This is similar to "Who is hiring" post. I'm personally actively looking for co-founders, so thought it will be useful to start this discussion, and see if we can meet our next co-founders via HN.
Please submit your details if you're looking for a co-founder.
I'm currently working on a social shopping startup - Shopialize. Shopialize is a Founder Institute (http://founderinstitute.com) incubated company. Currently I'm the only founder and developer at Shopialize. I'm actively developing the product and hoping to launch beta by October.
I'm seeking a bay-area based talented and passionate backend developer to join me as a Co-Founder to build this innovative and valuable product which will help consumers to discover great products and save money when they buy products.
Responsibilities: As a technical Co-Founder, you'll be primarily responsible for scalable software architecture and backend technology. You need to have experience in data-mining, information retrieval, and search engine technologies. It'll be great if you have experience in semantic web and machine learning as well.
I'm proficient in PHP and MySQL technologies, but if you convince me that we need to use other technologies, then I'm open to listen and change if it makes sense.
Compensation: It will be generous co-founder equity. If you want cash as well, then we can discuss cash+equity model as well. But Shopialize is currently in a pre-financing stage, so cash will be reasonable. To start with, you can start working with me in the part-time with minimum time commitment of 20 hours per week. When the company secures financing, you can expect a salary that will rise over time as revenue grows. It will then require a full-time commitment.
Contact: If you are interested, then please write to me aditya.kothadiya at gmail.com. You can send me your resume, or link of exciting projects you've done. We can meetup locally and then discuss the details in person.
