HubSpot publishes real prices and a developer platform, but robots.txt seals the actual signup form away from every automated buyer, human or agent.

What a visitor actually meets

4 moments, 3 with friction, 1 blocking

We walked the funnel in a real browser and captured every step. Nothing was submitted and no account was created.

  1. 01

    Landing page

    Headline "Where go-to-market teams go to scale". It's clearly a CRM/marketing suite for businesses but exact product and price aren't stated up front. Two competing CTAs: "Get a demo" and "Get started free". A chat widget pops up immediately offering help, adding a third path.

    Pricing page

    Prices only render via JavaScript, nothing in raw HTML. Four tiers: Free $0, Starter $7/mo/seat, Professional $800/mo, Enterprise price further down. A chat bubble pushes "chat with a sales agent" over the self-serve figures. Big jump from $7 to $800 with no mid-tier.

    Signup attempt from pricing page

    Clicking "Get started free" opened a chatbot pushing "Book a meeting" or "Chat with sales" rather than a signup page. The actual form at app.hubspot.com/signup-hubspot/crm is disallowed by robots.txt for this scanner. An automated visitor cannot reach it.

    Developer platform page

    A separate developers.hubspot.com site exists with docs, API references, and a "Create developer account" button. This is a reasonable path for an agent integrator, but it is not linked from the main homepage nav, a visitor has to know to look for it. The main signup funnel and this developer funnel are disconnected.

We sent a buying agent

16 requests, in order

The agent got through 10 of 16 requests, but could not find a published agent interface. It came up empty on 5 other checks too. That is enough missing for a machine to give up before it reaches a purchase.

Ten dimensions

Not measured is not zero.

The agent door

40 of 100

What a machine can do on your site with nobody watching.

Machine discoverability

Whether a retrieval system can find and read you at all.

89Strong

Robots.txt allows all named AI crawlers, a real browser gets the page normally, and a sitemap lists 1062 URLs with 9 schema.org types on the homepage.

4 observations recorded.

Programmatic onboarding

Whether an agent can get working access without a human.

15Blocking

The signup path at app.hubspot.com is disallowed by robots.txt for automated clients, and no API key can be issued without going through it. Developer docs show endpoint examples but no documented key issuance or self-serve flag.

4 observations recorded.

Pricing legibility

Whether total cost can be computed from published numbers.

30Weak

16 prices from $0 to $3,600 render on the pricing page but only after JavaScript runs, with zero prices in raw HTML. A client that does not execute scripts, including many agents, sees no price at all.

1 observation recorded.

Agent-aware instrumentation

Whether you publish anything built for machine callers.

8Blocking

No MCP manifest at any of 3 standard paths, no ai-plugin.json, and no OpenAPI spec at any of 6 standard paths checked. An agent has to hand-write a client from prose documentation.

4 observations recorded.

Machine-fetchable trust

Whether terms, security and status are readable as text.

85Strong

security.txt is published with a working contact route, and the homepage answers automated requests cleanly with structured Organization and Product data in JSON-LD.

2 observations recorded.

Commercial rails

Whether a purchase can complete without a sales call.

10Blocking

Prices do exist and render for a browser, but the checkout path an agent needs to turn a price into a paid account sits at app.hubspot.com, which robots.txt disallows outright for automated visitors, and no machine readable pricing file or.

4 observations recorded.

The human door

80 of 100

What a first time visitor meets between landing and first value.

Steps to first value

How far a new visitor travels before something useful happens.

80Strong

The signup CTA is 2 clicks from the homepage, a short path by design, but robots.txt closes app.hubspot.com to automated visitors, so nothing past that click was actually read by the scan.

1 observation recorded.

Required fields

How much you ask for before you give anything back.

Not measured
