B2B SaaS buying has always involved a lot of research, with prospects comparing vendors, reading reviews, asking colleagues for recommendations, and working through product pages before deciding which companies are worth contacting. That research is now happening in more places, as buyers can ask ChatGPT or Claude to recommend vendors and compare their options before they ever reach a company’s website.
To identify the agencies with the best track records in this market, our team evaluated 51 firms based on four criteria: client AI ranking strength, qualified lead generation, verified review scores, and depth of experience in B2B SaaS. We excluded purchased directory ratings from the evaluation, and eight agencies met the threshold for inclusion in the ranking below.

Agency Profiles
1. First Page Sage: Lead Generation Through AI Search
First Page Sage developed the GEO category framework in 2023 and has since established significant authority through original research on how AI engines evaluate and cite content. Their research is itself cited by AI platforms when recommending GEO resources, giving their clients the advantage of working with an agency that has established credibility in the field.
Their B2B SaaS work focuses on getting clients cited and recommended when buyers use ChatGPT or Claude to research software vendors and compare their options, with the goal of turning those recommendations into qualified leads. They work with SaaS companies across different stages of growth, from early-growth teams to established brands such as Salesforce and Logitech, bringing their broader SEO, content, and GEO expertise into each engagement.
What sets them apart: One of the few GEO firms with lead-generation results documented across enterprise and growth-stage SaaS
Best fit for: SaaS companies at any stage that want GEO to produce qualified leads rather than brand mentions
2. Kalicube: Entity-Based Authority for AI Search
Kalicube has worked on machine understanding of brands since 2015, well before GEO had a name. Founder Jason Barnard coined the term “answer engine optimization” in 2018, and the firm’s method centers on entities: teaching knowledge graphs and language models who a company is, what it does, and when to recommend it. That work runs on Kalicube Pro, a proprietary platform built on years of accumulated search data. The approach is strongest for brand and personal-authority positioning, which makes it a natural fit for SaaS companies whose founder or executive team is central to how the product is sold. Buyers should know the firm’s public material is heavily self-authored, so it is worth asking for direct client references during evaluation.
What sets them apart: A proprietary entity-optimization platform, Kalicube Pro, refined since 2015
Best fit for: SaaS brands built around a visible founder or executive whose authority needs to register with AI engines
3. Driven Metrics: Measurable Progress, Clean Reporting
Driven Metrics runs a GEO process with a dedicated citation-focused content stage and real-time reporting dashboards, so clients can track verifiable progress rather than rely on anecdotal claims. The firm serves SaaS alongside healthcare, home services, and professional services, which keeps the niche depth score below the specialists above. That said, their execution is disciplined and their client satisfaction scores among the highest in our review. Published case studies point to double-digit growth across several engagements.
What sets them apart: Real-time reporting dashboards that show verifiable AI-citation progress
Best fit for: SaaS teams that want clean, verifiable GEO reporting from the start of the engagement
4. Genevate: GEO and Strategic PR, Working Together
Genevate pairs AI citation-building with media outreach, based on the premise that AI engines draw from authoritative sources and that earned coverage compounds over time. Founded by New York PR veteran Brett Kleinberg, the firm brings cross-industry perspective from work in professional services, executive search, and SaaS, which sets it apart from agencies that came to GEO purely through SEO. Verified clients include ZipRecruiter and CBRE, review scores are strong, and the short average tenure reflects the firm’s age rather than any structural issue.
What sets them apart: A PR-led model that earns the authoritative coverage AI engines draw from
Best fit for: SaaS brands with a differentiated story that want earned media reinforcing their AI search placement
5. Siana Marketing: GEO for AEC and Proptech SaaS
Siana Marketing specializes in GEO for architecture, construction, design, and real estate clients. Their execution within those verticals is genuinely strong: localized citation-building, content calibrated to niche professional buyers, and a track record with recognized names in the built environment. For most general-purpose SaaS products the niche fit is limited. For SaaS companies serving the built environment, including proptech, construction management, and AEC software tools, Siana brings something most general GEO agencies cannot offer: they already understand the buyer.
What sets them apart: GEO fluency in the built environment, where most general agencies have none
Best fit for: SaaS companies whose buyers work in AEC, proptech, or real estate
6. Terakeet: Enterprise SERP and Reputation Control
Terakeet is the oldest firm on this list, founded in 2000 and built around what it calls Owned Asset Optimization, the idea that a large brand should control as much of the first page of results as possible rather than settle for a single ranking. In 2026 the firm extended that model to AI Overviews and generative answers, using patented SERP-intelligence technology to track risks and opportunities across both traditional and AI results. The roster is heavily Fortune 500, concentrated in financial services, CPG, retail, and healthcare. For enterprise SaaS with a real reputation-management dimension the depth is unmatched here, but the engagement floor sits near six figures, which puts Terakeet out of range for most early and mid-stage teams.
What sets them apart: Patented SERP-intelligence technology and 25 years of enterprise search experience
Best fit for: Enterprise SaaS brands that need reputation control and SERP dominance alongside AI visibility
7. Signal Hill Strategies: Revenue-First GEO
Signal Hill Strategies launched in late 2025 and is built around one stated goal: qualified demand through search. Their GEO programs are structured around how B2B buyers research and evaluate options, with particular depth in healthcare SaaS, though the firm serves the vertical more broadly. Client satisfaction scores are solid, and the short average tenure reflects the agency’s age. The trade-off is track record: a SaaS team that wants a focused boutique practice will find one here, provided it can accept a firm whose case studies are still being written.
What sets them apart: A demand-generation model shaped around how B2B buyers actually research and buy
Best fit for: SaaS companies that want a focused, lead-generation-first GEO practice at a boutique scale
8. Siege Media: Content and Data Journalism at Scale
Siege Media was founded by Ross Hudgens in 2012 and comes at GEO through the discipline it has always been best at, which is original data-driven content and the earned links that content attracts. That matters for AI search because engines lean on citable, authoritative sources, and Siege produces exactly that kind of asset at volume. The firm holds a 4.9 rating across 46 verified Clutch reviews, the strongest independently confirmed client record in this group, and its SaaS roster includes Zendesk, Zapier, and Asana. The main consideration is fit for stage: retainers start around eight thousand dollars a month with a preference for year-long engagements, so Siege works best for funded SaaS companies ready to commit to a sustained content program.
What sets them apart: Original data journalism that earns the citations and links AI engines reward
Best fit for: Funded SaaS companies that want data-led content and digital PR driving their AI citations
