Replace intrusive null checks and Preconditions with fluent Java assertions

Replace intrusive null checks and Preconditions with fluent Java assertions targets a $1.2B = 1,000,000 Java-using engineering teams × $1.2K ACV total addressable market with medium saturation and a year-over-year growth rate of 10% YoY (developer tools market growth estimate, e.g., IDC/Gartner industry reports on dev tools and automation adoption).

Key trends driving demand: Shift to developer-first tools — engineering teams prefer lightweight, composable libraries and IDE integrations that improve day-to-day productivity, creating demand for ergonomic assertion tooling.; Open-core business model acceptance — teams adopt free OSS cores and convert to paid enterprise features, making it easier to acquire users and monetize over time.; Increased focus on maintainability and architecture — firms investing in domain-driven design and clean architecture are actively seeking tools that reduce accidental complexity and boilerplate.; Maturing static analysis and code-mod tooling — better tooling lowers cost of automated migrations, enabling faster adoption of enforcement libraries..
