Can someone invest in a single product instead of an entire company?

Short answer: Of course! Many angel groups require you to submit through Gust because it offers a consistency and makes reviewing applications easier. But not all use Gust same as not all use AngelList... I haven't met an angel who frowns upon using multiple platforms. I would encourage you to leverage your twitter and Facebook or Instagram to meet angels and get in their radar (don't hassle or stalk) just try to get exposed a bit to them by being part of the same meetup group, follow the same blog, membership... Subscribe to their own blog.. And when you submit funding request considerations do please send a follow up email or a call or basket of fruits if you have contact them before.

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.

It varies and it's very very specific to what you want to develop. The concrete design of your circuit matters. Also prototype building costs are usually a factor 10-100 higher than series. If you already have your prototype then you can shop around various manufacturing companies. To do that, you need Gerber files (your PCB design) and a bill of materials. You also need to think about casing: designing it and creating the mold is expensive. If you don't have your prototype yet, I recommend having it engineered in eastern Europe. Custom engineering is cheap there and high quality. IP protection is a problem. One thing to do is to distribute the work to different manufacturers. For the design phase you are safer if you design your prototype in Europe or the US where international patent laws apply. I could give you more specific advise in a phone call, getting to know a bit better what you are trying to build.

What of the following things does your startup have? > Founders who have graduated from prestigious universities / previously exited companies to known acquirers / worked for a known companies (with known being a brand-name company such as Google, Amazon, Facebook etc) > Three or more months of statistically meaningful growth (e.g. for easy sake, double digit growth of a number in the thousands) > At least one investor who is active on AngelList (defined in the ideal state by at least one investment in a company who raised their round through AngelList and ideally whose social graph is connected to "high signal" members of the AngelList network) If you have none of these things, then at least, have advisors and referrers who have a strong AngelList profile. And another option is to seek out the AngelList scouts and pitch them directly. They are more open to this than anyone else and I've seen companies with very little traction and very little social proof get featured because a scout believes in the founder and/or the story. Without any or most of the above, it will be difficult to stand out or build relationships via AngelList, in my opinion. I assume now AngelList operates on a concept similar to the LinkedIn "degrees of connection" model, whereby an entrepreneur can now send unsolicited messages to investors so long as there is a degree of connection between the investor and the company. I get a few unsolicited emails a week from companies whose advisers or investors aren't people I follow but that because of the way they determine "connection strength", these unsolicited emails still gain my attention. I assume this is the case for all investors. So the more that you can build your list of advisers and referrers, the more connections you can solicit. That said, AngelList's inbound email system is almost entirely ineffective for "cold" emails to really high-profile investors. Happy to share with you what I think to be your best options for raising profile for your company.

Ask yourself: -Do you believe in their vision? -Would you leave everything you have to work with them to make their dream come true? -Do you have strong data that tell you that what they say will happen it's true? -Do you think the founders are the best to accomplish what they are going for? -Is it everyone in their team in love with what they are doing? It's important to take in consideration the legal/boring part of investing, but it's not the most important. As betting on horses, there will be only one that wil win (in their space). Are you beating for the right one? Ask yourself that. And stand along your decision
