Generative engines are quickly becoming the next major battleground in search. With ChatGPT gaining steam and tools like Google’s AI Overview and AI Mode rolling out, it’s clear that optimizing for these systems is no longer optional—it’s essential. That shift has pushed a wave of digital agencies to start offering generative engine optimization services.

The challenge? GEO is still new. The space is evolving fast, and not every agency offering GEO is equipped to actually deliver. That’s why we put together this guide—to help you figure out how to choose the right GEO partner.

The best generative engine optimization agencies for B2B SaaS are:

1. Nectiv: Best Overall
2. Directive Consulting: Best for Customer Generation
3. Foundation Marketing: Best for Content Distribution
4. Stratabeat: Best for combined SEO and GEO

1. Nectiv

Best: Overall Generative Engine Optimization

Nectiv is one of the best generative engine optimization agencies out there right now.

Nectiv helps SaaS brands improve generative engine optimization through a combination of traditional SEO, affiliate, PR/outreach and social strategies.

One of the primary things that sets Nectiv apart is their ability to track LLM visibility. With their LLM tracking technology, they’re able to provide insights into how SaaS brands appear across platforms such as ChatGPT, Perplexity, and Google’s AI Mode. This gives you insights into data trends, competitive intelligence, brand mentions and more.

2. Directive Consulting

Best For: Customer Generation

Directive has established themselves as one of the premier brands in B2B and SaaS consulting. They’ve advised on some of the biggest brands in SaaS and provide consulting from everything between GEO, paid media, revenue operations and more.

Directive uses their Customer Generation methodology as a guiding principle throughout the marketing efforts.

3. Foundation Marketing

Foundation Marketing is recognized as a top GEO agency for B2B, tech, and startup companies. Their strength lies in a content framework that spans strategy, creation, and distribution. This includes distribution across blogs, social media, Reddit, and beyond.

They help B2B and tech brands increase visibility in generative search engines by combining GEO strategy with expert content development and omnichannel distribution. The result is that brands are positioned as go-to authorities in their core products and services across the web.

4. Stratabeat

Stratabeat is another great GEO agency for B2B SaaS companies. The company has an extremely decorated background when working with technology clients such as Freshworks, Intel, Appfolio and many others. They have an extremely strong background in traditional search marketing which gives them a strong leg up in generative engine optimization.

Stratabeat uses a model that blends both traditional SEO and generative engine optimization.

How To Choose A SaaS Generative Engine Optimization Agency

With GEO still in its infancy, figuring out how to vet an agency can feel a little like guessing which ChatGPT plugin will actually work. Here’s how I’d approach it.

Start With SEO Roots

There are real differences between SEO and GEO, but that doesn’t mean the old playbook is useless. Agencies with deep SEO experience are often better equipped out of the gate. That’s because GEO isn’t just about prompts—it’s content, outreach, social monitoring, technical cleanup, data infrastructure, and cross-team execution. An SEO shop that’s been around the block will already have that scaffolding in place.

Look For Real AI Visibility Tracking

This is non-negotiable. The best GEO firms have already built out tracking across ChatGPT, Perplexity, Claude, AI Overviews and more. They’ll help you monitor brand prompts, spot competitors that keep surfacing, and understand what kinds of citations and formats each engine prefers. If they can’t show you how your brand appears across LLMs, walk away.

They Need To Know The Models

Not all AI engines are built the same. Google’s AI Overviews are very different from ChatGPT-style answers—especially in how they ground information, cite sources, and index content. A good GEO agency will know the nuances between them. They should be able to break down how to optimize differently for AIOs versus Perplexity versus Claude.

GEO Requires Both Content & Technical Chops

AI engines aren’t just looking at your copy, they’re looking at site structure, crawlability, schema, and sometimes even what JS frameworks you’re using. Some engines still struggle with JavaScript. Others prioritize structured data and information density. That means a good agency will need to bring both content strategy and technical know-how to the table. If they lean too hard in one direction, that’s a problem.
