Halide co-founder is suing former partner for bringing source code to Apple

A co-founder of Lux Optics, the company behind the Halide iPhone camera application, has initiated legal proceedings against a former partner, alleging financial impropriety and the misappropriation of intellectual property. Ben Sandofsky filed a lawsuit on March 21, 2026, in the California Superior Court of Santa Cruz, targeting Sebastiaan de With, who later joined Apple.

Sandofsky's complaint asserts that de With was terminated from Lux Optics in December 2025. The termination reportedly stemmed from the alleged misuse of company funds, totaling over $150,000, for personal expenditures. Furthermore, the lawsuit claims that de With transferred proprietary source code and confidential company materials to Apple when he commenced employment there in late January 2026.

Background of the Dispute

Prior to de With's departure and subsequent employment, Apple had engaged in discussions to acquire Lux Optics during the summer of 2025. These acquisition talks ultimately did not materialize. Following the unsuccessful negotiations, Apple directly hired de With, a move that now forms a central element of the current legal dispute.

Allegations and Denials

The legal action highlights a significant conflict between the former business partners regarding company assets and intellectual property. The plaintiff, Sandofsky, seeks to establish that de With's actions constituted a breach of his obligations to Lux Optics, particularly concerning the alleged transfer of sensitive company information to a competitor.

Conversely, legal representation for de With has publicly refuted all allegations. His attorney suggested that the inclusion of Apple in the lawsuit is a strategic maneuver designed to exert pressure and attract broader media attention to the case. This counter-argument frames the lawsuit as potentially motivated by factors beyond the direct claims of misconduct.

Legal Implications for Tech Industry

The case underscores the complexities of intellectual property protection and employee mobility within the competitive technology sector. Disputes involving former partners and the alleged transfer of proprietary information to larger corporations are not uncommon, often leading to protracted legal battles over trade secrets and contractual obligations.

Should the allegations be substantiated, the outcome could have implications for how startups protect their intellectual assets when key personnel transition to larger tech firms, especially after failed acquisition attempts. The legal process will now focus on examining the evidence presented by both parties to determine the validity of the financial and intellectual property claims.

Outlook for Lux Optics and Apple

For Lux Optics, the lawsuit represents an effort to safeguard its core technology and financial integrity. For Apple, while not a direct defendant in the initial filing, its involvement as de With's current employer and previous acquisition suitor adds a layer of scrutiny to the proceedings. The resolution of this case will likely set precedents for similar situations in the fast-evolving tech landscape.

Implications

Country Impact: The legal outcome in California could influence intellectual property law interpretations and employee non-compete clauses across the United States, particularly within the tech industry.

Industry Impact: This case highlights the ongoing challenges for technology startups in protecting proprietary information when co-founders or key employees transition to larger, competing firms, potentially impacting future acquisition strategies and talent retention policies.

Market Impact: While direct market impact is limited, the dispute could introduce uncertainty for investors in similar startup ventures, prompting closer examination of internal intellectual property safeguards and co-founder agreements.
