If you are a marketplace startup, Is there any barrier or loop hole in attracting the early members from the supply side through equity?

One word: Royalties This means you generate the idea and develop it enough to look interesting to a larger company who would be willing to pay you a royalty for your idea. This happens all the time. Rock stars, authors and scientists routinely license their creative ideas to other companies who pay them a royalty. Anyone can do it. Your business, therefore, would be a think tank. You (and your team, if you have one) would consider the world's problems, see what kinds of companies are trying to solve those problems, and then develop compelling solutions that they can license from you. You have to be able to sell your idea and develop a nice presentation, a little market research and an understanding of basic trademark and patent law. The nice thing about doing this is that if you develop enough cool ideas you will have royalties coming in from a lot of different sources, this creates a stable, passive revenue stream that requires little or no work to maintain. Start in your spare time and plan on the process taking 3-5 years. Set a goal to have a few products in the market that provide enough revenue (royalties) to cover your basic living expenses. Then you can quit your day job and dedicate more time and increase the momentum. A good idea business should have dozens, if not hundreds of license contracts generating royalties. It's possible to pull this off. And it is a fun job (I'm speaking from experience).

Probably not the answer you're looking for, but companies have so many unimplemented ideas that the likelihood of partnering to implement someone else's idea is really low. And besides which, the idea is not something that has much value in and of itself. If you're passionate in the idea, build it yourself. That's the only way you can have leverage.

I always suggest going "uncomfortably narrow" initially so that you can really dial in the user experience and build liquidity first. Going broad will be tougher as there's too much noise to signal. Also, it's best to fake the supply side initially of you can to improve the buyers side first, then figure out supply & quality afterwards if customers are buying and you've proven out a demand strategy that will work.

Dilip was very kind in his response. My answer might be a bit on the "tough love" side. But that's for you to decide. My intention, just for the record, is to help you (and those like you) on your path to success. And that starts with having a viable philosophy about entrepreneurial-ism and business. And I'm going to answer this because I get asked some form / version of this question very frequently from newcomers to entrepreneurial-ism. The scenario goes something like this: "I have a great idea. It's amazing, I love it, and I just KNOW it's gonna make me a ton of money. But I have no money right now so I can't afford to (fill in the blank with things like "to build it / create it / market it / etc" or "to hire the required staff needed to work in my business to sell it / develop it / etc"). And I don't want to tell anyone about my great idea because I'm worried someone will steal it and make MY million / billion dollars. But I can't afford to legally protect it either... So how do I launch without the skills to personally create the product AND no money to hire anyone else to do that either??" The answer is ... You don't. Look - let's be honest. All you have is an idea. Big deal. Really. I'm not saying it's not a good idea. I'm not saying that if properly executed it couldn't make you a million / billion dollars... But an idea is NOT a business. Nor is it an asset. Until you do some (very important) initial work - like creating a business model, doing customer development, creating a MVP, etc - all you really have is a dream. Right now your choices are: 1. Find someone with the skills or the money to develop your idea and sell them on WHY they should invest in you. And yes, this will mean giving up either a portion of the "ownership" or of future income or equity. And the more risk they have to take - the more equity they will want (and quite frankly be entitled to). 2. Learn how to code and build it yourself. MANY entrepreneurs without financial resources are still resourceful. They develop the skills needed to create what they don't have the money to pay someone else to do. 3. Get some cash so you can pay someone to do the coding. You'll probably have to have some knowledge of coding to direct the architecture of your idea. So you will likely still have to become knowledgeable even if its not you personally doing the coding. (This is not meant to be a comprehensive list of options... And I'm sure some of the other experts here on Clarity have others to add - and I hope they do) To wrap up - Here's my final tip to you that I hope you "get"... It's FAR more valuable to have an idea that a very specific hungry crowd is clamoring for right now - One that THEY would love and pay you for right now - Maybe even one they'd pre-order because they just have to have it - Versus YOU being in love with your own idea. [Notice I didn't say "an idea that some as-of-yet-undetermined market would probably love"] I wish you the best of luck moving forward.

I like to separate your question into 2 sub-questions: #1 How do we determine which side to charge? #2 How much is the right amount to charge? On #1, my answer is that you can charge the side(s) for whom you add the most value. In your examples, Uber really solves a big problem for drivers, it's that they sit idle for a good part of the day, so are willing to pay a lot for new leads. (their alternative is no work) Consumers are charged more for the convenience of a private car but they are probably not so much willing to pay more for a taxi, even if they can hail one from their phones. For AirBnB, it's a mix, it's a way for landlords to monetize idle capacity which they are willing to pay for, but it's also a way for a renter to pay less than they would normally pay for a hotel. On #2 (how much), I like to triangulate a number of factors: - What's the maximum amount I can charge one side, while still being a good deal for them. - How much do I need to charge so that I can become profitable? (the economics are quite different if you charge 3% vs. 12%) - What are comparable services charging for substitutes/competitive offerings? I will just add that there is no formulaic way to determine pricing strategies (curated vs. open), and it's a lot more about what's the comparable and what the value delivered is. That's how I approached the question while deciding the business model at ProBueno.com (my startup)
