Bytellex serves Kolkata, West Bengal from Bengaluru — software, web, apps, UI/UX, branding, SEO, and growth. Remote-first, on-site by request.
Kolkata companies building for eastern India — education, regional enterprise, and bilingual products — rarely need a giant IT park vendor. They need an agency that writes clean software and answers the phone. Bytellex serves Kolkata from Bengaluru on IST, with on-site visits when Salt Lake or the central business district stakeholders want a workshop, not another slide deck.
Headquarters stay in Bengaluru. Kolkata work is delivered by the same senior pod — not a junior bench hired after the pitch.
One agency, fourteen ways companies in West Bengal usually start. Each block maps to how people search — company, agency, firm — without a separate thin URL.
Looking for a software development company, agency, or engineering partner in Kolkata? Bytellex designs and builds custom software for education tech, regional enterprise, and publishing-adjacent products. Senior engineers who scope the work also ship it. We operate from Bengaluru and serve Kolkata, West Bengal remotely, with on-site workshops when they change the outcome.
Software development overviewBytellex is a website development and web application team for businesses in Kolkata. We build marketing sites, customer portals, and web apps that load fast and are maintainable — not a theme dumped on cheap hosting. West Bengal companies get the same Next.js and TypeScript bar we use in Bengaluru.
Website and web development overviewNeed an Android, iOS, Flutter, or React Native app development company for Kolkata? We design and engineer mobile products that talk to a real backend, with release discipline and store-ready quality. Delivery is from Bengaluru; Kolkata stakeholders join every sprint review.
Mobile app development overviewBytellex is a UI/UX and product design team serving Kolkata. We research, wireframe, and ship design systems for SaaS, websites, and apps — not slide-only branding. Teams in West Bengal work with the same designers who sit with engineering, so the file that leaves Figma is the file that ships.
UI/UX design overviewBrand strategy, identity, and rebranding for companies in Kolkata: positioning, logo systems, and guidelines your team can actually use. Bytellex is a Bengaluru branding partner for West Bengal businesses that want craft without a 40-person “creative network” markup.
Branding overviewProduct and brand packaging design for Kolkata makers — including FMCG, cosmetics, and premium lines when that is the brief. We connect packaging to the digital storefront so the unboxing and the website tell the same story. Work is led from Bengaluru with reviews that fit West Bengal production calendars.
Packaging design overviewFull-funnel digital marketing for Kolkata: acquisition, landing pages, lifecycle, and measurement. We behave like a growth partner, not a ads-only reseller. West Bengal campaigns are planned against your unit economics, then reported in language a founder can audit.
Digital marketing overviewTechnical, on-page, and content SEO for companies that want to rank in Kolkata and across India. Local modifiers (“in Kolkata”, “in West Bengal”) only work if the site is fast, crawlable, and honest. Bytellex runs SEO from Bengaluru with the same engineering team that can fix the underlying product.
SEO overviewSocial media marketing and management for Kolkata brands — LinkedIn for B2B, Instagram and Meta where the customer actually is. We write strategy and creative that matches the product, then measure it. Not a 30-post calendar with no funnel.
Social media marketing overviewGoogle Ads, Meta Ads, and paid acquisition for Kolkata businesses that care about CAC, not vanity spend. Bytellex sets up tracking, creative tests, and landing pages as one system. West Bengal clients get weekly numbers a CFO can read.
Performance marketing overviewCreative, graphic, and marketing design for Kolkata: decks, campaigns, and visual systems that stay on-brand. We are a small agency, so the people in the kickoff are the people in the files. Useful for West Bengal teams who are tired of freelance scatter.
Creative and graphic design overviewShopify, custom storefronts, and ecommerce SEO for Kolkata brands moving more of their revenue online. We handle catalogue complexity, checkout, and performance — then connect ads and email when growth is the brief. Built in Bengaluru, operated with West Bengal merchandising calendars in mind.
Ecommerce development overviewApplied AI, chatbots, and workflow automation for Kolkata companies that have a real process to improve — not a slide titled “we do GenAI”. Bytellex prototypes against your data and security constraints, then productionises what works. Engineering stays in Bengaluru; West Bengal operators stay in the loop.
AI and automation overviewA software and digital marketing partner for Kolkata: engineering, design, brand, SEO, and growth under one accountable agency. If you searched for a digital agency, IT company, or tech partner in West Bengal, this is the offer — founder-led, remote from Bengaluru, no junior hand-off after the pitch.
Full-service digital agency overviewJudge agencies on who writes the code, how they handle security, and whether the proposal is specific. Bytellex is headquartered in Bengaluru, Karnataka. We serve Kolkata remotely, with on-site workshops when they are useful. We are a founder-led full-stack digital agency — not a marketplace listing. Talk to the people who will ship the work.
No local storefront. Bytellex is headquartered in Bengaluru, Karnataka. We serve Kolkata remotely, with on-site workshops when they are useful. That keeps ownership with a small senior team instead of a shell “branch”.
Price follows scope, not the city name. After a 30-minute discovery call we send a written proposal with timeline and commercials. First response is within 24 hours.
Yes. Engineering, UI/UX, brand, SEO, and growth sit in one agency so the site you launch is the site you can rank and run ads against.
