Investor Due Diligence: How Singapore Startups Prepare (Checklist and Data Room)

By Lucas Seah, Founder of Excellence Singapore Group | Last Updated: July 2026

Investor due diligence is the verification stage of a fundraise. Once an investor decides to back you, they confirm that the company, the numbers and the paperwork match the pitch before money moves. For a Singapore startup, that means ACRA records and the constitution, management accounts and the cap table, IRAS filings, CPF and employment records, and IP and key contracts, assembled in an organised data room. The depth scales with the round: pre-seed is light, Series A can run for weeks. This guide covers the stages, the Singapore-localised checklist, the data room and the red flags that kill rounds.

Key Takeaways

• Depth scales with stage: pre-seed is light, seed adds financial and cap table checks, Series A is a full legal, financial and tax review (market practice).
• Most Singapore seed rounds run on management accounts and unaudited financial statements, not audited accounts.
• Build the data room before the term sheet arrives; a complete one can shorten the round by weeks.
• Classic round-killers: a cap table that does not reconcile, late ACRA or IRAS filings, CPF gaps, and IP never assigned to the company.
• A fractional CFO can make a startup investor-ready in weeks rather than months.

What is investor due diligence?

Investor due diligence is the review an investor runs before completing an investment. At pre-seed and seed, investors usually do it themselves; by Series A, external lawyers and accountants work through a formal request list. The process is largely confirmatory: the investor has decided to invest on agreed terms, and diligence tests whether anything contradicts that decision, with gaps surfacing as price adjustments, extra warranties or conditions to completion. For the wider raise, our guide to startup funding and grants in Singapore maps the stages end to end.

How deep does due diligence go at each stage?

At pre-seed, the company barely has a history, so the review is about the founders: track record, commitment, and how the equity is split. Expect to share your ACRA business profile, constitution and the terms of the instrument you are raising on. Many pre-seed rounds close on a SAFE or CARE precisely because the paperwork is light.

At seed, the numbers arrive. Investors ask for management accounts, bank statements, early customer contracts and a cap table covering the ESOP pool and any outstanding convertible instruments. A cap table that does not reconcile with ACRA records is the most common stumble here; our cap table and dilution guide explains why the two differ.

At Series A, diligence becomes a project. The lead investor’s lawyers issue a request list covering corporate, financial, tax, employment and IP matters, and the review commonly runs four to eight weeks (market practice).

The stage gap is what catches founders: records that passed a seed cheque are nowhere near Series A standard. A fractional CFO closes the gap early, keeping accounts, cap table and filings continuously investor-ready rather than scrambling after the term sheet lands.

What goes on a Singapore startup due diligence checklist?

Request lists are broadly standard worldwide; what changes in Singapore is which documents prove each point. This checklist maps the five categories to what a Singapore private limited company actually holds.

Category	What investors expect to see	Notes for Singapore founders
Corporate	ACRA business profile Constitution Registers of members, directors and controllers Board and shareholder resolutions	Your ACRA profile shows issued shares only; options and unconverted instruments live on the cap table
Financial	Management accounts (P&L, balance sheet, cash flow) Unaudited or audited financial statements Cap table with ESOP grants and SAFE or CARE instruments Bank statements	Management accounts plus unaudited statements are the seed-stage norm (see below)
Tax	ECI filings Form C-S or Form C returns Notices of assessment GST returns if registered	Unfiled returns are visible immediately; bring filings current before the room opens
People	Employment contracts with key employment terms Payslip records CPF submissions Work passes for foreign staff	KETs and itemised payslips are mandatory for most employees; every foreign hire needs a valid pass
IP and contracts	IP assignments from founders and contractors Trademark filings Key customer and supplier contracts Licences	IP never assigned to the company is the classic round-killer

Two rows deserve extra attention. On financials: most early-stage companies qualify for the small company audit exemption, so seed investors expect management accounts and unaudited financial statements rather than an audit. On people: key employment terms and itemised payslips are mandatory for most employees, and every foreign hire should map to a valid work pass; see our Employment Pass application guide.

What is a data room and how should you structure it?

A data room is a permission-controlled shared folder holding the documents investors will review: for most startups, a well-organised Google Drive, Dropbox or dedicated data room tool. Structure and completeness signal how the company is run, so mirror the checklist:

1. Corporate: ACRA business profile, constitution, registers, resolutions
2. Financial: management accounts, financial statements, bank statements, financial model
3. Equity: cap table, ESOP plan and grants, SAFE or CARE instruments, prior round documents
4. Tax: ECI, Form C-S or Form C, notices of assessment, GST returns if registered
5. People: employment contracts, CPF records, work passes, contractor agreements
6. IP and contracts: assignments, trademarks, key contracts, licences

Keep one index file, save PDFs with consistent names, and update the room as documents change.

What red flags stop investors?

These patterns recur in failed rounds. Disclosed early, most are survivable; discovered late, each reads as concealment, and the concealment kills the round.

• A cap table that does not reconcile: verbal equity promises, side letters, or option grants without board approval.
• IP outside the company: code written before incorporation, or founders and contractors who never signed assignments.
• Late or missing filings: overdue ACRA annual returns, unfiled ECI or corporate tax returns, CPF arrears.
• Numbers that move: deck revenue that does not match the management accounts, or accounts that change between meetings.
• Undisclosed related-party dealings: loans to directors, or sales routed through a founder’s other company.
• Founders without paperwork: no employment agreements for the founding team, or founder shares with no vesting.

How does a fractional CFO make you investor-ready in weeks?

Diligence readiness is a defined project with a finite document list, so it outsources well. A fractional CFO runs it as a short engagement: reconcile the cap table against ACRA records and board approvals, bring management accounts current and tie them to the deck, sweep the ACRA, IRAS and CPF filing history for gaps, chase unsigned assignments, then assemble the data room with an index. Once the round starts, the same person fields the investor’s finance questions so the founders can keep selling.

Frequently asked questions

What do investors look for in due diligence?

Investors verify that the company matches the pitch: clean ACRA records, a cap table that reconciles with board approvals and filings, credible management accounts, up-to-date tax and CPF filings, IP owned by the company, and signed key contracts. The later the round, the more of the list they test.

What is a data room for fundraising?

A data room is a permission-controlled shared folder containing the documents investors review during a raise: corporate records, financials, the cap table, tax filings, employment records, IP and key contracts, usually a Google Drive, Dropbox or dedicated tool with labelled folders and an index.

How long does startup due diligence take?

As market practice, a pre-seed review can finish in days, a seed round typically takes two to four weeks, and a Series A review commonly runs four to eight weeks. A complete data room is the biggest factor in landing at the short end of those ranges.

Do I need audited financials to raise a seed round in Singapore?

Usually not. Most seed investors accept management accounts and unaudited financial statements, because most early-stage companies qualify for the small company audit exemption. Audited accounts become relevant once you pass the exemption thresholds or at later rounds where investors ask for them.

What red flags stop investors in due diligence?

The recurring ones: a cap table that does not reconcile with ACRA records or board approvals, IP never assigned to the company, overdue ACRA, IRAS or CPF filings, deck numbers that do not match the accounts, and undisclosed related-party dealings. Disclosed early, most are fixable.

When should I start preparing for due diligence?

Before you start pitching, not after the term sheet. A data room takes weeks to assemble when records are in order, longer when they are not. Run the checklist the day you decide to raise, and fix gaps while conversations are still early.
