B2B cross-promotion platform for websites & SaaS
Show the ads of complementary B2B businesses on your website, and your ads appear on theirs. AI finds the right partners, your competitors are blocked automatically, and you approve every ad. No ad budget needed.
Who B2B cross-promotion is for
Any business that sells to other businesses and has a website with visitors. You exchange exposure with companies whose customers could also need you.
SaaS companies
Reach the users of tools that work alongside yours. A CRM can appear to the visitors of an invoicing app, an analytics tool to the visitors of a marketing platform.
- New sign-ups without paid ads
- Partners chosen by audience fit, not by who pays most
- Conversions tracked and counted
Business websites & B2B services
Agencies, consultancies, B2B shops and service providers can turn their website traffic into exposure on other relevant business sites.
- Your space shows only non-competing businesses
- Your ads reach decision-makers on other B2B sites
- Free plan, forever
What makes it built for B2B
Business audiences are small and specific. Showing the wrong ad to them — or a competitor's — costs more than it brings. That's why the network is built around four rules.
B2B meets B2B
B2B businesses are connected only with other B2B businesses. B2C and B2B2C have their own rules, because their visitors are different.
No competitors
Businesses that compete with you are identified and blocked before any ad is chosen. It's the network's core rule, not a setting.
AI audience match
AI compares category, subcategory and business description and gives every pair of businesses a 0–1000 score for how complementary their audiences are.
Your control
Approve every ad before it shows, allow only the categories you want and block specific businesses from your dashboard.
Start in four steps
Most of the setup is guided, and AI does the heavy lifting.
Add your business
Enter your name and website. AI reads your site and writes the business description used for matching. You can edit it.
Choose B2B
Set your type to B2B so you are matched only with other business-to-business companies.
Add the snippet
Paste a small block of code where the ads should appear. An AI assistant shows you where and checks it works.
Create your ads
Upload an image, a YouTube video or HTML5 — or let AI create the ad from your description. Then choose Auction or Balance.
Two ways to share exposure
Pick the model that fits your goal and switch anytime, at no extra cost. Competitors stay blocked in both.
Weighted Auction · default
Impressions go to businesses by weight: the AI match score plus profile points earned from the impressions and verified conversions you give. Built for conversions.
Impression Balance
Get as many impressions as you give. The platform keeps what you give and receive as even as possible, and small differences are compensated automatically.
Cross-promotion vs. paid B2B ads
Cross-promotion doesn't replace every channel, but it removes the biggest cost of early growth: paying for every click.

B2B cross-promotion: questions
What is B2B cross-promotion?
B2B cross-promotion is when two businesses that sell to other businesses, but don't compete with each other, show each other's ads to their own audiences. Each side reaches new, relevant customers without paying for ads.
Is the B2B cross-promotion platform free?
Yes. PhronexusAI has a permanent free plan with no credit card: up to 100 Auction and 100 Balance participations per day. The paid plan costs $7/month and raises the limit to 3,000 per day for each pool.
Will my competitors' ads appear on my website?
No. Before any ad is shown, the platform identifies businesses that compete with you and blocks them automatically. This is the network's core rule, not an optional setting.
Does it work for business websites that are not SaaS?
Yes. Any business with a website can join. B2B businesses are connected only with other B2B businesses, B2C with B2C, and B2B2C with both, because the visitors of each type are different.
Do I need technical skills to start?
No. You paste a small snippet into your site to open the ad space. An AI assistant shows you exactly where to place it and checks that it works. AI can also create your ads for you.
Can I control which ads appear on my site?
Yes. You can approve every ad before it shows, choose which categories are allowed and block specific businesses from your dashboard.
