Growth & Maintenance Retainer — Kolkata
Most Kolkata businesses outgrow their first agency fast. They launch a website, see a spike, then plateau — because there is no one watching the numbers, fixing the friction points, or pushing the next sprint of improvements. That is the exact problem our Growth and Maintenance Retainer solves. We have been running sprint-based retainers for D2C brands, SaaS startups, and established SMEs across Kolkata and West Bengal since 2024. In that time, we have learned one thing clearly: businesses that grow consistently are not the ones with the best launch — they are the ones with the best ongoing partner. As a DPIIT-recognised startup with a 12-person team in Sector V, Bidhannagar, we are one of the few agencies in Kolkata that operates as a genuine outsourced engineering department rather than a project-based vendor. Your retainer is not a helpdesk ticket queue. It is a monthly sprint with defined deliverables, measurable outcomes, and a direct line to our senior engineers. Our Kolkata retainer clients have seen results like a 41 percent improvement in mobile conversion for a D2C skincare brand, a 33 percent increase in repeat purchase rate for a jewellery label, and 130 hours saved per month through AI automation for a service business. These are not outliers. They are what happens when you treat technology as a continuous investment rather than a one-time cost. Every retainer engagement begins with an audit of your current tech stack. We look at your Shopify store performance, your website Core Web Vitals, your automation gaps, your conversion funnel — and we build a sprint backlog based on what will move the needle fastest. You get a clear roadmap, not a vague promise. Kolkata has over 1.5 million MSMEs, and the shift to digital-first commerce is accelerating. The brands that will win the next three years are the ones investing in continuous improvement today. If you are a founder or growth leader in Kolkata looking for an agency that thinks like an engineering team — not a creative studio — we should talk.

FloraSoul India
100x Revenue growth over 4 years₹1Cr+ From ₹1L to ₹1Cr+ annual revenue+340% Organic traffic increase (Year 1)1.4s Average page load time
FloraSoul India, an Ayurvedic skincare brand founded by Garima Ahuja and Aankush Nagpal, had a vision to bring traditional Indian wellness wisdom to modern consumers. But their digital journey was anything but smooth. Their original website was built on WordPress by two freelancers who took their money and disappeared midway — leaving behind a broken, unusable storefront. The site suffered from constant downtime, painfully slow page loads, and a checkout experience that actively drove customers away. With practically zero revenue from their online channel and growing frustration, FloraSoul was on the verge of abandoning e-commerce altogether. When they reached out to us, they needed more than just a website. They needed a technology partner they could actually trust — one that would deliver on time, on budget, and stick around after launch.
Case studyBaby Forest
₹3Cr+ Annual revenue milestone1.8s Average page load time4.2% E-commerce conversion rate65% Revenue from mobile shoppers
Baby Forest had already built a loyal following among parents who valued Ayurvedic baby care. But their online storefront wasn't keeping up with the brand's premium positioning. The existing website looked dated, loaded slowly on mobile, and wasn't converting the traffic it was getting. In the premium baby care segment, trust is everything. Parents research extensively before putting anything on their child's skin. Every element of the digital experience — from product photography presentation to ingredient transparency — needs to instil confidence. Baby Forest needed a website as premium as their products: elegant, fast, and built to convert discerning parents into repeat customers. With plans to onboard Mira Rajput as brand ambassador, the stakes were even higher. The website had to handle celebrity-driven traffic spikes without breaking a sweat, and the brand's digital identity had to be polished enough to sit alongside a high-profile endorsement.
Case studyZevarly
+280% Organic traffic growth (6 months)+45% Average order value increase+33% Repeat purchase rate1.6s Average page load time
Zevarly, a Kolkata-based fashion jewellery brand run by Mukesh Sethiya from the heart of Burrabazar, had built a loyal offline following through wholesale channels. But the brand had zero digital presence — no online store, no product catalogue, and no way to reach the growing wave of women shopping for jewellery online. The challenge was significant: fashion jewellery is one of the most competitive e-commerce categories in India. Customers can't touch or try on products, so every element of the online experience — from product photography presentation to zoom-enabled detail views — needs to build trust and desire simultaneously. Zevarly's product range spans hundreds of SKUs across gold-plated, silver-plated, and American Diamond collections, including bridal sets that need to feel premium even through a screen. Their competitors were already established on Shopify with polished stores, influencer partnerships, and strong Instagram presences. Zevarly needed more than just a website — they needed a complete digital commerce strategy that could compete from day one, with smart navigation for a large catalogue and pricing strategies that encouraged bulk purchases.

What our clients say
Honest words from people who've been through the process. No stock photos, no made-up companies.
“When two freelancers ran away with our money, we had lost all trust in agencies. Innovatrix didn't just rebuild our store — they rebuilt our confidence. Four years later, we've gone from one lakh to over one crore in revenue. They're not our vendor, they're our technology partner.”
G
Garima Ahuja
Co-founder, FloraSoul India
“We had jewellery but no digital presence. Innovatrix gave us a Shopify store that actually feels like walking into a jewellery showroom. The tiered discounts and WhatsApp integration alone doubled our repeat customers. We went from zero online orders to processing 50+ orders a day within four months.”
M
Mukesh Sethiya
Founder, Zevarly
“Before this system, our team was glued to their phones all day just answering the same questions over and over. Now those hours are back, and our customers actually get faster responses than when we were doing it manually. Rishabh and his team understood our operations deeply before writing a single line of code.”
