Plain is an API-first customer service platform for modern tools. We want to bring engineering and customer service teams together by creating a modern opinionated platform that's built to be built with.

Most support platforms treat each interaction as a transaction: ticket in, ticket out, measure speed and deflection.

We take a different approach.

TeamSupport is built on a simple insight: Every customer interaction is a signal about customer health, product quality, and future revenue opportunities. The companies that capture and act on these signals grow faster and churn less.

What makes us different: - Customer intelligence, not just ticket management. We don’t treat customer interactions as one-off transactions. Our platform connects every touchpoint to each account, giving you a full view of health, sentiment, and churn risk — all so you can intervene when needed and capitalize on expansion opportunities. - Product intelligence built in. Your support tickets are your best source of truth about what’s working (or not) in your product. We surface all those patterns, trends, and insights so your product and engineering teams build what your customers really need. - Holistic post-sales platform. We’re connecting onboarding, support, renewal, and expansion into one unified platform. Because when you’re in B2B software, the real key to long-term growth isn’t just closing new deals — it’s keeping customers happy, successful, and expanding.

Who it’s for: Small and medium-sized B2B companies who are tired of reactive support and ready to turn customer interactions into competitive intelligence and growth.
