India is rapidly accelerating toward becoming a $10 trillion economic powerhouse over the next decade. This leap is being driven by massive public investment in infrastructure, deepening digital penetration, and a structural boom in private manufacturing. Motivated by this historic expansion, investors are aggressively looking to position their portfolios in the sectors that will define the future.
While public markets remain the default, the reality is that true generational wealth is being built behind closed doors. By the time a high-growth company finally lists on the exchanges, much of its valuation premium and structural upside is already fully priced in. To capture outlier returns, smart money and institutional investors are taking their positions early in the unlisted and pre-IPO space—long before the retail frenzy begins.
List of the Top Sectors in India
1. Clean Energy Sector
By 2030, India wants to achieve a massive 500 GW non-fossil fuel capacity target. With India’s renewable energy industry expanding quickly in recent years, the nation has made tremendous progress toward meeting this objective. The energy transition is not just an environmental mandate; it is a matter of national security and economic survival.
The building of ultra-mega solar parks, the deployment of solar rooftop programs, and the push for Green Hydrogen are only a few of the steps the Indian government has started to promote the use of clean energy. In addition, massive Production Linked Incentive (PLI) schemes are aimed at reducing dependency on imports, triggering a gold rush in the domestic renewable manufacturing ecosystem. For unlisted investors, this creates unparalleled opportunities to back Independent Power Producers (IPPs) and Engineering, Procurement, and Construction (EPC) players before they hit the public markets.
Following is a company worth taking a look at in this sector-
- Onix Renewable: A pioneering Gujarat-based company driving innovation across renewable energy, including solar, wind, and Green Hydrogen. With over 16 years of experience and a massive unexecuted order book, Onix operates as an IPP and EPC player. They have successfully launched over 500 MW of projects and are expanding aggressively into solar PV module manufacturing, making their unlisted equity highly coveted for investors looking for a comprehensive, pure-play clean energy asset.
2. Defence Sector
For decades, India was one of the world’s largest importers of defence equipment. That era is fundamentally over. Driven by geopolitical fragmentation and the “Atmanirbhar Bharat” (Self-Reliant India) initiative, the nation is witnessing a massive wave of capital expenditure in domestic defence manufacturing. Import embargoes on hundreds of weapons systems and subsystems have forced localized procurement.
The result is a locked-in, multi-decade order book for Indian defence manufacturers. The government has also launched several initiatives to support the manufacturing industry, ensuring that technology transfer and indigenous R&D are heavily incentivized. While public market defence PSUs currently trade at astronomical valuations, the real alpha is found in the specialized, unlisted supply chain.
Following is a company worth taking a look at in this sector-
- Goodluck Defence and Aerospace: Operating in the highly critical space of specialized forging, precision engineering, and component manufacturing. They supply complex, non-negotiable components required for modern aerospace, naval, and land combat platforms. As defence indigenization accelerates, specialized supply-chain companies like Goodluck are seeing massive order book expansions.
3. AI and Tech Sector
India has long been a significant player in the global IT sector because of its abundant supply of highly qualified workers and a hospitable business climate. However, the ecosystem is rapidly shifting. India is no longer just the IT services back office of the world; it is rapidly transforming into a global hub for Software-as-a-Service (SaaS) and Cloud Infrastructure.
The IT industry in India has recently shifted towards more modern technologies like cloud computing, machine learning, and AI. The digital infrastructure is built, the engineering talent is native, and the shift from services to scalable, high-margin software is accelerating. The unlisted space is teeming with enterprises delivering cloud capabilities and building the critical digital infrastructure needed to optimize operations for large banking, enterprise, and mid-market clients.
Following is a company worth taking a look at in this sector-
- ESDS Software Solution: A leading managed cloud computing and data center services provider in India. With data localization becoming a critical mandate for Indian enterprises and banks, ESDS’s patented cloud technologies (eNlight Cloud) and robust Tier-III data center footprint position it as a major unlisted tech heavyweight operating at the very foundation of India’s digital shift.
4. Fintech Sector
India’s digital public infrastructure including Aadhaar, UPI, and the Account Aggregator framework—has structurally lowered the cost of acquiring and underwriting a customer. The middle class is expanding, and their appetite for credit—both retail and MSME is insatiable.
Traditional legacy banks are often too slow to capture the fringes of this growth, leaving a massive runway for tech-enabled Non-Banking Financial Companies (NBFCs) and digital lending platforms. The Indian government and the Reserve Bank of India (RBI) have created a robust regulatory environment that allows these new-age financial institutions to blend aggressive tech-driven underwriting with high-margin lending products. Buying into these enterprises in the unlisted market means tapping into the core artery of Indian retail consumption before the public market slaps a premium on their valuations.
Following are some of the companies worth taking a look at in this sector-
- HDB Financial Services: An undisputed, unlisted heavyweight backed by HDFC Bank. HDB operates with the agility of a fintech but the massive balance sheet of a legacy bank, gearing up for a highly anticipated IPO to comply with RBI scale-based regulations.
- InCred Holdings: A brilliant example of a new-age NBFC that blends aggressive tech-driven underwriting with high-margin lending products. It has established itself as a premier pre-IPO asset for those looking beyond the traditional banking giants.
5. Healthcare Sector
Due to an ageing population, an increase in chronic illnesses, and a growth in disposable income, India’s demand for healthcare services and medical devices is on a massive rise. The healthcare ecosystem is transitioning from a luxury to a heavily demanded standard.
The Indian government has made several efforts to improve the healthcare industry, including increased healthcare budgets and the PLI scheme for medical devices. The true structural growth is seen in the aggressive expansion of health-tech platforms and indigenous medical device manufacturers. Businesses in these industries are using the increased demand for healthcare products and technology improvements to expand their market share rapidly.
Following are some of the companies worth taking a look at in this sector-
- PharmEasy (API Holdings): A dominant player in India’s digital healthcare revolution. PharmEasy integrates telemedicine, diagnostics, and online pharmacy services into a single digital platform, capitalizing on the massive shift toward e-commerce and accessible digital health solutions.
- S3V Vascular Technologies: Set to become the first Indian company to indigenously design and manufacture a complete suite of neuro-intervention devices (like stents, aspiration catheters, and microcatheters). Backed by prominent investors and government technology boards, S3V is a prime unlisted play on India’s push for self-reliance in high-end, life-saving medical devices.
How you can invest in the future
