The Best Marketing Agencies for AI Startups After a Funding Round

Team 4 is a London B2B SaaS marketing agency, and it says it works with AI software companies. It runs SEO, GEO (visibility in AI search), content, PPC and paid media, and Webflow sites as one program under its Inbound Engine® method, aimed at pipeline from organic search and AI answers that keeps growing without constant ad spend.

Its website names Great Wave AI among its clients, alongside Adversify, Atomic Jolt and AirDNA, and lists a case study on data-driven web design for Forecast AI. Its services include AI search visibility and LLM optimization, demand generation and performance marketing. Our profile describes a consultancy-first start that maps the whole acquisition setup before any work is built, beginning at the bottom of the funnel. It was a European Search Awards finalist in 2025 and 2026.

Team 4 says it has worked with SaaS companies at every funding stage, from seed to Series C and later, which fits an AI company scaling after a raise. It suits best where the ICP is clear and the aim is inbound that carries more of the pipeline target. Our profile says it suits less well companies without a clear ICP yet, or those after high-volume content with no strategy behind it.

SimpleTiger is a Sarasota agency that has worked only with B2B SaaS for more than 15 years, and its website calls it a B2B SaaS marketing agency and AI search leader. It covers SEO and AEO, GEO (AI search), paid search and social, content, link building, digital PR and Webflow design, so an AI company can run inbound and paid with one team.

Its site lists AI Companies and Automation & AI among the industries it serves, next to martech, cybersecurity and analytics platforms. Clients named on its site include Firecrawl, Gainsight, Jotform, Invoca and Segment. SaaS Hackers has no AI case study on record for it, so the AI evidence is that industry list. Our profile cites its Gelato case study, a 1200% increase in first-page keyword rankings in 12 months at a 3:1 ROI in year one.

SimpleTiger suits funded AI software companies that want organic search, AI search and paid run by one SaaS-only specialist, with a Webflow site built for search. Companies that want proof of AI work should ask for named AI examples before signing.

Named clients include Ideagen, Epicor, Ravelin and Crownpeak, and SaaS Hackers has no named AI client or case study on record for it. Our profile cites case studies reporting £2.1m in pipeline from demand generation, and a pricing page with packages, so a buyer can see costs before a first call. The directory lists scale-ups as its focus.

Gripped suits funded AI companies on HubSpot that want inbound, paid and attribution run as one program with clear reporting. A company that wants proof of AI work should ask for named AI examples, and one that isn't on HubSpot should check how much of the offer it would use.

Its services include SaaS, technical and programmatic SEO, content strategy and production, link and citation building, and named services for ChatGPT SEO and Claude SEO.

Its website lists AI SaaS among more than twenty software sectors it works in, with DevTools SaaS and BI & Analytics SaaS.

TripleDart suits funded AI startups that want paid, organic and ABM running together, with quick wins early and a longer roadmap behind them. A company that wants named AI case studies before it signs should ask for them on the first call.

The directory lists start-ups as its focus.

Hey Digital suits a funded AI SaaS company where paid is the growth lever to scale, especially for trial sign-ups and demos. Companies that want SEO, content or AI search visibility will need another partner, since its services stay with paid media, creative and landing pages.

NoGood suits funded AI companies, including ones that sell to consumers, that want rapid paid, creative and social testing to find what grows. A B2B AI company with a long, sales-led cycle should ask for B2B examples, since its industries also include consumer and ecommerce brands.

Obility is a Portland performance marketing agency for SaaS and B2B tech companies. It runs paid search, paid social, SEO, GEO, Reddit and content creation, and connects campaigns to CRM and sales systems so revenue can be traced back to each channel.

Its website lists AI & Machine Learning and Artificial Intelligence among the industries it serves, with DevOps, cybersecurity and martech. Named clients include Snowflake, Fastly, Hitachi Vantara and Autodesk, and our records don't describe any of them as an AI client.
