Intuitive app that helps you test new ideas at low cost.Cons:
None that I've experienced so far.
I enjoy using Javelin, it's a great tool for early stage, pre-product-market-fit startups. I also appreciate the wealth of knowledge about the Javelin method that is available on the site. Educational and functional, I can't wait to see where Trevor and Grace take this product.John Light has used this product for one year.
If you're looking for a low risk way to test new product innovations, Javelin gives you a framework designed by experts.Cons:

Looking forward to seeing the next generation of great ideas and business models that are developed now that Javelin has reached 1.0.Michael Gold has used this product for one year.
It's like having a guide to help you fill out the assumptions you want to testCons:
I have not gone through the entire interview cycle to have an informed opinion
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.Ray Wu has used this product for one day.
Good framework, well-structured. Run time-boxed experiments. Quickly iterate and identify the right problem, customer and solution.Cons:
Nothing that can't be done IRL without a digital equivalent.
We've used the JEB method on all ideas our startup has worked on so far, all with great success. But after you get familiar with the process and methodology, those with more tactile tendencies can rely on good old-fashioned sticky notes, whiteboards and pens.Faiz Fadzil has used this product for one month.
Easy to set up, quick to test hypothesis, Hypothesis testing is FREE.Cons:
Interview templates and AdWords Integration is PAID. Should have had a Freemium model.
Amazing and must use tool for anyone who is trying to validate their business idea.
The tools helps you identify the right customer segment and their top problem by means of customer interview and landing pages.
Will save months of time if used appropriately.Rohith Veerajappa has used this product for one week.
Holistic practical tool for every serious entrepreneur who want to know quickly how much His/Her idea suck :)Cons:
I’m not aware of any major cons. Maybe tune up the mobile version little bit?
I believe that most entrepreneurs can find this tool very useful anytime they want to test a new idea. If you’re willing to put in the work, Javelin will guide you through the lean process of validating your idea with the real costumers. In the world where everything is relative and most people are “thinking by feelings” it’s just so valuable to have a holistic and practical tool which guides your through the “reality check” quickly and efficiently. I’m using in for couple months and I love it! I definitely recommend you to sign up and test it ~ it’s for free.Marek Koyš has used this product for one month.
A must have tool for any up and coming startups!Cons:
Haven't found any cons so far.
Provides a repertoire of tools for startups to validate their ideas and understand customers needs to make better decisions in the direction of the startup. Especially love the feature of auto-transcribing interviews and to gauge the likeliness of conversion. Highly recommend to all new startups to check it out!

It's a full stack product innovation service. How do you not waste time and precious resources? It's simple. Use Javelin.Cons:
Interviews are big aspect of this platform, but many entrepreneurs may undervalue the importance of speaking directly to the customer.
Trevor, Grace, and Ryan are all veterans in the field. They've helped many startups navigate the perilous early stages of customer acquisition and product development. They've taken the lessons they've learned over the years and turned it into a platform that can help any entrepreneur avoid failing slow.Brooks Rao has used this product for one month.
Love the method and I've used with in my own accelerator called MOX. We use it to validate ideas and help our startups grow in new marketsCons:
Nothing right now, it's a solid product.
This method works, it help people understand what they don't know. What they don't know is the most dangerous and can kill them. The platform is free and lets anyone validate their ideas.... It's awesome!Ryan Shuken has used this product for one month.
Validating customers who love your product before you build or invest too much is invaluable. It's incredible that this is free to use nowCons:
Waited forever for something like this, so happy it's here.
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.Shuken has used this product for one month.
Great way to capture & track customer validationCons:
None so far
If more & more startups begin to use Javelin, this can become de facto standard for investors to do due dilligence on the startups they are investing in.Kapil Kane has used this product for one week.
Holds your hand through the process of coming up with customer hypothesis to finding product market fit.Cons:
There was an issue with the automated dialing feature a little while ago so I haven't tested it yet.
I'm working on my first startup as a solo-founder and using Javelin to help sketch out and conduct customer interviews has been awesome for me. I just finished my second interview today (in person). The UX is really clean and it's allowed me to stuff a lot of different thoughts and ideas into it. Since it forces me to be clear about what I'm doing I've been much more focused than I would have been if I solely relied on what I've picked up from books and videos. I'm also excited about seeing the digital and IRL communities grow with the tool!Casey Abbott Payne has used this product for one month.
All set up, just try it with a project, real or fake, even for testing or educational is a great toolCons:
