a16z-Backed Crypto Startup Entropy Shuts Down After Four Years and Returns $25 Million to Investors

A Quiet Exit From The Crypto Scene

Tux Pacific, the founder of Entropy, has decided to pull the plug on the crypto custody and automation startup after four years of navigating a volatile market.

Despite securing substantial backing from industry giants like Andreessen Horowitz (a16z), the company is winding down operations and returning its remaining capital to investors.

The move follows two rounds of layoffs and several attempts to find a sustainable business model, eventually leading Pacific to conclude that the venture lacked the scale required to succeed in the long term.

Why Did A Twenty Five Million Dollar Venture Shut Down

Entropy entered the market in late 2021 with the ambitious goal of offering a decentralized alternative to established custodians like Coinbase and Fireblocks.

In June 2022, the startup raised $25 million in a seed round led by a16z, with participation from Coinbase Ventures, Dragonfly Capital, and Naval Ravikant.

However, the path to a viable product proved difficult.

Most recently, the team shifted focus toward a crypto automation platform, a blockchain-native version of Zapier, using threshold cryptography and AI to streamline workflows.

Pacific explained on X,

"After an initial feedback request revealed that the business model wasn’t venture scale, I was left with the choice to find a creative way forward or pivot once more."

Rather than burning through the remaining funds on another gamble, the founder chose to exit.

How Hard Was The Journey For Entropy

The startup’s journey was marked by constant evolution, yet it struggled to capture the necessary market fit.

Pacific, an anarchist and self-taught cryptographer with a background at NuCypher, noted that the decision was the result of a grueling four-year stint.

Pacific shared,

"After four hard years working in crypto, I decided that the best I could do has already been done: it was time to close up shop."

While returning capital is relatively rare in the startup world, where many founders choose to pivot until the bank account is empty.

It reflects a pragmatic response to a 2025 funding environment that became increasingly selective, favoring late-stage companies over struggling early-stage projects.

What Is Next For Tux Pacific

In an unexpected twist, Pacific is leaving the digital asset space entirely to pursue a career in pharmaceutical research.

The focus of this new chapter will be on biophysics and organic chemistry, specifically looking at hormone delivery innovations for menopausal and transgender women.

Tux Pacific is a self-taught cryptographer and "market post-left-ish anarchist" who gained prominence as a visible transgender advocate in the technology sector.

Pacific intends to validate research on new drug formulations for estradiol, viewing this transition as a natural evolution of a career dedicated to innovation.

"My time in crypto might be coming to an end, as I feel myself drawn specifically into pharmaceuticals."

To Pacific, "a career is a practice: the goal is not the destination, but the journey of innovation."

Is This A Growing Trend Among Backed Projects

Entropy is not the only high-profile project recently handing back funds.

The decentralized social protocol Farcaster also announced it would return $180 million to investors following a takeover by Neynar.

While the circumstances differ, farcaster is continuing under new management while entropy is dissolving.

Both cases highlight a shift in how venture-backed entities handle capital when original goals are no longer reachable.

Pacific expressed gratitude for the support received during this transition, particularly from a16z general partner Guy Wuollet, describing their guidance as "invaluable" throughout the process of winding down the business.
