Convertible Note Singapore

A convertible note is a short-term debt instrument used in Singapore startup financing that converts into equity shares at a future funding round, typically at a discount to the next round price. It is commonly used by early-stage startups to raise seed capital before a formal valuation is established. This article is for informational purposes only and does not constitute financial or investment advice.

For Singapore investors and founders, understanding convertible notes is increasingly relevant as the local startup ecosystem grows. With over 4,000 active startups and a vibrant venture capital scene supported by Enterprise Singapore and the Monetary Authority of Singapore (MAS), convertible notes have become a standard seed-stage financing tool alongside SAFEs (Simple Agreements for Future Equity).

What Is a Convertible Note?

A convertible note is structured as a loan that automatically converts into equity when a qualifying financing event occurs — usually a Series A or seed round at a defined minimum raise threshold. Until conversion, the note accrues interest (typically 5–8% per annum in Singapore deals). If the company fails to raise a qualified round by a maturity date (usually 18–24 months), the noteholder can demand repayment or negotiate an extension.

Unlike equity, convertible notes do not require setting a company valuation at the time of issuance. This saves time and legal fees at the seed stage when it is genuinely difficult to determine what a young startup is worth. The valuation question is deferred to Series A, when a more informed lead investor sets the price.

Key Terms: Discount Rate, Valuation Cap, Interest Rate

Discount Rate: Noteholders receive shares at a discount to the Series A price — typically 10–20% in Singapore. If Series A shares are priced at SGD 1.00 each, a 20% discount means the noteholder converts at SGD 0.80 per share, rewarding early risk-taking.

Valuation Cap: A maximum valuation at which the note converts, regardless of the actual Series A valuation. If the cap is SGD 5 million but Series A values the company at SGD 20 million, the noteholder converts at the cap — protecting early investors from excessive dilution.

Interest Rate: Most Singapore convertible notes carry 5–8% per annum simple interest. This interest typically converts into equity alongside the principal, not paid in cash. At Q1 2026, deal terms vary but 20% discount and SGD 3–10 million caps are common in Singapore seed rounds.

How Conversion Works

On a qualifying financing event, the outstanding principal plus accrued interest converts into preference shares (usually the same class as the Series A investor receives, but sometimes a separate seed class). The number of shares issued depends on which gives the noteholder more shares: the discounted price or the valuation cap price. Founders must model both scenarios before signing.

Convertible Note vs SAFE in Singapore

SAFEs (popularised by Y Combinator) are increasingly used alongside convertible notes in Singapore. Key differences: SAFEs are not debt — they carry no interest and no maturity date, so there is no repayment obligation. Convertible notes are legally classified as loans, which means they sit above equity in a liquidation stack if the startup fails. For investors, the debt seniority of convertible notes is a marginal protection. For founders, SAFEs are simpler but may be less familiar to Singapore-based lawyers and investors who are more comfortable with note structures.

Risks for Investors

Investing in convertible notes carries significant risk. Most Singapore startups fail, and even if the note is technically senior debt, recovery in liquidation is typically zero. Convertible notes are illiquid — there is no secondary market for early-stage startup notes in Singapore. MAS regulations require that private equity and startup investments via convertible notes are typically restricted to accredited investors (individuals with net personal assets exceeding SGD 2 million, or annual income over SGD 300,000).

Regulatory Context in Singapore

Under the Securities and Futures Act (SFA), convertible notes may be classified as debentures. Offers of debentures to the public require a prospectus unless an exemption applies. Most Singapore startup convertible note raises rely on the small personal offer exemption (to no more than 50 investors per 12 months) or the accredited/institutional investor exemption. Founders should obtain legal advice before issuing convertible notes to ensure compliance with MAS requirements.

At Q1 2026, valuation caps for Singapore seed-stage convertible notes typically range from SGD 3 million to SGD 10 million, depending on traction, sector, and founding team. Caps for deep tech startups can be higher.

What happens if a startup does not raise a Series A before the note matures?
