The Story Behind Marpu Foundation: How a College Idea Became India’s Largest Volunteer-Led Network (2026)

In 2019, a teenage boy in Hyderabad was finishing his BBA at Loyola Academy Secunderabad. He was eighteen, restless, and increasingly unable to make peace with what he was seeing around him. Urban India was changing rapidly. Rural India was being left behind. Climate stress was visible everywhere he travelled. Communities he encountered seemed to have time, energy, and care to contribute, but no structured way to channel it. Corporate India had legal CSR obligations under the Companies Act 2013, but most CSR programmes were being run as transactional spend rather than community engagement.

The teenager’s name was Kadiri Raghu Vamsi. The idea he had was simple in framing but ambitious in scope: a national volunteer-led network that would organise India’s civic energy into structured community impact, working alongside corporate CSR programmes rather than asking only for funding. He gave the network a name: Marpu. The Telugu word for “change.”

Six years later, by April 2026, Marpu Foundation has grown into one of India’s largest volunteer-led social impact networks. The organisation operates across 23+ Indian states, has built partnerships with 250+ corporate organisations including from the Fortune 500, and engages a volunteer network of over one million people. The corporate partner retention rate sits at 85 percent, considerably above the Indian sector average. The Foundation has done all of this without receiving any foreign funding, a deliberate operational choice that has shaped its independence.

This is the story of how that happened. It is written for the student wondering whether a college idea can become a national institution, the founder thinking about what it takes to build something durable, the corporate CSR head curious about Marpu’s origins, the sector observer interested in volunteer-led models, and the journalist or researcher looking for a comprehensive reference.

The story is told honestly. It includes the early difficulties, the operational lessons, the choices that shaped the network, and the constraints that continue to matter. It is not a promotional narrative. It is a working account of how Marpu came to exist and what shaped it.

The Early Years: From a College Idea to a Registered Society (2019-2020)

The Marpu idea took shape in late 2018 and early 2019. Raghu was in the third year of his BBA at Loyola Academy. The thinking had been forming across his school years and the army-family background that shaped his early life. His father had served in the Indian Army. The family had moved across multiple Indian states across his childhood, which gave him an early sense of how varied India is geographically, culturally, and economically.

The specific moment when the idea became serious was a conversation in 2019. Raghu had been discussing his observations with his father. His father said one line that crystallised the next six years of work: do something about what you see, or stop complaining about it.

The line was direct. It was also the right line for a young person who had been describing the problem rather than addressing it.

Within months, Raghu had taken three concrete steps:

1. He named the network Marpu, anchoring it in Telugu language and Indian cultural reference rather than English or generic terminology
2. He registered the entity as a society, choosing the registered-society structure over a private trust or Section 8 company for the governance flexibility it provided
3. He started reaching out to early corporate organisations that might host volunteering activities with their employees

The first corporate partnerships came through cold outreach in 2019 and 2020. The early corporate partners were companies willing to test an unfamiliar model. The deal was straightforward: Marpu would coordinate volunteering activities for the company’s employees in communities the company wanted to engage with. The model worked because it solved a real corporate problem (companies had CSR obligations and engaged employees but limited operational capability) with a real community-side asset (volunteer energy that existed but was not being channelled).

The first year was financially difficult. Marpu did not receive any foreign funding (a deliberate choice that has continued) and the early corporate partnerships were small enough that the operational margins were minimal. Raghu worked through the first year with limited income, relying on family support, occasional consulting, and the small operational coverage from initial partnerships.

The decision to refuse foreign funding has been one of the most consequential choices in Marpu’s history. The reasoning was operational, not ideological. Foreign-funded NGOs in India face specific FCRA compliance requirements, sector scrutiny, and operational constraints that shape programme design. By refusing foreign funding from the start, Marpu retained operational independence to design programmes for Indian corporate partners with Indian regulatory frameworks. The trade-off was lower early-stage funding. The benefit was structural simplicity that has compounded across years.

The Volunteer Engine: The Operational Insight That Powered Growth (2020-2022)

The insight that distinguished Marpu from many other Indian NGOs in this period was operational: India had enormous untapped volunteer energy, and structuring that energy through partnerships rather than activities was what produced scale.

Most Indian NGOs operate on a small full-time staff model, with limited volunteer engagement beyond fundraising events. Marpu inverted this. The full-time team remained small. The volunteer network expanded. The programme model treated volunteers as the operational engine, with the full-time team coordinating and supporting rather than executing.

This worked because of three structural realities in India at that time:

1. Young Indians had time and motivation. College students, early-career professionals, and even mid-career employees wanted ways to contribute that did not require quitting their jobs
2. Corporate India had engaged employees who wanted to volunteer. Most companies had Employee Resource Groups or informal volunteering interest, but no operational coordination
3. Communities had asset gaps that volunteers could meaningfully address. Plantation programmes, education support, healthcare camps, disaster response, water programmes are activities that had genuine community demand and were operationally manageable for trained volunteer groups

By coordinating the three (volunteers, corporate partners hosting them, communities receiving the work) Marpu built a network model that scaled faster than activity-based NGOs typically can.

By 2021 and 2022, Marpu’s network had grown to operate across multiple states. The corporate partner base had grown from initial relationships to dozens of organisations. The volunteer base had grown from hundreds to tens of thousands.

The COVID-19 pandemic affected Marpu’s operations significantly, as it affected the entire Indian NGO sector. Programmes had to be redesigned for distance. Corporate budgets contracted. Volunteer mobilisation became more difficult. The network adapted by shifting toward digital engagement, smaller in-person activities, and a deliberate focus on disaster-response programming. The COVID period was difficult operationally but produced lessons about resilience that continue to shape programme design.

Scaling Across States: From Multi-Hub to National Network (2022-2024)

By 2022, Marpu had moved from a Hyderabad-headquartered organisation to a multi-hub structure operating across several Indian states. The deliberate operational choice was to establish presence in geographies where corporate partners had significant operational footprint (Karnataka, Maharashtra, Telangana, Tamil Nadu, Andhra Pradesh) and to expand from there based on partner-driven demand.

The scaling decisions in this period included:

1. Establishing field teams in additional states rather than coordinating remotely from a single headquarters
2. Building documentation discipline that supported the increasingly demanding compliance environment as the Companies Act CSR framework matured and BRSR Principle 8 disclosure expectations rose
3. Refusing programme types that did not align with the volunteer-led model, even when corporate partners offered funding for them
4. Maintaining the no-foreign-funding position despite multiple opportunities to accept international support
5. Building Schedule VII clause expertise across multiple operational areas (healthcare, education, environment, livelihood, women’s empowerment, rural development)

By 2024, Marpu was operating across 23+ Indian states with established field presence, corporate partner base in the hundreds, and a volunteer network in the hundreds of thousands.

The growth during this period was not linear. There were quarters where partner relationships were renegotiated, programmes that did not produce expected outcomes, geographic expansions that took longer than planned, and operational moments that required difficult internal conversations. The narrative often shared publicly emphasises the growth metrics. The honest version includes the difficult quarters that are not separate from the growth but part of how the growth happened.

The 2025-2026 Phase: From Network to National Institution

The current phase of Marpu’s development is what might be called the institutional phase. The network has grown to 1M+ volunteers, 250+ corporate partners, and 23+ Indian states. The challenge has shifted from growing to operating with the discipline that institutional scale requires.

The operational focus has shifted in five ways:

1. Documentation discipline at audit-grade quality for every project, supporting corporate partners’ annual statutory audit and BRSR Principle 8 disclosure
2. Schedule VII alignment depth across every programme, with primary clause selection documented in MoU and Annual Action Plan references
3. Government partnership expansion through Schedule VII clause ix engagement with public-funded research institutions and clause x rural development alignment with the Aspirational Districts Programme
4. Sector-level reflection contributions through Raghu’s writing, speaking, and SSRN working paper introducing the VFIM (Volunteer-First Implementation Model) and VSAM (Volunteer Sustained Action Model) frameworks for volunteer-led CSR
5. Multi-year programme arcs with corporate partners, moving from annual project cycles to three-and-five-year programme designs that produce stronger sustainability outcomes

The 85 percent corporate partner retention rate is the operational metric Raghu and the Marpu team consider most meaningful. Retention reflects whether partnerships are actually working from the corporate side, not just whether activities are being delivered. Sector average retention in Indian CSR sits at around 30 percent, which means most corporate-NGO relationships do not continue beyond a single project cycle. Marpu’s retention rate reflects the discipline of multi-year orientation, documentation quality, and partnership behaviour that the Foundation has built across years.

The Choices That Shaped Marpu

Across six years of building Marpu, several specific choices have shaped what the organisation became. These choices are worth naming because they were not obvious at the time and they have continued to matter.

1. The Decision to Refuse Foreign Funding

This decision, made in 2019, has produced operational simplicity and Indian regulatory alignment that has compounded across years. Marpu does not hold FCRA registration and does not seek foreign contributions. The trade-off has been lower early-stage funding. The benefit has been structural independence and Indian compliance focus that has supported the Foundation’s broader operational stability.

2. The Decision to Operate Through Volunteers Rather Than Full-Time Staff

This decision has allowed Marpu to scale across 23+ states without proportionally expanding the full-time team. The volunteer model is operationally demanding (coordinating volunteers requires more management discipline than directing employees) but produces scale that activity-based NGO models do not achieve.

3. The Decision to Build Around Corporate Partnership Rather Than Individual Donation

Marpu has not built a significant individual-donation revenue base. The Foundation operates primarily through corporate CSR partnerships under Section 135 of the Companies Act 2013. This focus has produced a coherent revenue model and avoided the fragmentation that mixed donation-and-corporate models often face.

4. The Decision to Document Everything

From the early years, Marpu invested in documentation discipline disproportionate to the Foundation’s stage. Baseline data, activity-level records, beneficiary documentation, photographs, geographic data, Schedule VII alignment, and BRSR-ready outputs were built into the operating model. This investment has compounded across years and is now part of why corporate partners renew at high rates.

5. The Decision to Refuse Programme Types That Did Not Fit

Some corporate partners have offered funding for programmes that did not align with the volunteer-led model. Marpu has refused them. The refusal has occasionally cost relationships in the short term. The benefit has been operational coherence that has produced stronger outcomes across the programmes that do fit.

The Credentials and Recognition That Have Accumulated

Across the six years of Marpu’s development, Raghu’s individual credentials and Marpu’s institutional recognition have accumulated:

1. 2019 Karmaveer Chakra Award for grassroots leadership
2. Champions of Impactful CSR Leader 2025 by ET Edge
3. WEF Global Shaper (Hyderabad Hub) in the World Economic Forum’s youth leadership network
4. UN delegate in multiple international forums
5. Postgraduate Diploma in Urban Environmental Management and Law from NLU Delhi, completed with WWF India
6. Changelooms Fellowship
7. Published author on social entrepreneurship and volunteer-led impact
8. SSRN working paper introducing the VFIM (Volunteer-First Implementation Model) and VSAM (Volunteer Sustained Action Model) frameworks for India-specific CSR

The recognition matters operationally because it supports corporate partners’ due diligence, fellowship committee assessments, and sector credibility. It does not change the day-to-day work, but it shapes the environment in which the work happens.

What Marpu Is Today

As of April 2026, Marpu Foundation operates as:

1. A registered society under Indian law with current CSR-1 registration, 12A registration, and 80G registration with the Income Tax Department
2. A multi-state operational network with field teams across 23+ Indian states
3. A corporate partnership portfolio including 250+ corporate organisations from across Indian and global business, including Fortune 500 partners
4. A volunteer network of over one million people engaged across the year through structured programmes
5. A multi-thematic operation spanning healthcare, education, environment, livelihood, women’s empowerment, rural development, animal welfare, disaster relief, and skill development
6. A documentation-disciplined organisation with audit-ready records that support corporate partner statutory audit, BRSR Principle 8 disclosure, and Board’s Report drafting
7. A non-FCRA, no-foreign-funding entity by deliberate choice
8. An institution shaped by six years of operational learning that continues to evolve

What This Story Is Actually About

If the story has a central insight worth taking away, it is this: durable institutions are built through specific operational choices made early and held across years.

The choices that shaped Marpu (refusing foreign funding, operating through volunteers, focusing on corporate partnerships, documenting everything, refusing programmes that did not fit) were not obviously correct in 2019. They became correct because they were maintained across years through operational pressure that often suggested abandoning them.

The pattern is worth thinking about for anyone building a long-arc organisation. Early choices compound. The discipline of holding choices when they are inconvenient is what separates organisations that grow into institutions from organisations that grow into something less coherent.

For young Indians thinking about building something durable, the lesson from Marpu’s six years is not “do exactly what Marpu did.” Different organisations require different choices. The lesson is to make choices early, hold them across years, and let the compounding produce what it produces.

What Comes Next

The next phase of Marpu’s work continues the institutional development. The 2025-2026 focus areas include deeper Schedule VII clause expertise, stronger BRSR Principle 8 disclosure support for listed corporate partners, expanded Aspirational Districts Programme engagement under clause xii, and continued sector-level reflection through Raghu’s writing and speaking.

The work is ongoing. The growth metrics will continue to develop. The operational discipline will continue to mature. The choices that shaped the early years will continue to be tested by new operational pressures.
