- Fiveable
Participated · Equity · Oct 2020
Fiveable started as a free online learning community focused on helping high school students pass AP exams through livestreamed “cram shops,” study guides and an active Discord. The company is evolving into a broader social learning platform that enables student-directed spaces and multiplayer study experiences. It acquired Hours, a virtual study platform, to incorporate shared timers, task lists and study-session features into its roadmap. Fiveable prioritizes growth over monetization for now and keeps its platform entirely free to users. The startup reports more than 7.3 million students have used the platform with 3x year‑over‑year growth, a Discord community of over 25,000 users, and when it previously charged for access it granted more than 3,000 scholarships. The team includes over 50 paid student interns and a diverse staff, and the new funding will be used to grow the team and build more student-led online spaces. Fiveable combines educational content, community, and collaboration to support high school students with a focus on social learning. The platform hosts more than 5,000 pieces of content—study guides, live streamed lessons, and Q&A forums—and serves 1.5 million high school students. Students who studied with Fiveable achieved a 92% pass rate on Advanced Placement exams. The company offers Fall and Spring Fiveable Courses covering all 38 AP subjects with live instruction, practice assignments, feedback, and TA support. Fiveable is building a reimagined social learning community to address isolation and motivation, with an 800-student “Founding Members” team informing product design and a beta community planned for launch this winter. The recently secured funds will be used to propel that social learning experience and expand community offerings. Fiveable builds live-streamed learning sessions and online communities to help high school students prepare for Advanced Placement exams. The company was one of eight startups selected for AT&T’s Aspire Accelerator, which pairs mentorship with exposure to AT&T’s 5G capabilities. As part of the accelerator Fiveable will receive $125,000, including a $100,000 investment from AT&T Aspire, and the program culminates in a December demo day. Earlier, Fiveable won a $25,000 investment in a virtual competition run by ECMC Foundation and Chloe Capital. Founder and CEO Amanda DoAmaral said the company is positioned for growth as remote and online learning expand. The article notes the accelerator connected Fiveable with other top-tier investors and that additional funding is likely. Fiveable is a social learning platform that provides interactive test-prep content, live-streamed lessons, trivia review games, study guides, and a community forum with live support. The company recently dropped its paywall and launched a free, student-first platform while aiming to reach 100,000 student users this spring. Fiveable serves nearly 40,000 students who have achieved a 92% AP exam pass rate using the platform, and it employs more than 180 active content creators. Core offerings include weekly live streams, personalized dashboards, and paid “Cram Passes” for intensive pre-exam review sessions. The company plans to expand the number of AP subjects it covers and to add test-prep resources for the SAT and ACT. Fiveable was founded in 2018 by Amanda DoAmaral and is based in Milwaukee.
