About Sigma Tech

Empowering Small Businesses with AI Technology

Sigma Tech Communications LLC was founded with a clear mission: to make advanced AI phone technology accessible to every small business, regardless of size or budget. Based in the Virginia, DC, and Maryland area, we specialize in serving the Korean-American business community while welcoming entrepreneurs from all backgrounds.

Our Mission

Small businesses are the backbone of our communities. Yet many struggle with a simple problem: answering every customer call. Missed calls mean missed revenue, lost customers, and opportunities that never come back.

We built Sigma Tech to solve this problem. Our AI phone receptionist answers every call 24/7, books appointments, answers questions, and sends instant notifications — all for a fraction of the cost of hiring additional staff.

As a Korean-American owned company, we take special pride in serving our community. We offer bilingual support in English and Korean, ensuring every caller receives a warm, professional experience.
