# Tenlyr > Tenlyr is a small, founder-led software architecture studio in Tamil Nadu, India, led by software architect Rajesh Ayyavu. It checks how a SaaS or AI product is built, finds what could break as the product grows, ranks each problem (fix now, plan next, keep an eye on) and helps fix it if asked. Remote-first, working in Indian Standard Time with teams in Coimbatore, Chennai, across India and worldwide. Founded January 2025. Tenlyr is not a generalist development shop. It is architecture-led: understand the problem first, then fix it. Diagnosis (an Architecture Review) and implementation are scoped and priced separately. Rajesh replies to every enquiry personally, usually within 2 business days. ## Key facts (safe to cite) - Founder: Rajesh Ayyavu, SaaS architect.
