You’ve just landed in your startup’s marketing role. Maybe you’re a founder wearing multiple hats, or perhaps you’re the first marketing hire. Either way, the task ahead seems daunting: build a marketing function from scratch with limited resources and sky-high expectations.

I’ve been there. After working with dozens of early-stage startups, I’ve seen firsthand how the first 90 days can make or break a company’s marketing foundation. This isn’t just another checklist – it’s a battle-tested roadmap that has helped startups go from zero to consistent growth, even without a dedicated marketing team.

The Foundation Month: Building in the Dark

Most founders rush to create content or run ads, but that’s like building a house without a blueprint. Your first month needs to focus on something less exciting but infinitely more important: understanding.

Last year, I worked with a B2B SaaS startup that was burning through their budget on LinkedIn ads with minimal results. When we dug deeper, we discovered they were targeting the wrong decision-makers entirely. A few customer interviews revealed that while they were marketing to CTOs, the actual buying decisions were being made by DevOps leads.

This is why your foundation month is critical. Start by talking to your customers – aim for at least 15-20 conversations. Don’t just ask what they like about your product. Dig into their daily challenges, their decision-making process, and most importantly, the language they use to describe their problems. This goldmine of insights will fuel everything from your website copy to your ad targeting.

During this month, you’ll also need to set up your basic marketing infrastructure. Think of it as building your marketing command center. One of the most effective approaches I’ve seen is creating a simple but solid “marketing stack” that includes:

  • A reliable analytics setup (Google Analytics 4 is fine to start)
  • A basic CRM system (even a well-organized spreadsheet can work initially)
  • A content management system
  • A social media management tool

The Growth Engine Month: From Insights to Action

With your foundation in place, your second month is about building systems that generate predictable results. This is where many startups falter – they jump from tactic to tactic without creating repeatable processes.

I recently guided a startup that was struggling with inconsistent content production. Their founder would write blog posts whenever inspired, resulting in sporadic publishing and inconsistent messaging. We implemented a simple content system: every customer call would generate three content ideas, and every team meeting would end with five minutes of knowledge sharing that could be turned into content. Within weeks, they had a steady stream of authentic, valuable content that actually resonated with their audience.

The key to building your growth engine is starting small but being consistent. Choose one primary channel based on your customer research from month one. If your customers live on LinkedIn, focus there. If they’re searching for solutions on Google, prioritize SEO and content. The channel matters less than your commitment to it.

A practical approach that worked well for several startups I’ve advised is the “1-3-5 content framework”: 1 pillar piece of content each week (like a detailed blog post) 3 supporting social media posts 5 engagement activities (comments, shares, or personalized outreach)

This framework ensures consistent output without overwhelming your limited resources.

The Scale Month: Optimize and Expand

By your third month, you should have data starting to flow in. This is where marketing transforms from an art into a science. But scaling doesn’t mean doing more – it means doing more of what works.

One startup I worked with discovered that their technical blog posts were getting minimal traction, but their “behind-the-scenes” content showing how customers used their product was generating significant interest. Rather than stubbornly sticking to their original content plan, they pivoted to create more case studies and user stories, ultimately tripling their conversion rate.

During this month, focus on:

  • Analyzing your channel performance data
  • Doubling down on what’s working
  • Automating repetitive tasks
  • Creating systems for sustainable growth

The goal isn’t to expand to new channels yet – it’s to optimize your existing efforts and make them more efficient.

Looking Ahead: Beyond the First 90 Days

Remember, this roadmap isn’t about achieving overnight success. It’s about building a sustainable marketing foundation that can support your startup’s growth for years to come. The most successful startups I’ve worked with didn’t try to do everything at once. They focused on doing a few things well and built from there.

Your first 90 days won’t be perfect, and that’s okay. The key is to maintain a balance between strategic thinking and practical execution. Document your learnings, celebrate small wins, and keep iterating based on real data and customer feedback.

Marketing an early-stage startup isn’t about big budgets or complex strategies. It’s about understanding your customers deeply, creating systems that work with your limited resources, and consistently delivering value to your audience.
