Software Source Code Ownership: What Founders Should Know

Source code ownership determines who controls your product's future — who can deploy it, hire another team to extend it, sell the company with intact IP, or fork the codebase if a vendor relationship ends. Founders should treat ownership as a business requirement, not a legal footnote.

Custom software built for your business should transfer ownership to you upon payment unless you explicitly license components differently. Contracts should state that deliverables — code, designs, documentation — become your property, with a clear assignment of intellectual property rights.

Clarify what "ownership" includes: Git repository access, credentials, hosting accounts, third-party service registrations, design files, and technical documentation. Code without deployment knowledge or environment configs is difficult to operate.

Open-source and third-party libraries remain under their own licenses. Your vendor should document dependencies and flag copyleft licenses that may affect how you distribute software. Ownership of custom code is separate from compliance with library terms.

Some agencies retain reuse rights to generic components they developed across clients — internal boilerplate, UI kits, or utility libraries. That can be acceptable if your product-specific logic and data models are fully yours. Read reuse clauses carefully.

Escrow is rarely needed for most startup engagements but may matter for enterprise deals or critical infrastructure. More practically, ensure you receive repository access throughout the project, not only at the end.

Nexory defines ownership and handover clearly before work begins — including repository access, documentation, and deployment guidance so you are never locked into a vendor by lack of access.
