The bootstrapped, privacy-first A/B testing platform — no third-party data sharing, transparent pricing, and a real alternative to Optimizely for mid-market teams
Convert.com is the experimentation industry's best-kept open secret: a fully bootstrapped, privacy-first A/B testing platform founded in 2009 by Dennis van der Heijden, with an engineering hub in Bucharest, Romania and a distributed global team. It is not a feature-flagging platform (do not pick it for that), it does not sell or share visitor data with third parties (a real differentiator post-GDPR), and its pricing is fully transparent and tiered on tested-user volume rather than seats. Convert sits in the same competitive bucket as Optimizely Web Experimentation and VWO, but it is meaningfully cheaper at the entry tier ($199/mo billed annually) and is the default tool of choice for many international CRO agencies. For Indian growth and CRO teams, the trade-off is straightforward: pricing is USD + GST, but you get a mature, EU-friendly stack that won't quietly become a 6-figure annual line item like Optimizely will at the enterprise tier.
Convert.com — the company name in product is "Convert Experiences" — is a web-based A/B and multivariate testing platform aimed at e-commerce, SaaS and publishing teams. The company was founded in 2009 by Dennis van der Heijden together with a co-founder he met in Bucharest, and has operated as a bootstrapped, profitable business ever since — meaning no VC pressure to bolt on a feature-flagging product or a personalisation engine to chase a growth narrative. That focus shows up in the product: Convert is good at the thing it sells (A/B + MVT testing on web), and it does not pretend to be a Statsig-style data platform or a LaunchDarkly-style feature-flag store.
The "privacy-first" positioning is not just marketing. Convert publishes a clear data-processing posture: no third-party data sharing, GDPR-aligned defaults, the option to keep all visitor data in the EU, and a public sub-processor list. For European e-commerce brands and any Indian SaaS business that sells into Europe — which is most of them now — this materially reduces the legal-review surface compared to a US-headquartered Optimizely or AB Tasty deployment.
Convert is heavily used by independent CRO consultancies and agencies. If you've worked with a freelance conversion specialist or a boutique CRO firm and ended up with a tool other than Optimizely or VWO, it was almost certainly Convert. That agency-driven distribution is a useful signal: Convert tends to land in teams that take experimentation seriously enough to hire an expert.
The core product. Run client-side A/B and multivariate tests against any web-funnel metric. Both Bayesian and frequentist statistical engines available; pick the one your team is comfortable with. Sample-size calculator and sequential testing supported.
WYSIWYG editor for marketers and CRO specialists to build test variants without engineering involvement. Slightly less polished than VWO's but more flexible than the bare-bones Optimizely Lite tier.
No third-party data sharing. EU data-residency option for European brands. Public sub-processor list. Built-in GDPR/CCPA consent handling. The single biggest reason CRO agencies serving European brands default to Convert.
Native integrations with Google Analytics 4, Adobe Analytics, Heap, Mixpanel, Amplitude, Hotjar, FullStory, Segment, and major e-commerce platforms (Shopify, BigCommerce, WooCommerce, Magento). Webhook + REST API for custom destinations.
Geography, device, traffic source, custom JS conditions, and integration-driven audiences (e.g. logged-in Segment users matching a trait). Sufficient for ~90% of CRO use cases — but if you need ML-personalisation, look at Dynamic Yield or Optimizely Personalisation instead.
JavaScript snippet for client-side tests, REST API and webhooks, plus an experiments-as-code option for engineers who'd rather check tests into git. No native server-side feature-flag SDK — for that, pair Convert with GrowthBook or LaunchDarkly.
Convert publishes its full price list — rare for the enterprise-testing category. Three tiers, gated by tested-user volume per month:
For Indian buyers: pricing is USD, with 18% IGST applicable. At ~₹84/USD the Entry tier works out to roughly ₹17K/mo ex-GST, ~₹20K/mo all-in. That's still meaningfully cheaper than Optimizely's enterprise floor (which routinely lands at $30K+/yr) and roughly on par with VWO's USD pricing tier. Always verify the live numbers on convert.com/pricing; this is a category where rates move once or twice a year.
Convert is the wrong call when you need: server-side feature flagging at scale (use LaunchDarkly or GrowthBook), ML-driven personalisation (use Dynamic Yield or Optimizely Personalisation), or experiment metric instrumentation tightly coupled to your warehouse (use Statsig or Eppo).
