Best B2B Marketing Tools & Resource Recommendations

Below is a list of B2B marketing tools I use regularly. Some are free, some are paid. I try to keep this list current — if something falls off, it means I stopped using it.

If you buy anything through a link on this page, thank you — genuinely. And if you have questions about any of these tools or want a recommendation for your situation, reach out here or find me on LinkedIn. Happy to help.

Marketing Foundation Check — A free 10-question self-assessment that shows you where your marketing foundation is solid and where you have gaps. Covers your numbers (CAC, LTV, close rate), your buyer, your offer, and what's actually generating revenue. Takes 3 minutes. Worth doing before you spend another dollar on ads or tools. Take the Free Check.

Unit Economics Calculator — Most business owners I talk to don't actually know their numbers. Not because they're bad at business — they've just never had a reason to lay it all out. But if you don't know your CAC, LTV, close rate, and profit per customer, you're guessing. And guessing is expensive. This calculator puts it all in one place so you can see exactly what a new customer is worth — and whether Google Ads, LinkedIn ads, a marketing agency, and any other marketing spend is actually going to pay off before you commit. Bonus: if you're planning to use AI in your marketing, knowing these numbers means you can get far better results from AI — you can tell it exactly what you're working with and what winning looks like. Clean inputs, better outputs. Run the Numbers.

The Small Budget Manufacturer's Google Ads Blueprint — If you're running Google Ads on a $1K–$15K/month budget and wondering why the results don't match the spend, this is for you. Pull the framework that actually works at your budget. Get the Free Blueprint.
