What is Half Day Build?

Half Day Build is an event in which multiple people from around the world simultaneously attempt to convert their ideas into revenue in under 12 hours.Each person works independently on their own idea, from 12 noon to midnight, in their own time zone. Ideas can be as simple as selling a PDF for $1, or as complex as building a SaaS product, or anything in between or beyond. The only constraint is that you must begin executing on your idea at noon, and aim to generate revenue before midnight.

What should you build?

Build whatever you want.
The only condition is that you have to build it and try to generate revenue within 12 hours. It doesn't even have to be on the internet. Go build a lemonade stall if you feel like it!Ideally, try to build something that can continue to generate revenue after the Half Day Build is over.

Payment Gateways

To generate revenue, you need to allow people on the internet to pay you.While this sounds obvious, implementing a payment mechanism can be tricky. My advice would be to set up a payment gateway before your Half Day Build starts.Some gateways take time to approve your account, and depending on the country you live in, some might only let you use them if you have a corporate account.Here are a few options you can consider:- PayPal: For most countries, PayPal lets you receive payments directly to your account even as an individual and not a business. As an added benefit, PayPal is integrated into Gumroad which is the simplest way to sell digital products.- Stripe:A great payment processor to use if you are selling via a site like Shopify or selling a SaaS or subscription product. More complex to set up than PayPal, but is much more feature rich. Might be problematic for individuals (who aren't registered as businesses) to accept cross border payments from certain countries.- Razorpay (for India): Like Stripe, but for India. Loads of features if you have a business account in India and are looking to accept or automate payments online.- Instamojo (for India): Similar to Razorpay, but more freelancer friendly. Also lets you set up a shopfront pretty easily.- Other options: Based on your location, there will be tons of local options that comply with regulations in your country. If you know of an option I should add to the list, please get in touch with me on Twitter @louispereira and let me know.

Is this a course?

No. Half Day Build is not a course. It is just a group of people that build things simultaneously.I will provide material (tools, guidelines etc) that has helped me on my journey as a builder, and will continually add helpful content as other participants send them over. You can go through them at leisure, before, during, or even after your Half Day Build.There will also be a Discord server for you to meet other builders and ask them for help or support, but that will be deleted a few days after the event.

How much does it cost?

Half Day Build is free and always will be.What's more? If you are successful in generating revenue, you'll end up richer than you were when you started.

Do I need to be an experienced builder to participate?

Ideally, some experience in building digital products is useful.However, that is not a pre-requisite. Even if you're completely new to building things, you could start simple and just create an educational info product (PDF, Notion Doc, etc) based on your unique skillset.If you want to use this as an opportunity to learn to build things for the first time, you can refer to the resources section of this website and identify and play around with tools that will help you build things like websites, web apps, or mobile apps without code.

Why do I need to join you folks? Can't I do this by myself?

Of course you can!We're just doing it together because it might be fun to build things simultaneously (and take over Twitter with our posts). Man is a social (media) animal after all.Besides, I'll setup a temporary Discord server where you can chat with other builders, see what they're building, help them out if needed, and maybe make a few new internet friends.

What if I can't code?

No stress. Most of us can't.You can build a lot of stuff using NoCode tools that I've linked to in the resources section of this website. You don't even have to build something complex. You could just use Microsoft Word / Google Docs to create a PDF that you can sell.Obviously if you can code, and code fast enough to ship something and generate revenue in 12 hours, you're more than welcome to impress us with your skills!

What if I fail to reach revenue?

No problem. A lot of us will.Failing alone is scary.
Failing together is fun.Like most things in life, you'll enjoy this more if you treat it like an experiment, not an exam.
