Sell It By Hand: How to Sell a Startup MVP Before You Code

One startup idea from Y Combinator, turned into a US$2,997 offer that takes real payments, without writing any code.

Part 1 is the research and the plan. Part 2 is the build: the page, the free funnel in front of it, the Stripe deposit, the intake form, the agreement and the work done by hand behind it. Every prompt and template is in the free worksheets below.

What is a manual MVP?

A manual MVP (also called a concierge MVP) is the smallest version of your product that one person can deliver for the first few paying customers. Viaweb built merchants’ online stores for them by hand. Stripe’s founders installed it on customers’ laptops themselves. Airbnb went door to door in New York signing up hosts. The manual work wasn’t a stopgap: it’s how they learned what to build.

In this workshop, instead of building software that turns customer feedback into a roadmap, I sell the job itself to product teams as a two-week Feedback to Roadmap Sprint, delivered by hand with Claude. Software comes later, and only for the steps that repeat.

Part 1: How do you research and plan a startup idea?

In Part 1 I find the idea, check it’s worth pursuing, and turn it into a plan:

• Find an idea. Y Combinator’s Requests for Startups is a good list, but your own industry experience is better. Ask of every idea: what could one person deliver by hand next week?
• Shortlist it with four filters. Does a business pay? Can you reach the buyer this month? Can one person deliver it? Do they already pay for something like it? I dropped two of my three ideas here.
• Research it with Claude. One deep research prompt answers five questions: is the problem real, who pays, what do they pay today, what should you charge, and where should you start. The prompt is in the worksheet.
• Price against people, not software. A fractional product leader in Australia costs A$9,000 to A$18,000 a month (Fractionus). The Sprint is US$2,997 for the first three clients, then US$4,997.
• Check you can sell it by hand. Five questions about money, advice, agents, children and customer data. This idea came out Amber because it handles customer data, so it needs a data agreement and redaction before any AI touches it.
• Turn it into a plan. Five answers into the free 5-Minute MVP, and the plan arrives as a PDF.

Homework before Part 2: talk to five buyers. Ask them, “When did you last deal with this, and what did it cost you?”

Part 2: How do you build a manual MVP that takes payments?

In Part 2 I build everything the plan lists, then a free funnel in front of it:

• The offer. A two-week Sprint: one quarter of feedback reviewed, every item checked against its source, tied to lost deals and at-risk renewals, with full specs for the top two features. The guarantee: if the top five don’t feel defensible in the planning meeting, I revise them free within a week.
• The page. One prompt into Claude Design. The first version asked strangers to book a call straight away, so one refinement prompt put a free scorecard first. Then Claude turned the export into a WordPress theme.
• Getting paid. A 20-minute intake call to check fit, then a 50% deposit through a Stripe payment link, and the balance on delivery.
• The intake form and agreement. Seven questions on the site, and a one-page agreement with the data clauses: names removed, no-training AI tools, data deleted within 30 days.
• The manual backend. Seven steps I do by hand for each client, about 20 to 30 hours over two weeks. The steps that repeat are what I automate first.
• The free funnel. A scorecard, a free kit, an email-gated setup video and a short VSL. Give away the what, sell the how.

What should you build first?

Six things, in this order: the offer, one page, a way to get paid, an intake form, a one-page agreement, and a list of what you’ll do by hand. You don’t need a website to start talking to buyers, and you don’t need software to deliver the first five clients. If a buyer won’t pay for the manual version, they won’t pay for the app.

Frequently asked questions

What is a manual MVP?

The smallest version of your product that one person can deliver by hand for the first few paying customers, with AI and simple tools doing the heavy lifting. It’s also called a concierge MVP. Software comes later, only for the steps that repeat.

Can you sell a startup idea before building it?

Yes. Sell the result as a service, deliver it by hand for the first few clients, and take a deposit up front. If a buyer won’t pay for the manual version, they won’t pay for the app.

What do you need to launch a manual MVP?

Six things: the offer, one page, a way to get paid (such as a Stripe payment link), an intake form, a one-page agreement, and a list of the steps you’ll do by hand for each client.

How do you price a service you deliver by hand?

Price against the people the buyer would otherwise hire, not against software. A fractional product leader in Australia costs A$9,000 to A$18,000 a month, so a two-week Sprint at US$2,997 to US$4,997 is an easy comparison.
