Hi, I'm German Calas.

A Growth Hacker, Entrepreneur, CEO, CMO & Advisor

I am a digital problem solver turned serial entrepreneur with over 15 years of experience starting, managing and growing online businesses including eCommerce, Marketing Agencies, Affiliate Marketing and Software-as-a-Service (SaaS). I’ve started over dozen online businesses as a bootstrap sole founder, forcing me to not only wear nearly every hat you can image a startup would need, but also strive to achieve profitability fast. Among all of the hats I’ve worn, I’m most passionate and experienced with Product Strategy, SEO, Growth Hacking, Revenue Strategy and Conversion Rate Optimization. These are the jobs and roles I’ve found lead companies to the fastest long-term success. I am currently working with several businesses as a Growth Hacking consultant, and co-founder/partner in a handful of other startups.

My Core Values

  1. Agility:  I value adapting quickly and pivoting strategies as needed in the constantly evolving digital landscape. The mindset and ability to move swiftly and make rapid changes in response to feedback, data, and new information are essential. Failing fast and iterating quickly is crucial for achieving the best possible results as quickly as possible.
  2. Creativity: I love to develop innovative solutions to help my, and my client’s businesses thrive. Thinking outside of the box is one of my specialties.
  3. Results-oriented: I value achieving tangible outcomes for myself and my clients, whether that’s increasing the profit margins or conversion rates, to lowering bounce & churn-rate.

What people who know me say about me

Roberto D. Marketing & Sales Guru

German and I have known each other for over 7 years, and he’s probably one of the smartest guys I’ve ever met. He’s passionate, dedicated, loyal and candid. When it comes to work, German’s the type of person who becomes obsessed with “solving the problems” and really diving into the customer’s shoes. The guy lives to work.? Honestly, I don’t think I’ve ever seen him work less than 100 hours a week. When he’s not working though, you’ll find him reading, spending him with his family or cruising around Denver in his One Wheel.

German’s is the most hard working, dedicated person I’ve ever met.

Jahdy L. CTO, Software Architect, Product Manager

Having worked along side German over the past several years, and having had the opportunity to witness success and failure in both professional and personal contexts, I am consistently surprised at how fiercely he resolves to persevere and beat the odds while energizing and inspiring those around him to follow suite.? He is an accessible administrator with proven executive acumen?able to navigate and overcome complex corporate obstacles with poise and resoluteness.

German?s ?out of the box? approach to problem solving, has pulled the company from the brink of certain catastrophe, having the tendency to turn the most improbable loses into sweeping wins.? Situations matching the aforementioned have taken place a few too many times to discount them as mere luck. Indeed, his consistently sharp performance and marketing prowess are unrivaled, and I?m fortunate to be able to consider myself as one to profit from his example.

A highly approachable leader to junior staff, and an inspiration to his senior level peers, I highly recommend German Calas as a highly capable visionary and executive and see unbridled success in his future, should he persist his current trajectory.
