3DS CleanTech San Antonio




October 19-20, 2019

Geekdom Event Center


3DS is a 2 day learning-by-doing workshop that teaches entrepreneurial skills in an extreme hands-on environment. Aspiring entrepreneurs from across San Antonio and Bexar County are invited to help solve the world’s biggest, messiest problems in clean energy, water, transportation/mobility, food, and waste/re-use.


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. 

Day 2: Customer discovery (teams exit the building or hit the phones and talk to potential customers), and structured mentorship, followed by final pitches in front of a panel of distinguished entrepreneurs, experts, and investors.


The program is free but you must apply to get in.

What does the program look like? You and 39 other individuals will start a cleantech company over the course of two days. We provide work space, invite participants with a wide range of backgrounds, cater food, drinks, snacks, and coffee, pick the best idea for a startup during the Friday brainstorming session, and release a minimal prototype by the end of day 2. The goal is to build enough momentum among a network of motivated people to sustain the company beyond the weekend.

If I participate, what do I get out of it? The worst case scenario is that you will work with brilliant people from numerous disciplines toward the common goal of building real companies and products. Great connections happen at 3 Day Startup: cofounders meet, complimentary 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.

I’m a student majoring in X. Should I even consider applying? The short answer is: yes. Our past participants have spanned everything from a freshman in psychology to a freshly minted PhD in Neuroscience. If you’re at all passionate about startups and technology, it is likely that you will be a valuable participant.

Can I apply even though I am not a student? Absolutely. Our goal is to recruit a diverse group of (very strong) student and non-student participants.

What kind of ideas are allowed? Ideas that pertain to cleantech and sustainability are strongly preferred.  

What about food? 3DS caters all meals, drinks, and in-between snacks. 

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 incubators.  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 400+ programs in the US and internationally, and those have given rise to 150+ companies that have cumulatively received over $157 million in funding. 34 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 university entrepreneurship ecosystems. More FAQs here.
