Aaron Marco Arias

Hi there! ✌ I’m Aaron, a content strategist with 7 years of international experience. In 2020, I co-founded Postdigitalist, a marketing consulting firm that helps tech brands across storytelling, content marketing, and SEO. I’m on GrowthMentor to help early-stage founders while diversifying my experience.

• 

  Branding

  I’ve worked with founders and teams to build brands that feel authentic and consistent, whether that’s through messaging, visual identity, or how a product shows up in culture. Especially in the age of AI-generated content, culturally-informed, differential branding is your best unfair advantage.

• 

  Content marketing

  I've been working in content marketing since 2017. Preferred platforms and SEO best practices may change, but the fundamentals of content marketing stay the same: Make something useful that people want to share with others. If you need help designing a product-led content strategy, I'm probably the guy.

• 

  Conversion rate optimisation

  Traffic is nice, but conversions pay the bills. I’ve run experiments, built funnels, and optimized customer journeys to turn curious visitors into paying users. CRO is about removing friction, testing hypotheses, and designing experiences that make saying “yes” feel natural. If you've been investing in marketing aggressively but the results fall short, this is where we start.

• 

  Copywriting

  I started my career as a junior copywriter. And throughout these years, some of my most successful partnerships have been centered around helping founders & teams find the right language to explain their vision + product to different audiences - from prospects to investors.

• 

  Email marketing

  Email marketing is a great channel. Its many pros make it absolutely essential for growing a brand. Email marketing is ubiquitous, it’s user-led, it's personal... plus, your email audience may be the only one you actually own. You could get each and every one of your social media profiles shut down, and your email audience would still be there. Time and time again, I've seen the impact of sending the right email at the right time.

• 

  Idea validation

  Before you scale, you need to know if anyone actually wants what you’re building. I’ve guided teams through demand validation processes that save time, money, and a lot of headaches. From simple smoke tests to structured customer interviews, I focus on finding real signals that tell you whether it’s worth doubling down or pivoting fast.

• 

  Personal branding

  People buy from people - especially from people they like. But personal branding playbooks that recommend calculating every move and treating every relationship as transactional don't work! I help you find your focus so you can reap the benefits of personal branding while staying true to yourself.

• 

  Product marketing

  I see product marketing as the bridge between what you’ve built and why people should care. It’s about context, storytelling, and making sure your product lands in the market with impact. Over the years I’ve helped startups sharpen their positioning, craft launches that resonate, and align product with go-to-market strategies that actually drive adoption.

  Figma

  7 years of experience

  Probably one of the best design tools out there. My favorite platform for collaborating with product & brand design teams. Also love using it for pitch decks and strategy presentations!

• 

  Webflow

  6 years of experience

  Perhaps the best no-code platform for building marketing websites. If you're in the process of deciding where to build your startup's site, Webflow is probably the way to go.

• 

  Google Analytics

  7 years of experience

  I've been working with Google Analaytics for years - just like everyone else who does SEO. However - on a regular basis, I pay more attention to PostHog.

• 

  Semrush

  7 years of experience

  Although the strategic value of keyword research is usually overestimated, it's good to have a go-to keyword research tool. Due to its international coverage (and dozens of other features), Semrush is that tool for me.

• 

  Wordpress

  13 years of experience

  I've been using Wordpress since high school. It's not the most modern or versatile CMS out there, but it does the job. Only big con: SEO is an uphill battle!

• 

  Cryptocurrency

  I've been working in the crypto industry since 2020. I've been lucky enough to work with some of the most celebrated startups in LATAM and beyond, covering everything from branding and storytelling to SEO strategy.

• 

  Digital Media

  I've collaborated with new media companies across branding and content operations optimization. Frankly, this sector is underrepresented in my experience. I'd love to work with more founders building media companies!

• 

  EdTech

  I've led SEO and email marketing efforts for a couple of educational platforms, with great success. It's another sector I haven't had a chance to work with enough!

• 

  FinTech

  I've led branding and content strategy efforts for several FinTech startups in LATAM and Europe. Transparency + accuracy + accessibility are the baseline. What's actually interesting is deciding what to build on top of that.

• 

  SaaS

  I've worked extensively with B2B SaaS startups - especially in product-led content marketing and SEO. Most startups over-engineer their content efforts, relying on hacks and best practices far too much. I flip the script towards radical simplicity with granular performance tracking. In short: Do less but measure it better, and discontinue anything that doesn't work.
