Goodreads
Goodreads is the world's largest social platform for readers, letting people track what they read, rate and review books, get personalized recommendations, and connect with a community of more than 150 million members. Founded in 2006 by Otis Chandler and Elizabeth Khuri Chandler and acquired by Amazon in 2013, it pairs a vast book database with tools for shelving, discovery, reading challenges, and the annual reader-voted Goodreads Choice Awards.
Bookclubs
Bookclubs is a free web and mobile platform that helps book clubs organize themselves - scheduling meetings, tracking reading history, polling on the next book, sending messages, and discovering what to read next. Founded in 2015 out of one Philadelphia book club's messy email chain, it now serves hundreds of thousands of readers and monetizes through publisher and author partnerships rather than charging its members.
Tertulia
Tertulia is a New York-based book discovery and commerce startup that turns the internet's endless chatter about books into personalized reading recommendations, then lets you buy the book in a couple of taps. Named after the informal literary salons of Spanish cafes, it scans social media, podcasts, critics and the wider web to surface the titles people are actually talking about, pairs that with human curation, and wraps the whole thing in a community co-op that lets avid readers become part-owners of the store. In 2025 it expanded beyond readers to authors with Tertulia for Authors, an all-in-one website builder and marketing platform.
Sebastian Cwilich
Sebastian Cwilich is the founder and CEO of Tertulia, a book-discovery company that uses machine learning to surface the books people are actually talking about online. An Argentine-born physicist who spent years at AT&T Labs before reinventing himself in the art market, he co-founded Artsy and built it into the world's largest online fine-art marketplace as its president and COO. With Tertulia he set out to do for books what Artsy did for art: turn scattered conversation into discovery. The company launched in 2022 with $6M in seed funding led by AlleyCorp and, by 2025, pivoted toward author services with a popular automated website builder.
Libby Roin
Libby Roin is the CEO of Goodreads, the world's largest social reading platform with over 150 million members. A Boston College English major turned MIT Sloan MBA, she spent nearly a decade building her way up through Goodreads product teams before taking the top job in January 2022. Along the way she founded Polk Street Press, a children's interactive app studio, and raised over $10 million for Teach for America. She grew up one of seven kids in Oklahoma - daughter of a police officer and a schoolteacher - and brings a pragmatic, community-first sensibility to one of the internet's most beloved book destinations.
