Convert Experiences
Convert Insights Inc. · United States · since 2009
Bootstrapped, privacy-first A/B testing and personalization platform for CRO agencies and experimentation practitioners who want enterprise-grade statistics and 90+ integrations at published mid-market prices.
Best for Agencies and practitioners who will be asked to defend the statistics behind a result
The verdict
Convert wins five matchups by pairing the strongest statistics behind Apex and Optimizely, sequential testing on confidence sequences, Bonferroni and Sidak corrections and a sample-ratio-mismatch check on every plan, with a published price list and a 15-day trial. It loses to Apex on commerce testing and privacy, and to Varify on price and hosting, because the 100,000 tested-user cap sends a high-traffic shop into overage blocks where Varify charges a flat rate. Its entry plan also withholds the sequential testing its reputation rests on.

Strengths
- The most rigorous statistics engine in its price class, sequential testing built on published confidence-sequence research, Bonferroni/Sidak corrections, SRM check in every plan.
- Published, honest pricing with anti-lock-in policies: overage charges can be switched off, legacy plans honored, no forced upgrades.
- Strong compliance paperwork: SOC 2, ISO 27001, EU AWS hosting, free DPA, documented pen testing, clears enterprise security questionnaires on published evidence.
- Agency-native commercials: one account serves many clients with no extra licences, plus a written pledge never to poach agency clients.
- Breadth without modules: full-stack testing, feature flags, personalization, bandits, heatmaps and 90+ integrations included rather than sold as add-ons.
- Independent and bootstrapped since 2009, while VWO and AB Tasty consolidated under private equity in January 2026.
Weaknesses
- Tested-user pricing punishes traffic: 100K/month cap on both Growth and Pro, then $399–$699 overage blocks, high-traffic shops pay far more than on flat-rate tools.
- The entry plan is genuinely limited: no geotargeting, no multivariate, no full-stack/feature flags, no sequential testing, no SSO.
- Public GDPR documentation is stale (written in future tense about May 2018) and the hosting region differs between Convert’s own pages.
- No documented cookieless delivery and no Google Consent Mode integration, a real gap on consent-heavy EU sites.
- The Shopify app has zero App Store track record (0 reviews since Oct 2024) while requesting broad scopes.
- USD, tax-exclusive pricing adds currency risk for EU buyers.
The facts
| Statistics | The deepest stats in this comparison: t-tests with configurable tails, Bonferroni/Sidak corrections, Bayesian with explicit risk thresholds, and real sequential testing via Asymptotic Confidence Sequences (Pro+). SRM check on every plan. |
| Shopify | Native Shopify app (free to install, launched Oct 2024, still 0 reviews) that injects the script without theme edits and is compatible with checkout extensibility, for tracking, not checkout-UI editing. Price testing and multi-arm bandits included. |
| Privacy & hosting | EU-hosted on AWS (security page: eu-west-1 Ireland; AI info page: Frankfurt, Convert’s own pages disagree). SOC 2 attested and ISO 27001 certified, free DPA. No documented cookieless delivery mode or Google Consent Mode integration. |
| Pricing | Growth $399/mo ($299 paid annually), Pro $599/mo ($420 annually), both capped at 100K tested users/month; overage from $399 per 100K. USD, tax-exclusive. 15-day free trial, no credit card. |
