ABsmartly

ABsmartly is the closest thing to a second Kameleoon in this category: a dedicated, full-stack experimentation platform rather than a bundle bolted onto marketing software, built specifically to compete with Optimizely, Statsig and LaunchDarkly on engineering-grade experimentation.

It was founded by Jonas Alves, who spent seven years architecting the experimentation platform behind Booking.com, scaling it past 1,000 concurrent experiments — a pedigree not many European vendors here can claim. Its headline feature is Group Sequential Testing, which lets a team check results daily without inflating false positives, reaching significance 20% to 80% faster than a fixed-horizon test.

The company is ABsmartly B.V., registered at Keizersgracht 520 H in Amsterdam.

Unlike most of this category, ABsmartly states its security posture rather than leaving it implicit: its information security management system is certified against ISO/IEC 27001:2013, and the platform is also SOC 2 Type II, GDPR and HIPAA compliant, with independent penetration testing stated. That combination — ISO 27001 plus SOC 2 — is matched only by Kameleoon among the tools in this directory, which states HIPAA compliance as well.

The gap is transparency about infrastructure and price. ABsmartly's own sub-processor list names Amazon Web Services as its cloud host with no EU region specified, so "Dutch company" does not automatically mean "EU-hosted data" the way it does for Varify.io.

There is no public pricing page — it redirects straight to a demo request — and no free trial, only a paid 30-day Proof of Value ahead of a yearly subscription. On-premises deployment is offered for teams that want to sidestep the hosting question entirely, at the cost of running it themselves.

What ABsmartly does well

• ISO/IEC 27001:2013 and SOC 2 Type II, matched only by Kameleoon in this category
• Group Sequential Testing reaches significance 20-80% faster than fixed-horizon tests
• Built by the team that scaled Booking.com to 1,000+ concurrent experiments
• On-premises deployment available for teams that want the data entirely in-house
• States GDPR and HIPAA compliance, with independent penetration testing

Where ABsmartly falls short

• No public pricing at all; the pricing page redirects straight to a demo request
• No free trial; the 30-day Proof of Value is paid
• Named cloud sub-processor (AWS) is US-based with no EU region stated
• Not open source; marketers get a visual editor only through the LaunchPad browser extension

Standout feature. Its ISO 27001 and SOC 2 combination, paired with Group Sequential Testing, targets the same engineering buyer as Optimizely Full Stack.
