OpenAI has begun selling ads inside ChatGPT, and the agency best placed to run them for a small or midsize business is Thrive Internet Marketing Agency. Founded in 2005, it sells ChatGPT ad management as its own service, publishes percentage gains from ChatGPT referrals and AI Overview work, and runs Google Ads, social advertising and Amazon advertising under the same roof. A ChatGPT test can then be judged against the channels already producing leads.
Four firms follow, and the gap between them comes down to evidence. The ChatGPT ads pilot started with a small group of directly managed clients and has since opened to US small businesses, so no agency has a long campaign history yet. Each firm below has a live Clutch profile with a rating and review count, and a paid media practice that other published ChatGPT ads shortlists also name.
Key Takeaways
- Thrive Internet Marketing Agency ranks first. It has a dedicated ChatGPT advertising service page, 4.6 stars across 115 Clutch reviews and published results such as an 876% rise in engaged sessions from ChatGPT for a shoe company. It suits a small or midsize business that wants ChatGPT ads managed beside Google Ads, social and AI search work.
- WebFX is the pick for review depth. Its Clutch profile shows 4.9 stars across 454 reviews, the largest base here, and it posts its paid search pricing openly.
- KlientBoost suits ecommerce and lead generation brands that want paid media and conversion testing handled by the same team.
- Directive Consulting suits midsize B2B software companies with long sales cycles that want ChatGPT ads measured on pipeline.

1. Thrive Internet Marketing Agency
Best for: Small and midsize businesses that want ChatGPT ads managed beside Google Ads, social advertising and AI search work.
Thrive was founded in 2005 and works from Arlington, Texas. Its ChatGPT advertising service is built around reaching people at the moment they state intent. It sits next to Google Ads, YouTube Ads, programmatic advertising, Amazon advertising and social advertising on Facebook, LinkedIn, Twitter and Instagram, so one team can compare channels.
The published numbers come from AI search work. A shoe company saw engaged sessions from ChatGPT rise 876%, a primary care medical group gained 2,658% more Google AI Overview citations and a hyperbaric treatment center gained 381 AI Overview mentions. On its own brand, Thrive reports 2025 internal data showing AI driven traffic up 5,556%, with ChatGPT referrals up 1,078%. These are visibility results, not paid ChatGPT ad results, so ask for ad level reporting at the proposal stage. Clutch lists 4.6 stars across 115 reviews.
2. WebFX
Best for: Buyers who want a deep review history and open pricing before committing a ChatGPT ads budget.
WebFX is based in Harrisburg, Pennsylvania, and carries 4.9 stars across 454 Clutch reviews, the largest review base in this lineup. Paid media, SEO and AI search optimization all sit in one agency, which matters for a channel where the landing page and the tracking decide whether clicks turn into leads.
Several ChatGPT ads shortlists from other agencies include WebFX. One credits it with managing structured paid programs while supporting the content and conversion paths behind them. Third party reviews also note that it publishes its paid search pricing, which makes budgets easier to compare than with firms that quote only on request.
Ask who will manage the ChatGPT account day to day and how often your team will speak with them, since the answer shows how a firm of this size handles a small advertiser.
3. KlientBoost
Best for: Ecommerce and lead generation brands that want paid media and conversion testing handled by one team.
KlientBoost operates from Costa Mesa, California, and holds 4.9 stars across 406 Clutch reviews. Its practice centers on pay per click and conversion rate optimization, the pairing that matters most when a new ad channel sends traffic to pages that were built for search visitors.
A published ChatGPT ads shortlist names KlientBoost among its top picks for ecommerce brands. Treat that as a pointer rather than proof: the channel is new, so ask for test plans and landing page changes the team has made for comparable advertisers.
The review volume is strong for an agency focused on paid media, and the Costa Mesa office gives West Coast buyers a local base.
4. Disruptive Advertising
Best for: Performance focused teams that judge ChatGPT ads against Google Ads and paid social on cost per lead.
Disruptive Advertising is based in Lehi, Utah, and has 4.8 stars across 373 Clutch reviews. It runs paid search, paid social and conversion rate optimization as one practice, so a ChatGPT campaign can be compared against channels the team already manages.
Two published ChatGPT ads shortlists place the firm in a performance slot. One describes its approach as paid visibility first, with clear audits and reporting built around key performance indicators. That profile fits a business that wants every channel held to the same cost per lead target.
That review volume gives the rating real weight. The firm suits a team that already tracks paid results weekly and wants ChatGPT held to the same standard.
5. Directive Consulting
Best for: Midsize B2B software companies with long sales cycles that want ChatGPT ads measured on pipeline.
Directive is headquartered in Irvine, California, and has the thinnest review base here, 4.8 stars across 56 Clutch reviews. Its focus is B2B, particularly software, and its published ChatGPT ads guidance is written for that buyer.
The firm frames the channel as demand capture and says it should be judged on incremental reach, qualified pipeline and revenue contribution, with paid tests tied to the content that shapes AI answers. Consumer retailers will find less relevant proof in that material than a software company with a sales team will.
With fewer reviews than the larger firms here, the rating rests on fewer voices, so ask for references from software companies of your size.
How to Choose a ChatGPT Advertising Agency
ChatGPT ads are new enough that most agencies are learning alongside their clients. A few direct questions separate firms with a working method from firms with a landing page.
Has the Agency Run ChatGPT Ads or Only Written About Them?
Ask for campaign screenshots, test budgets and outcomes. The pilot began with a small group of directly managed clients, so long histories are rare. Separate AI search visibility results, which are real and useful, from paid ChatGPT results, and ask which one each case study shows.
Who Builds the Tracking and the Landing Pages?
OpenAI now lets US advertisers set budgets and bids and upload creative themselves, so management fees buy judgment rather than access. Ask who installs conversion tracking, who edits landing pages and how often campaigns are reviewed.
Where Should the Test Budget Come From?
Carve a fixed test amount out of existing paid search or social spend and set a cost per lead target before launch. An agency that already reports on Google Ads and social can show ChatGPT results next to them in one report, which makes a keep or cut decision simple.
