When Series A-C B2B SaaS companies evaluate marketing partners, the choice often comes down to three distinct approaches: full-service agency teams, specialized demand generation firms, or focused product marketing consultants. Kalungi, 42/Agency, and Genesys Growth represent these three models. Each operates with a different philosophy on how to accelerate B2B SaaS growth. I built Genesys Growth to deliver senior-level execution at startup speed: an embedded operator who ships positioning, landing pages, content, and launches 3X faster through AI-enabled workflows. Series A-C companies benefit from focused, embedded expertise when they already have internal marketing foundations.

Key Takeaways

• I complete positioning sprints in 15 days, far faster than the 4 to 8 weeks many published B2B positioning sprint timelines require, and ship production-ready messaging frameworks, sales decks, and homepage copy in a single engagement

• I work directly with every client. No account managers, no junior staff handoffs, no game of telephone

• My AI-native workflows transfer to clients as their own assets, building long-term independence rather than consultant dependency

• I keep client time commitment to 2-3 hours weekly, a lean model that respects how stretched founders and marketing leaders already are

• My case studies document outcomes like 175K impressions from programmatic SEO in 2 months and $600K pipeline influenced through founder-led content programs

Understanding each company's core positioning

Kalungi positions itself as a complete marketing department replacement for B2B SaaS companies. Founded in 2018 and headquartered in Seattle, third-party directories list the agency in the 51-200 employee range, with LeadIQ estimating about 57 employees as of 2026. Kalungi built its reputation on the T2D3 methodology. The model assigns dedicated team members led by a fractional CMO.

42/Agency takes a performance-first approach from its Toronto base. With 11-50 employees, the agency focuses on demand generation, marketing operations, and RevOps.

Genesys Growth is the consultancy I founded in 2022 after over a decade of hands-on B2B SaaS marketing experience. I deliver specialized product marketing and content consulting as an embedded operator. Rather than build a large team or focus on a single channel, I give clients direct access to senior expertise with weekly deliverables. I've served 45+ B2B SaaS startups including public companies like Toast and high-growth ventures like Ahrefs and Common Room.

The fundamental difference: Kalungi builds marketing departments from scratch, 42/Agency runs paid channels, while I embed as a senior operator who delivers positioning that ships as landing pages, content, launches, and pSEO.

Service offerings reveal strategic focus differences

Kalungi's service portfolio spans content marketing, paid media, account-based marketing, SEO, marketing automation, web design, HubSpot configuration (they're a HubSpot Diamond Partner), and fractional CMO leadership. This broad approach fits companies starting marketing from zero, but it creates coordination overhead for teams that already have a marketing function.

42/Agency's services concentrate on paid media, ABM, RevOps, attribution, SEO, and creative for campaign assets. Their focus is on performance metrics like SQL and CAC. Companies with unresolved positioning may find dedicated upstream messaging work a useful complement to performance channel investment.

My services target high-impact areas that directly influence GTM outcomes. I deliver six clearly defined plans with transparent pricing:

• Positioning Sprint Plan ($15,000, 2 weeks): win/loss analysis from sales calls, deep competitor research and ICP definition, positioning anchor strategy and messaging library, sales deck articulating positioning, and a homepage wireframe with production-ready copy. Tools: Figma, Claude. (Pricing details)

• Website Expansion Plan ($12,000/month, 3-month minimum): context engineering across ICP, product, market, and TOV; core pages (Home, Features, Pricing, About), persona pages, use case pages, integration pages, competitor comparison pages, and ad-hoc landing pages. Tools: Figma, Clay, Claude, Webflow.

• Product Launch Plan ($15,000, 45-day sprint): launch strategy and narrative, landing page and sales deck updates, LinkedIn post series, blog/email/webinar announcements, in-app touchpoints, and creator amplification.

• Storytelling Sprint Plan ($8,000/month, 3-6 month minimum): narrative development using the Hero's Journey, audience archetype creation, anchor content series, dedicated microsite, customer video briefs, and webinar program.

• Founder-Led Content Plan ($8,000/month, 6-month minimum): content strategy and pillars, LinkedIn profile optimization, 3-5 LinkedIn text posts per week, 2 infographic wireframes per week, and community engagement guidelines.

• Sales Enablement Plan ($8,000/month, 2 months): sales deck copy articulating positioning, case studies from call transcripts, competitor comparison pages, competitor battlecards, and ROI calculators.

Additional service areas include messaging and positioning through AI-enabled customer and competitor analysis, website optimization delivering 34+ landing pages in single engagements, Product launches completed in 45-day sprints, Founder-led content programs generating million-plus impressions, lifecycle marketing campaigns across activation and retention, and programmatic SEO at scale. Common Room received 650+ pSEO pages generating 175K impressions in 2 months.

The specialization allows for deeper expertise and faster execution. I deliver complete messaging frameworks in 15 days and website overhauls in 2 weeks.

Target customers and ideal use cases

Kalungi serves B2B SaaS companies across multiple growth stages through distinct service tiers. Their Syntropy program targets early-scale ventures under $2.5M ARR. Their Full Service offering is designed for post-PMF companies in the $5M to $50M ARR range. Their T2D3 framework is available as a self-directed resource for earlier-stage teams.

According to their current contact page, 42/Agency primarily works with Series A-C B2B SaaS companies or those with $5M+ in revenue, typically with existing product or content marketing or a Head/VP of Marketing in-house.

I focus on Series A-C B2B SaaS companies in AI/ML Infrastructure, DevTools, and GTM/Sales Tech that have achieved product-market fit and typically have 0-2 marketers in-house. These organizations need senior PMM expertise to refine positioning, accelerate content production, and ship strategic initiatives without project-managing designers and copywriters. Clients I've worked with include:

• Public companies: Toast, Fiverr

• Late-stage ventures: Ahrefs, Common Room, Owner.com

• Growth-stage startups: Strapi, Octave, Platformatic

The distinction matters. Series A-C companies benefit from a senior operator who runs strategy and ships execution autonomously. My embedded model fits these needs, with engagements averaging 5-8 months as a senior partner inside the team.

Results and case studies demonstrate execution speed advantages

Kalungi's case studies include published outcomes for clients such as Zippity and DataGuard, with results compounding across a multi-month engagement timeline.

42/Agency's case studies focus on paid channel efficiency metrics across clients including Cin7, Charma, and Smile.io.

My results showcase rapid execution and strategic impact:

• Strapi: 34+ landing pages with landing page creation and product launch processes running 3X faster while maintaining a high quality bar

• Platformatic: 1M+ LinkedIn impressions and $600K pipeline influenced

• Common Room: 40+ pages plus 650+ programmatic SEO pages generating 175K impressions in 2 months

• Ahrefs: Full messaging audit and repositioning completed in 15 days

• Meaningful outcomes delivered in weeks, not months

Speed matters for Series A-C companies facing competitive pressure. Waiting many months for results to compound can mean ceding ground to faster-moving competitors who ship and learn faster.

Methodology and approach define the engagement experience

Kalungi's methodology centers on their T2D3 framework and full-service team deployment. The model assigns specialists across marketing functions, with a fractional CMO providing oversight and coordination.

42/Agency's approach focuses on demand generation, RevOps, paid media, and campaign systems. Companies with unresolved messaging or positioning may benefit from deeper upstream strategic work before scaling acquisition spend.

My approach embeds me as a senior operator inside the client team, working with AI-native workflows. I personally handle every engagement from kickoff to delivery. Clients get direct access to senior expertise without layers of account management.

Key elements of my methodology:

• Context engineering methodology: Deep customer research (ICP analysis, competitor intelligence, voice-of-customer data) becomes positioning that compounds across every GTM touchpoint

• Proprietary AI tools: Custom MCP servers, prompt libraries, and workflows using Claude, Perplexity, Clay, n8n, and Octave

• Workflow transfer: Clients own the AI tools and methodologies after the engagement, not perpetual dependency

• Weekly deliverables: Continuous progress with always-on Slack communication

• Low client burden: Only 2-3 hours weekly compared to the coordination demands of multi-specialist agency models

The execution philosophy difference is stark: Kalungi builds marketing departments over months, 42/Agency builds paid channel systems, while I ship strategic wins in weeks.

Team structure and expertise concentration

Kalungi's team structure is listed by third-party directories in the 51-200 employee range, with LeadIQ estimating about 57 employees as of 2026. The multi-specialist team operates with an Associate CMO managing specialists as the primary client point of contact.

42/Agency's structure has 11-50 team members. Clients are assigned a pod with a demand strategist, specialist, and designer.

My structure is a lean, focused embedded-operator model:

• I'm directly involved on every engagement, no account management layers

• 10+ years of concentrated B2B SaaS experience

• Single relationship from kickoff to delivery

• Consistent quality through personal execution

• Deep expertise in technical markets and buyers

Series A-C companies benefit from deep, senior expertise rather than coordinated specialist coverage. Working directly with me eliminates the game of telephone that often slows down larger agency engagements.

Why Genesys Growth fits Series A-C SaaS companies

Series A-C B2B SaaS companies face challenges that fit my model precisely. These companies need positioning clarity, execution speed, and a senior operator who ships, not advice.

Speed that matches startup velocity

I complete positioning sprints in 15 days, far faster than the 4 to 8 weeks many published B2B positioning sprint timelines require. The Website Expansion Plan delivers core pages, persona pages, use case pages, integration pages, and competitor comparisons within a 3-month engagement. Velocity matters in competitive markets where first-mover advantages determine category leadership.

Transparent pricing across six plans

My pricing is published openly across six clearly defined plans:

• Positioning Sprint: $15,000 (2 weeks)

• Website Expansion: $12,000/month (3-month minimum)

• Product Launch: $15,000 (45-day sprint)

• Storytelling Sprint: $8,000/month (3-6 month minimum)

• Founder-Led Content: $8,000/month (6-month minimum)

• Sales Enablement: $8,000/month (2 months)

This pricing brings Director-level product marketing expertise at a fraction of a full-time PMM hire fully loaded, with minimum commitments as short as 2 weeks for sprint work.

AI-native methodology you own

My AI workflows transfer directly to clients. Custom prompt libraries, context engineering frameworks, and automation workflows become client assets, building long-term independence rather than consultant dependency. Clients receive AI prompt libraries and automation workflows built around their unique context, and take full ownership when the engagement concludes.

Direct access eliminates friction

When you work directly with me, you get strategic alignment and rapid iteration. Testimonials consistently emphasize "lightning speed" (Eoin Clancy, AirOps), "blazing fast" (Martin Gonto, HyperGrowth Partners), and work completing "way faster than I had imagined" (David Fallarme, Owner.com). Victor Coisne, VP Marketing at Strapi, put it this way: "Matteo's AI chops in marketing are what sets him apart from other consultants. He knows which AI to use, when and how to use them, and made our landing page creation and product launch processes 3X faster, all while keeping a high quality bar."

Technical market expertise

I bring specific credibility with developer tools and technical B2B products. I've repositioned complex platforms like Strapi (headless CMS), Platformatic (Node.js microservices), and AirOps (AI workflows). Zach Vidibor, CEO of Octave, put it this way: "Matteo lives and breathes GTM tech. He knows how to break down complex concepts, explain and position them well."

For Series A-C B2B SaaS companies seeking marketing acceleration with senior expertise and AI-enabled speed, I'm the embedded operator model that ships positioning, content, launches, and pipeline week after week.

Frequently Asked Questions

What types of B2B SaaS companies benefit most from Genesys Growth versus Kalungi or 42/Agency?

I work best with Series A-C B2B SaaS companies in AI/ML Infrastructure, DevTools, and GTM/Sales Tech that have achieved product-market fit and have 0-2 marketers in-house. These companies need senior PMM expertise to refine positioning, accelerate content production, and ship strategic initiatives. Ideal clients include venture-backed startups preparing for growth rounds, companies entering new markets or launching major products, and organizations refining messaging without overhauling their entire marketing function. Kalungi serves multiple stages: their Syntropy program suits early-scale ventures under $2.5M ARR, while their Full Service model targets post-PMF companies in the $5M to $50M ARR range. 42/Agency primarily works with Series A-C companies or those with $5M+ in revenue that have existing marketing leadership.

How do engagement timelines differ between these three options?

I operate on accelerated timelines. Positioning sprints complete in 15 days, website expansion plans run for 3-month minimums, product launches finish in 45-day sprints, sales enablement engagements run for 2-month minimums, and founder-led content programs require a 6-month minimum commitment. Kalungi describes a multi-month timeline for full results to compound. 42/Agency timelines vary by campaign scope and align with standard agency cycles. For Series A-C companies facing competitive pressure, my rapid execution model delivers meaningful outcomes in weeks rather than months.

How does your AI-native approach differ from what agencies offer?

I systematically apply proprietary AI workflows including custom MCP servers, prompt libraries, and tools like Claude for copy generation, Perplexity for competitive research, Clay and n8n for workflow automation, and Octave for messaging hubs. Critically, these workflows transfer to clients as their own assets. Clients receive custom prompt libraries and automation workflows built around their specific context, and take full ownership after engagements conclude. This is what "AI-native" looks like in practice: AI accelerates research, drafting, and iteration, while I QA every output and own the strategy.

What should I expect in terms of time commitment working with each option?

I keep client time commitment to only 2-3 hours weekly: strategic sessions plus async Slack communication. Kalungi's Full Service model estimates 2 to 5 hours weekly for executive reviews, syncs, and alignment. 42/Agency describes pods, Slack, and sync calls but does not publish a specific weekly-hour estimate. For founders and marketing leaders already stretched thin, my lean async model lets you stay focused on product and customers while marketing keeps shipping in the background.

Can I use Genesys Growth alongside another agency for different functions?

Yes. My focused embedded-operator approach on positioning, content, and product marketing complements specialized agencies handling paid media or demand generation. A common pattern: I own upstream strategic work (positioning, messaging, content programs, launches, pSEO) while performance marketing specialists handle paid channel execution. This sequence ensures strong positioning and messaging foundations before scaling acquisition spend, so paid channels promote a clear, differentiated story rather than amplifying generic messaging. My partner network includes specialists across design, SEO, and GTM engineering for seamless collaboration.
