Pylon is what a help desk looks like when you start from Slack instead of email. Founded in late 2022 by Advith Chelikani, Marty Kausas, and Robert Eng through Y Combinator, it noticed that modern B2B support had quietly moved into shared Slack Connect and Teams channels, where traditional ticketing systems are blind. Pylon makes those channels first-class support surfaces: threads become tracked issues with owners and SLAs, AI answers routine questions in-channel from your docs and past conversations, and everything rolls up into proper reporting alongside email and in-app chat.
The company has grown at a pace that turned heads, reporting five-fold-plus revenue growth in consecutive years, over a thousand B2B customers including Together AI, Cognition, Temporal, AssemblyAI, and HackerRank, and a $31 million Series B co-led by Andreessen Horowitz and Bain Capital Ventures in 2025, bringing total funding to $51 million. Its positioning has sharpened into "the agentic support platform" for B2B, with a family of named AI agents, Support, Assist, Background, and Slack, plus account intelligence that surfaces health signals across every customer conversation.
Pricing starts at $59 per seat per month billed annually, with AI capabilities sold as add-ons, including a per-resolved-ticket component for the autonomous agents; there is no free plan, and Enterprise carries seat minimums.
Pylon is the obvious shortlist item for post-sales teams at B2B software companies, especially where customers already live in shared Slack channels and the support, success, and solutions functions blur together. If your support is consumer email and chat volume, the e-commerce and SMB tools in this directory will fit better.

Unthread is an AI-native helpdesk built directly into Slack and Microsoft Teams, and it is one of the few tools in this space that serves internal and external support from the same product: IT, HR onboarding and employee support alongside customer support and RevOps. Intake is genuinely omnichannel (Slack, Teams, email, web chat and API), with a self-learning knowledge base, SLA and SLO tracking, on-call routing, conditional workflow automation, analytics with gap analysis, and more than 100 native integrations.
The Slack mechanics are the most granular of any pick here. Ticket creation is described as Slack-native with zero training: a conversation in a channel becomes a tracked ticket, and an employee who wants privacy DMs the support bot instead. Automations fire on a message, an emoji reaction, or a slash command, and every automation starts and ends in Slack. For drafting, a support agent either reacts to a message with the thinking-face emoji or uses the "Suggest AI Response" shortcut, and the AI returns a human-readable answer plus links to the documentation it drew on. The agentic layer reads incoming tickets, assigns category and priority, answers from connected knowledge bases, updates documentation from resolved tickets, and can run actions before handing off to a person. Unthread claims it deflects 40 percent on day one.
Jake McCloskey and Tom Bachant founded the company in 2021 in New York, went through Y Combinator's Summer 2022 batch, and have raised roughly $3.5 million. The customer list is unusually strong for a company that size: Intuit, Automattic, Lemonade, Cribl, Hopper, xAI, Decagon, Stord, Apollo GraphQL, Incode, thirdweb and Defense Unicorns.
Pricing is published, per agent, with a five-seat minimum and a 14-day trial but no free tier. Basic is $50 per agent per month and caps at 100 conversations a month; Pro at $75 adds the AI automation, self-learning documentation, knowledge base sync, analytics and custom workflows; Enterprise is custom and brings SSO, HRIS integration, HIPAA and BAAs, dedicated hosting and Enterprise Grid support. As with Siit, the AI lives one tier above the entry price. Choose Unthread if Slack is your system of record and you want one helpdesk covering both employees and customers. Skip it if you need a full ITSM platform with asset and change management, which this deliberately is not.
