Key Takeaways
- Ayr Energy filed a complaint with USITC and Texas courts seeking $1B in damages from Zetwerk
- Zetwerk denies allegations, pointing to its own $100M lawsuit filed against Ayr in October 2025
- The lawsuit arrives just weeks after Zetwerk received SEBI approval for its IPO in India
Zetwerk, the Bengaluru-based manufacturing platform preparing for its stock market debut, now faces a $1 billion lawsuit from US transformer startup Ayr Energy. The complaint, filed with the United States International Trade Commission and a Texas court, accuses Zetwerk of trade secret theft, trademark infringement, and false advertising. Ayr also wants an import ban on Zetwerk's transformers.
The timing is brutal. Just weeks ago, Zetwerk received SEBI approval for an IPO that could raise $450 million through a combination of fresh shares and an offer for sale. Now the company must convince both regulators and investors that this legal fight poses no existential risk.
What does Ayr Energy allege?
Ayr's complaint names Zetwerk Manufacturing Businesses Pvt Ltd and three affiliates: Zetwerk Manufacturing USA Inc, Unimacts Global LLC, and KRYFS Power Components Ltd. The allegations center on a single employee who Ayr claims Zetwerk planted inside the startup under false pretenses.
According to Ayr's filings, this employee accessed proprietary data about its transformer business without authorization, left after six weeks, and then joined Zetwerk to lead a new transformer delivery unit. Ayr claims Zetwerk subsequently began advertising custom transformer capabilities it never possessed and used the Ayr Energy name in online ads.
The charges stack up: trade secret theft, false advertising, trademark infringement, fraud, unfair competition, and participation in breach of fiduciary duty. Beyond damages, Ayr has asked the USITC to investigate and block the import, marketing, and sale of Zetwerk's disputed transformers in the US market.
How has Zetwerk responded?
Zetwerk calls the complaint a retaliatory move. The company noted that Ayr withdrew an earlier claim in California after it "found no traction." In its statement, Zetwerk emphasized that it had sued Ayr first, filing a $100 million lawsuit in Texas in October 2025.
That earlier case accuses Ayr cofounder Anirudh Reddy of incorporating the startup while still serving as a senior Zetwerk executive. Zetwerk alleges Reddy downloaded customer lists, pricing models, and other strategic documents in the months before his resignation in January 2025. The Texas court rejected Ayr's attempt to dismiss that case.
"Our filings characterise this as plain theft," Zetwerk said. "We will prove these allegations in court."
Timeline of the Zetwerk-Ayr dispute
What's at stake for the IPO?
Zetwerk filed confidentially for a public listing in India in March 2026. The proposed IPO reportedly comprises a fresh issue of $300 million and an offer-for-sale component worth up to $150 million. The company has raised over $700 million to date from investors including Peak XV Partners, Lightspeed, and Mars Growth Capital.
Litigation of this scale creates real complications. A billion-dollar damages claim, even if unlikely to succeed in full, forces disclosure in the prospectus. It gives institutional investors a reason to demand a discount. And an import ban, however speculative, threatens actual revenue in the US market.
The transformer business matters. US utilities are investing heavily in grid infrastructure, driven by data center demand and the energy transition. Both Zetwerk and Ayr are chasing the same customers, and the winner of this legal battle may lock up relationships that last decades.
The broader pattern in tech disputes
Trade secret lawsuits between startups and former employees are increasingly common, especially when executives leave to found competitors. The playbook is familiar: confidentiality agreements, forensic audits of downloaded files, and claims that the new venture's suspiciously fast success must have come from stolen data.
What makes this case unusual is the mirror-image allegations. Zetwerk says Ayr's founder stole its data. Ayr says Zetwerk planted a spy. Both companies have filed suits in Texas and both are seeking nine-figure damages. Someone is lying.
Logicity's Take
For fintech and finance teams watching this case, the IPO timing is the critical variable. Zetwerk could delay its offering until the litigation picture clarifies, but that carries its own cost in a market window that may not stay open. More likely, Zetwerk proceeds with enhanced risk disclosures and accepts a valuation haircut. The $1B claim is almost certainly inflated for negotiating leverage, but even a $50M settlement would be material. Watch whether Ayr's USITC complaint gains traction. An actual import ban would shift the balance of power in these negotiations dramatically.
What happens next?
The Texas court will handle Ayr's counterclaims alongside Zetwerk's original suit. The USITC operates on a separate track and typically moves faster than district courts. If the commission agrees to investigate, Zetwerk faces discovery obligations that could complicate its IPO preparations.
Settlement talks are likely, but neither side has signaled willingness to negotiate. Both companies have staked out maximalist positions. Zetwerk, with more capital and a public offering to protect, may have stronger incentives to make this go away. Ayr, as a younger startup, may calculate that prolonged litigation hurts its larger rival more.
