📈 Market Timing

The 2025-2026 period offers favorable timing due to maturing WCAG standards, rising global regulations (ADA, European Accessibility Act), increasing corporate focus on inclusive design, and growing legal/compliance demands. Browser extension technology is fully mature while user demand for lightweight, no-setup tools is rising amid digital expansion. Policy emphasis on accessibility and economic incentives for compliance make this an opportune window. Rating: Excellent Timing.

Development and operation costs are low for a free extension distributed via Chrome Web Store. Minimal supply chain or compliance risks since accessibility is the product's core. Strong scalability potential through web store and possible freemium expansion. Key reasons: simple architecture, no heavy backend required, easy maintenance for WCAG updates. Rating: High.

Main segments: Web developers, UX/UI designers, freelance auditors, and digital agencies (tech-focused, 25-45 years old), concentrated in North America, Europe, with growing Asia adoption. TAM for web accessibility tools estimated $1B+, SAM for browser extensions ~$200M, SOM for this free scanner ~$20-50M. Core pain points: time-intensive WCAG audits, lack of clear fix guidance, integration friction. Willingness to pay: moderate; users may upgrade for advanced reporting or automation if offered.
