Stop optimising for signups

Convultra captures user identifiers at trial signup (email, user ID) and stores the original attribution data. When your billing system fires a webhook for a new subscription, we match it back to the ad click that started the journey—even weeks later.

What you track:

Trial start event with user identifier

Activation milestones (first key action, usage threshold)

Subscription created event from billing webhook

Plan tier and MRR for value-based bidding

Activation events tell ad platforms to optimise for engaged users, not just signups. Common SaaS activation events include:

First key action: User completes core product task

Usage threshold: Hits meaningful usage milestone

Team invite: Adds team members (high intent signal)

Integration connected: Links external service

Send these events server-side via our API. We'll attribute them back to the original campaign.

For custom integrations today, use our API to forward Stripe webhook events:

``javascript // In your Stripe webhook handler convultra.track({ event: 'Subscribe', user: { email: customer.email, external_id: customer.id }, properties: { value: subscription.plan.amount / 100, currency: subscription.currency.toUpperCase(), plan_name: subscription.plan.nickname, billing_period: subscription.plan.interval } }); ``

Native Stripe integration coming soon—just connect your account and we'll handle the rest.

Yes! Expansion revenue is crucial for SaaS unit economics. Track these events:

Plan upgrades: User moves to higher tier

Seat additions: Team size increases

Feature upsells: Add-on purchases

Annual conversion: Monthly to annual switch

We attribute expansion revenue back to the original acquisition source, so you know which channels bring customers who grow over time.

SaaS trials can last 14-30 days, and conversions can take even longer. Convultra solves this by:

1. User-based attribution: We track by user ID, not cookies 2. Server-side events: No browser required for conversion tracking 3. Extended windows: Attribution persists across the full customer journey 4. Cross-device: Same user on different devices still gets attributed

When someone converts weeks later, we attribute it to the campaign that first brought them in.
