OverviewFacts verified August 2026

Inflection pricing and plans

Plan	Price	What it includes	What that works out at
Published entry point	From 36,000 USD a year	Unlimited contact database, unlimited product data, unlimited Salesforce API calls, and free unpersonalized batch sends to ten times the MMC allowance	At the 25,000 MMC end of the slider, 36,000 USD a year is about 1.44 USD per marketed contact per year, or 3,000 USD a month.
Custom	Quoted on request	Higher Monthly Marketed Contact volumes, up to a stated 10,000,000 on the pricing slider

The entry point is 36,000 USD a year, which is a real published floor rather than a quote-only process.
Cost is driven by Monthly Marketed Contacts, not by database size, so holding records you do not message does not raise the bill.
The pricing slider spans 25,000 to 10,000,000 MMCs, and anything above the published floor is quoted.
Unpersonalized batch sends to ten times your MMC allowance are included at no extra charge.

Priced on Monthly Marketed Contacts rather than database size, so the bill follows who you actually message rather than how many records you hold.

Inflection features: what it does

Built for full lifecycle marketing across prospects and customers, rather than treating post-sale as someone else's problem
Accessible via Slack, Claude, ChatGPT and an MCP server, so the tool reaches people where they already work
Purpose-built agents for audience building, campaign drafting, journey mapping, account scoring and reporting
Strong product-led customer references including Clay, Amplitude, DigitalOcean, Sentry and Mural

Inflection limitations

Exposing marketing automation through assistants and an MCP server widens the access surface and needs a permissions decision, which the public material does not address
No pricing published, so cost cannot be assessed without contact
Replacing an incumbent automation platform is a migration project, and the public material does not describe integration with Salesforce or HubSpot
Published outcomes such as 28 percent more product logins are uncontrolled customer figures

Who Inflection is for

Your situation	What that means here
B2B team with a costly legacy platform	Built explicitly to replace Marketo-era tooling whose maintenance exceeds its return.
Product-led company	Full lifecycle across prospects and existing users, rather than treating post-sale as someone else's problem.
Security-conscious organisation	Exposure through Slack, assistants and an MCP server widens the access surface, and the public material does not address permissions.
Company needing implementation partners	A large partner ecosystem does not exist, and migration is exactly when that is felt.
Team living in Slack	Reaching marketing tooling from where people already work removes the login friction that kills adoption.
Salesforce or HubSpot-centric business	The public material does not describe integration with either, which is a significant unknown for B2B.

Inflection use cases for marketers

Product-led lifecycle marketing spanning prospects and customers rather than stopping at the sale.
Campaign drafting, audience building, journey mapping, account scoring and reporting through purpose-built agents.

Inflection FAQ

Is MCP and assistant access a feature or a risk?

Both, and the ratio depends on scoping. Requesting a segment from Slack removes real friction. It also adds surfaces from which someone can act on customer data and send messages. Decide what needs the application, and who approves a send.

How hard is replacing Marketo or a similar platform?

Harder than any migration page suggests, and rarely for technical reasons. Programme logic accumulated over years is undocumented and the people who built it have left. Budget a parallel period rather than a cutover.

Does it work with Salesforce or HubSpot?

Not stated in the public material, which is a notable omission for a B2B platform. Lead routing, opportunity data and closed-loop reporting all depend on it. Establish which CRM objects sync, in which direction and how often.
