 5. Zendesk — Best established enterprise helpdesk”
“- Advanced ticket management.”
“- Extensive reporting.”
“The main limitation is that its Slack and Teams integrations are not equivalent to having Slack Connect and external Teams channels as first-class customer support channels.”
“### 4. [Intercom](https://www.intercom.com/ — Best for AI-powered customer support”
“- AI support agent (Fin).”
“Its Slack integration supports two-way conversations, including customer messages and replies synchronized between Slack and Intercom.”
“However, I would distinguish its Slack capabilities from its Microsoft Teams capabilities: verify the exact customer-facing Teams workflow before choosing it for both channels.”
“### 6. Jira Service Management — Best for technical support”
“- Native Slack and Microsoft Teams request intake.”
“- Incident management.”
“- Integration with Jira Software and Confluence.”
