It was brilliant how we learnt how to validate startup ideas with creative, manual experiments. Would highly recommend speaking to Jonathan Sun if you want to validate your idea.

When I apply the principles of pretotyping before proceeding into those stages it really helps me to see whether the feasibility for a business, product or idea is really there.

Taking his advice, I built an onboarding guide using no-code - pretotyping has changed the way I go about design projects. It's a valuable addition to anybody's toolkit!

What is Pretotyping?

Most aspiring founders/rookie entrepreneurs commit to business ideas too early, rather than testing a bunch at one time. This limits the amount of shots they have at success. Subsequently, this leads to a “rushed pre-seed” where a founder tries to get to that stage as fast as possible without actually looking at the quality of idea/business (but creates short term progress satisfaction). In addition, many don’t know how to test their business ideas effectively. Surveys have their place for understanding your customers, however, they aren’t a substitute for validating whether you have a quality idea in demand. 

Pretotyping helps rookie founders build better foundations for their journey by learning one of the most important skills: quick validation.

What is the difference between Prototyping and Pretotyping?

Prototyping asks the question, "can we build it" while pretotyping asks the questions, "should we build it."

How is pretotyping related to the learn startup?

Pretotyping is even leaner than Lean Startup and even more minimal than MVP.

When should I first start utilising pretotyping?

Generally when you first come up with your idea!

Will I receive a certificate?

Yes, only if you complete all the assignments and attend the live workshops. The certificate will be signed by Let's Level Up and your lead facilitator.

When will the live sessions be held?

The live sessions will be held 7-8pm British Summer Time (BST) every Tuesday during the 4 weeks

Will the fellowship be recorded?

Yes! As part of our bonus rewards you will have access to the learning material 

Is this fellowship live or pre-recorded?

The fellowship will be a blend of live workshops which are recorded so you can rewatch at any time. There will be pre and post-workshop work to complete each week. 

I have not received a confirmation email

Is there a refund policy?

You can request a full refund within the first 14 days of purchase before the fellowship commences. Subsequently, if you cannot attend the fellowship dates, you can opt to join another fellowship in this skill only once. Please see our terms and conditions for more.
