What entity work means for a B2B SaaS
An entity is a thing a search engine can identify and describe, such as your company. Google's Knowledge Graph "has millions of entries that describe real-world entities like people, places, and things." A Knowledge Panel is the box Google shows for an entity that is in that graph. The two are different things. A company can sit in the graph without a claimed panel.
You cannot buy a panel. Google's help page says "Not all knowledge panels are claimable as of now", and claiming one means signing in to an official profile you control. An agency can prepare the entity and the route to verification. It cannot promise the outcome.
Three pieces of entity work do most of the job.
- Organization markup with identity pointers. Google says organization markup helps it "disambiguate your organization in search results." The schema.org property sameAs is defined as a "URL of a reference Web page that unambiguously indicates the item's identity." Google also says no property is required, so a vendor who "adds schema" has met no bar.
- A Wikidata item. Wikidata accepts an item that meets one of three notability criteria, and criterion 2 reads "It refers to an instance of a clearly identifiable conceptual or material entity that can be described using serious and publicly available references." A Wikipedia article is one route to an item, and an item can exist without one.
- Consistent facts on pages engines read. Our own study of 2,895 tracked AI answers found that 624 of the 631 times an engine named LoudFace, it had read a loudface.co page. The full study covers the method.
For AI Overviews and AI Mode, Google says "There's also no special schema.org structured data that you need to add." Entity clarity helps an engine name you correctly, and a citation still has to be earned on top of it. Semrush found that 61.7% of 3,981 domain appearances across 115 prompts in 14 countries were citations that never named the brand. Being used as a source and being named are different outcomes, so ask any agency which one it measures. If you want the do-it-yourself version first, start with our entity disambiguation guide.
1. LoudFace
Best for: B2B SaaS teams that want entity work inside one organic growth program, with SEO, AEO and GEO, content and Webflow under one retainer.
LoudFace's GEO program covers the entity layer directly. Its page says "We map your brand to knowledge-graph entities and mark up every liftable unit." The entity sentence on your site gets fixed in week one, and the work then runs alongside shipping pages instead of ahead of them.
The answer-share figures, each with its label:
- Our own site. The share of non-branded AI answers naming LoudFace went from 0.13% in April 2026 (3 of 2,306 answers) to 21.5% across 18 to 28 September 2026 (992 of 4,624), measured in Peec across three engines. Rank among 53 tracked brands went from 40th to 3rd. September ran on a smaller prompt panel. The full write-up shows the method.
- Toku. In a 30-day Peec reading to 19 August 2026, Toku appeared in 97.8% of AI answers to the prompt "best stablecoin payroll providers". The Toku case study has the detail.
Both are answer-share readings, not entity-only results. The price: GEO programs start from $5,000 per month on a three-month initial engagement, with no setup fee.
Not the fit if: you want a one-month entity project. Programs start with a three-month engagement.
2. Exalt Growth
Best for: SaaS companies from Seed to Series C, roughly 20 to 300 people, that want an entity-first SEO system.
Exalt's page describes systems that control how your SaaS "is understood, retrieved, and recommended across search engines and AI platforms." Its EGOS methodology is the named framework, and the offer lists structured data deployment and knowledge graph optimization, plus content architecture designed for machine comprehension. The agency works from Sydney, San Francisco and remotely.
Named SaaS clients on the page are Dovetail (organic traffic up 878%) and Cascade (monthly organic traffic up 670%). Both are traffic results. Neither is an entity or AI-answer result. No price appears on the page checked.
Not the fit if: you want a measured answer-share outcome or a published price.
3. DerivateX
Best for: SaaS companies between $5M and $50M ARR that want a named entity optimization service and a price list.
The agency defines the work this way: "Entity optimization is the work of making your brand unambiguously recognisable to AI systems with the right product category, the right ICP, the right use cases, with consistent signals across every source LLMs read." The page carries a Gumlet case study headed "Gumlet turned ChatGPT mentions into 20% of inbound revenue" and a before-and-after example of how ChatGPT described Gumlet. The team operates from Bengaluru on hours that overlap US time zones.
Pricing is public. Rank & Get Found is $5,000 a month, Own Your Category is $8,000, and Market Leader is $12,000 (six-month minimum). A one-time diagnostic costs $3,500. The off-site citation budget is separate, for example $1,000 to $1,200 a month on the entry plan.
Not the fit if: you are under about $5M ARR, or you sell to consumers or local customers.
4. NYFTY Labs
Best for: teams that want Wikidata and structured data handled by the book.
NYFTY Labs (Phoenix, AZ) runs as a full-service agency, and its entity page makes a precise offer: it "makes your brand a defined, machine-readable entity across Wikidata, the Google Knowledge Graph, and your own structured data." The method is Organization and Person JSON-LD with a stable @id as the canonical node, plus a Wikidata item created under the platform's conflict-of-interest disclosure rules. That last detail is what a careful buyer should want.
The evidence is the weak point. The page says "Examples are anonymized to honor client NDAs", so you cannot check a SaaS result. No price is stated, and the page offers a free quote.
Not the fit if: you need named, checkable SaaS client results.
5. MADX Digital
Best for: SaaS teams that want entity-to-graph work inside a broader SaaS SEO retainer.
A knowledge-graph guide on the MADX site ends with an offer: "that's part of what our SaaS SEO agency builds for B2B SaaS brands." Knowledge-graph work is not listed as a named service, so ask what is in scope. The site's case study headline reads "How MoonPay Grew Organic Traffic 175% to 433,317 Monthly Visitors", which is a traffic result. The site states "50+ SaaS brands trust MADX Digital".
Pricing is public, with two terms. On a 12-month term, Authority is $3,500 a month, Growth $5,500 and Scale $9,500, which the page says saves 30% against rolling monthly. The rolling contract has a 3-month minimum, at $5,000, $8,000 and $13,500 a month.
Not the fit if: you want entity work as the headline service, or you cannot commit to at least three months.
6. Optimist
Best for: B2B teams that want entity optimization as one line inside a wider SEO and AEO engagement.
An AI search discovery offer at Optimist includes "Schema markup and entity optimization". The agency names SaaS clients with results: Glide ("14X Leads") and Stampli ("5X Inbound Pipeline"). These are SEO results. Pricing is clear: "one-time strategy and roadmap engagements from $7,500, ongoing AEO/SEO advisory retainers from $3,000/month for teams that execute in-house, and full-service engagements from $4,000/month". The page adds "All retainers are month-to-month."
Not the fit if: you want entity and knowledge-graph work as the main deliverable.
7. AEO Engine
Best for: buyers who want Wikipedia, Wikidata and Knowledge Panel presence work.
Entity work is a named service at AEO Engine, whose page lists "Presence development on entity-defining sources: Wikipedia, Wikidata, Crunchbase, industry directories, and authoritative databases." It also lists a Knowledge Panel Development line. Google says not every panel is claimable.
The named result comes from law: My Rights Law (up 315.7% in organic traffic, 673 AI citations). A second block reads "Achieved Knowledge Panel" with no client named, beside a testimonial from Dominate Dental. No SaaS entity result appears. The pricing page lists Growth at $1,597 a month and Scale at $2,997 a month, both month to month, and Enterprise from $10,000 a month, scoped on a strategy call. Entity work is named only in the Enterprise plan.
Not the fit if: you want entity proof from B2B SaaS.
8. EWR Digital
Best for: industrial, energy and professional-services B2B companies.
In Houston, Texas, EWR Digital puts its position bluntly: "Entity SEO is the foundation of modern search." The service covers schema, entity graph work and citations. The page names no clients. Its discovery-call page says most engagements range from $50K to $250K+ over 3 to 6 months, and fit is set on a call before any quote.
Not the fit if: you are a SaaS company that wants SaaS-specific proof.
9. iPullRank
Best for: enterprise sites buying relevance engineering.
iPullRank's services page frames the offer as "Relevance Engineering is a strategic approach to Organic Search that integrates the disciplines of AI, Information Retrieval, Content Strategy, Digital PR, and User Experience." That page does not use the words entity or knowledge graph. The firm does publish entity research, and one article argues that AI engines "assemble answers that are grounded in entities." That is a vendor's view from a firm that sells the service, so weigh it as opinion. Its stage pages, linked from the services page, show budget bands of $30K to $150K, $150K to $500K and $500K+ without saying what period they cover. The Growth stage names a mid-market SaaS company as one fit, but the enterprise client names on the homepage are not SaaS evidence.
Not the fit if: you want entity work sold as its own scoped service, or a stated monthly price.
10. Omniscient Digital
Best for: B2B software teams that want GEO plus SEO strategy and can pay a high price.
Generative Engine Optimization is sold at Omniscient under the line "Appear in AI search and LLM outputs". It names no entity or knowledge-graph service on the page checked. Pricing is public: "Full-service engagements start at $10,000 a month." and "The SEO & content strategy development package starts at $15,000." The page states "GatherContent grew organic sessions 867%", which is an SEO result. The agency has offices in Austin and New York, with others in San Francisco, Chicago and Boston. Among the six agencies here that publish a monthly price, its $10,000 floor is the highest starting point. See our Omniscient alternatives if the price is the issue.
Not the fit if: you want entity work as a standalone project.
Eight questions to ask before you hire an entity agency
- How will you handle Wikidata? A credible answer names the references that support the item and who discloses the conflict of interest. NYFTY states this practice on its page.
- What does your Organization markup contain? Ask for a stable @id, with sameAs pointing at reference pages. A block that holds only a name and a logo leaves the entity undefined.
- What do you promise from markup? Google says no special schema is needed for AI Overviews. A guarantee of AI answers from markup alone is overselling.
- Which named B2B SaaS client can I check? Ask for the client and the metric, then the time window and what the client received. Entity vendors often show anonymized, non-SaaS or traffic-only results.
- Do you measure per engine, before and after? Cited and named are different outcomes, and engines behave differently. Ask for the baseline and a per-engine read. Our guide to verifying agency results has the full test.
- What does it cost, and for how long? Six of the ten agencies here publish a monthly price, and two more publish budget ranges. Compare stated minimums and terms, and read our AEO agency pricing breakdown for what each band buys.
- Which stage of company do you work with? Exalt states Seed to Series C and DerivateX states $5M to $50M ARR. Ask whether the agency turns away clients outside its range.
- Where will outside references come from? Google says Knowledge Panel information comes from several places, including data partners. Entity work that stops at your own site leaves that gap open. Our guide to getting into best-of lists covers the outside half.
When not to hire an entity specialist
Run one check first. Search your company name in ChatGPT, Perplexity and Google, and ask each engine what you do. If every engine describes you correctly and the problem is that you are never named for category questions, entity work is not your bottleneck. You need pages and outside placements that answer the category question. Our best AEO and GEO agencies for B2B SaaS list and best B2B SaaS SEO agencies list cover that route.
If an engine confuses you with a company that has a similar name, or describes your product category wrongly, entity work is the right first spend.
