Mexico - San Antonio


3 DAY STARTUP  San Antonio Texas

July 24 – 26, 2015 @ Geekdom
110 E Houston St


3 Day Startup is a 72-hour learning-by-doing workshop that help entrepreneurs launch companies. This program is designed for Latin American entrepreneurs ready for the US market.



Bootcamp (1-2 weeks before program date): Participants meet, get introduced to key entrepreneurship principles, and learn best practices for maximizing the 3 Day Startup program experience.

Day 1: Participants arrive – with or without startup ideas – and a facilitator leads the group through dedicated brainstorming, preliminary pitches/feedback, and team selection modules. Some teams work late into the night and others prefer to rest up in preparation for day 2.

Day 2: Customer discovery (teams exit the building or hit the phones and talk to potential customers), structured mentorship, intermediate pitches and feedback sessions. Day 2 places heavy emphasis on business model generation.

Day 3: Continued execution (including pitch workshops) leading into final pitches/demos to an esteemed panel of mentors and investors.

What does the weekend look like? You and the other selectees will start a technology company over the course of three days. We cater food, drinks, snacks, and coffee, pick the best ideas for a software startup during the Friday brainstorming session, and release a minimal prototype by the end of day 3. The goal is to build enough momentum among a network of motivated people to sustain the company beyond the weekend.

Why San Antonio?  San Antonio is one of the fastest rising startup scenes in the United States. A startup community needs three things to flourish: investors, successful startups and an inspired co-working space. San Antonio has them all. Furthermore, in contrast with other regions, such as San Francisco and New York, the cost of living in San Antonio is ridiculously affordable.

How do I get to San Antonio for 3 Day Startup? We will not be able to cover any travel or lodging costs, though we will point you in the right direction for places to stay.

If I participate, what do I get out of the weekend? The worst case scenario is that you will work with brilliant people from numerous disciplines toward the goal of launching real companies and products. Great connections happen at 3 Day Startup: cofounders meet, complementary skill sets collide, and friends are made. The best case scenario is that you will be a cofounder of a wildly successful new tech startup.

What kind of ideas are allowed? Ideas with scalable business models are strongly preferred.  We also optimize for ideas that will require a strong software base. Our selection criteria for ideas are (1) your amount of passion and (2) the amount of research on your own idea that you perform before your interview.

What about food? Sleep? 3DS caters all meals, drinks, and in-between snacks. Sleep is optional. Participants can bring a sleeping bag, or they can go home to rest.

What is your rate of success? First of all, check out some of the companies that have been started by graduates of 3 Day Startup here. Our main metric for success is how many of our alumni found companies that take investment, generate revenue or enter accelerators.  It is common to hear the word “startup” get thrown around.   When we say startup, we mean the real thing: companies that are making money or taking investment.

Per program, 3 Day Startup result in more successful startups than any other weekend entrepreneurship event. We have run 200+ programs in the US and internationally, and those have given rise to 79 companies that have cumulatively received over $79 million in funding. 29 companies from 3DS have been accepted to accelerators such as Y Combinator, Tech Stars, 500 Startups, Capital Factory, Austin Technology Incubator and Dreamit Ventures. On average, each 3 Day Startup program has generated more than one successful startup.  This includes programs in mature and nascent entrepreneurship ecosystems. More FAQs here.
