How can I negotiate participation in a new startup?

Just because two people are connected to each other on LinkedIn, doesn't mean that these two people have a strong connection to one another. So first, ask your Mentor directly whether (s)he knows this person well enough to make an introduction. Also, I'd suggest that instead of asking that the introduction be made via LinkedIn, that the introduction be made directly via email. The way this best happens is to email your mentor with a two paragraph email explaining why it is that you want an introduction to this person and explaining why you think this person would want to meet with you. Then your mentor can forward this email directly to this person with a request for an introduction. If the person replies to your mentor, your mentor will then connect you two directly. If the investor is interested enough to accept an intro, then you'll likely get a 30 minute to 1 hour in-person meeting or call scheduled. In terms of what that investor will be looking for, I've written a lot of answers to questions around seed-stage financing that I encourage you to review. I'm happy to schedule a quick call to give you some specific feedback on where you're at and how investors might perceive your progress to date. Best of luck with this connection!

As Ken suggested, there is a wide breadth of mobile offerings and although there are some great "mobile only" funds, each investor / fund has their own thesis that makes them interested in some but disinterested in others. Also, if your revenue generating, you should seriously consider bootstrapping further. Revenue is treated very strangely in early-stage investing and *might* work against you. AngelList is a great way to research investors but not effective in actually connecting with them. Find investors who you are confident will be passionate about what you're doing based on prior job experience or what you know they are investing in. Happy to talk in a call to help explain this further if you need more clarity.

Instead of calling it "comedy", aim for humor. Humor that supports a key discovery helps to anchor that insight in the investor's mind. I've coached many pitches, and find that when presenters are nervous they try to go for an improvised laugh, thinking it will cut the tension. However, in most situations, it comes off as just that: improvised and cheesy. Which confims to the audience that the presenter is nervous and unsure. Humor an advanced communication skill which requires strategy, planning and practice. The best humor is subtle and smart. The goal is not to get a laugh, but to get a knowing smile.

Have you considered crowdfunding? Investment grants will be able to take care of funding but crowdfunding has the benefit of taking care of funding and providing a customer base.There are many examples of teams without a fully working prototype being successful on these platforms. Kickstarter will be off the table but you have some great options with Indiegogo (https://www.indiegogo.com/) and the Brazil specific network Catarse (http://catarse.me/en) Of course, you will have to focus on things like presenting your story and getting attention for a bit but if you are successful you will have money for a prototype, access to a customer base and exposure that could bring some helpful people onto your team - even the angels and VCs you'll need to get to the next level. Message me if you need some help - I'm not personally an expert in crowdfunding but I can connect you with some of the best in the business.

Team is more important than the startup itself. Investors prefer invest in the Jockey over the Horse. There may be n number of reasons for not getting through the funding rounds. If your startup is able to provide 10x return I can invest straight away. However, I will look at the team first and foremost and then I will look at the management skills and then I will come to other metrics like traction and scalability.
