The KMT Stack vs HubSpot.
HubSpot is a strong platform that your team sets up and runs, often with an administrator or an agency. With the KMT Stack there is nobody else to hire: your marketer runs it with Grep, for one flat price.

Which one fits
Choose the one built for the team you have.
The KMT Stack is the better fit if
- You have one marketer or a small team, and no budget for an administrator or an agency.
- You want to see the whole funnel in one place, from a first website visit to a closed deal.
- You want the bill to stay the same as your list and your team grow.
- You want your data on its own instance in Europe, never used to train AI.
HubSpot is the better fit if
- You only need email and a basic CRM. HubSpot’s Starter plans cost far less than either platform at the level compared here.
- You want social media scheduling and SEO tools built into the same product.
- You rely on a long list of ready-made integrations from an app marketplace.
Who you need to hire
The cost that is not on the pricing page.
HubSpot gives you the software. Setting it up and getting value from it is your team’s job, which is why so many HubSpot customers add a platform administrator, or pay a HubSpot partner every month, on top of the subscription.
The KMT Stack was built to remove that cost. The setup is part of the product and the launch. Grep answers your marketer’s how-do-I questions on the screen they are on and drafts the work when they ask. For the first 90 days, a senior marketing technologist works alongside them. After that, your marketer runs it, with nobody else to hire.
What that help costs elsewhere
- $60,000 to $115,000
a year, the salary range in US job postings for HubSpot administrators (October 2026) - From about $1,500
a month, a typical HubSpot partner retainer for a small business - Included
with the KMT Stack: the setup, Grep, and 90 days alongside a senior marketing technologist
Year by year
A 10-person company with one marketer.
What you pay each year, with the one-time setup in year one, before any administrator or agency. The KMT Stack costs about $3,000 less in the first year and about $8,500 less every year after that.

One marketer, four people in the CRM and 10,000 contacts, held flat. HubSpot: Marketing Hub Professional and Sales Hub Professional on annual billing, with their required onboarding ($4,500). KMT Stack: the $5,000 launch, three months of guided operation ($6,000) and $950 a month. If your list grows, HubSpot’s bill grows with it and the KMT Stack’s does not; try your own team and list on the pricing page. AI usage beyond each plan’s allowance is not included. Prices as of 17 October 2026.
We know HubSpot
We have built marketing on it ourselves.
Before the KMT Stack, KMT set up marketing platforms for other companies, HubSpot among them, including a full rebuild for a $20 million education technology company. Read how that went. HubSpot is a good product. The KMT Stack exists for the companies that cannot staff it.
Questions owners ask
What is the KMT Stack?
The KMT Stack, from Keystone Marketing Technology, is one connected marketing and sales system (web analytics, marketing automation and CRM) with Grep, an AI assistant that amplifies your marketing and sales teams, for one flat monthly price. Your team signs into one place. KMT sets it up with you, and your marketer runs it with Grep, with a senior marketing technologist alongside for the first 90 days. See the KMT Stack.
Do we need to hire a specialist to run the KMT Stack?
No. The KMT Stack is software your team signs into and uses. Your marketer runs it with Grep, which drafts the work and answers how-do-I questions, and for the first 90 days a senior marketing technologist works alongside them. There is no administrator, agency or IT person to add.
Is HubSpot cheaper?
No. For what the KMT Stack includes, a CRM, marketing automation, website analytics and an AI assistant for your whole team, HubSpot costs about $1,660 a month for a 10-person company with one marketer, against $950 a month for the KMT Stack, before any administrator or agency. HubSpot’s bill also grows with every contact tier and every seat; the KMT Stack’s does not. Try your own numbers on the pricing page.
We have one marketer. Is the KMT Stack too much for them?
No. It is built for exactly that: a small team, often one person who does all the marketing. Grep drafts the work and answers how-do-I questions on the screen they are on, and for the first 90 days a senior marketing technologist builds the first automated follow-ups with them.
What happens when our marketer leaves?
The knowledge stays. How the platform is set up, who your customers are, what has been tried and the decisions made all live in the system. Your next hire needs marketing skills, not platform skills: they ask Grep how things are done here and are productive in days.
We are on HubSpot today. What moves across?
Your contacts come across with their company links, and your forms are rebuilt in the platform and put on your website. The platform is usually live within the first week, and your team learns it over the first 90 days by doing the work alongside us.
Can we keep HubSpot’s CRM?
Talk to us about it on the first call. The KMT Stack includes its own CRM, connected to marketing automation and analytics, and that connection is where most of the value is, so we look at what your sales team needs before recommending anything.
