About Helco
We're a team of data scientists, content strategists, and growth engineers building the world's most rigorous content testing framework.
Born from Frustration With Unscientific Content Marketing
Helco was founded in 2022 by a team of performance marketers and data engineers who were tired of seeing great content strategies fail because of poor testing methodology. We'd seen too many brands scale the wrong formats because they interpreted misleading test data.
We set out to build something different: a content testing framework as rigorous as clinical trial methodology, but fast enough for the speed of social media. Three years and 12,000+ tests later, that framework has helped 98 brands systematically scale their best content.
Based in Roppongi, Tokyo — a neighborhood that defines our design philosophy: structured, clean, precise, and built to last.
Our Core Principles
The values that guide how we design testing frameworks, work with clients, and build the Helco Lab platform.
Data Over Intuition
Every scaling decision must be backed by statistically significant test data. Gut feelings are hypotheses — not conclusions. We only scale what the data confirms.
Rigorous Methodology
We apply the same statistical standards as academic research — proper controls, significance thresholds, and protected against bias at every step of the test design.
Speed Without Shortcuts
Fast iteration doesn't mean sloppy testing. We've built workflows that move quickly while maintaining statistical integrity — you don't have to choose between speed and quality.
Transparent Reporting
We report all results — including tests where nothing won. Negative results are as valuable as positive ones. Full transparency is the only way to build genuine learning systems.
Platform Agnosticism
The best content format is the one that wins on your specific platform for your specific audience. We don't have preconceived ideas about what format should win — we find out what does.
Compound Learning
Every test we run adds to a growing body of knowledge about your brand's content. The longer you work with us, the faster your testing cycles become and the bigger your average wins get.
Built by Data Scientists & Content Strategists
Our team brings together expertise in statistics, growth marketing, social content, and platform engineering.
Aiko Kuroda
Former Head of Growth at a $2B DTC brand. Statistics PhD dropout who found that content testing was more interesting than academia.
Raj Mehta
Built data infrastructure at two unicorns. Architect of the Helco platform's real-time test monitoring and automated scaling systems.
Sara Park
10 years in social content for global brands. Developed the Creative Variation Framework that underlies every Helco client engagement.
Tom Wright
Statistician specializing in sequential testing and Bayesian inference. Designed the confidence scoring models used in all Helco experiments.
The Content Funnel Visualization
Every content piece enters our testing funnel and only exits when it's been validated with sufficient data. The funnel ensures we never scale based on incomplete signals.
- Minimum impressions threshold at every stage
- Confidence level gates before advancement
- Automatic rejection for statistically insignificant variants
- Winner archive for trend analysis over time
From Hypothesis to Scaled Winner
Every content variant goes through four gates before it earns scaling budget. Most don't make it — and that's the point.
All Content Variants
100% of generated variants enter the funnel
Pass Quality Gate
~65% meet minimum quality threshold
Achieve Significance
~30% reach 95% statistical confidence
Scale-Ready Winners
~15% become scalable content formats
