The Best AEO Services for Seed-Stage B2B Startups in 2026, Scored on the Same Five Criteria
Short version. We scored ten AEO services that sell to startups on five things a founder can check on each vendor's own website in about ten minutes: is there a price, can you stop after one round, do they ship the changes themselves, do they show how they measure, and are there results you can check. Every score comes from the vendor's own pages, checked on October 5, 2026. The two highest scores went to Humans with AI and Discovered Labs, 4 out of 5 each, and they are very different purchases: one is a $149-a-month platform your marketer runs, the other a done-for-you team from about €7,000 a month that says it is built for Series A and later. We are on the list too, scored by the same rules. Our row sits at the bottom of the table, not the top, and the last section explains how to discount it.
Read this list the way Claude would tell you to
On September 28 we asked Claude and GPT-6 Sol two questions, five fresh sessions each, web search on: "What are the best answer engine optimization services for a seed-stage B2B startup that wants to show up in ChatGPT?" and "Which AEO agencies are considered the best for B2B startups right now?"
In 9 of Claude's 10 answers, the first thing it said was a warning about lists like this one. One of them, word for word: "Almost every 'best AEO agency' list you'll find is published by an AEO agency — and it ranks itself at or near the top." GPT-6 Sol never gave that warning. It built its shortlists from what vendors publish about themselves, and said so: "My shortlist is based on published scope and pricing; I haven't independently verified agency case-study results."
Checking the vendors' own sites for this post made the warning concrete. First Page Sage's article on what GEO costs lists, among the ways to get a company placed in AI answers, "publishing your own superlative list article and ranking your company first." Avenue Z runs a paid placement program on its own media site in which "Listicle placement fees are tiered by rank." Of eight agencies we checked, seven publish a "best agencies" list of their own. Six of those put themselves first, and two say so on the page. The seventh went the other way: Breadchaser ranked itself ninth of nine and wrote "We are on this list too, we wrote it."
So this post works like this. The five criteria come before any names. Every score is something the vendor's own website says, linked below. Our own row is scored by the same rules and kept out of the ranking. And the last section says which criteria favor the way we sell.
The five criteria, and why each one
Each criterion can be checked on the vendor's own site without a sales call, and each comes from what buyers ask for in public threads about hiring for this.
| # | Criterion | Full point when the vendor's own site... | What a buyer said |
|---|---|---|---|
| 1 | Price on the page | ...prints a price or a starting price for the service. A budget dropdown on a contact form does not count | GPT-6 Sol, above: shortlists are built from "published scope and pricing" |
| 2 | You can stop after one round | ...offers month-to-month, a single project or a pilot, with no minimum of three months or more | "A good chunk of this is still single-snapshot data being used to sell a 12-month contract" (r/aeo, June 2026) |
| 3 | They ship the changes | ...says the vendor writes and publishes the pages and works on the third-party sources, not only recommends | "I don't want a strategy shop that shows up with a nice deck and then disappears ... Execution, not advice." (r/b2bmarketing, April 2026) |
| 4 | The method is shown | ...says how many times each question is run and on which engines, or publishes a sample report | "Ask them to show you a real baseline report from a client (redacted is fine)." (r/SaaS, August 2026) |
| 5 | Results you can check | ...publishes a client's before and after together with the questions it was measured on, and promises no ranking or position | "Show me a client's LLM citation share before and after, with the prompt set you tracked. If they can't produce it, they're guessing." (r/SaaS, May 2026) |
Half points: a price only for a partial offer (1); month-to-month that requires a paid upfront project first, or a site that says most clients sign for 6 to 12 months (2); a vendor that drafts but leaves writing or publishing to your team, or whose pages contradict each other (3); engines and tools named but not how many runs (4); a named client's before and after without the questions, or results on the vendor's own domain only (5). A promised ranking or position sets criterion 5 to zero. "We'd tell you on a call" counts as nothing here, because the point of the list is what you can know before the call.

The ten, one at a time
Humans with AI · 4
A platform with human support, not a done-for-you agency, and its own pricing page says so plainly. Asked who runs the platform, it answers: "You do. Your marketer sets the prompt map, approves briefs and publishes; the Workspace agents do the work. Our team is human support on every plan ... but we do not write for you. If you want us to run it, that is a Custom conversation." Plans run from $149 a month (100 prompts scanned in ChatGPT once a month, one article) to $4,997, month to month. Apart from us, it is the only vendor here that states how many times each question runs: "A scan runs every prompt on your plan through every engine on your plan once."
Its Birdview case names the client, gives the result (0.9% to 21.5% ChatGPT visibility in eight weeks) and says what did not work: "360 of 589 prompts still never cite the site." The question set itself is not published. One line to read carefully: the pricing page headline says "Two months to result, not twelve like SEO," while its terms say no platform can guarantee a citation outcome. Pricing · Birdview case
Choose it if someone on your team will run a tool and publish what it drafts, and you want to start for less than $200 a month.
Discovered Labs · 4
A full-service team: "Our default way of operating is to handle end-to-end strategy and implementation." Prices are on the page in euros: Establish is €7,995 a month month-to-month, €6,995 on a six-month commitment, and a one-off diagnostic costs €4,370, credited to the first month if you sign within 14 days. "Every retainer is month-to-month by default, with 30 days notice to cancel." Its tracker page has the most careful statistics on this list (every number carries a credible interval, and a move only counts if it holds across three runs), though it does not say how many times each question is sampled.
The incident.io case names the client and the move, "AI visibility climbed from 38% to 64%," without the questions. It says outright: "nobody can honestly promise a fixed ranking or citation." It also says who it is for: "the fastest-growing Series A+ SaaS companies." Pricing · Method
Choose it if you are Series A or later, have the budget, and want a team to do all of it.
RevenueZen · 3.5
Done for you, with digital PR, roundup placements and schema in the scope. Prices are on the page, but read the tiers: the $3,000-a-month Foundation tier is "AI brand monitoring + monthly written report," and the full GEO program starts at the $10,000 Scale tier. "No, we don't require a long-term commitment." It names the engines it tracks but not how many runs, and its headline result ("358% Increase in total AI overviews") does not name the client. Its MSA guarantees no results. One honest line from its own startup page: "For most Series A startups, starting with something like Otterly.AI or Peec AI…" Pricing · GEO service
Choose it if you want PR-led placement and can spend at the Scale tier; below it, you are buying monitoring and a report.
Omniscient Digital · 3
Done for you, from "Full-service engagements start at $10,000 a month," with no month-to-month option on the page: "we generally recommend planning in quarters." Its Convert case is one of the better ones published: "grew Convert's LLM prompt visibility from 31% to 55%" with example questions, though not the full set. It is explicit about guarantees ("Anyone guaranteeing instant rankings or predictable AI recommendations is promising more certainty than these channels allow") and about fit: "Very early-stage companies without clear product-market fit" have other problems to solve first. Its own agency lists put itself first, with a disclosure line saying so. FAQ · Convert case
Choose it if you have product-market fit, a quarterly budget, and want a content-led program.
Optimist · 2.5
Priced on its homepage: a $7,500 one-time Roadmap, Advisory from $3,000 a month, Full Service from $4,000. The pages disagree about who does the work. The homepage offers full-service execution; the About page says "We don't take the keyboard" and "For done-for-you execution, we refer clients to our trusted partners." Month-to-month is "Available only after a CORE Roadmap." Its AEO results are anonymous and measured in revenue, not visibility. It says who it is for: "Optimist works best with B2B tech and SaaS companies on the Series A to IPO arc." Home · About
Choose it if you want senior strategy and have a team to execute it.
GrowPad · 2.5
"Best for: Seed to Series B SaaS companies," with pricing that "starts from $2,000 per month," the lowest monthly retainer among the agencies here. Its terms allow cancelling on 30 days' notice, but its startup page says "Series A+ startups typically commit to 6–12-month retainers." It does some of the writing and coaches your team on the rest. Its travel-software case tracks 55 prompts and reports visibility moving from 9 to 49 of them. It loses criterion 5 on one line: its site promises "Top 1–2 AI positions" in priority prompts, while its terms say it does not guarantee rankings. Case studies · Service
Choose it if you are seed-stage, want a lower monthly price than the others, and have someone who can write.
Avenue Z · 2
A PR-heavy agency that does the work, "We manage placements end-to-end," and has a named framework (AIVx and a Z-Score). There is no price on the AEO pages and no stated contract length. Its Prometeo case names the client and a baseline ("Baseline AI visibility averaged 7%") but not the questions. Worth knowing when you read rankings in this category: its paid placement program sells listicle slots on its own media site, with fees "tiered by rank," and at least four of its own agency lists rank Avenue Z first. AEO for B2B tech · Paid placement program
Choose it if your buyers read the trade press and you want PR to carry the work.
GTM 8020 · 2
Not an agency in the usual sense: it "hand-matches you with a vetted, senior operator on a fractional basis," and that person does the work, with "no long-term lock-ins" and a trial period. There is no price on the site (the booking form's lowest budget option is $3,000 to $5,000), no description of how visibility is measured, and results are given as typical multiples rather than named before-and-afters. SEO and GEO
Choose it if you would rather hire one senior person part-time than an agency.
Demand Curve · 2
Known to many founders from its growth training. Its AI search service is done for you: "We build and manage your presence across the reviews, communities, publications, and profiles that shape the answer." "We work month to month," and it serves "B2B & B2C, seed to scale." There is no price for this service on the site, the method is one sentence ("We run structured testing across the major models"), and the results are an unlabeled chart of anonymous clients. AI Search
Choose it if you already trust Demand Curve and want one team across paid and organic.
ClawWorld (us) · 4.5, not ranked
We sell a pilot sprint "from $500" a round with no monthly retainer, scope in writing before it starts. We ship the on-site and third-party work ourselves and the client approves everything published under its name. Our method page says each question runs five times per engine, alongside four control brands we do no work for, and a full redacted baseline report is public. On criterion 5 we get a half point, for the reason in the next section. Pricing · Methodology · Sample report
Our row, and how to discount it
We wrote the criteria, and two of them reward how we sell. A printed starting price and a way out after one round are exactly how ClawWorld is packaged. We think a seed-stage buyer should weigh them, because a team with eighteen months of runway cannot sign a twelve-month retainer to find out whether the work moves anything. But a vendor that sells differently would have picked different criteria.
The criterion that matters most is the one we are weakest on. We have no client before-and-after to publish yet. Our only public results are on our own domain at /lab, and on category questions they are still zero: from September 11 to 19 we asked the OpenAI stack nine questions a buyer of this service asks, three fresh sessions each, every night: 243 answers, and ClawWorld was named in none. We publish that because a vendor who hides its own zero would hide yours.
Take our row out and the list is: Humans with AI and Discovered Labs (4), RevenueZen (3.5), Omniscient (3). Read columns, not totals: if nobody on your team will write or publish, sort by criterion 3 and ignore everything that scores under 1 there. If you can only commit a month at a time, sort by criterion 2.
Three we read and left out
- First Page Sage says "the majority of our clients are midsized companies," and the price ranges in its cost guide are what it has seen in the market, not its own prices. Its article on GEO costs is where the "ranking your company first" tactic above comes from.
- Minuttia describes itself as relevant for "B2B SaaS SEO (mid-market and above)" and for companies that "have product-market fit," with a typical minimum engagement of $5,000.
- Breadchaser is "built for brick-and-mortar health, fitness, and wellness" and quotes B2B work separately, so it does not fit this list. It deserves a mention anyway: it publishes the most complete method we found (logged-out checks, five engines, weekly), publishes results where it scored zero, and ranked itself last on its own list.
Profound and Peec are not here because they are software, not services. If you are choosing between a tool and a service, that comparison is its own post: Profound vs Peec vs Humans with AI vs ClawWorld.
How we checked
Only each vendor's own public pages, on October 5, 2026: pricing, service, terms, case study and about pages, rendered in a browser where prices load by script, with copies kept. Nothing from third-party roundups, including ours. That rule matters more than it sounds: while checking we found one vendor's roundup misquoting two competitors, and another vendor's page written for AI assistants still quoting a competitor's tiers that the competitor's own pricing page no longer lists. We will re-check every row each quarter. If we got something about your company wrong, write to hello@claw-world.app and we will fix it with a dated note.
Disclosure
ClawWorld is an AEO (Answer Engine Optimization) service for B2B startups based in New York, and it competes with every service on this list. No company on the list was contacted about this post or paid to appear in it.
