DevRev exists to close the gap between the people who hear about problems and the people who fix them. Founded in 2020 by Dheeraj Pandey, the co-founder and former CEO of Nutanix, and Manoj Agarwal, a former Nutanix engineering SVP, it unifies customer support and product development on one platform: tickets link directly to the product parts and engineering work they relate to, so a support conversation and the bug it uncovered live in the same system instead of being lobbed between Zendesk and Jira.
The AI story has grown ambitious. DevRev now describes its platform as "Computer," built on a knowledge graph it calls native shared memory, with Agent Studio for building AI agents, enterprise search across live data from connected apps, AirSync to mirror data in from tools like Jira, Salesforce, and Slack, and conversational analytics that answer questions in plain English. For support teams specifically, its agents deflect customer questions, triage and route issues to the right owners, and surface product insights from ticket volume. The company raised a $100.8 million Series A led by Khosla Ventures in 2024, reaching unicorn status at a $1.15 billion valuation.
Commercially it moved to freemium: a free Mini tier with one-click connectors, then consumption-based Pro and Max tiers priced through sales.
DevRev suits product-led software companies that feel the support-to-engineering handoff as daily friction, and buyers comfortable betting on an expansive platform vision rather than a narrow tool. If you want a simple help desk with a bot, this is more machine than you need; if support is upstream of your roadmap, it is a genuinely different idea.

Plain is the support platform that talks to engineers without condescension. Founded in London around 2020 by Simon Rohrbach, previously Deliveroo's design director, and Matt Vagni, it is API-first, fast, and deliberately lean, built for B2B and developer-facing companies whose customers file sharp technical questions in shared Slack channels, Discord servers, and email. Its customer list is a tour of modern developer tooling: Vercel, Cursor, Raycast, Sanity, Laravel, n8n, and Stytch, and Sanity reported a 120 percent jump in team satisfaction after switching from Zendesk.
All those channels flow into one timeline per customer, with SLAs, escalation paths, and the workflow niceties of a grown-up help desk. The AI comes as a named pair: Ari, a customer-facing agent that answers technical questions from your docs and past threads, and Sidekick, an internal assistant that helps agents draft, label, and triage. A pointed commercial choice: every plan includes Ari with no per-resolution charges, a deliberate contrast to the outcome-billing trend, though AI usage is metered through monthly credits.
Plain raised a $15 million Series A led by Battery Ventures in early 2025, about $21 million in total, and publishes its pricing: Foundation at $35 per seat per month, Horizon at $299 a month for growing teams, and a custom Frontier tier, with a 50 percent startup discount.
Choose Plain if you are an engineering-led B2B company that finds the incumbents heavy and the e-commerce tools irrelevant. It is the tasteful, technical option, and the flat AI pricing makes costs predictable in a category where the meter usually runs by the ticket.
