Thanks everyone for checking out Javelin! Would love to answer any questions you have. Making innovative products is difficult. You have to find the right early adopters and solve the right problems in the correct way. Having a business plan is not enough. You need to go out into the real world and talk with your customers to understand who they are and what is causing their current problems. Javelin connects you with customers to interview, while also providing you with tools that make recording, organizing, and analyzing their feedback simple and easy. Setting up a landing page to test your idea isn’t very difficult, but with Javelin, we take this concept a step further. Javelin gives you the ability to test multiple landing pages, track multiple customer acquisition channels, and compare your website copy and conversion rates, in order to provide you with a clear vision to which path will make you and your idea the most successful. On top of all of these features, once you begin your beta testing, Javelin can measure if your product is a MUST HAVE, (hand gesture or tone change) something that people can’t live without, or a NICE TO HAVE, meaning it will be difficult to scale.

@to Do the testing strategies work for every type of startup? e.g. tech for good?
@to @abadesi Yes, this is a methodology and process that works for any idea. We help connect you to potential customers to interview, help you analyze the interview data and calculate the business metrics for different ideas so you can easily decide which customer to focus on, which is the biggest problem to address, and which is the best solution to solve it.
@to Does your testing work in any other country outside of the US? We're in New Zealand and it's a different market.
@tricia_fitzgerald Hi Tricia, you can use Javelin anywhere in the world. For the On-Demand Interviews, there are many customers in the database in the Australia/New Zealand area. I'm not sure the exact number offhand but I will look into it for you! Also--we don't have the ability to target by location yet, but that will be coming very soon.
@tricia_fitzgerald @to I am from NZ and using it just fine.

Trevor and Grace are well known experts in bringing products from idea to market. This software allows companies to leverage their knowledge and insights at scale.

I was an early beta user of this product and have worked with Trevor and Grace since 2012.

Looking forward to seeing the next generation of great ideas and business models that are developed now that Javelin has reached 1.0.


If you're looking for a low risk way to test new product innovations, Javelin gives you a framework designed by experts.


It will be even more powerful with lots of users. So sign up :)

The hardest part for any startup I've built or worked with is finding paying users and fully validating your idea. It's not enough to have some paying users if you have never explored other customer segments and their pain points. You may not be servicing the largest pain point and the largest potential customer segment. I can not stress how this issue of building product in the wrong direction is, it can turn a great team, and a decent product into a failure.

For me it took years until I went through the lean startup machine to see how focused product validation helps. It's the opportunity cost of building product and spending time on something people don't want that scares me the most.

Javelin is the combination startup lessons and failures into a working model for startups. The teachings are in almost every accelerator in the world and javelin is here to bring this to everyone for free.

It's not enough to know what you want to build. Your customers need to want your idea, and want to pay for it. I've see this problem over and over again. Pushing though our own ego lets you build the best version of the product. This process of pushing beyond what you think, in to what you know is what the Javelin process does. This is what lean means for a startup. Our best intentions can divert our focus away from the prize, away from cash flow. This is why I love this process and I know it will help many people all over the world.


Validating customers who love your product before you build or invest too much is invaluable. It's incredible that this is free to use now


Waited forever for something like this, so happy it's here.

I've tried the previous iteration of Javelin and I didn't stick. I'm constantly doing interviews, and I really dig the new structured approach to formulate assumptions and interview directions.


It's like having a guide to help you fill out the assumptions you want to test


I have not gone through the entire interview cycle to have an informed opinion
