When B2B SaaS companies reach Series A and beyond, choosing the right growth partner becomes a defining decision. Three names represent distinct approaches: Genesys Growth, Single Grain, and Refine Labs. I run Genesys Growth as a product marketing consulting practice with AI-native execution for Series A-C B2B SaaS. Single Grain is a full-service digital marketing agency. Refine Labs works with mid-market and enterprise companies on demand generation. This comparison shows why Genesys Growth's focused methodology fits Series A-C B2B SaaS companies that need strategic positioning and rapid execution. You get an embedded senior operator who ships, not open-ended retainers or frameworks built for mid-market and enterprise companies.

Key Takeaways

• I complete a positioning sprint in 2 weeks at $15,000, while Single Grain operates as a full-service digital marketing agency and Refine Labs serves mid-market and enterprise companies

• For Series A-C B2B SaaS companies, my AI-native workflows deliver 34+ landing pages (Strapi) or 650+ programmatic pages (Common Room) in timeframes traditional agencies can't match

• Single Grain is a full-service digital marketing agency working across channels

• Refine Labs serves mid-market and enterprise companies with demand transformation programs, a different stage from early-growth B2B SaaS startups

• I give clients direct access to senior expertise as the founder, Matteo Tittarelli, with no coordination overhead from large agency teams

B2B Marketing & Growth Agencies: Core Focus and Methodology

Each firm brings a different philosophy to B2B growth.

Genesys Growth is the B2B SaaS product marketing and content practice I founded as Matteo Tittarelli. I embed as a senior GTM operator on strategic messaging, go-to-market architecture, and product marketing for Series A-C companies. I've served 45+ startups, including Toast, Ahrefs, and Common Room, delivering positioning that ships as production-ready assets, not decks, through hands-on execution rather than agency teams.

Single Grain is a full-service digital marketing agency that works across multiple channels.

Refine Labs works with mid-market and enterprise B2B companies on demand generation transformation.

The core distinction: Genesys Growth builds the strategic positioning and messaging foundation that makes channel execution effective, Single Grain executes across channels, and Refine Labs works with mid-market and enterprise demand organizations.

SaaS Marketing Agility: Speed, AI, and Full-Stack Capabilities

Speed separates winners from also-rans in competitive B2B SaaS markets. Here's where each firm stands.

My AI-native methodology delivers fast execution:

• Positioning Sprint Plan: win/loss analysis, deep competitor research and ICP definition, positioning anchor strategy and messaging library, sales deck, and homepage wireframe with production-ready copy in 2 weeks for $15,000

• Website Expansion Plan: context engineering, core pages, Solutions, Personas, Use Cases, Integrations, and competitor comparison landing pages at $12,000/month

• Tools I deploy include Claude for copy, Perplexity for competitive research, and Octave for messaging hubs

The Strapi engagement shows the tempo: 34+ landing pages delivered with processes running 3X faster while keeping a high quality bar. At Common Room, I produced 650+ programmatic SEO pages generating 175K impressions in 2 months.

Single Grain runs ongoing channel campaigns as a full-service agency.

Refine Labs centers on demand strategy for mid-market and enterprise companies. Its Clari engagement unfolded over roughly 9 months, reflecting an organizational change focus rather than rapid tactical execution. Public sources do not establish 9 months as an average engagement length.

For Series A-C companies facing competitive pressure, a complete positioning framework delivered in 2 weeks, not a multi-month agency ramp, is the difference between defining your category and ceding it.

Target Market Depth: Who Do These B2B SaaS Agencies Serve Best?

Understanding ideal client profiles reveals which firm fits your stage.

I serve post-product-market-fit B2B SaaS companies from seed to public stages, with particular focus on Series A-C. My primary buyers are founders, VPs of Marketing, and Growth leaders at technical developer tools and MarTech platforms. Notable clients include Toast (public), Ahrefs (bootstrapped, 201-500 employees), and Octave (Seed, $5.5M funding).

Single Grain serves a range of industries with a full-service model.

Refine Labs positions around mid-market and enterprise B2B SaaS and tech companies. Companies at the Series A-C stage sit below that profile.

The targeting clarity matters: I focus on Series A-C B2B SaaS, the exact stage and segment where positioning that ships moves the needle.

Driving Demand & Pipeline: Demand Generation Agency Strategies

Pipeline generation approaches differ across these firms.

I drive pipeline through positioning clarity and content that compounds:

• The HyperGrowth Partners case generated $3M+ pipeline from content with 5,500 Substack subscribers built over 2 years

• Platformatic achieved $600K influenced pipeline alongside 1M+ LinkedIn impressions through founder-led content

• The Storytelling Sprint Plan at $8,000/month creates coordinated multi-format campaigns using narrative development and audience archetype creation

Single Grain runs integrated channel campaigns.

Refine Labs focuses on demand transformation for mid-market and enterprise companies.

For Series A-C companies building demand generation capabilities, I establish positioning first, then activate through content. That sequence builds more sustainable pipeline than channel-first activity on an unclear message. Automate distribution before the message is clear and you scale the wrong thing faster.

Product Marketing & Technical Expertise for B2B SaaS

Product marketing expertise separates strategic partners from execution shops.

My product marketing specialization includes:

• Product Launch Plan: 45-day sprint at $15,000 covering launch strategy, narrative, landing pages, LinkedIn series, and multi-channel announcements

• Deep experience with technical products: I repositioned complex platforms like Strapi (headless CMS), AirOps (AI workflows), and Platformatic (Node.js microservices)

• Messaging frameworks built with product positioning methodologies that translate technical capabilities into buyer value

Clients consistently point to my ability to break down complex concepts for technical markets. The Ahrefs engagement delivered a messaging audit and repositioning as a "marketing intelligence platform" in 15 days.

Single Grain is a full-service digital marketing agency.

Refine Labs focuses on demand generation and go-to-market transformation for mid-market and enterprise companies.

For B2B SaaS companies with technical products that struggle to articulate value clearly, translating what you built into why buyers care is the core of what I do. I write for technical evaluators and business buyers at the same time.

Comprehensive Digital Marketing Services: Beyond Growth

Understanding the full service scope helps set expectations.

My service portfolio focuses on high-impact strategic areas:

• Sales Enablement Plan: $8,000/month for 2 months delivering sales decks, case studies, competitor battle cards, and ROI calculators

• Lifecycle marketing systems: the Octave engagement included 15+ campaigns across activation, expansion, and churn prevention

• Programmatic SEO at scale, as shown by Common Room's 650+ page deployment

Single Grain offers channel execution across digital marketing.

Refine Labs offers demand strategy and measurement for mid-market and enterprise companies.

Genesys Growth concentrates on the strategic foundations of positioning, messaging, and product marketing that make every channel investment more effective. Strategy and execution come from one operator, so positioning, website, content, and sales materials all speak the same language.

Agency Scale, Client Portfolio, and Global Reach

Portfolio composition reveals focus.

I've served 45+ B2B SaaS startups, including companies backed by Greylock, Index Ventures, Atomico, and Y Combinator. The client base spans pre-seed to IPO with concentration in Series A-B. Geographic presence includes the US (primarily San Francisco), Europe (London, Paris, Dublin), and global remote collaboration from the UK.

Single Grain operates as a full-service agency across multiple industries.

Refine Labs works with mid-market and enterprise clients.

For Series A-C B2B SaaS companies, my concentrated portfolio in your exact stage and industry creates deep pattern recognition and directly relevant expertise.

Why Genesys Growth Stands Out for Series A-C B2B SaaS Companies

Series A-C B2B SaaS companies face challenges that make Genesys Growth the right fit. These companies don't need a complete marketing team replacement or mid-market and enterprise demand transformation. They need strategic clarity, rapid execution, and specialized product marketing expertise.

Strategic foundation before channel execution: I establish the positioning and messaging frameworks that make downstream marketing investments more effective. The Positioning Sprint Plan at $15,000 creates that foundation in 2 weeks, so you execute channels with clarity instead of spending months discovering your positioning through expensive trial and error.

AI-native velocity: My AI-native workflows, using Claude, Octave, and AirOps, deliver hundreds of assets in timeframes manual processes can't reach. The Strapi case showed processes running 3X faster while keeping a high quality bar.

Direct senior expertise without coordination overhead: You work directly with me, Matteo Tittarelli, with no account management layers or junior handoffs. Same person from kickoff to delivery. Clients describe "minimal brief" requirements and autonomous execution, with the Octave CEO calling Matteo a "one-man-army PMM/Growth Lead."

Right-sized investment with proven ROI: Structured pricing from $8,000/month gives Series A-C companies senior product marketing without an open-ended, agency-scale retainer. The HyperGrowth Partners case shows $3M+ pipeline from content, ROI that justifies the focused investment.

For Series A-C B2B SaaS companies seeking marketing acceleration through specialized expertise rather than agency overhead, Genesys Growth is the embedded operator model: positioning that ships, and keeps shipping.

Frequently Asked Questions

What makes Genesys Growth's approach unique compared to traditional agencies?

I combine three things in one engagement: AI-native execution velocity that delivers a positioning sprint in 2 weeks versus typical 4-8 week timelines, specialized product marketing expertise for technical B2B SaaS products, and direct access to senior strategy without account management layers. I deploy Claude for copy, Perplexity for competitive research, and Octave for messaging hubs, tools clients can keep using after engagements end, which builds sustainable capability rather than agency dependency.

How does Genesys Growth use AI in its marketing services?

I integrate AI throughout delivery. Claude handles copy and messaging refinement, Perplexity powers competitive research, and Octave serves as the messaging hub. AI-enabled content workflows produced the 650+ programmatic pages I delivered for Common Room. This AI-native approach lets one senior operator deliver output matching entire agency teams while keeping strategic depth and a high quality bar.

Which types of B2B SaaS companies are best suited for Genesys Growth's services?

I serve post-product-market-fit B2B SaaS companies from seed to public stages, with particular focus on Series A-C. Ideal clients are technical developer tools and MarTech platforms, companies that struggle to explain complex products simply. Good-fit signals include: recently funded and preparing for launch, wanting to reposition or expand segments, having multiple products for different personas, or needing a consistent launch muscle for regular feature releases.

Can Genesys Growth assist with both product marketing strategy and execution?

Yes. I bridge strategy and execution rather than stopping at recommendations. The Positioning Sprint Plan delivers win/loss analysis, positioning frameworks, messaging libraries, and production-ready homepage copy. The Website Expansion Plan includes wireframes with complete copy across core pages, Solutions, Personas, Use Cases, Integrations, and competitor comparison pages. The Product Launch Plan covers strategy through multi-channel execution including landing pages, sales decks, LinkedIn series, email announcements, and creator amplification. Every engagement ships tactical deliverables, not strategic documents alone.

What are the typical engagement timelines and pricing for Genesys Growth's core offerings?

I offer six structured plans: Positioning Sprint (2 weeks, $15,000), Website Expansion (3 months minimum, $12,000/month), Product Launch (45 days, $15,000), Storytelling Sprint (3-6 months minimum, $8,000/month), Founder-Led Content (6 months minimum, $8,000/month), and Sales Enablement (2 months, $8,000/month). This structure lets companies engage for specific outcomes with clear timelines rather than open-ended retainer commitments.

How does Genesys Growth measure ROI for its clients?

ROI shows up in pipeline, traffic growth, and execution velocity. The HyperGrowth Partners engagement generated $3M+ pipeline from content. Platformatic achieved $600K influenced pipeline alongside 1M+ LinkedIn impressions. Common Room's programmatic SEO produced 175K impressions in 2 months. Mixmax reached 10K+ monthly signups through PLG-optimized repositioning. These are tangible business outcomes: pipeline influenced, traffic scaled, and signups generated.
