AI-powered hybrid publisher Spines secured $64 million in new capital as its revenue run rate hit $50 million, according to Refresh Miami and Fortune.

What Happened: $29M Equity Plus $35M Debt

Spines, a Boynton Beach-based AI-powered publishing startup, announced Monday that it has secured $64 million in new growth capital, according to Refresh Miami.

The financing consists of a $29 million Series A-1 equity round led by Zeev Ventures, with participation from Aleph, NordStar, M-Fund and LionTree, alongside angel investor Dan Senor, plus a $35 million non-dilutive financing facility from Twelve, the credit-focused investment firm.

Fortune reports the company declined to disclose its valuation after the funding. The company says its annual revenue run rate has reached $50 million, representing 400% year-over-year growth, with more than 8,000 American authors published so far and roughly 400 new authors joining each month.

Why It Matters: A Broken Process Rebuilt in Weeks

The surprise is the scale of appetite for an alternative to traditional publishing, where Refresh Miami notes authors face lengthy approval processes, high costs and limited control.

The platform uses specialized AI agents to handle proofreading, cover design, formatting, distribution to more than 100 channels including Amazon, and royalty management, with human editors and designers still in the loop.

"We don't believe the future of publishing is AI writing books. We believe the future is AI giving authors superpowers," Niv said in the company's announcement.

The Evidence: Authors Pay Upfront, Keep 80%

Fortune reports that Spines operates as a hybrid publisher, charging authors upfront fees of about $3,000 to $20,000, with most choosing a mid-tier bundle costing $5,000 to $7,000.

Authors now keep 80% of net royalties, up from 70%, and the company reports royalties monthly rather than the twice-yearly statements common in the industry. Niv told Fortune that Spines only publishes books "100% written by humans" and uses software to weed out AI-generated manuscripts.

The Stakes: Expansion and a Possible Big Five Deal

Fortune reports that Spines will use the equity to build out its product and expand beyond the U.S. into other English-speaking markets including the U.K., Canada and Australia, with Niv aiming for 200% to 300% annual growth.

Niv also told Fortune the company is in early talks with one of the Big Five U.S. publishers about a partnership in which Spines and its AI agents would help run that publishing house's services.

"Spines has all the ingredients to become the category leader in the next generation of publishing," Oren Zeev said, per Fortune.

Refresh Miami quotes Niv framing the mission as changing who gets to become a published author: "For most of publishing history, gatekeepers decided who was worthy of becoming an author and which stories deserved to reach the world."
