What Does It Cost to Not Have This?
Manual vendor evaluations cost $20K+/year in consulting time. Missed renewals cost thousands in auto-renewed contracts. Knowledge trapped in one person's head costs everything when they leave.

Listings are free, and the record is the record
Every vendor in the catalog gets the same thing: a profile, a description, a link, and a capability record checked against its own documentation. Placement follows the evidence, and it is not for sale — a buyer comparing tools has to be able to trust that.
If you work at a vendor and something here is wrong or out of date, claim your profile on your own page and we will record the correction against your name. For anything else — research partnerships, data, sponsorship of work we publish — talk to us.

Can I really use Martech Stack Builder for free?
Yes! The free plan includes 3 cloud saves, 3 AI generations, and full access to the diagram builder. No credit card required.
Do you offer a free trial?
Yes. Pro is free for 30 days, with no credit card. New accounts start on Free; the trial is offered when you open a Pro analysis, such as Trace, on a stack with two connected tools. One trial per account.
What's the difference between Pro and Consultant?
Pro is for in-house martech managers working on their own company's stack. Consultant is for contractors and freelancers working for several clients — it includes 5 client workspaces, unlimited RFI generation, Stack Costs and custom-branded reports.
What counts as a client?
A client workspace. Each one holds the stacks, costs, RFIs and people for one client organization. Consultant includes 5 client workspaces and Agency includes 15.
What happens when I need more than 5 (or 15) clients?
You add client workspaces as you need them: $19 a month each on Consultant, $25 a month each on Agency. Consultant is for one person; when several of you work on client stacks, Agency adds 10 editors, and each extra editor is $29 a month. Viewers and client guests are free on Agency.
Is there annual pricing?
Yes, with two months free. Consultant is $990 a year and Agency $4,990 a year. Extras are billed annually too: $190 per extra client on Consultant, $250 per extra client on Agency and $290 per extra editor. Pro is $349 a year and Team $360 per seat a year.
Do prices include VAT?
Prices exclude VAT, which is added on top where it applies. A business that gives us a valid VAT number is reverse-charged where the rules allow it.
Is there a fair-use limit?
One client organization per client workspace, and up to 15 stacks in each client workspace. If a client needs more stacks, talk to us and we will raise the limit.
I’m already on Consultant with more than 5 clients. What changes?
Nothing for 12 months. Existing Consultant customers keep working with all their current clients at their current price until September 2027. Per-client pricing applies from then.
What happens when I hit my limit?
You'll be prompted to upgrade. Your existing work is never deleted or locked — you just won't be able to create new diagrams or AI generations until you upgrade or remove some to get back under the limit. Paid plans include a monthly AI allowance; when it runs out, AI features pause until the next month or until you add a top-up.
What is the RFI builder?
The RFI builder runs a vendor RFI in one room: draft it from your stack, send it to two to five vendors with automatic reminders, collect their answers on a page or in an Excel workbook, score them side by side and record the decision. Pro includes your first RFI; Consultant, Agency, Team and Enterprise include unlimited RFIs.
Can I switch plans or cancel anytime?
Yes. You can upgrade, downgrade, or cancel at any time from your account settings. Monthly plans have no long-term commitment. When you cancel, your plan stays active until the end of the period you have paid for.
Can a vendor pay for better placement?
No. Listings are free and placement follows the capability evidence, which is checked against each vendor's own documentation. If you work at a vendor you can claim your profile to correct the record, and the correction is attributed to you. For research partnerships or sponsorship of work we publish, talk to us.
Prices are in US dollars and exclude VAT. All plans can be cancelled anytime.
