Who I am
I'm Shubhankar Chakraborty, a digital marketer from near Kolkata, India. My work has always been about one thing: bringing in leads and turning them into sales. I have done that work with many agencies – running the campaigns, filling the pipeline and helping the team close the business.
The same problems, agency after agency
Every agency was different, but the problems that cost them leads and sales were the same:
- Leads lost between tools. Leads came from ads, forms, cold email and calls, then lived in spreadsheets, inboxes and separate apps. Nobody could see who had replied or who was next.
- Follow-ups that slipped. Reminders lived in people's heads, so a warm lead often went cold before anyone called back.
- A software bill that grew with every hire. A CRM charged per seat, plus a cold-email tool, a dialler, a proposal tool, a project app and an invoicing app – each with its own subscription.
- Winning the deal was where the trouble started. Proposals were written in documents, projects ran in another app and invoices somewhere else, so details got lost at every handover. GST invoices and monthly retainers were done by hand.
- Client reports built by hand. Every month someone spent hours copying numbers from ad platforms into slides.
So I built the answer to each of them
RoseSpark CRM is built on those pain points. Every lead, email, call and deal sits on one timeline. Sequences and workflows send the follow-ups and set the reminders for you. Proposals are signed online, the won deal becomes a project with client approvals, and invoices – GST invoices and monthly retainers included – come from the same record. Client marketing reports are put together for you. And the price is one price for the business, not a fee for every seat.
It started as a CRM for digital marketing agencies. Along the way it became clear that every agency and service business – studios, consultants, IT firms – runs the same journey: win the client, deliver the work, bill it, report on it. So today RoseSpark CRM is one CRM for any agency or service business.
RoseSpark CRM 1.0 was released on 9 November 2026 after 30 build steps, each tested before release. Version 2 is in development: website tracking with conversion values and source attribution, and a retail and e-commerce module for businesses that sell products.
How it helps
I set up and run every customer's CRM on its own private server. You never touch a server, your data is never mixed with anyone else's, and the price is the same whether you are 3 people or 50. You save on per-user fees and extra tools, follow-ups and invoices run themselves, and your clients get proposals, approvals and reports that look professional.
My promise
Honest pricing with no per-seat surprises. Your data stays yours. A public list of what is built and what is coming. And a personal reply within one business day.
If these problems sound familiar, I would love to show you around. Book a call and I will walk you through it myself.
