Why an async‑first Singapore product studio can ship a prototype in 21 days

This week founders are talking about OpenAI opening Singapore Founder Day applications to Southeast Asia startups – a sign that the region is hungry for rapid, AI‑enabled product building. Read the announcement here. The buzz is about speed, access to agentic AI, and the need to iterate before the market decides. That’s exactly the problem I set out to solve with Product Pass, my fixed‑price, 21‑day sprint that runs entirely async.

Why async matters for a Singapore product studio

Singapore’s startup ecosystem is dense, multilingual, and increasingly remote. Teams are spread across coworking spaces, home offices, and sometimes even across borders. Traditional, meeting‑centric product discovery eats up calendar slots that could be spent building. An async‑first approach flips that script:

• Time zones become an advantage – I can hand off a design doc at 9 am, get feedback by noon, and ship code by the end of the day without a single Zoom call.
• Documentation is king – Every decision lives in a shared Notion or Google Doc, making hand‑offs painless and future‑proof.
• Focus over fatigue – Engineers and designers work in their peak hours, reducing context‑switching and burnout.

In practice, this means I can promise a complete product discovery package – vision doc, full PRD, database & network architecture, sprint timeline, a Next.js prototype, a private client portal, and Slack integration – all within three weeks.

The 21‑day sprint broken down

Each phase ends with a short async review: a comment thread, a recorded walkthrough, or a quick Slack poll. No synchronous stand‑ups needed.

What you actually get with Product Pass

1. Vision document – A two‑page narrative that captures the problem, target user, and success metrics.
2. Build‑ready PRD – Detailed user stories, acceptance criteria, and UI wireframes.
3. Database & network architecture – ER diagrams, API spec, and cloud infra recommendations.
4. Sprint timeline – A Kanban board that maps every story to a day.
5. Working Next.js prototype – Deployable on Vercel, with authentication, a basic data layer, and responsive UI.
6. Private client portal – All artefacts stored in a secure space you can access anytime.
7. Slack integration – Automated notifications for task updates and demo links.
8. Live hand‑off – A 30‑minute walkthrough, code repo access, and next‑step recommendations.

All of this is delivered for a flat $3,500 fee. The price includes the optional 15‑minute intro call, but the rest of the process is fully async, so you keep control of your schedule.

How we stay aligned without meetings

1. Kick‑off questionnaire – You fill out a form that captures goals, constraints, and preferred tech stack.
2. Shared Notion workspace – Every document lives in one place. I tag you on updates, you comment when ready.
3. Weekly async video recap – A 3‑minute recording summarises progress and flags blockers.
4. Slack channel – Real‑time questions get answered, but only when you ping me.
5. Milestone checkpoints – Day 7 and Day 14 each have a deliverable review; you approve or request changes in the comment thread.

Because there’s no calendar‑locking, you can keep your existing commitments while the product discovery runs in the background.

Pricing, deposit, and timeline

• Flat fee: $3,500 (no hidden hourly rates).
• Deposit: 50% due upfront to lock the sprint.
• Mid‑sprint payment: Remaining 50% on Day 15, after the architecture and sprint plan are approved.
• No‑surprise overtime: If the scope expands beyond the agreed PRD, we treat it as a new sprint.

The whole package is designed to be a low‑risk experiment for founders who need validation fast. If the prototype resonates, you can hand it to an in‑house team or a development partner with minimal friction.

FAQ

How async works if I’m not comfortable with written communication?

I provide a short 15‑minute intro call (optional) to walk you through the process. After that, all feedback can be given via recorded video or voice notes, which I transcribe into the docs.

What if I need changes after Day 21?

Product Pass ends with a clean hand‑off, but I offer a discounted “extension sprint” to iterate on the prototype for an additional $1,200 per week.

Do you build the full backend?

The prototype includes a minimal backend (Next.js API routes, SQLite or a managed Postgres instance). For production‑grade scaling, I hand over architecture diagrams and cloud‑provider recommendations.

Is the private portal secure?

Yes. The portal is hosted on a password‑protected subdomain of evenground.io, with HTTPS and two‑factor authentication optional for you.

Can I use my own design system?

Absolutely. Upload your component library during the PRD phase and I’ll reference it in the UI mockups.
