Digital Publishing Startup Spines Raises $64 Million in Funding
Digital publishing startup Spines has raised $64 million in total equity and debt funding led by Zeev Ventures. The AI-powered platform has reached an annual revenue run rate of $50 million.
The digital publishing platform Spines, founded by Yehuda Niv, has secured $29 million in equity funding and a $35 million debt facility from Twelve, a debt fund established by the Galai brothers. The funding round is led by Oren Zeev’s Palo Alto-based fund Zeev Ventures, alongside Alef Fund and Dan Senor.
Spines automates the self-publishing process for independent authors using artificial intelligence agents. The platform handles text editing, proofreading, book cover design, and layout formatting. Following production, Spines distributes titles across major digital, audio, and print channels, including Amazon and Barnes & Noble. To avoid inventory overhead, physical copies are printed individually on demand.
The startup currently generates an annual recurring revenue run rate of $50 million, up significantly from $5 million during its Series A round two years ago. The company's library now features over 12,000 books written by 8,000 authors. While Spines does not accept manuscripts fully generated by AI, it utilizes detection technology and offers optional human editing services to improve writing quality.
Operating out of offices in Herzliya and international locations, Spines employs 350 people. The company currently supports English-language titles with translation capabilities into seven languages, and plans to expand support to 20 languages within the next six months.
