Close the gap between signup and revenue.

Helix watches how every freemium user behaves, predicts who's ready to upgrade, and triggers the exact nudge that moves them to paid — without a PM, a data team, or a six-month rebuild.

What it does

Three things, done exceptionally well.

01

Behavioral scoring

Every user gets a live upgrade-readiness score based on the activation signals that actually predict revenue in your product — not vanity events.

02

Triggered upgrade paths

The moment a user hits a threshold, Helix fires the right in-app message, email, or Slack ping — tailored to the feature they almost used.

03

Revenue attribution

See exactly which triggers turned free users into revenue — down to the headline, the timing, and the cohort. No more guessing which nudge worked.

How it works

From snippet to revenue in under a week.

I

Drop in one snippet.

Add the Helix SDK to your app in under five minutes. It auto-detects your existing product events — no new tracking plan required.

II

Helix learns what converts.

Within 72 hours, Helix builds a model of which behaviors actually lead to paid conversion in your specific product. Not a generic template.

III

Revenue starts showing up.

Helix fires the right nudge at the right user at the right moment. You watch the upgrade notifications hit your Slack while you do other things.

Questions

Things founders usually ask before they sign up.

How fast can we get value from Helix?+

Most teams see their first predicted-upgrade cohort populated within 72 hours of installing the SDK. Your first revenue-attributed trigger typically fires within the first week, assuming you have at least 500 active users per week.

Do we need a data team to use this?+

No — that's the whole point. Helix auto-detects your existing product events and builds a conversion model without any tracking plan work. If you already have analytics, you already have enough.

What happens to the data Helix collects?+

Your data stays yours. We process events in-region (US or EU), never sell or share it, and you can purge your workspace at any time. Full SOC 2 Type II and a signed DPA are included on Growth and above.

Can Helix replace our current analytics tool?+

Not really, and we don't want to. Helix is purpose-built for conversion triggers. Keep your analytics tool for dashboards and funnel reports — we'll sit on top and drive the upgrade actions.

What's a 'tracked user'?+

Any unique user who generated at least one product event in the last 30 days. Users who go dormant stop counting automatically. Anonymous visitors don't count.

Can we cancel anytime?+

Yes — monthly plans cancel on the spot, annual plans cancel at the next renewal. No clawbacks, no dark patterns, no "schedule a call to offboard."

Ready?

Stop losing money on traffic that never upgrades.

Install the SDK, let Helix watch for 72 hours, and see your first predicted-upgrade cohort. If it doesn't pay for itself in the first quarter, we refund everything.
