AI influencer marketing agency for tech brands on X and LinkedIn
GrowthMatrix is an AI and technology influencer marketing agency. We run creator campaigns for AI and tech brands on X and LinkedIn, occasionally adding Instagram when a launch needs consumer reach, using a network of 500+ vetted creators. Brands including Cartesia, Natura Umana, Durable, Tavus, H Company, Simular, webAI and PixVerse have launched with us.
Who we work with
- Voice AI and model labs: Cartesia, Tavus.
- AI agents: H Company (Runner H), Simular, JovidaAI.
- AI hardware: Natura Umana, Project Mirage.
- On-device and developer AI: webAI, Qodo.
- AI video and creative tools: PixVerse, ReadKidz.
- AI business tools and fintech: Durable, You.com, Taka.
We also work with SaaS, devtools, consumer apps, hardware and fintech when tech audiences would care about the launch.
Influencer marketing for AI startups
Early-stage AI startups usually have a strong product and a small audience. Creators fix the audience part. JovidaAI launched from a 73-follower account and reached 105K views with 14 creators in one day, and ReadKidz finished #3 Product of the Day on Product Hunt with creator posts and multilingual threads. A startup launch doesn't need 150 creators. It needs the right 14.
The creator network
- 500+ vetted creators across X and LinkedIn.
- Builders, founders, educators and reviewers, hand-matched to your audience and niche.
- A devtool gets developer voices. A consumer app gets creators with reach beyond the tech bubble.
- Global lineups, plus US, UK and Europe lineups.
Technology, SaaS and B2B influencer marketing
Tech buyers trust builders more than ads. For developer tools and AI agents, we put developer creators on X who show the product working, the way 30+ creators ran hands-on demos for H Company's Runner H public beta. For SaaS and B2B products, we add LinkedIn founder voices, so the launch reaches the people who sign off on budgets, not just the people who try things first. See our LinkedIn influencer marketing agency page. Read our full guide to SaaS and B2B influencer marketing.
For SaaS and B2B launches, see our SaaS and B2B influencer marketing agency page.
What we run
- Launch campaigns: a full wave timed to your release, mixing formats and platforms.
- Starter pushes: a focused first wave with a hand-picked group.
- Always-on: monthly creator waves for brands that keep shipping.
Formats: quote reposts, repost waves, threads, original posts, LinkedIn founder voices, native video and demos, Product Hunt support and waitlist sprints.
By product type: SaaS and B2B software, developer tools and APIs, AI models, AI agents and voice AI. Planning the whole launch? See our product launch agency service, or the X launch agency for X-first launches.

What clients say
"We wanted launch day to feel massive. 150+ creators hit at once and the wave ran past 5M impressions. The waitlist felt it the same day."
"We asked for a lean launch push. 14 creators, one day, 105K views. Exactly what we wanted."
"We wanted the Runner H beta in front of developers fast. The push cleared 867K views on launch day."
How we pick creators
Creators are chosen for fit with your buyer, not follower count alone: the people who build with, buy or recommend products like yours. Every creator writes in their own voice from a brief, you approve every post, and every paid post carries the platform's paid partnership label.
AI influencer agency or influencer agency for AI brands?
The words get used for two different things, so it helps to know which one you need.
- An agency for AI influencers creates or manages virtual, computer-generated influencers. The influencer itself is the AI.
- An influencer agency for AI brands works with real people (builders, founders, educators and reviewers) who post about AI products to an audience that trusts them. The product is the AI.
GrowthMatrix is the second kind. We don't create virtual influencers. We put real creators your buyers already follow behind AI and tech launches on X and LinkedIn.
How to choose an AI influencer marketing agency
Six checks before you sign:
- Public proof you can open. Ask for real launch posts with views and quotes you can check yourself, not screenshots. Every one of our case studies links to the public posts.
- Creators who understand AI. A creator who has used tools like yours explains them better than a bigger account with a general audience.
- The right platforms for your buyer. X for builders, developers and early adopters. LinkedIn for the people who sign off on budgets.
- You approve every post. Creators should write in their own words from a brief, and nothing should go live without your OK.
- Paid posts are labelled. Every paid post should carry the platform's paid partnership label.
- A clear result agreed upfront. Every GrowthMatrix X campaign has an agreed impressions floor, and if the wave falls short we add creators at no extra cost.

FAQ
What does an AI influencer marketing agency do?
It connects AI and tech products with creators their buyers already trust, plans the campaign, briefs the creators, times the posts to the launch and reports the results.
Which platforms do your AI influencer campaigns run on?
X and LinkedIn are our core platforms. We occasionally add Instagram when a campaign needs consumer reach.
Do you only run influencer marketing for AI companies?
AI and tech are our home turf. We also work with SaaS, devtools, consumer apps, hardware and fintech.
What does an AI influencer marketing campaign cost?
Every campaign is scoped to your product, goals and creator mix. Book a 30-minute call and you'll have a quote the same day.
Are you a tech influencer marketing agency?
Yes. GrowthMatrix is a technology influencer marketing agency. We run campaigns for AI and tech brands, including model labs, AI agents, devtools, SaaS, consumer AI apps and AI hardware, with a network of 500+ vetted tech creators.
Do you run B2B and SaaS influencer campaigns?
Yes. For B2B and SaaS launches we combine developer and builder creators on X with founder voices on LinkedIn, so the launch reaches both the people who try the product and the people who buy it.
Can an early-stage AI startup work with influencers?
Yes. JovidaAI launched from an account with 73 followers and reached 105K views with 14 creators in one day. A small, well-matched group usually beats a big, generic one.
What's the difference between an AI influencer agency and an influencer agency for AI companies?
An AI influencer agency creates or manages virtual, computer-generated influencers. An influencer agency for AI companies works with real creators who post about AI products. GrowthMatrix is an influencer marketing agency for AI and tech companies and works only with real creators.
How do I choose an AI influencer marketing agency?
Ask for public launch posts you can check, creators who understand AI, the right platforms for your buyer, approval on every post, paid partnership labels, and a result agreed before the campaign starts.
How long does it take to set up an AI influencer campaign?
Plan for at least three weeks before launch day. That leaves time to pick creators, brief them and approve every post. A focused starter push can move faster when the product and the launch post are ready.
