Key Takeaways
- Ayr Energy has filed counterclaims seeking at least $1B in damages and a US import ban on Zetwerk transformers

- The legal battle intensifies as Zetwerk prepares for an IPO reportedly worth $450M in fresh issue and OFS combined
Ayr Energy has fired back at Zetwerk with counterclaims alleging trade secret theft, trademark infringement, and false advertising. The US-based transformer startup is seeking at least $1 billion in damages and wants federal regulators to block imports of Zetwerk's allegedly infringing transformers into the United States.
The escalation comes months after Zetwerk filed a $100 million lawsuit against Ayr and its founder in a Texas court. Both companies compete in the US power equipment market, and both now accuse the other of building a business using stolen confidential information.
Background on the initial lawsuit and IPO context
What is Ayr Energy alleging against Zetwerk?
Ayr filed its complaint before the United States International Trade Commission (USITC) and submitted counterclaims in the ongoing Texas case. The proceedings name Zetwerk Manufacturing Businesses Pvt Ltd alongside three affiliates: Zetwerk Manufacturing USA Inc, Unimacts Global LLC, and KRYFS Power Components Ltd.
According to Ayr's filings, Zetwerk allegedly planted an employee at the startup under false pretenses. This employee allegedly accessed proprietary data about Ayr's transformer business without authorization, departed after six weeks, and then joined Zetwerk to lead a new transformer delivery operation.
Ayr also claims Zetwerk began advertising custom transformer capabilities it did not previously possess. The filings allege Zetwerk used the Ayr Energy name in online advertisements. The accusations span trade secret theft, false advertising, trademark infringement, fraud, unfair competition, and participation in a breach of fiduciary duty.
Beyond damages, Ayr wants the USITC to investigate and block the import, marketing, and sale of the disputed transformers in the US.
How has Zetwerk responded?
Zetwerk dismissed the new complaint as a reaction to its own lawsuit gaining traction. The company said Ayr filed the latest action after withdrawing an earlier claim in California that "found no traction."
“Our filings characterise this as plain theft. We will prove these allegations in court.”
— Zetwerk spokesperson
Zetwerk pointed to its October 2025 lawsuit in Texas, noting the court rejected Ayr's attempt to dismiss that case. The unicorn alleged that Ayr cofounder Anirudh Reddy incorporated the startup while serving as a senior Zetwerk executive and later left with confidential documents.
What does Zetwerk's original lawsuit claim?
Zetwerk Manufacturing USA and Unimacts Global sued Ayr Energy and Reddy in Texas in October 2025. The lawsuit alleged Reddy set up Ayr roughly four months before resigning from Zetwerk in January 2025.
According to Zetwerk's filings, Reddy downloaded customer lists, pricing models, and other strategic documents in the months before his departure. Zetwerk claims Ayr used this information to win contracts from customers already in Zetwerk's sales pipeline.
Zetwerk estimated direct losses of nearly $77 million and alleged Ayr's gains could exceed $100 million. The lawsuit also accused Ayr of hiring former Unimacts executive Chad Stuckey, who allegedly brought confidential information and business relationships to the new company.
| Zetwerk's Claims | Ayr Energy's Claims | |
|---|---|---|
| Damages Sought | $100 million | $1 billion minimum |
| Court/Venue | Texas state court | USITC + Texas counterclaims |
| Core Allegation | Founder stole documents before starting Ayr | Zetwerk planted employee to steal trade secrets |
| Additional Claims | Breach of fiduciary duty, unfair competition | False advertising, trademark infringement, fraud |
| Remedy Sought | Monetary damages | Import ban + damages |
Why does this matter for Zetwerk's IPO?
Zetwerk received SEBI approval for its proposed IPO earlier this month, moving closer to its stock market debut in India. The company filed confidentially for the listing in March 2026. Reports indicate the IPO would include a fresh issue of $300 million and an offer-for-sale component worth up to $150 million.
A billion-dollar lawsuit and potential US import ban create material disclosure obligations. Investors will need to weigh the legal risk against Zetwerk's growth story. The startup has raised over $700 million to date from backers including Peak XV Partners, Lightspeed, and Mars Growth Capital.
Founded in 2018, Zetwerk offers manufacturing services across energy, industrial, aerospace, defense, automotive, and electronics sectors. Ayr, founded in 2024, focuses on transformers, switchgear, and circuit breakers for utilities, renewable energy developers, and industrial customers.
What happens next?
The USITC will decide whether to launch a formal investigation into Ayr's import ban request. Such investigations typically take 12 to 18 months. Meanwhile, the Texas litigation continues, with both parties now asserting claims against each other.
The dispute has become a mirror-image battle: each company accuses the other of the same conduct, down to planted employees and stolen customer lists. Courts will ultimately determine which version holds up, but the timing poses real questions for Zetwerk's public market ambitions.
Logicity's Take
This case illustrates how quickly founder departures can turn into existential legal battles, especially when executives move between direct competitors. For finance teams evaluating pre-IPO companies, the Zetwerk-Ayr dispute highlights the need for thorough due diligence on pending litigation and its potential impact on revenue projections. The $1B claim may be aggressive posturing, but an import ban, even temporary, could materially affect Zetwerk's US market access.
