Quill is a computer software company MoreLess

Quill, operating under the domain quill.chat, was a communication software company established to provide a more focused alternative to mainstream team messaging platforms like Slack. The company was founded in 2018 by Ludwig Pettersson, who was previously the creative director at Stripe and was recognized for his contributions to the payment company's user-focused design. The platform officially launched in February 2021 after a period in beta.

The business operated in the competitive team collaboration and communication software market, targeting teams that felt overwhelmed by the constant notifications and unstructured conversations typical of other platforms. Quill's business model was freemium, offering a free basic service with paid tiers for additional features. The paid plan was priced at $15 per user per month, providing expanded message history and storage, with an enterprise plan also available.

Quill's core service was a messaging application designed to minimize distractions and enhance productivity. Its unique selling proposition was its emphasis on structured communication. Key features included strictly threaded conversations within channels to prevent chaotic waterfalls of messages, an activity feed that prioritized important conversations, and nuanced notification controls to reduce interruptions. The platform allowed users to share files, integrate with other applications, and conduct video chats, all within an interface designed for focus. The service was available across all major operating systems, including web, desktop (MacOS, Windows, Linux), and mobile (Android, iOS).

The company secured initial seed funding of $2 million from Sam Altman and General Catalyst. This was followed by a significant Series A funding round of $12.5 million in October 2019, led by Index Ventures. This round valued the company at $62.5 million. However, the company's journey as an independent entity was short-lived. In December 2021, Twitter (now X) acquired Quill for an undisclosed amount. Following the acquisition, the Quill application was shut down on December 11, 2021, and the team was integrated into Twitter to work on improving its direct messaging capabilities.
