HubSpot shows Starter at $7 against $20, for a limited time

The psychology

Why it nudges

HubSpot uses reference prices: the higher figure beside each price frames the lower one as a saving. The 'limited time' line has no end date, so we don't count it as urgency; it's a flag. Results are not public.

HubSpot Marketing Hub pricing, captured 16 Oct 2026 from the UK. The page defaulted to USD.

Honest nudge or dark pattern?

Grey area

Watch the line: an undated 'limited time' offer drifts towards fake urgency, and struck-through prices must be real list prices. See deceptive.design/fake-urgency.

Steal this, honestly

If you show a reference price, make it one customers actually paid.
Put an end date on any 'limited time' claim.
Say who the offer is for (here, new customers only).

What to test: Price with vs without the reference figure. Measure Starter purchases and churn at month 3.

Next: run it on your product

You are helping me apply a behavioural-design pattern ethically.

Pattern: HubSpot: HubSpot shows Starter at $7 against $20, for a limited time
Bias: Reference price: A price is judged against a comparison price: a 'was' price, a monthly rate, a renewal rate.
Why it nudges: HubSpot uses reference prices: the higher figure beside each price frames the lower one as a saving. The 'limited time' line has no end date, so we don't count it as urgency; it's a flag. Results are not public.
Our verdict: Grey area. Watch the line: an undated 'limited time' offer drifts towards fake urgency, and struck-through prices must be real list prices.

Rules: say a brand "uses" a tactic, never that it "worked"; outcomes are not public unless the company published them; no invented uplift estimates; flag mixed evidence. Honest nudge = true, visible, easy to reverse, and in the user's interest. Dark pattern = hides costs, fakes scarcity or popularity, shames, or makes leaving harder than joining. Quote company-published results as "X reports", with the source link, and don’t generalise them. Don’t cite retracted or failed-to-replicate studies as support (e.g. Ariely & Wertenbroch 2002). Don’t state study figures unless they’re on this page or in a source you can link. If an idea crosses the line, link the matching deceptive.design pattern.

Tasks:
1. Ask me for my product, the flow (URL or screenshots) and the goal.
2. Audit where this pattern already appears, or could, in that flow.
3. Propose 2-3 ethical experiments: hypothesis, variant copy or UI, primary metric, and a guardrail metric (refunds, complaints, cancellations).
4. Flag every dark-pattern risk and say how to stay on the honest side.

ChatGPT, Claude, Grok and Cursor open with the prompt filled in (it is also copied, in case the prefill doesn't load). Gemini and Codex don't support prefilled links, so the prompt is copied and the app opens; paste it in.
