Buyer Decision Checklist

Buying from an early-stage Singapore tech startup can get you newer technology and faster iteration, but the real questions are runway, who supports the product if the team pivots, and how your data is protected. Use this checklist before you shortlist.

How to evaluate a tech startup vendor in Singapore

  • Ask about funding stage, runway, and revenue traction so you can judge whether the company can support the product through your contract term — and confirm the ACRA-registered entity and UEN behind the brand.
  • Request two reference customers running the product in production in Singapore, ideally at a similar size, and confirm the deployments are still live rather than quietly discontinued.
  • Pin support and continuity in writing: response-time commitments, who maintains the product if the founding team changes focus, and a source-code escrow or data-export path so you are not stranded if the company winds down.
  • Confirm PDPA accountability — where data is hosted, how it is minimised and deleted on request, and what security controls (encryption, access control, breach process) exist even at small scale.
  • Check grant eligibility and pricing transparency: whether the solution is PSG pre-approved or supportable under EDG or Startup SG, and get unit pricing for onboarding, overages, and renewal alongside the headline subscription.
  • Plan an exit before you sign: agree data portability, contract length, and notice terms so a pilot can scale or be unwound without lock-in.

  • Ask for a written scope of services before comparing quotes.
  • Request evidence of relevant certifications and their current validity.

Questions to ask

  • What is your funding stage and runway, and can you support this product through our full contract term?
  • Can you share two Singapore production references at our size that I can speak to directly?
  • If the team pivots or the company winds down, how do we keep the system running and export our data?
  • Where is our data hosted, and how do you meet PDPA obligations on minimisation, deletion, and breach response?
