Plain raises £12m Series A led by Battery Ventures to build the future of B2B customer support

Plain, the platform transforming B2B customer support, today announced it has raised £12 million in Series A funding led by Battery Ventures, with continued participation from Index Ventures and Connect Ventures. The funding will accelerate Plain’s mission to build a collaborative, AI-powered support platform, expand into customer success, and establish its first U.S. office in San Francisco.

Founded by Simon Rohrbach and Matt Vagni, who helped scale Deliveroo from 10 to 2,000 employees, Plain draws on its founders’ deep experience designing systems for high-growth businesses. Simon led Deliveroo’s 40-person content, research, and design team, while Matt played a key role in building its design systems and internal tooling. This hands-on expertise shapes Plain’s approach to modernizing corporate, B2B support workflows as employees increasingly work off email and in new communication channels.

The B2B support landscape is changing, and Plain is poised to lead. Plain is trusted by companies like Sanity, Laravel, Stytch, and Raycast to consolidate their customer communication workflows and deliver faster, more effective outcomes. As B2B support evolves, three major shifts are redefining the way businesses engage with their customers:

1. A shift to real-time, collaborative channels: Companies are moving from email and ticketing systems to high-touch platforms like Slack and Microsoft Teams, where conversations feel more personal and immediate.
2. Collaboration across teams: The lines between customer support and success are blurring. Teams are working more closely with engineering and product to solve issues, increasing the need for platforms that foster teamwork.
3. AI-powered workflows: To stay ahead of customer expectations, companies are adopting tools that automate repetitive tasks, extract insights, and adapt in real time.

Plain enables modern enterprises to consolidate high-touch communication channels like Slack, Microsoft Teams, and Discord alongside traditional platforms like email and chat, creating a unified platform for customer conversations. By fostering collaboration between support, engineering, and customer success teams, Plain helps businesses resolve support issues faster. Its AI-powered workflows automate repetitive tasks, draft detailed responses, and extract valuable product insights from customer interactions, empowering teams to deliver better support and stay closer to customers’ needs.

Plain will use the £12 million Series A funding to enhance its platform capabilities – adding new, innovative features and deeper integrations – as well as to grow its team and open a San Francisco office to better serve its growing U.S. and Bay Area customer base. The company has plans to double its workforce across sales, marketing, design, and engineering over the next six months to meet increasing product demand.
