I founded GrowwStack to help businesses build, launch, and scale complete digital sales systems. We charge our clients ₹0 as an upfront or fixed service fee. Instead, we work through a performance-linked partnership model and earn only from the additional revenue or profits we help generate. Our success is directly tied to our clients’ success. We currently work with three brands across healthcare and clinics, sports equipment, and refrigeration and deep tech. Within three months of operations, these partnerships have generated ₹93 lakh in revenue. GrowwStack provides end-to-end growth solutions, including: • Website and e-commerce development • SEO, GEO, AEO, and organic growth • Lead generation and conversion funnels • Dedicated sales teams for follow-ups and closures • CRM setup and customised sales pipelines • WhatsApp, email, and customer automation • Sales scripts, SOPs, and performance tracking • GA4, GTM, Meta Pixel, and conversion tracking • Revenue, lead, attribution, and sales dashboards • Payment gateway, checkout, catalogue, dealer, and marketplace integrations • Go-to-market strategy, customer support, and post-sale processes We manage the complete customer journey—from attracting leads and handling enquiries to follow-ups, sales closure, payment tracking, and post-sale support. As Founder, I lead business strategy, client acquisition, partnerships, technology development, SEO, CRM, analytics, sales operations, team coordination, and digital expansion. Our goal is to become a complete digital growth and sales partner for businesses seeking measurable, accountable, and scalable revenue growth.

Worked on product development across 4–5 consumer appliance platforms including mixer grinders, hand blenders, nutri blenders, and B&C appliances. Improved product airflow, vibration, acoustic behavior, packaging, and thermal performance through iterative design, testing, and validation. Designed and built a fan testing tunnel as per AMCA 210 with a 3–50 CFM airflow range to compare multiple fan blade geometries and generate fan performance curves. Developed custom test benches and validation setups to benchmark airflow, NVH, and thermal performance against competitor products. Investigated thermal behavior of 400 W motor-driven products as per BIS requirements, identifying hotspots, cooling limitations, and enclosure-level improvement opportunities. Reduced operating temperatures by 15–20°C in Nutri Blender units through vent placement optimization and internal airflow-path redesign. Worked with design, vendor, sourcing, testing, and manufacturing teams to convert prototypes into DFM-compliant production-ready assemblies. Translated technical problems into product improvements by balancing performance, manufacturability, cost, user experience, and reliability.

Pune District, Maharashtra, India

Owned mechanical and thermal design of a solar-powered PCM refrigeration/deep-freezer prototype, including compressor-condenser unit, heat exchangers, airflow paths, refrigerant routing, and enclosure architecture; the prototype I built helped the project secure grant support for further development. Designed PCM-based thermal energy storage systems enabling 45+ hours of battery-free refrigeration holdover during power outages. Contributed to the development of a solar PCM freezer concept that received grant support for further product development and validation. Used CFD simulations, lab testing, and field trials to validate cooling performance, airflow behavior, pull-down time, pressure drop, and thermal holdover. Designed and built a controlled psychrometric test chamber with ~1200 CFM airflow capacity for repeatable testing of Solar AC systems. Collaborated with electrical, controls, sourcing, and vendor teams for component selection, supplier coordination, prototyping, and NPI transition. Applied HVAC and refrigeration principles aligned with ASHRAE and AHRI standards to support system design and performance testing. Worked across product requirement understanding, prototype development, test planning, validation, and design iteration.

Designed refrigeration rack systems, including compressor skids, frames, piping supports, equipment layouts, and mounting interfaces. Performed CFD airflow analysis, enabling removal of one redundant fan and reducing BOM cost by approximately $600 per rack. Improved product cost and performance across 38+ refrigeration rack systems through fan, motor, and airflow optimization. Implemented cut-to-length rack architecture, reducing assembly lead time by approximately 13%. Created manufacturing-ready CAD models and engineering drawings using SolidWorks, GD&T, and DFM principles. Conducted structural analysis for lifting, transportation, installation, and field reliability requirements. Led DFMEA for refrigeration subsystems to identify design, assembly, vibration, and serviceability risks. Collaborated with manufacturing, quality, sourcing, and engineering teams to support NPI and production readiness.

About

I am a product, engineering, and growth professional with experience across hardware product development, consumer products, thermal systems, e-commerce, sales operations, and digital growth. I hold an M.Tech in Thermal Engineering from BITS Pilani, where I graduated with a 9.3 CGPA and a Gold Medal. Over the years, I have worked across mechanical design, new product development, product testing, thermal engineering, analytics, business development, and digital commerce. I am currently building GrowwStack, a performance-based growth agency that helps promising brands create and scale complete digital sales systems. We charge our clients ₹0 as an upfront or fixed service fee. Instead, we work through a performance-linked partnership model and earn only when we create measurable revenue or profit for the businesses we work with. GrowwStack provides complete growth infrastructure, including: • Website and e-commerce development • SEO, GEO, AEO, and organic growth • Lead generation and conversion funnels • Dedicated sales teams for lead handling and closures • CRM setup and sales pipeline management • WhatsApp, email, and follow-up automation • Analytics, attribution, and revenue dashboards • Payment gateway and marketplace integrations • Sales SOPs, customer support, and post-sale processes We currently work with three brands across healthcare and clinics, sports equipment, and refrigeration and deep tech. Across the first three months of operations, we generated ₹93 lakh in revenue for these partner businesses. My role involves identifying high-potential brands, building their digital platforms, designing their sales systems, setting up analytics and CRM infrastructure, managing sales teams, and creating scalable growth strategies. Alongside GrowwStack, I remain deeply interested in product management, technical product development, hardware, AI-enabled products, NPD, consumer products, and deep-tech businesses. I am always looking to partner with strong brands that have good products, market potential, and the ambition to scale.
