You can't optimize what you're not testing.
Intempt runs web, mobile, and server-side tests with CUPED variance reduction, cutting time to statistical significance* so you can run more tests per quarter on the same traffic.

Reach significance faster on the same traffic.
Standard A/B tests need a lot of traffic and a lot of time. CUPED uses pre-experiment behavioral data to reduce variance, meaning your tests reach significance 20–40% faster* without inflating false positive rates.
- CUPED applied automatically to all eligible experiments
- Faster time to significance without compromising statistical rigor
- Sequential testing mode to avoid peeking inflation

40% faster
Same significance threshold. No false positive inflation.
Test deeper than just the UI.
Some of your most important experiments aren't visual. Intempt's server-side experiments let you test pricing, feature access, recommendation logic, and backend behavior with the same statistical rigor as front-end tests.
- Choose API for server-side experiment assignment
- Mobile A/B tests for iOS and Android
- SDK-level experimentation for native app experiences

The teams that made the switch
“We were losing visitors before they signed up. Intempt's personalized experiences changed that - we started meeting people where they were instead of guessing. Once they're in, Intempt's automated email takes over and keeps the relationship moving. Acquisition and retention finally feel like one connected motion instead of two separate problems.”
Jim Stromberg, CEO
StockInvest
Case Study
StockInvest needed to turn anonymous traffic into registered users before any retention strategy could work. With Intempt's Experiences, they personalized the anonymous visitor flow, surfacing the right content and CTAs to boost signup conversion. Once users signed up, automated Journeys nurtured them through onboarding and deeper engagement, steadily increasing lifetime value.

* CUPED (Controlled-experiment Using Pre-Experiment Data) achieves 7–45% variance reduction depending on covariate selection. Deng et al. (Microsoft Research, 2013); Eppo, Statsig documentation (2024–2025). The 20–40% figure reflects typical production deployments.
