Convertible notes and debentures for Indian startups: founder checklist
Compare startup convertible notes and convertible debentures at a high level, identify conversion and repayment terms, model dilution, and flag company-law and foreign-investment questions before accepting funds.
In this guide
What does a convertible startup investment do?
A convertible instrument begins under agreed debt or security terms and may convert into shares when specified events occur. The label alone does not tell you the legal route, repayment rights, investor protections or final ownership. Indian company law, the company's status and documents, investor residency and current foreign-investment rules can all matter; obtain transaction-specific advice before accepting money.
Do not treat every convertible as the same instrument
A convertible note, convertible debenture and convertible preference share can have different legal character, repayment features, conversion rules and approvals. A US-style SAFE template may not map cleanly to an Indian company's available instruments. Ask counsel to name the instrument precisely and explain the statute, rules and filings that apply.
Write down the conversion event and formula
Identify what triggers conversion, the price or valuation formula, any cap or discount, interest treatment, the share class issued and how fractional shares or a changed round are handled. Define what happens if the trigger never occurs, the company sells, a deadline arrives or another financing has different terms.
Check repayment, maturity, security and default provisions
Confirm whether the holder can demand repayment, what maturity means, whether interest accrues, whether security or guarantees are offered and what counts as default. Model the cash impact if conversion does not happen. A convertible can create a debt obligation before any equity is issued, so do not rely on optimistic conversion assumptions.

How do founders assess conversion and dilution?
Model at least three outcomes
Calculate what happens if the next priced round closes as planned, closes at a lower valuation, or does not happen before maturity. Include principal, interest, cap, discount, pool changes, share class and any other converting instruments. Ask the investor to verify the same assumptions rather than comparing incompatible spreadsheets.
Check whether conversion is automatic or requires another step
Read the trigger carefully: a financing size threshold, holder election, company action or specified date can lead to different results. Confirm what notices, approvals, filings, payment or allotment process must follow. Do not assume the words 'converts at the next round' answer every timing and eligibility question.
Compare the instrument with priced equity and ordinary debt
A convertible may defer a valuation negotiation but can add uncertainty about later ownership and repayment. Compare it with a priced share issue, a loan and the company's cash runway. Include legal, accounting and administration costs as well as the headline amount and dilution.
What changes when an investor is resident outside India?
Get foreign-investment advice before signing or receiving funds
A non-resident investment can bring Foreign Exchange Management Act and Non-Debt Instrument Rules conditions, sector or route checks, permitted pricing, payment and reporting steps. The applicable route depends on the actual instrument, investor, company and sector. Ask an Indian cross-border investment lawyer and the authorised dealer bank to confirm the current process in writing.
Confirm the startup and instrument qualify for the intended route
Do not assume that a company called a startup, a DPIIT recognition certificate or an investor's overseas status automatically makes a particular note available. Check the legal definition, recognition or other eligibility condition, amount, tenure, conversion and sector rules that apply on the transaction date.
Track closing documents, funds and required filings
Agree who verifies source and receipt of funds, prepares board and shareholder approvals, completes company filings, makes any RBI reporting and records conversion or repayment. Keep bank advice, executed instruments, valuation support, approvals and acknowledgements together in the data room. Filing dates and forms can change; verify them with current official guidance.
Convertible funding questions
Is a convertible note always better than setting a valuation?
No. It can defer one negotiation, but it adds conversion, maturity, repayment, interest, dilution and compliance questions. Compare the full outcomes with a priced equity round and a loan.
Can a foreign investor fund any Indian startup through a convertible note?
Do not assume so. Eligibility, permitted sectors, instrument conditions, payment and reporting rules depend on current FEMA and foreign-investment law. Get transaction-specific advice before signing or receiving money.
Does a convertible instrument avoid dilution?
No. It may delay the share issue, but conversion can issue shares later. Model the conversion formula and other rights on a fully diluted basis before accepting terms.
Can founders download a note template and use it unchanged?
That is risky. Instrument availability, company approvals, investor residency, tax, accounting and filings may differ. Ask an Indian startup lawyer and accountant to review the exact terms and a conversion model before the company accepts funds.
