SofStack is an offshore AI MVP development company for US enterprises and growing businesses. We help American companies validate and launch AI products faster, without the cost and hiring delays of building a full in-house AI team.
Our engineering team is based in India and works on a schedule built around US business hours. You get senior AI engineers, a named delivery lead, US-friendly contracts and full ownership of everything we build.
The AI Delivery Gap for US Companies
US businesses are under pressure to ship AI products, but most face the same constraints:
AI talent is expensive and slow to hire, with long recruiting cycles for ML and LLM engineers
Local agency rates make early-stage AI experiments hard to justify
Internal teams are busy with core product and platform work
Leadership wants proof before committing a full AI budget
SofStack gives you a dedicated AI delivery team that starts within weeks and proves value before you scale.
How We Work Across US Time Zones
We plan a daily overlap window with your team and use the time difference so work progresses while you are offline.
Your time zone | Overlap approach | What you get |
Eastern (ET) | Morning ET overlap window | Daily stand-up and same-day answers |
Central (CT) | Morning CT overlap window | Daily stand-up and async updates |
Mountain (MT) | Early morning MT or scheduled calls | Async updates plus planned meetings |
Pacific (PT) | Evening PT or early morning PT calls | Overnight progress, ready for your morning review |
Sprint demos and steering reviews are always scheduled at a time that suits your stakeholders.
