About AppArchiTech
Product judgment backed by technical and business depth.
I’m Krishnarup Banerjee, Founder of AppArchiTech, Product Architect, and Fractional CPO.
I help B2B SaaS founders turn business problems into focused product decisions, practical architecture, and working software.
Dual Perspective
Two Perspectives in One Engagement
Product decisions succeed when commercial viability and technical reality are solved together, not in separate silos.
Business Strategy
Understand the business decision.
A product needs a clear customer, a reason to buy, and a workable path to delivering value. I help you clarify those choices and use them to set priorities.
Technical Architecture
Understand the technical consequences.
Product decisions become requirements, data structures, integrations, and operating costs. My architecture and development background helps connect the business intent to what the engineering work will require.
Professional Background
Experience across architecture, development, and B2B consulting.
My background includes more than 15 years of consulting work across software development and digital marketing.
That experience gives me a practical view of how products are conceived, built, explained, and brought to market. At AppArchiTech, I bring those perspectives into the same conversation.
Philosophy
Why AppArchiTech: Keep product intent connected to execution.
I founded AppArchiTech to bring product strategy, architecture, and engineering into a connected engagement.
The work starts with the problem and the people experiencing it. It continues through the decisions that shape the product and into the details that determine whether the software supports the intended outcome.
I take ownership of the agreed work and stay involved in translating direction into concrete next steps.
Working Together
Direct access. Clear responsibilities. Candid recommendations.
AppArchiTech is a founder-led practice. You work directly with me on the agreed scope, with clear expectations about communication, deliverables, and decision ownership.
I explain the reasoning behind recommendations, make important tradeoffs visible, and raise questions when evidence suggests a different direction.
Based in Kolkata, India, I work with a focus on U.S. B2B SaaS founders and their product and technology teams. Collaboration is organized around agreed meeting overlap and documented progress.
Fit
Who the Work Fits
For founders who want a thinking and execution partner. The work is a strong fit when you value direct involvement, are willing to examine assumptions, and want product and technical decisions explained in business terms.
You may be exploring your first SaaS opportunity, building an MVP, introducing AI, or improving a product already in use.
