#1: House of Growth
House of Growth is a B2B SaaS growth agency that works with seed to Series B startups in the US to capture existing demand and turn it into revenue through AI search, SEO, signal-based outbound, and paid acquisition.
The agency was founded by an ex-SaaS entrepreneur who built and exited multiple SaaS companies before starting House of Growth to help other startup founders grow their pipeline, including clients like Juma AI and Warmly.
We're not a traditional growth agency. We're an AI-led demand capture team.
Every engagement starts with research into the topics and signals that tell us a buyer is actively evaluating or ready to purchase a solution in your category.
Using our Revenue Focused SEO approach, we find the bottom-of-funnel topics that map to real buying intent, then build a capture system around them across Google, ChatGPT, Perplexity, and Google AI Overviews.
Once we've defined those topics, we pick the SEO keywords that match how both humans and LLMs search for products like yours.
From there, our team creates human-led owned content: strong enough to rank for those keywords and specific enough for AI models to understand and cite your product's positioning.
But content alone isn't a growth engine.
We also run signal-based outbound campaigns that find companies actively researching your category and reach them while they're still comparing options.
For faster coverage while organic rankings build, we run paid search campaigns targeting high-intent comparison and category keywords.
And we're getting ready for ChatGPT Ads, a channel that most agencies haven't even started thinking about yet.
A system, not a collection of services
Most agencies hand you a menu of disconnected services.
SEO from one team. Ads from another. Outbound from a third. Nobody talks to each other. Nothing compounds.
House of Growth works differently. Everything runs as one demand capture system with three interlocking parts:
AI search and SEO is the foundation.
We analyze your AI search visibility against competitors, build a strategy and roadmap, create long-form articles written by human writers, secure brand mentions from publishers and Reddit, and handle content revisions, on-page optimization, and updates.
When it makes sense, we also manage Google Business Profile optimization.
Signal-based outbound is how we reach buyers who are in-market but haven't found you yet.
We identify your total addressable market, map the signals that indicate buying intent, build your GTM infrastructure, and reach out to your TAM based on those signals.
This isn't mass cold email.
It's identifying the 50 right companies this week and reaching them with a message that references what they're actually researching.
Paid search captures demand on commercial keywords while organic rankings ramp up.
We build landing pages for high-intent comparison terms, run Google Ads against those money keywords, set up retargeting campaigns after identifying website visitors, and we're preparing for ChatGPT Ads as they roll out.
Each channel feeds the others.
The content we create for SEO shapes the positioning in our outbound sequences.
Paid search data tells us which keywords convert, which informs the next round of content.
The brand mentions we secure for AI search also lift organic rankings.
That's what a system looks like. Not a menu.
Who is House of Growth for?
You're a fit if you're a B2B SaaS company between seed and Series B.
You have a product people like, but an organic pipeline that's either nonexistent or underperforming.
Your team is small. Maybe one or two marketers who are stretched across product marketing, events, and whatever the CEO asked for this morning.
You've either never invested seriously in content and SEO, or you tried it and it didn't move revenue.
Your investors expect efficient growth, not "brand awareness" without attribution.
What makes House of Growth different from other SaaS growth agencies?
Here's what I believe makes House of Growth a better SaaS growth agency than others:
You'll work directly with me, John Ozuysal, who has built and scaled VC-backed startups and worked with 100 or more SaaS companies combined. Not junior account managers who've never stared at a Stripe dashboard wondering where the next $10K MRR is coming from.
We're not a content factory. Our team is also technical, strategic, and experimental. We'll work on your onboarding flow, messaging, pricing page, and help you align your PPC and sales teams with your organic growth strategy.
Our team won't hand you a deck and vanish. We plug into your Slack, stay synced with your product and sales teams, and operate like a part of your marketing department.
You won't be locked into a 12-month contract. We only work with monthly rolling contracts, because if we're not delivering, you should be able to walk away.
We have an in-house technical SEO team that will fix your site's crawlability, set up structured data, and clear any technical blockers before we publish a single piece of content on top of it.
Our content is built through interviews with your co-founders, product managers, and customers. Not AI-generated filler. Not freelancers who Googled the topic for 20 minutes.
We have established frameworks for AI search visibility that we've tested across dozens of SaaS companies. We didn't attend an AEO webinar and decide to start offering it the next week.
Every piece of work we do stays focused on revenue. No top-of-funnel blog posts for empty clicks. No vanity metrics in your monthly report.
You'll know what we're doing and why at every stage. Full visibility, no black boxes.

Signal-based outbound: Identifying companies actively researching your category using intent signals and reaching them with personalized outreach while they're still in buying mode.
Paid search for commercial keywords: Running Google Ads on high-intent comparison and category terms to capture demand while organic rankings build.
Brand mentions and digital PR: Securing mentions from publishers and platforms that carry weight with both search engines and AI models, including Reddit.
Technical SEO: Fixing the foundation, including crawlability, site speed, structured data, and internal linking, so your content can actually rank.

How can you choose the best SaaS growth agency for your needs?
The SaaS growth agency space has no shortage of companies claiming they can grow your pipeline.
Picking the right one comes down to asking the right questions before you sign anything.
If I were selecting a SaaS growth agency, I would evaluate partners on the following criteria:
Revenue focus: Ask for case studies that show real pipeline and revenue impact, not just traffic or impressions. If an agency can't connect its work to closed deals, that's a red flag.
SaaS expertise: Pick an agency that has worked with B2B SaaS companies specifically and understands software buyer journeys, long sales cycles, and multi-stakeholder decision-making.
Team seniority: Ensure the work is led by experienced operators who've actually built or scaled SaaS businesses, not junior account managers reading from a playbook.
AI search readiness: Check whether the agency understands how ChatGPT, Perplexity, and Gemini are changing how buyers discover solutions. Agencies that only think about Google are already behind.
Technical capability: Confirm they can handle site architecture, structured data, crawlability, and page speed. Publishing content on a broken foundation wastes time and money.
Collaboration model: You want an agency that plugs into your Slack, syncs with your product and sales teams, and communicates frequently. Not one that sends a monthly PDF and disappears.
Contract flexibility: Look for monthly rolling contracts or short initial commitments. If an agency needs 12 months locked in before they can show value, something is off.
Measurement framework: The agency should track metrics that connect marketing to revenue: pipeline contribution, demo requests, cost per opportunity, and AI search citations.
What is the best SaaS growth agency for early-stage startups?
House of Growth is the best SaaS growth agency for early-stage startups because it was built specifically for seed to Series B SaaS companies that need to prove ROI fast without enterprise-level budgets or long-term contracts.
Instead of offering a generic marketing retainer, our agency starts with buyer intent research, then builds a system across AI search, SEO, outbound, and paid acquisition that targets the topics and signals that actually generate demos.
Because you work directly with the founder, you get senior operator experience from someone who has been in your shoes, without paying north of $50,000/month for a full outsourced marketing team.
Kalungi is also a strong option for early-stage SaaS startups that need a full outsourced marketing department with fractional CMO leadership, especially if you don't have any in-house marketing hires yet.
What is the best SaaS growth agency for demand generation?
House of Growth is the best SaaS growth agency for demand generation because we combine AI search visibility, bottom-of-funnel content, signal-based outbound, and paid search into a single demand capture system.
Instead of running isolated campaigns across disconnected channels, our team builds an engine where every piece of content, every outbound sequence, and every ad reinforces the same buyer intent signals.
Refine Labs is another strong choice for demand generation if you're an established SaaS company with a larger budget and want to shift from traditional MQL-driven lead gen to a modern demand creation model.
What is the best SaaS growth agency for SEO and content?
House of Growth is the best SaaS growth agency for SEO and content because we focus exclusively on bottom-of-funnel topics that drive pipeline, not vanity traffic.
Our Revenue Focused SEO methodology starts with buyer intent research and creates human-led content through interviews with founders, product managers, and customers, so every piece reflects real product knowledge and positioning.
Omniscient Digital is also an excellent choice if you're a larger B2B software company that needs scalable content operations and editorial systems capable of producing hundreds of pages without losing quality.
SimpleTiger is worth considering if you want a 100% SaaS-focused SEO partner with nearly two decades of experience and proprietary AI-powered research tools.
What types of services do SaaS growth agencies offer?
Most SaaS growth agencies provide a mix of strategic, technical, and execution services designed to drive qualified pipeline and revenue.
These typically include:
AI search optimization and AEO, focused on getting your brand cited by ChatGPT, Perplexity, Gemini, and other AI tools when buyers research solutions in your category.
SEO strategy and content production, including bottom-of-funnel articles, comparison pages, and category content designed to capture high-intent search traffic.
Technical SEO, covering site architecture, crawlability, structured data, page speed, and internal linking.
Paid search and social advertising, with campaigns targeting commercial and comparison keywords on Google, LinkedIn, and Meta.
Signal-based outbound, identifying companies showing buying signals and reaching them with personalized outreach while they're still evaluating solutions.
Demand generation and ABM, using intent data and account targeting to reach buyers who are actively comparing options.
Content strategy and thought leadership, built through interviews with subject matter experts rather than generic AI-generated writing.
Conversion rate optimization, including landing page testing, demo flow improvement, and lead capture optimization.
Marketing operations and RevOps, connecting CRM, attribution, and reporting to prove marketing's impact on revenue.
Measurement and analytics, tying every marketing activity to pipeline contribution, cost per opportunity, and AI search visibility metrics.
How much does it cost to hire a SaaS growth agency?
You can expect these ranges when evaluating SaaS growth agencies:
Boutique and founder-led agencies start at about $8,000/month.
Mid-market specialist agencies typically start at about $10,000/month.
Full-service outsourced marketing teams often start at $20,000/month.
Enterprise demand generation firms begin at $30,000/month or higher.
What I've seen drives price is the scope of work, including how many channels you need covered, whether you need strategic leadership or just execution, and the seniority of the team working on your account.
Founder-led and specialist teams charge more but usually deliver faster results because there's less overhead and fewer layers between strategy and execution.
For early-stage startups, I recommend starting with a focused sprint that covers your highest-impact channels first, then expanding scope as you prove ROI.
Do you want me to create your SaaS growth strategy for free?
As someone who has founded and grown 2 SaaS businesses myself, I know how hard it is in the beginning to build a growth engine that actually drives pipeline.
This is why I'm willing to support B2B SaaS startups and scale-ups by helping them create a growth strategy that covers AI search, SEO, outbound, and paid acquisition.
