About
Rahul D Sarker.
A growth operator, not a marketer.
I build revenue operating systems for growth-stage companies in India, not disconnected marketing services. The work spans strategy, performance marketing, CRM, automation, and attribution, wired into one chain so every rupee of spend ties back to pipeline a CFO would trust.
I speak in CAC, LTV, pipeline, and margin. Not likes, reach, or impressions.
The problem most growth-stage companies have.
Most growth-stage companies between ₹5Cr and ₹100Cr ARR have the same structural problem. They have a marketing team, or three agencies, or both, and none of them are talking to each other. The Meta agency does not know what the Google agency is running. The CRM was set up in a weekend and abandoned. The sales team is tracking deals in WhatsApp groups. Nobody can answer which channel produced which closed deal.
The result is a business spending ₹3L–₹20L per month on marketing with no reliable answer to the most basic question: what is it producing?
This is not a capability problem. It is a structural problem. The solution is not another agency. It is a senior operator who owns the entire chain, strategy, execution, and the systems that connect them, and is accountable to a revenue number, not a channel metric.
That is what a Fractional CMO engagement with me looks like. One person. One chain. One number. No handoff loss between the person who set the strategy and the person running the campaigns. No debate between three agency dashboards about which one drove the sale.
Three agencies, no unified strategy, no one owning the number. Closed by Fractional CMO leadership that ties strategy to execution to systems in one accountable relationship.
A beautiful GTM deck with no operator to implement it. Closed by hands-on performance marketing across Meta, Google, and LinkedIn run by the same person who wrote the plan.
Campaigns running, CRM abandoned, attribution missing. Closed by RevOps and automation that wires spend to pipeline, one attribution chain from GTM through GA4 through CRM to a Looker dashboard the CFO trusts.
What the engagement actually looks like.
Three layers. One operator. Built to compound even after the engagement ends.
Strategy, Fractional CMO leadership
GTM planning, revenue roadmaps, positioning, and team direction. The C-suite marketing perspective most growth-stage companies do not have above a single hire. I join leadership meetings, set the revenue strategy, own the channel mix, and make the budget decisions a CMO would make, on a fractional basis that matches where you are in your growth.
Execution, Performance marketing across every channel
Campaigns built and managed across Meta, Google, LinkedIn, and YouTube, by the same operator who set the strategy. No handoff loss. No translation between a strategist and an execution team who interpret the brief differently. The CAPI is implemented correctly. The campaign structure reflects the sales funnel. The creative brief comes from an understanding of what the algorithm needs, not what looks good in a deck.
Systems, RevOps & automation infrastructure
Attribution, CRM, and automation that tie every rupee of spend to pipeline. The system that keeps working after I leave. A properly implemented CRM where your team actually logs deals. A Looker dashboard where the CEO and CFO read from the same number. A lead nurture sequence that converts cold leads into pipeline without rep intervention. Infrastructure that compounds.
How an engagement runs.
Every engagement follows the same four-phase structure. Tight scope, fixed outcomes, documented handover.
Embed, two-week diagnostic
I spend two weeks inside the business. Every channel, every tool, every number. The goal is to find the one constraint holding back revenue, the broken attribution, the misaligned CRM, the campaign structure running on bad signal. The diagnostic produces a clear brief before a single structural change is made.
Architect, the operating system on paper
GTM plan, channel strategy, attribution design, and RevOps blueprint. Every decision about where to spend, what to build, and how to measure it is agreed in writing before execution begins. The architecture phase prevents the most expensive outcome in marketing: executing the wrong plan very efficiently.
Execute, campaigns live, systems built
Performance campaigns across Meta, Google, and LinkedIn run by the same operator who designed the strategy. CAPI implemented. CRM configured. Automation workflows built. Attribution chain connected. The execution phase is where the architecture becomes measurable, and measurable means improvable.
Hand over, infrastructure that runs without me
CRM workflows documented. Dashboards built. SOPs written. Automation tested. The goal of every engagement is a revenue system that your team can operate, your management can read from, and your next hire can inherit, without me being in the room. The engagement ends. The infrastructure does not.
State the number, or do not make the claim.
A selection of outcomes from client engagements. These are real numbers, not projections.
Industries I work in.
Each industry page is a full breakdown of the specific problems, approach, and deliverables for that vertical, not a generic marketing page with the word "industry" swapped in.
The tools I work in every day.
Not listed to impress. Listed because the depth of knowledge in each tool is where the quality difference shows up in execution.

How the practice was built.
A decade of field work, not credentials, not certifications. The practice was built in client engagements, on WordCamp stages, and in the attribution audit reports that nobody wanted to read but everybody needed.
WordPress Community
A decade of giving back.
I joined the WordPress community in December 2015. Since then, speaking at WordCamps has been a consistent thread running alongside the consulting practice, from small regional events in India to international conferences in the US, Nepal, and across Asia.
The community work is not separate from the professional work. Most of the speaking has been on digital marketing, revenue systems, and growth strategy for WordPress product companies and agencies, the same topics I work on every day, translated for a community of builders who needed practical guidance rather than theoretical frameworks.
Lead organizer of WordCamp Kolkata 2022, the largest Bengali WordPress event to date. WordPress.tv table lead at WordCamp Europe 2021, WordCamp Asia 2023, and WordCamp Asia 2026. Bengali Translation Editor, helping make WordPress accessible to 300M+ Bengali speakers. Published the Simple Customer CRM plugin on WordPress.org.
Who this engagement is right for.
- Growth-stage companies between ₹5Cr and ₹100Cr ARR spending ₹2L+ monthly on marketing and not certain what it is producing.
- Founders and CEOs who have tried one or more agencies and found the channel-level reporting does not translate into business outcomes they can act on.
- Companies where the pipeline review involves reconciling different numbers from different sources, and nobody is confident which number is real.
- Marketing teams that need senior strategic leadership without the commitment of a full-time CMO hire at ₹30L+ per year.
- Businesses where the CRM is technically live but practically unused, and the sales team is still tracking deals in WhatsApp groups and spreadsheets.
- D2C, SaaS, B2B, real estate, and healthcare companies with significant paid media spend and limited attribution between campaign spend and revenue outcomes.
- Businesses preparing for a Series A or B who need clean attribution data, a reliable CRM, and a revenue system that holds up to investor scrutiny.
Not the right fit if:
- You are looking for an agency that runs ads and sends a weekly report. This is not that.
- You are pre-revenue or pre-product-market-fit. Paid advertising amplifies product strength, it cannot substitute for it.
- You want an execution vendor without strategic ownership. I take accountability for the revenue number, which means I need real access to the business: data, team, and decision-making.
- Your business is below ₹1L/month in marketing spend. The infrastructure investment does not yet make economic sense at that scale.
The senior marketing layer you have been missing.
If the revenue chain is broken somewhere between strategy and systems, book a 30-minute diagnostic call. I will tell you where the constraint is before you commit to anything.
