Most companies start with a Board of Directors that looks a lot like the founding team. Two or three people who trust each other, meet informally, and make decisions quickly. That works well in the early stage. It rarely works once a company has raised outside capital, crossed certain financial thresholds, or added complexity through subsidiaries, ESOPs, or related party dealings. This is when Board Composition stops being a formality and starts becoming a legal requirement.

This blog looks at what the Companies Act 2013 actually requires in terms of Board Structure in India, when those requirements change as a company grows, and how to know if your company has outgrown its founders’ informal approach to Corporate Governance.

What the Law Requires as a Starting Point

Section 149(1) of the Companies Act 2013 sets the baseline for Board Composition under Companies Act 2013. A private company must have at least two directors, a public company at least three, and a One Person Company at least one. The default maximum is fifteen directors, though a company can go beyond that by passing a special resolution in a general meeting.

Every company must also have at least one resident director, meaning a director who has stayed in India for not less than 182 days during the financial year. Section 149(3) originally measured this against the previous calendar year, but the Companies (Amendment) Act, 2017 changed the reference period to the financial year, effective May 2018. This Corporate Governance requirement is easy to overlook for companies with an overseas founder, and it is still commonly misquoted using the older calendar year test.

For most early-stage private companies, this minimum Board of Directors structure is all that is legally required. The complications begin once the company crosses certain thresholds, and Board Composition has to be revisited.

When Board Composition Requirements Change

Company Board Structure requirements scale with size, not company type alone. A few key thresholds to track:

• Independent directors become mandatory for public companies with a paid-up share capital of Rs 10 crore or more, turnover of Rs 100 crore or more, or aggregate outstanding loans, debentures, and deposits exceeding Rs 50 crore. These companies must appoint a minimum of two independent directors.
• Listed public companies must have at least one-third of the total board as independent directors.
• A woman director becomes mandatory for every listed company, and for other public companies with paid-up share capital of Rs 100 crore or more or turnover of Rs 300 crore or more.
• An audit committee becomes necessary once a company crosses the same paid-up capital, turnover, or borrowing thresholds. Under Section 177(2), it must consist of a minimum of three directors, with independent directors forming a majority. A stricter two-thirds independence requirement applies only to listed entities under SEBI’s Listing Obligations and Disclosure Requirements Regulations, not to every public company covered by the baseline Companies Act threshold.

Private companies are not automatically caught by most of these provisions. But many growing private companies convert to public companies, or cross paid-up capital and turnover thresholds while remaining private in structure but public in scale of operations, especially after a Series A or Series B round. Corporate Governance for Private Companies at that stage often needs to catch up with the company’s actual scale well before the law forces the point.

Practical Signs Your Board Structure Needs to Change

Independent of statutory thresholds, there are practical signs a founder-only board is no longer serving the company well. Board Composition under the Act sets the legal floor, but a growing company usually needs more structure sooner than the law demands:

• Investors on the cap table are asking for board seats or observer rights
• Related party transactions have increased and now need independent oversight to withstand scrutiny
• The company is preparing for a fundraise, an ESOP pool, or an eventual public listing
• Decisions that used to take a phone call between two founders now involve legal, financial, and operational trade-offs that benefit from outside expertise
• The company has expanded into new geographies or business lines that founders alone do not have full visibility into

When two or more of these signs are present, it is usually time to review Company Board Structure formally, rather than waiting until a regulatory threshold forces the change.

How to Structure a Company Board for the Next Stage

For companies based in Mumbai and elsewhere in India, structuring a board for growth typically follows a similar sequence. Start by reviewing the Articles of Association to confirm what changes require shareholder approval versus board approval alone. Add directors incrementally, prioritising an independent voice on finance or governance matters before formal thresholds require it. If the company is approaching the independent director thresholds, begin the appointment process early, since due diligence and consent filings under Section 149 take time. Formalise board meeting cadence too, since Section 173 requires a minimum of four board meetings a year with no gap exceeding 120 days, something informal founder boards often skip.

This is how to structure a company board in Mumbai or any other Indian city in a way that holds up under both legal scrutiny and investor diligence.
