Competitive advantage for startups

We've worked with dozens of clients over the years, form one person startups to large brands and we know secret sauce to success. A small organized team, perfect for nurturing your business needs.

Here are is the proof:

  • Series A round of funding.
  • Series B round of funding.
  • Investments of $800,000.00+ several times
  • Featured on Techcrunch several times
  • https://techcrunch.com/2017/10/24/startup-o-school-raises-800000-to-improve-sex-education/

We value transparency, good communication, and quality. We use technology that would serve the goal, but in general, it's Ruby on Rails, NodeJS and front-end (React.JS, React Native, Vue.js ...)

We are partners, not just a vendor. Contact us and see the difference.
