India’s startup ecosystem is attracting growing interest from investors looking to identify promising businesses at an early stage. However, investing in startups requires a different approach from investing in listed companies, where financial statements, historical performance and market prices provide a clearer basis for decisions. For angel investors, evaluating a business often means assessing its potential, the people building it and the competitive advantages it could develop over time.

Rajesh Kumar, a former Indian Revenue Service officer and practising advocate specialising in tax law, brings a combination of legal knowledge, mathematical statistics and experience researching Indian equity markets to his approach to investing. As he explores startup investing, his philosophy centres on disciplined decision-making, careful risk assessment and identifying businesses that can build lasting competitive advantages.

His approach, which he describes as Neti-neti Investing, begins with eliminating weak investment opportunities rather than rushing to select potential winners. This principle shapes how he evaluates founders, business models, valuations and the risks associated with early-stage companies.

Why Investment Decisions Must Begin with Risk

For Rajesh, one of the most important lessons from investing in the secondary market is understanding the difference between volatility and risk. Market prices can fluctuate considerably, but he believes the greater danger is suffering a permanent loss of capital.

He points out that equity investors often experience periods when market declines make safer alternatives, such as fixed deposits, appear more attractive. Investors who are unprepared for these phases may sell at the bottom, converting a temporary decline into a permanent loss.

He also believes that a small number of stocks generate a disproportionate share of overall market wealth. This makes rejection an important part of investment research.

His Neti-neti Investing philosophy follows this principle: instead of searching immediately for the next winner, investors should systematically eliminate businesses that do not meet their criteria.

Rajesh also emphasises the importance of judging decisions by the quality of the process rather than the outcome alone. Since the future is uncertain, even a well-researched investment can fail. A disciplined process, he believes, offers a stronger foundation than the illusion of perfect prediction.

What Attracts Him to Startup Investing

Rajesh sees similarities between investing in listed companies and investing in startups, although the outcomes can be more extreme in the latter.

In both markets, a relatively small number of businesses create a significant proportion of the wealth. He is particularly interested in companies that can build strong competitive advantages before those advantages become obvious to the wider market.

For him, startups represent an early stage in this process. They offer investors an opportunity to identify businesses while their competitive advantages are still developing.

The potential returns also appeal to his investment philosophy. While the loss on an individual startup investment is generally limited to the capital invested, a successful company can generate returns many times greater than the original investment. However, this potential comes with the expectation that many investments may fail.

Rajesh also views startup investing as an opportunity to expand his knowledge. He believes that learning about emerging businesses, their markets and their operating models can itself be valuable to an investor.

Evaluating a Startup: Start by Looking for Reasons to Say No

When assessing a startup for the first time, Rajesh begins by looking for reasons to reject it. Rather than allowing an attractive pitch or a promising idea to drive the decision, he focuses on a set of fundamental questions.

First, he examines whether the startup is addressing a real and significant customer problem. He wants to understand whether customers already pay to solve that problem and whether the market is large enough to support a meaningful business.

The next question concerns competitive advantage. Rajesh looks for the beginnings of a structural advantage, such as switching costs, network effects, cost advantages or capabilities that competitors would find difficult to replicate.

He acknowledges that an early-stage company may not yet have a fully developed moat. However, the business should have a structure through which such an advantage can emerge, and its management should understand why competitive advantage matters.

He also examines the business’s economics, including customer acquisition costs, customer retention, spending over time and its dependence on fresh capital. A company that continually requires additional funding without improving its economics raises concerns for him.

Founders and investment terms are also part of the evaluation. His approach is built around the belief that a serious weakness in any essential area can undermine an otherwise attractive opportunity.

Why Founder Credibility Matters More Than a Promising Idea

Rajesh places the founding team ahead of the business idea when evaluating an investment. In his view, ideas can change as startups learn from customers and adapt to market conditions. An honest and capable team may find a better direction, while a weak team can undermine even a strong business idea.

He considers honesty a non-negotiable requirement. To assess a founder’s credibility, he compares the founder’s claims with information from customers, former colleagues and previous investors. He also pays attention to how founders discuss failures and whether their numbers remain consistent across conversations.

Related-party transactions and the treatment of employees and minority shareholders are additional areas he examines.

When evaluating a founder’s vision, Rajesh looks for specific answers rather than broad ambitions. A founder should be able to explain what the business could look like in five years, what needs to go right and what evidence would show that the original assumptions were incorrect.

Execution, meanwhile, must be supported by evidence. Products delivered, customers acquired and milestones achieved with the available capital help him assess whether a founder can translate plans into results.

For startups with limited operating histories, he considers small promises kept to be an important indicator of credibility.

Making Investment Decisions When Financial Data Is Limited

Unlike listed companies, early-stage startups may not have extensive financial histories. Rajesh approaches this uncertainty by assessing evidence as it emerges and updating his investment thesis accordingly.

He looks for indicators such as customers renewing their subscriptions or contracts, repeat revenue increasing, customer acquisition costs declining and the business extending its financial runway without increasing its spending.

Pricing is another useful signal. If a company can increase prices without facing significant customer resistance, it may indicate that customers value its offering.

Rajesh also monitors how a startup’s competitive position develops over time. Changes in customer or distributor numbers, the cost of acquiring customers and the company’s bargaining power can help indicate whether its advantage is strengthening.

He believes the investment decision should evolve as new information becomes available. Where evidence is limited, he prefers smaller initial investments and staged capital allocation, committing more only when subsequent milestones support the original thesis.

Valuation Requires Realistic Expectations

Startup valuations can be difficult to assess because there is no established market price for a company’s shares. Rajesh accepts that valuation at this stage involves considerable uncertainty and cautions against placing too much confidence in highly precise financial models.

His approach is to work backwards from the potential outcome. He considers what the company would need to become, how long that transformation might take and what return an investor could receive after accounting for dilution in future funding rounds.

He then assesses how likely that outcome is, rather than relying solely on the projections presented by the founder.

This approach connects valuation directly with risk and expected returns. A promising business may still be an unattractive investment if the price assumes that nearly everything will go according to plan.

For Rajesh, being approximately right about a company’s prospects is more useful than creating a model that appears precise but rests on uncertain assumptions.

Managing Risk in an Asset Class Where Many Startups May Fail

Rajesh believes investors should enter startup investing with the expectation that most individual investments may not succeed. Consequently, the capital allocated to this asset class should be money they can afford to lose entirely without affecting their financial stability.

He views startup investments as a small part of an overall portfolio rather than its core. Within that allocation, he prefers to begin with modest investments and retain capital for companies that demonstrate stronger evidence over time.

Diversification also matters because successful startups are difficult to identify in advance. Investing across a reasonable number of companies can help account for the uneven distribution of returns.

He refers to the Kelly criterion, a framework for determining capital allocation based on an investor’s estimated advantage. However, he treats it as a ceiling rather than a target, particularly when an investor’s assessment of their own advantage remains uncertain.

The central principle is to size investments according to the risks involved, rather than allowing the excitement surrounding a promising company to dictate the amount invested.

Red Flags That Can End an Investment Discussion

For Rajesh, dishonesty is sufficient reason to walk away from a startup, regardless of how attractive its business model might appear.

Inconsistent financial figures, unverifiable claims and different versions of the same story are warning signs. He also looks for unclear ownership structures, related-party transactions and money moving between a founder’s other businesses and the startup.

A founder’s reluctance to share information or answer difficult questions can raise further concerns. Other red flags include a business that continually needs more capital without improving its unit economics, a founding team experiencing serious conflict and a valuation that assumes an unrealistically favourable outcome.

He also cautions against making investment decisions under pressure. Urgency and fear of missing out can cause investors to skip essential checks.

His philosophy is straightforward: a serious red flag should not be dismissed simply because the company performs well on other measures.

How Angel Investing Differs from Listed Equities

One of the biggest differences between listed equities and startup investments is liquidity.

Listed shares can generally be sold through the market at an observable price. Startup investments, by contrast, may remain locked in for years, with no straightforward way to exit. Even when an exit becomes possible, there is no guarantee that it will happen or deliver the expected returns.

Rajesh notes that startup outcomes can be close to binary. Many investments may fail, making the returns from a relatively small number of successful companies especially important to the overall portfolio.

The absence of daily market prices also changes investor behaviour. It can reduce the temptation to react to short-term price movements, but it removes an immediate source of feedback about the investment thesis.

To address this, Rajesh believes investors should document their original assumptions and review them against the company’s progress at important milestones.

The Due Diligence He Would Prioritise

Before making his first startup investment, Rajesh would seek a comprehensive understanding of the company’s legal, financial and commercial position.

Legal due diligence would include reviewing shareholder agreements, the capitalisation table, shareholder rights, intellectual property ownership, regulatory compliance and related-party arrangements. Although his background as an advocate provides relevant knowledge, he would still seek an independent review of the documents.

Financial due diligence would involve examining the company’s accounts, cash burn, runway, unit economics and tax position with the help of a chartered accountant.

He would also speak with customers, former employees and earlier investors to understand the business beyond the information presented by its founders. The participation of a credible lead investor could provide an additional source of confidence, although it would not replace his own assessment.

For Rajesh, due diligence is not simply a procedural requirement. It is an essential part of protecting capital and testing whether the investment thesis is supported by evidence.

India’s Angel Investing Ecosystem: Opportunities Ahead

Rajesh expects India’s startup investment ecosystem to become larger, more formalised and more investable over the next five to ten years. He sees opportunities for organised angel networks and investment funds to participate in a broader range of businesses, including those emerging beyond the country’s largest cities.

He also points to developments in India’s startup policy and investment environment, including the removal of angel tax and changes to the regulatory framework for angel funds, as part of the evolving landscape.

However, he cautions that a more accessible funding environment does not automatically improve the prospects of individual startups. Greater availability of capital makes disciplined evaluation even more important.

As he enters the space, Rajesh plans to apply the same principles that guide his approach to listed equities: reject unsuitable opportunities early, begin with smaller investments, increase exposure only when the evidence strengthens and continue learning from experience.

He also sees value in co-investing with experienced investors to understand the asset class before committing larger amounts of capital.

Building Wealth Through Discipline, Not Prediction

Rajesh Kumar’s approach to angel investing reflects a broader belief that successful investment decisions depend less on predicting the future and more on evaluating evidence, managing uncertainty and avoiding preventable mistakes.

His Neti-neti Investing philosophy places rejection at the centre of the process, while his emphasis on founder credibility, competitive advantage, realistic valuations and careful capital allocation offers a framework for assessing early-stage businesses.

As India’s startup ecosystem continues to expand, these principles underline an important distinction: identifying a promising company is only one part of investing. Understanding what could go wrong, deciding how much capital to risk and remaining disciplined when outcomes are uncertain are equally important.

For Rajesh, entering angel investing is an extension of his existing investment philosophy, with a greater emphasis on patience, staged commitments and learning as businesses develop.
