How we work
From strategy to output

01

Content strategy & research

We begin by immersing ourselves in your company, industry, business objectives, and audience. This deep research lays the foundation for everything we do, ensuring every decision and strategy is data-driven and with the right context. The right foundation sets the stage for the right content strategy, distribution, and conversion down the line.

02

AI workflow adaptation & Content OS setup

Next, we deploy AI-powered workflows tailored to your needs. We establish a content engine designed to produce high-quality, resonant content at scale. Our experts guide the adaptation of workflows to your brand’s voice and objectives, making sure we balance speed with precision and leverage automation to drive efficiency.

03

Content calibration

Once the engine is running, we calibrate every piece of content, ensuring it aligns with your strategy. Then, we publish and optimize it for maximum reach. We focus on rapid iteration—analyzing results in real-time and making quick adjustments to capture opportunities and build early wins.

04

Publish

With content in place, we expand our efforts to include developing lead magnets, building social distribution channels, and growing newsletters to amplify reach and engagement. We convert audience attention into leads and opportunities by crafting targeted calls to action and optimizing content for conversion. Our approach ensures that we’re not just creating content, but also turning it into tangible growth by systematically capturing and nurturing audience interest.

05

Scale, Refine, Test, Iterate, Optimize

Growth is a continuous process. We constantly adapt by doubling down on what’s working, refreshing content non-stop, and deploying new tactics quickly. By using data-driven insights, we ensure that every cycle of content creation and distribution builds on the last, driving sustained growth at scale.

All workstreams are powered by our unique combination of AI workflows with guidance from domain experts formerly at companies like Deepgram, Scale AI, TripAdvisor, and TechCrunch—giving you access to top-tier talent that would otherwise be unavailable to most organizations.

Our onboarding process is designed to quickly transform your growth initiatives without burdening your team:

Week 1: Discovery & Strategy

We begin with thorough research of your business, competitors, and audience before our kickoff meeting. We immerse ourselves in your brand positioning, messaging, and existing growth channels to develop a solid foundation of understanding. This preparation allows us to arrive at our first meeting with meaningful insights rather than basic questions.

Weeks 2-3: Foundation & Calibration

After aligning on objectives, we build your custom Content OS, setting up AI workflows tailored to your specific needs. We create initial content drafts for calibration, develop a comprehensive style guide, and establish production frameworks. During this phase, we'll collaborate closely to refine our approach, ensuring our outputs perfectly match your brand voice and strategic goals.

Weeks 3-4: Content Production & Quality Assurance

We begin producing content across your selected workstreams, implementing our rigorous quality assurance process that combines AI-enhanced checks with expert human oversight from our managing editors and growth strategists. This phase focuses on establishing consistent output while maintaining the highest standards of quality and brand alignment.

Weeks 4-5: Distribution & Amplification

With content flowing, we activate our distribution channels including social media, link building campaigns, and SEO optimization. We set up tracking systems and begin measuring early performance indicators to identify what resonates most with your audience and drives the best results.

Weeks 5-6: Conversion Optimization & Lead Generation

We implement conversion-focused elements including gated content, lead magnets, and optimized calls-to-action. This phase focuses on turning the traffic and engagement we've built into qualified leads and measurable business outcomes.

Weeks 6-7: Scale & Optimization

We analyze performance data from the first five weeks to identify winning strategies and double down on what's working. We refine our approach, scale successful tactics, and establish the foundation for ongoing growth. This final phase ensures you have a fully operational growth engine ready for long-term success.

Throughout the entire process, we work as an extension of your team in Slack, providing daily updates and transparent communication. This approach ensures you maintain visibility without the burden of extensive meetings or management overhead.

The onboarding phase sets the foundation for our ongoing partnership, where we continuously optimize and scale your growth engine based on performance data and evolving business priorities.

Your day-to-day contact will be a dedicated Growth Strategist, someone with a proven track record in driving growth and managing content programs. They'll be your point of contact, deeply involved in everything from strategy to execution, ensuring that your growth initiatives are on track. They're supported by a managing editor and a team of experts working in sync to deliver results.

Our ultimate goal is to drive real revenue for your business, but we recognize that it starts by building effective content, gaining distribution, and then converting that distribution into paying customers. We focus on optimizing controllable inputs because doing so consistently leads to the right outcomes over time. Here's how we approach each stage:

Phase 1 - Content Production

The first priority is getting a content strategy in place that scales. We focus on KPIs that ensure we're generating enough valuable content to get noticed:

  • Articles Published
  • Total Words Published
  • Pages Indexed by Search Engines
  • Keywords Ranked (early signals we're on the right track)

Phase 2 - Distribution & Reach

Once content is flowing, it's about ensuring people find and engage with it. This means nurturing and amplifying existing content to grow your audience and expand reach:

  • Organic Search Impressions
  • Organic Search Traffic (clicks, visits)
  • Average CTR (Click-Through Rate)
  • Number of Keywords Rising in Rank (top 3, 4-10, etc.)
  • Domain Authority and Referring Domains

Phase 3 - Conversion to Leads

Here, we leverage the reach we've established to create meaningful conversions. Our goal is to convert interest into real leads:

  • Visit → Subscriber / Lead Conversion
  • Conversion Rates by Offer, Page, or Topic
  • Lead Volume and Quality
  • Lead Engagement (e.g., Open Rates, Interaction Levels)

Phase 4 - Conversion to Revenue

The final step is about converting engaged leads into paying customers, making sure our content has ultimately driven business growth:

  • Lead → Meeting (or Product Signup) Conversion
  • Meeting → Sales Opportunity (or Product Activation)
  • Sales Opportunity → Closed Deal (Monetization)
  • Average Deal Size or Order Value
  • Customer Lifetime Value (LTV)

Success for us means creating a growth engine—starting with content that earns trust, building a distribution network that scales that trust, and then strategically converting that reach into tangible business outcomes. Every KPI ties back to this journey from content to conversion.
