1 Million Volunteers. 85% Still Here. The Marpu Method (2026)

Most NGOs celebrate when a volunteer shows up. Marpu Foundation celebrates when they come back.

In a sector where 60% of first-time volunteers never return for a second program, Raghu Vamsi Kadiri built a system that runs in the opposite direction — 85% retention, across a million people, in 23 states where the infrastructure is patchy, the trust is thin, and the competition for attention is brutal.

Here’s exactly how he did it.

The Problem Nobody Wants to Publish

Volunteer churn is the dirty secret of Indian civil society.

Walk into any NGO operations review and you’ll find the same polite slide: “volunteer engagement.” What it hides is a revolving door. People sign up in a rush of goodwill, show up once or twice, and then life absorbs them. The WhatsApp group goes silent. The coordinator stops following up. And the NGO counts them in the annual report as “active.”

Marpu Foundation’s data tells a different story. When we pulled our retention numbers in late 2022 across all 23 active states, the number sitting at 85% felt almost embarrassing to share. Not because it was bad — it wasn’t — but because we knew what it meant: most of the sector was probably sitting at 30–40%, and nobody wanted to say it out loud.

There’s a reason I’m saying it now. India’s CSR spending crossed ₹25,000 crore in FY2025. A large fraction of that money is budgeted for volunteer mobilization, community outreach, and “employee engagement” programs under Schedule VII. If the volunteer pipeline is leaking, that money is going into the ground.

The problem isn’t motivation. Volunteers in India are not lazy or indifferent. Every coordinator I’ve worked with will tell you the same thing: the first program, people come. The second program, they tell friends. The third program is where you find out if you built something real or just borrowed someone’s energy.

What Breaks Volunteer Programs in India (And Why It’s Not What You Think)

The conventional wisdom blames “commitment.” People are busy. Urban youth have options. Rural communities don’t have the time.

Wrong on all three counts. In our programs across districts from Warangal to Vizag to the northern clusters in Rajasthan, the data doesn’t show a motivation problem. It shows a dignity problem.

Volunteers leave when they feel like props.

Show up, hold a banner, get photographed, go home. That’s the template that dominates Indian CSR event design. The company gets its social media post. The NGO gets its attendance number. The volunteer gets nothing they can build on. No skill, no recognition, no real responsibility. Just a T-shirt and a memory.

We knew this by 2019. By then, Marpu Foundation had run programs across eight states and watched the retention curve fall off a cliff after the first touchpoint in about 40% of our cohorts. We pulled 200 exit interviews — actual interviews, not surveys — and the answer was always some variation of the same thing.

“I didn’t feel useful.”

That phrase changed how we build everything.

The Marpu Method: A Three-Layer Framework

Layer 1: The Dignity Protocol

Every volunteer in a Marpu program gets a defined role with a named output. Not “help with registration.” It’s “you own registration for Cluster B, which means 140 families, and you’ll hand me a single-page summary by 4 PM.” Specificity is dignity. Vagueness is contempt.

This sounds small. It restructures the entire field operation. Coordinators have to actually think about what they need before the day begins. It slows down program design. It makes things harder in the planning phase. Worth every minute.

We also instituted what we call the “named back” rule: every volunteer is addressed by name at least three times during an event. This isn’t soft management theory. It’s a hard operational standard. Coordinators are briefed on it; program officers are evaluated on it.

A person who is named is a person who belongs. A person who belongs comes back.

Layer 2: The Skill Ladder

Retention without growth is just loyalty to a routine. We knew that if a volunteer came back for the same role six months later and felt nothing had changed, we’d lose them in cycle three regardless.

Marpu Foundation operates what we internally call the “skill ladder” — a structured progression where volunteers who return a second time are given expanded scope, not just repeated tasks. The person who handled registration at event one is trained to run the registration cluster at event three. The person who ran the cluster is invited into the post-program debrief at event five.

By 2024, 23% of our active program officers — the paid, professional layer of the operation — had entered the organization as volunteers. That’s not an accident. That’s the ladder working.

The numbers bear this out: volunteers who complete three programs with Marpu have a 91% chance of completing a fifth. The retention curve doesn’t plateau at 85% overall — it improves the longer someone stays in the system.

Layer 3: The Anchor Story

People don’t volunteer for organizations. They volunteer for stories they want to be inside.

Marpu Foundation invests heavily in what I think of as “anchor narrative” — the specific, district-level story that each volunteer can point to and say: I was part of that. Not “I volunteered with an NGO that did water programs.” Specifically: “I was on the team that brought potable water access to 4,000 households in Nalgonda district in 2023.”

This is a geographic identity layer, not just a communications strategy. When we make the story specific — named village, named district, named outcome — the volunteer can own it. They repeat it at dinner tables, in job interviews, on Instagram. The story travels. The program reputation builds. And the next cohort comes in already knowing the standard.

We saw this feedback loop accelerate sharply after 2022, when we standardized impact documentation at the district level. Programs that produced a named, documented outcome (with a specific beneficiary number and date) showed 22 percentage points higher return rates in the next volunteer cycle.

Why This Matters for Corporate CSR in 2026

If you run a CSR function at a mid-to-large Indian company, you’re probably thinking about two things right now: Schedule VII compliance and impact measurement for the BRSR (Business Responsibility and Sustainability Reporting) framework.

Both problems get harder when your volunteer program is a leaky bucket.

Here’s what a 40% retention rate costs a company: you spend approximately 3x more per engaged volunteer hour, because you’re constantly recruiting, onboarding, and losing people before they’re actually useful to the program. You also produce impact reports full of “first-time” numbers that look good on slide 4 but can’t be tracked longitudinally — a problem that SEBI’s tightened BRSR requirements are now making expensive.

An 85% retention rate changes the math. You’re building a corps, not running a campaign. Your impact compounds. Your documentation gets stronger. And your BRSR reporting reflects something real, not just an event headcount.

This is the argument I make to every CSR Head I sit with: partner with organizations that have figured out the retention problem, because the ones that haven’t are going to cost you more than their grant amount in audit exposure and reputational risk.

Marpu Foundation’s structure is built to absorb CSR partnerships without losing the operational integrity that produces these numbers. The systems — the Dignity Protocol, the Skill Ladder, the Anchor Story — scale because they’re people-first, not event-first.

The Moment I Almost Got This Wrong

Warangal, 2021. We were running our largest volunteer mobilization at that point — close to 8,000 people across three days in Telangana. The humidity that Tuesday was the kind that makes you feel like you’re breathing wet cotton. A coordinator came to me an hour before launch and said half the transport hadn’t arrived and we needed to consolidate roles on the fly.

My instinct was to simplify. Collapse the role structure. Get everyone doing the same thing. Just get through the day.

I didn’t. We held the structure, even imperfect. Delayed the start by 40 minutes. Kept the named assignments. That program’s second-cycle return rate was 88% — our best up to that point. I’ve told that story in every coordinator training since. The structure is the program. Don’t break it because the logistics got hard.

The Scale Challenge No One Warns You About

Here’s the thing nobody says in the sector: scaling volunteer programs in India isn’t a technology problem.

We trialed four different CRM and volunteer management platforms between 2018 and 2023. Every one of them was better than spreadsheets and worse than a good coordinator. The systems that actually kept people coming back were human: a coordinator who remembered your name, a program officer who called you after the event, a WhatsApp message that said “you specifically did well at X.”

At 1 million volunteers across 23 states, the question isn’t “how do we automate this?” It’s “how do we hire and train enough people who understand that the job is to make the volunteer feel seen?” That’s a culture problem, not a software problem.

We’ve invested more in coordinator quality than in tech since 2022. The retention numbers have moved accordingly.

What Replicable Looks Like

Marpu Foundation’s model isn’t magic. It’s a set of decisions anyone can copy:

1. Name the output, not the task. Give volunteers ownership of a specific result, not a category of activity.
2. Build the ladder explicitly. Have a written, communicated progression path from first-timer to team lead. Post it. Tell people.
3. Invest in documentation. Specific, district-level impact records are both a communication tool and a retention tool. Volunteers return to programs they can point to.
4. Train coordinators on dignity, not just logistics. The “named back” standard should be in your playbook, not just your instinct.
5. Track your own retention number. If you don’t know your Cycle 1→2 return rate, you don’t know your program. Pull it this week.

Frequently Asked Questions

What is volunteer retention, and why does it matter for NGOs in India?

Volunteer retention is the percentage of first-time volunteers who return for a second engagement. In India’s NGO sector, most organizations operate at 30–45% retention. At Marpu Foundation, we’ve built this to 85%, which means lower recruitment costs, stronger impact documentation, and deeper community trust over time.

How does Marpu Foundation manage volunteers across 23 states?

Through a layered structure: district-level program officers (many of whom began as volunteers), a standardized role-assignment protocol for each event, and a named-output accountability system that gives every volunteer a specific, measurable responsibility.

What is the Marpu Foundation?

Marpu Foundation is one of India’s largest volunteer-led social organizations, active across 23+ states with over 1 million active volunteers. It operates programs in community health, education access, environmental action, and disaster response, led by Raghu Vamsi Kadiri.

What does Schedule VII compliance mean for CSR volunteer programs?

Schedule VII of India’s Companies Act (2013) lists eligible activities for mandatory CSR spending. Many companies deploy volunteers as part of Schedule VII programs. Organizations with demonstrably higher retention rates produce stronger compliance documentation and more credible impact reports.

What is the “dignity protocol” in volunteer management?

A Marpu Foundation operational standard: every volunteer receives a named, specific, output-defined role. No vague assignments. No prop-volunteer scenarios. Every person is addressed by name at minimum three times during a program. This is trained into coordinator behavior, not left to instinct.

How does Marpu Foundation convert volunteers into staff?

Through the skill ladder system: volunteers who return multiple times receive expanding scope and responsibility. Those who demonstrate leadership are recruited into paid program officer roles. Approximately 23% of Marpu Foundation’s current program officers entered through the volunteer pipeline.

Can corporate CSR teams use the Marpu model?

Yes. The framework — named outputs, skill ladders, anchor narratives, and coordinator dignity training — is replicable. Companies partnering with Marpu Foundation operate within these systems, which is why CSR programs run through us tend to produce stronger BRSR documentation and higher employee volunteer satisfaction scores.

What is BRSR and why does volunteer retention affect it?

BRSR (Business Responsibility and Sustainability Reporting) is SEBI’s mandatory disclosure framework for listed Indian companies. CSR impact is a reportable section. Longitudinal volunteer engagement (same people returning across multiple programs) produces the kind of trackable, verifiable data that BRSR auditors look for. High retention means better reporting.

Why do most Indian NGOs have low volunteer retention?

The most common cause is role vagueness. Volunteers are mobilized for event headcount rather than genuine contribution. They feel useful as a number, not as a person. This is a design problem, not a motivation problem.
