Four metrics that actually shift when inbound kicks in.

  • −50%CAC, after inbound

    From $80-$200 per meeting on cold email and LinkedIn ads, down to $30-$90 once the inbound engine is running. Marginal cost of one extra lead trends to zero.

  • +2xLTV, after inbound

    Automated post-sale nurturing keeps your brand top-of-mind. Renewals smoother, upsell mechanical, churn cut in half on the cohorts we've tracked.

  • ×10Scale, after inbound

    The inbound system runs 24/7. Doubling traffic doesn't double your costs. Content published 18 months ago still pulls leads today. An asset that compounds.

Method · 4 steps

The classic inbound playbook, with AI in every step.

The four verbs still hold: Attract · Convert · Close · Delight. What changed is what sits inside each one in 2026. We keep the structure, we inject AI and automation everywhere it makes the work faster, more personalized, and cheaper.

  • Attract — classic SEO + AI SEO + targeted paid, three parallel tracks
  • Convert — funnel-staged lead magnets, A/B-tested landing pages, AI chatbots
  • Close — conditional nurturing sequences, AI lead scoring, sales handoff at threshold
  • Delight — automated onboarding, post-sale nurturing, referral loops, NPS-driven actions

Differentiator · AI nurturing

Lead nurturing personalized at industrial scale.

Capturing a lead via lead magnet is 20% of the job. Turning that lead into a signed customer is the other 80%. And 80% of 2026 nurturing is automatable. Every email is generated dynamically by an LLM with the contact's real-time context. No agency billing $80/hour for personalized copy can keep up.

  • Every email generated dynamically by an LLM with the contact's real-time context
  • 5 to 10 enrichment variables from Apollo, Clearbit, Phantombuster pulled at send time
  • Marginal cost: less than $0.02 per personalized email, regardless of volume
  • Replaces $80/hour copywriters with a workflow that ships 500 unique emails per week

We look at your inbound, you walk away with a plan.

Before we quote anything, we spend 60 minutes understanding your existing setup and what's blocking you. You walk away with a clear action plan you can execute without us, or a quote if you'd rather we handle it. Zero pitch, just an outside look.

  • Classic + AI SEO audit (Google rankings and citations in ChatGPT, Perplexity, Gemini, Claude)
  • Content audit (depth, freshness, search intent coverage)
  • Automation audit (nurturing gaps, lead scoring, CRM hygiene)
  • Top 3 quick wins actionable within 30 days

Our approach

How we run an inbound engagement.

Five steps, in order, with no sleight of hand. We don't skip the audit to ship faster, we don't spin up content before the intent map, and we don't hand you a dashboard without something to read on it. Each step has its own DOD and you sign off before we move to the next one.

  1. Step 1 · Audit

    Audit your existing inbound funnel

    We sit down with the teams that actually run the funnel — sales, marketing, ops — to map what's live and what's leaking. SEO positions and Core Web Vitals, citations in ChatGPT, Perplexity, Gemini and Claude, lead magnets that convert and the ones that don't, nurturing gaps inside HubSpot or ActiveCampaign, lead scoring rules. You walk away with a one-page diagnostic and the top 3 quick wins to ship this month, before we charge you a euro for execution.

  2. Step 2 · Keyword + intent map

    Map every keyword to a buyer-intent stage

    Every keyword in your space gets sorted into one of four funnel stages — awareness, consideration, decision, retention — and one search intent — informational, navigational, commercial, transactional. The map drives the content backlog for the next 6 to 12 months, so we never publish another generic blog post that brings traffic with zero buying intent. You see the spreadsheet, you approve the priorities, we ship in the order that pulls revenue first.

  3. Step 3 · Content factory

    Spin up the AI-first content factory

    Brief and outline produced in-house from the keyword map and the search intent. First draft generated through Claude or ChatGPT calibrated on your tone of voice (we load your editorial charter into the system prompt). Systematic human rewrite — 50 to 70% of the text revised — by a writer specialized in your industry, then SEO on-page optimization, structured FAQ in JSON-LD, internal linking pass. Cadence at full speed: 10 to 40 long-form articles per month, every one of them shipped to rank on Google AND to get cited inside the AI answer engines.

  4. Step 4 · Automation layer

    Wire the automation that does the heavy lifting

    Make or n8n orchestrates the full lifecycle. Lead magnet captured on a Tally or Unbounce landing page, contact enriched via Apollo and Phantombuster, AI scoring runs on the content consumed and the company signals, the lead is routed to sales only when the warmth threshold is crossed. Every nurturing email generated dynamically by an LLM with the contact's real-time context. The system runs 24/7, no SDR babysitting it, no SLA missed because someone forgot to forward a Slack notification.

  5. Step 5 · Dashboard + iteration

    Run the dashboard, iterate every single month

    Six KPIs reported in a shared dashboard you check whenever you want: total organic traffic, top-10 and top-3 positions on strategic keywords, citations in ChatGPT, Perplexity, Gemini and Claude, leads generated per source, conversion rate lead→MQL→SQL→customer, CAC per channel and LTV per cohort. We move the underperforming levers every month — new article batches, refreshed lead magnets, A/B tests on landing headlines, automation tweaks. No vanity metrics. No quarterly slide deck. Monthly iteration on what actually compounds revenue.

FAQ · inbound 2026

The 10 questions we get asked on every call.

  • What's the difference between inbound and outbound marketing?
    Outbound is you chasing the prospect: cold email, cold call, LinkedIn outreach, interruptive ads. Inbound is the opposite: you create the conditions for the prospect to come to you through organic search (SEO + AI SEO), content, lead magnets, and nurturing. Both work and complement each other. Inbound has a better ROI at 12-18 months. Outbound delivers faster at 1-3 months but costs more in headcount and saturates the channel.
  • How much does an inbound marketing agency cost in 2026?
    Depends on scope. One-off mission (audit, SEO overhaul) runs $3,000 to $15,000 depending on depth. Monthly retainer (SEO + content + automation orchestrated) starts around $3,000-$5,000/month for SMBs, up to $15,000-$25,000/month for mid-market with high volume. Watch out for agencies that quote blind without an audit, or bill by deliverable without checking pipeline impact. Our approach: free audit first, then a quote aligned with your real targets.
  • Is an inbound agency worth it vs HubSpot alone?
    HubSpot is a tool. An agency is a team. You can buy HubSpot Marketing Hub at $800/month and underuse it at 10% capacity for 3 years (we see this in 80% of audits). Or buy HubSpot and run an inbound strategy with an agency that knows how to use it. The real question: do you have someone in-house spending 30% of their time on inbound, fluent in SEO + AI SEO + content + automation + analytics? If yes, the tool alone is enough. If not, the agency builds the system and hands you the keys.
  • How long until inbound shows results?
    Honest answer: 3-6 months for the first measurable results (growing organic traffic, first leads via lead magnets), 9-12 months for the system to hit cruise altitude and produce a steady flow. Inbound isn't paid: you're not buying clicks, you're building an asset that appreciates over time. At month 1 you have nothing to show. If you need results in 30 days, run paid + cold outreach in parallel first. Inbound takes over at 6-12 months and brings your blended CAC down.
  • Is AI SEO actually important or just a buzzword?
    Important. Measurable. Google AI Overviews now hit 70% of informational queries in the US in 2026, ChatGPT Search crossed 200M weekly users, Perplexity handles 15M queries/day. On technical B2B queries, 30-50% of Google traffic has already shifted to generated answers that don't click out. Ignoring AI SEO in 2026 is exactly like ignoring mobile in 2014: you lose leads without seeing them. Method is moving (LLM algorithms shift every 2-3 months), so you need an agency that adapts faster than you do.
  • Does inbound work in B2B or only B2C?
    Better in B2B, actually. The inbound logic (long sales cycle, prospect researching before buying, multi-stakeholder decisions) fits B2B perfectly. The average B2B purchase is preceded by 3-7 pieces of content consumed before the first sales touch (HubSpot State of Sales 2025). In B2C consumer impulse purchase, inbound has less grip and paid + community marketing perform better. In B2C considered purchase (SaaS, finance, real estate), inbound stays relevant.
  • How do you measure ROI on an inbound mission?
    We track 6 main KPIs measured monthly and reported in a shared dashboard: total organic traffic, positions on strategic keywords (top 10, top 3), citations in AI engines (ChatGPT, Perplexity, Gemini), leads generated by source, conversion rate lead→MQL→SQL→customer, CAC per channel and LTV per cohort. No vanity metrics unless they serve a direct business goal. Monthly iteration on underperforming KPIs.
  • Which CRM do you work with? We already have one.
    We stay tool-agnostic. We've shipped inbound stacks on HubSpot, Pipedrive, Salesforce, Attio, Folk, Airtable, and custom CRMs built on Supabase. As long as your CRM has a documented API and webhooks, we plug it into the inbound stack via Make or n8n. The choice depends on your budget, sales team size, existing data. We don't force a migration if your current CRM is doing the job.
  • Do you produce content in-house or outsource it?
    Hybrid, with a structured human + AI workflow. Brief and editorial strategy produced in-house (keyword research, search intent, article outline). First draft generated via Claude or ChatGPT with a system prompt calibrated on your tone of voice. Systematic human rewrite (50-70% of the text revised) by a writer specialized in your industry. Final proofread, on-page SEO optimization, integration. Output rate: 10-40 long-form articles per month. No raw AI content published without human review. House rule.
  • How long do we commit for?
    Three formats. One-off audit: flat fee, 1-3 weeks, deliverable is the action plan. Implementation sprint: 3 months, we deploy the stack and the first sequences, then hand over the keys. Ongoing retainer: 6-month minimum (inbound doesn't deliver in month 1, we won't bill for nothing), then monthly cancellation. No forced annual contract, no convoluted exit clauses, no 12-month minimum 'because that's industry standard.' If we don't deliver, you stop.
