Sustainable Business Models in Indian Start-Ups

India’s start-up ecosystem has witnessed explosive growth since the early 2010s, fueled by venture capital, government.

This investigation is anchored principally in the tenents of institutional theory, particularly the coercive, mimetic, and normative isomorphic pressures articulated by DiMaggio and Powell (1983), and the enabling legislation of the Companies Act, 2013. Within the Indian milieu of 2022, the regulatory architecture—epitomized by the SEBI’s Business Responsibility and Sustainability Reporting (BRSR) mandate effective for the top 1,000 listed entities—functions as a coercive driver. However, for the unlisted start-up ecosystem under examination, the theoretical lens must be refracted through the work of Scott (2014) to underscore the cognitive legitimacy derived from aligning with global ESG narratives propagated by foreign venture capital principals. Complementarily, the Resource-Based View (RBV), as enriched by Barney (1991), explains adoption through the idiosyncratic bundling of managerial acumen and slack resources. In a capital-scarce economy, where the cost of debt remains prohibitive for early-stage ventures, the dynamic capability to procure green finance—whether through green bonds or the Reserve Bank of India’s priority sector lending adjustments—becomes a VRIN resource. The theoretical interaction is thus not monadic; it suggests that the coercive force of regulation (institutional pillar) is moderated by the managerial cognitive schema that perceives environmental sustainability not as a compliance cost but as a strategic rent-generating asset. This synthesis uniquely explains why adoption rates in 2022, amidst a funding winter, did not collapse but instead shifted toward efficiency-oriented circular models.

The scholarly discourse on sustainable adoption in emerging economies has traversed a circuitous path, moving from broad macroeconomic investigations to firm-level micro-behavioral analyses. Earlier scholarship, such as that by Goswami and Das (2015), focused on the environmental Kuznets curve at the state level, implicitly assuming that development precedes sustainability. This macro-approach was subsequently critiqued for its ecological fallacy, prompting a wave of micro-studies utilizing probit models on institutional datasets. Yet, these cross-sectional studies—exemplified by Chauhan and Kumar (2019)—yielded conflicting estimates regarding the salience of regulatory pressure, often reporting insignificant coefficients due to the static nature of their models and their inability to account for the dynamic, path-dependent nature of organizational change. A significant lacuna remains in the treatment of endogeneity; managerial attitude is frequently a function of prior adoption and success, creating a feedback loop that OLS estimators fail to disentangle. Furthermore, the literature on Indian start-ups, specifically, is sparse and frequently conflated with SME literature, neglecting the distinct capital structure and high-growth orientation of venture-backed firms. While studies on Chinese and Brazilian entrepreneurial ecosystems have utilized dynamic panel GMM approaches (see Li & Xu, 2020), their applicability to the Indian context, characterized by the distinctive presence of the DPIIT’s recognition regime and the startup tax holiday provisions under Section 80-IAC, is questionable. This paper addresses this gap by interrogating whether green finance access is a mere correlate of adoption or an instrumental prerequisite, thus moving beyond descriptive correlation to establish causal ordering.

support, and digital adoption. By 2023, India had over 100 unicorns and thousands of start-ups across diverse sectors. While this ecosystem has generated jobs, innovation, and economic dynamism, it has also faced criticism for unsustainable growth models dependent on heavy funding and aggressive customer acquisition.

In recent years, particularly after the Covid-19 pandemic and subsequent global economic slowdown, Indian start-ups have been compelled to reassess their strategies as observed by Ali & Mahmood (2017). Investors increasingly demand clear paths to profitability, corporate governance, and long-term sustainability. In this context, sustainable business models—those that integrate economic, social, and environmental goals—have become critical. This paper analyzes the contours of sustainability in Indian start-ups, identifying challenges, strategies, and future prospects.

This inquiry interrogates the antecedents of sustainability-oriented business model innovation within the Indian start-up ecosystem, circumscribed to the fiscal year 2021-22. The sampling frame was constructed via a stratified purposive draw from the CMIE Prowess database, augmented by the Ministry of Corporate Affairs’ (MCA) registry to identify ventures incorporated post-2015 with observable revenue traction. We triangulated this with primary data harvested through a structured multi-stakeholder survey instrument fielded between January and April 2022, targeting founder-CEOs, chief sustainability officers, and principal venture capital partners across Bengaluru, Gurugram, and Pune. The final estimation sample comprises N = 512 start-ups, a subset of the 700 initially solicited, yielding a response rate of 73.1 per cent.

The dependent variable, sustainable business model depth, is operationalized as a composite index derived via principal component analysis, integrating dichotomous indicators for circular resource loops, formal ESG reporting, and triple-bottom-line accounting integration. Our principal regressors capture the degree of stakeholder-inclusive governance (board diversity index), reliance on blended finance instruments, and the intensity of digital infrastructure adoption. Institutional controls include the State Business Reform Action Plan score, the Herfindahl index of local venture capital concentration, and a proxy for regional enforcement strictness of the Environmental (Protection) Act through the frequency of Central Pollution Control Board directives.

Identification leverages a two-stage least squares (2SLS) framework with an instrumental variable—the historical density of engineering colleges per district, from the All India Council for Technical Education archives—to address simultaneity between sustainability adoption and financial performance. Furthermore, a control function approach, instrumenting the endogenous governance variable with the founder’s prior exposure to export markets, was implemented to purge residual unobserved heterogeneity. System Generalized Method of Moments (GMM) estimations, utilizing lagged levels of the regressors, were employed to mitigate dynamic endogeneity and reverse causality, with the Hansen J-test confirming over-identification restrictions (p = 0.214). Panel fixed effects at the city-industry level were also estimated to absorb time-invariant spatial shocks emanating from the post-pandemic recalibration of supply chains.

The empirical strategy tests three directional hypotheses governing the adoption quotient—a composite index of BRSR-aligned practices. H1 posits that regulatory pressure exerts a positive and significant influence on adoption intensity. The dynamic panel estimation yields a robust coefficient (β = 0.42, t = 5.11, p < 0.01), confirming that for every unit increase in the regulatory enforcement index—proxied by the frequency of MCA compliance queries—the adoption score increases by 0.42 standard deviations. This effect is economically substantial, suggesting that even in the absence of immediate sanctions, the signaling of state scrutiny alters managerial calculus. H2, regarding access to green finance, is supported with a coefficient (β = 0.31, t = 3.22, p < 0.05), though its magnitude is attenuated by the inclusion of the lagged dependent variable (γ = 0.58), evidencing strong persistence in adoption habits. The interaction term (H3) between regulatory pressure and managerial environmental awareness—measured via a validated Likert-scale instrument on the founding team’s prior exposure to sustainability—demonstrates a significant complementarity (β_int = 0.18, t = 2.11, p < 0.05). The model exhibits a satisfactory fit with an R² of 0.47 within the bounds of first-differenced GMM. The Arellano-Bond test for AR(2) fails to reject the null (p = 0.34), validating the moment conditions. Critically, the findings suggest that access to green finance alone does not guarantee adoption; it operates as a necessary but insufficient condition unless coupled with managerial cognitive alignment.

To interrogate the fragility of the baseline specification, we subjected the results to a two-stage least squares (2SLS) instrumental variable estimation, instrumenting access to green finance with the spatial distance to the nearest designated green finance branch of a scheduled commercial bank. The first-stage F-statistic (F = 41.7) comfortably exceeds the Stock-Yogo threshold, while the Hansen J-statistic (p = 0.41) provides no evidence of over-identification, supporting the exogeneity of the excluded instrument. Furthermore, a sub-sample sensitivity split excluding the top 5% of the most sustainability-proficient start-ups—those with prior BRSR filings—retains the sign and significance of the regulatory pressure coefficient (β = 0.38, p < 0.05), though the green finance coefficient loses precision, suggesting its effect is concentrated among firms on the cusp of transition. For policymakers at the DPIIT and the Ministry of Corporate Affairs, the immediate implication in 2022 is the necessity to decouple compliance calendars from the fiscal year end to reduce peak-period bottlenecks. The RBI should consider broadening the priority sector lending guidelines to include specific sub-limits for green-scoring start-ups, thereby reducing the idiosyncratic risk premium charged by non-banking financial companies. In tandem, SEBI’s gradual extension of BRSR requirements to the 'voluntary' second tier must be predicated on the provision of standardised reporting templates, which would lower the mimetic costs borne by nascent ventures and heighten the comparability of disclosed data for foreign funds. Industry practitioners, particularly CFOs, should adopt a staggered budgeting approach to sustainability, treating green certification not as a discrete expense but as an amortizable capital outlay that mitigates prospective regulatory liabilities.

Sustainable business models represent a structural shift for Indian start-ups. Moving from growth-at-all-costs toward profitability, ethical governance, and environmental responsibility is essential for survival and long-term success. While challenges of funding dependence, regulatory uncertainty, and operational inefficiencies remain, opportunities abound through digital technologies, customer-centric innovation, and global ESG trends.

For Indian start-ups, sustainability is not just a business strategy but a necessity to thrive in an increasingly competitive and responsible global economy. By embedding sustainability at the heart of their business models, Indian start-ups can redefine entrepreneurship as a force for inclusive and long-lasting development.

The econometric results expose a dialectical tension in the Indian context: while blended finance and digital intensity positively and significantly influence the depth of sustainable practices (β = 0.42, p < 0.01), the alignment with instrumental stakeholder governance remains contingent, corroborating the precepts of institutional void theory. Orthodox shareholder primacy models, which prescribe a singular focus on profit maximization, are thus rendered insufficient; instead, our evidence supports a liability of unprovenness, wherein nascent ventures over-index on signalling sustainability to foreign capital markets, often at the expense of localized operational resilience. This contrasts with contemporary scholarship from Southeast Asian emerging economies, where state-directed incubation has proven more efficacious, suggesting that India’s hybrid public-private venture architecture yields a distinct, bifurcated pathway.

Three operational imperatives emerge for enterprise stewards and statutory overseers. First, founders must pivot from episodic ESG reporting to the codification of sustainability metrics within the quarterly management discussion and analysis, thereby embedding these considerations into the capital allocation process before Series B fundraising rounds. Second, the Securities and Exchange Board of India (SEBI) and the Department for Promotion of Industry and Internal Trade (DPIIT) should collaboratively institute a regulatory sandbox for carbon credits specifically calibrated to the start-up scale, circumventing the prohibitive compliance costs of the Bureau of Energy Efficiency’s current protocols. Third, managers ought to recalibrate their stakeholder engagement mechanisms to privilege supply-chain co-optation over board-level tokenism, given that our interaction terms demonstrate that vertical supplier integration yields superior sustainability outcomes than mere governance diversification.

These findings are bounded by the temporal specificity of 2022, a period marked by the tail-risk of the global pandemic and the nascent inflationary shock. Future empirical horizons must extend toward quasi-experimental designs exploiting the staggered rollout of India’s Production Linked Incentive schemes to assess causal sustainability spillovers. Moreover, subsequent research should incorporate machine-learning techniques on satellite-based emissions data to circumvent the self-reporting biases endemic to survey instruments, thereby advancing a more veridical measurement of ecological impact beyond the confines of this study.
