Products Engineered by
StackLab Technologies
In-house products built and owned by StackLab — each solving a specific, narrowly defined operational problem rather than attempting to be a generic platform for everyone.
CardSync
AI-Powered Business Card Scanner
CardSync removes the friction of post-event contact entry entirely. A user photographs a business card, and the app uses AI-powered OCR to extract the contact's name, company, title, phone number and email address automatically. From there, CardSync can automatically send a personalized introductory email and WhatsApp message to the scanned contact.
How CardSync Works
- Photograph a business card with your camera
- Gemini 2.5 Flash AI extracts all contact details via OCR
- Auto-sends personalized intro email + WhatsApp message
- Contact logged to your pipeline in minutes, not days
- AI-generated meeting notes and follow-up reminders (roadmap)
Sigma Cards
NFC Smart Business Card Platform
Sigma Cards reimagines the physical business card as a connected, updatable digital asset. One NFC tap shares your full digital profile — links, contact details, portfolio, social profiles — directly to anyone's smartphone, with underlying information updatable at any time without reprinting a single card.
Three-Phase Roadmap
Core NFC card experience + minimum digital profile functionality. Proves concept for early adopters.
Profile customization, analytics on card taps, account management for paying customers at scale.
Team & enterprise functionality — bulk provisioning, brand customization, CRM integrations.
FarmGo
Agricultural & Grocery Delivery App
FarmGo connects agricultural producers and rural supply chains more directly with end consumers, reducing the layers of intermediation that typically separate farmers from buyers. The mobile-first design is built for users with variable internet connectivity and lower-end devices — a deliberate accessibility decision.
Key Features
- Direct farmer-to-consumer ordering and delivery
- Mobile-first, offline-capable for rural connectivity
- Bilingual interface (Hindi + English)
- Dual-sided onboarding for producers and consumers
- Transparent pricing — removes layers of intermediaries
Our Product Philosophy
Pre-Sell Before We Build
Real payments and committed users are the only reliable signal of product-market fit — not verbal interest or survey responses. Every roadmap is structured around staged validation, not a single large upfront build.
Managed Execution, Not Just Tooling
Where a category already has many self-serve tools, our positioning is built around done-for-you outcomes. The differentiation is the execution layer, not just the feature list.
