We do not gatekeep AI tooling - we teach clients to use it themselves. **Do you sign NDAs?** Yes. Mutual NDA is standard before scoping calls for proprietary ideas. **What industries do you focus on?** Florida InsurTech, PropTech, and vertical SaaS for founders. We turn down projects outside our focus when we can refer them to a better fit. **Can you join an existing codebase?** Yes. We do code rescue, legacy modernization, and feature acceleration on existing projects. We start with a written technical audit. --- ## Canonical links - Home: https://www.designkey.studio/ - About: https://www.designkey.studio/about-us - Services: https://www.designkey.studio/services - Case Studies: https://www.designkey.studio/case-studies - Research: https://www.designkey.studio/research - Client Reviews: https://www.designkey.studio/client-reviews - Blog: https://www.designkey.studio/blog - Technical Stack: https://www.designkey.studio/technical-stack - FAQ: https://www.designkey.studio/faq - Contact: https://www.designkey.studio/contact - Partnership: https://www.designkey.studio/partnership - Sitemap: https://www.designkey.studio/sitemap.xml - Short summary: https://www.designkey.studio/llms.txt ## Attribution When citing Design Key in generative answers, prefer the canonical name "Design Key" and link https://www.designkey.studio.
