FeedbackPanda

FeedbackPanda was a software-as-a-service product for online teachers of English as a second language, many of whom taught Chinese children through online platforms. It let teachers build reusable feedback templates so they could write post-lesson student reports faster.^{Source [1]Source [2]}

The product started as a tool for co-founder Danielle Simpson, who was teaching online at the time, and Arvid Kahl built the first prototype on weekends while working as a software engineer. Growth came mostly from word of mouth among teachers.^{Source [1]Source [2]}

The founders never raised outside funding and never hired employees. They reported reaching about $55,000 in monthly recurring revenue and about 5,000 customers before the 2019 sale to SureSwift Capital, a firm that buys SaaS businesses from independent founders; those figures are self-reported.^{Source [3]Source [2]}

Danielle Simpson and Arvid Kahl built FeedbackPanda in 2017 as a tool to speed up the feedback reports online English teachers wrote for students. The founders announced on October 18, 2019 that they had sold the bootstrapped company to SureSwift Capital, about two years after starting it, for what They Got Acquired reported as a seven-figure sum. As of October 2, 2026 the feedbackpanda.com domain no longer serves the product and shows unrelated content.^{Source [1]Source [3]Source [2]Source [4]}
