Plain secures £4.8m in seed funding co-led by Connect Ventures and Index Ventures to scale its customer support platform.
The seed round was co-led by Connect Ventures and Index Ventures to accelerate team expansion and product growth.
Plain provides a customer support platform designed to modernise B2B workflows and consolidate communication channels. The system helps businesses manage interactions across platforms like Slack and email.
London-based customer support platform Plain has secured £4.8m in a seed funding round co-led by Connect Ventures and Index Ventures. The round also drew participation from a roster of angel investors and industry operators. The newly raised capital will be directed towards expanding the company across marketing, sales, design and engineering functions as it scales its operations following the launch of its open beta.
Founded in 2020, the startup addresses what it views as a disconnect between modern engineering standards and legacy customer service software. By building an API-first platform that integrates directly with internal company systems, Plain attempts to bridge the gap between technical teams and customer support agents.
From the founder
"The fundamental problem we’re solving is context: Plain offers a single source of truth for customer interactions, powered by companies’ own systems and data – so when someone gets in touch with a problem, the company immediately knows who they are, what their order is, what’s happened so far – and can resolve it in a single click. Customer service teams are often left unsupported by their colleagues in engineering because traditional systems can be hard to integrate and build with. As a result, customer support teams are left to contend with poorly integrated tools, fragmented data, and disconnected systems. We’re designing Plain from day 1 with both engineering and customer service teams in mind, so it can be quickly and easily customised, rather painfully ‘hacked’ after the fact."

Investor perspective
