About Investor Due Diligence Support

A clear overview, in simple terms — what it is, why it matters, and how we handle it.

Quick answer

Once a term sheet is signed, the investor's lawyers and accountants review the startup's finances, tax position, company-law filings, FEMA compliance, contracts, IP and employment records. Issues they find become conditions, indemnities or a lower valuation. We manage the process for the founders: answering queries, fixing red flags fast and documenting exceptions in the disclosure letter.

Common findings are predictable — allotments without PAS-3, private placements without proper offer letters, TDS defaults, GST mismatches, missing FC-GPRs, founders' or freelancers' IP never assigned, and legacy angel-tax exposure for older rounds. Most can be regularised before closing if found early.

We act as the single point of contact for diligence queries, so the founders can keep running the business while the data room questions are answered accurately and consistently.
