# The reinvention of B2B customer support software

> B2B customer support software is going through its biggest shift in a decade. Instead of routing customers to a ticket portal, a new wave of tools - led by Plain, alongside Front, TeamSupport and Slack-native upstarts - meets customers inside Slack, Microsoft Teams and Discord, organizes work by account rather than ticket, and treats AI as infrastructure you can bring your own model to. Meanwhile enterprise ITSM incumbents like BMC Software and USU, and platform giant Microsoft, are repositioning around the same idea. This is a story about why the ticket, the defining metaphor of support for twenty years, is quietly being retired.

## Achievements

- Reframed customer support from ticket-centric to account-centric, where a company - not an email - is the unit of work.
- Made native business messaging (Slack, Microsoft Teams, Discord) a baseline expectation rather than an add-on.
- Popularized Bring-Your-Own-Agent (BYOA) AI: teams connect their own models and data instead of accepting locked-in vendor AI.
- Drove real efficiency - customers like n8n grew support volume ~20x while only doubling headcount.

## Latest updates

- **2025-02** — Plain raised a $15M Series A led by Battery Ventures (with Index Ventures and Connect Ventures), pushing total funding to about $21M.
- **2026-01** — Comparison roundups (Plain, TeamSupport) converge on the same three criteria: account-centric design, native Slack/Teams integration, and AI-native architecture.
