BigCommerce is a SaaS ecommerce platform built for scaling and headless D2C brands. CustomFit personalizes and experiments across Stencil and headless BigCommerce builds alike, with zero added latency.
Read BigCommerce catalog, orders, and customer groups; push experiment data back through the BigCommerce API.
Install via the BigCommerce app or one Script Manager snippet — no Stencil theme edits required.
Run a Stencil theme or a headless storefront with BigCommerce as the backend — CustomFit personalizes both.
BigCommerce runs your store. CustomFit.ai is where you act on it — building cohorts, running A/B tests, and personalizing experiences without engineering tickets. Together they close the loop from observe → hypothesize → test → ship → measure in days, not quarters.
Total transparency on the data we read and write. Every field is configurable, every event is logged, and you control retention.
Pull BigCommerce customer tags, order history, and cart signals into CustomFit targeting, then personalize the storefront for each segment in real time.
Variant assignment and conversions flow back automatically, so each experiment's lift is measured against real BigCommerce revenue.
Observe in BigCommerce, hypothesize and test in CustomFit, ship the winner, and feed results right back — no spreadsheets in between.
BigCommerce is a SaaS ecommerce platform built for scaling and headless D2C brands. Once connected to CustomFit.ai, BigCommerce data flows in to build audiences and target experiences, while experiment exposure and conversions flow back — no spreadsheets and no glue code, just one connected loop between your store and your storefront.
The BigCommerce integration connects your BigCommerce data to CustomFit.ai so growth and CRO teams can run A/B tests, personalize experiences, and measure revenue impact without engineering work. Instead of exporting CSVs or maintaining brittle scripts, BigCommerce and CustomFit stay in continuous two-way sync — audiences and events flow into CustomFit, and experiment exposures and conversions flow back to BigCommerce.
For D2C and ecommerce brands, pairing BigCommerce with CustomFit closes the optimization loop: you observe behavior, form a hypothesis, build a test or personalized experience in a no-code editor, ship it, and measure the lift against real outcomes. Because evaluation happens at the edge before first paint, the BigCommerce integration adds no visible latency and keeps Core Web Vitals healthy.
Setting up the BigCommerce integration takes minutes, not sprints. Connect via OAuth or an API key, map the fields and events you care about, and turn on sync — every field is configurable, every API call is audit-logged, and you stay in control of data retention. Security is enterprise-grade: SOC 2 Type II, ISO 27001, GDPR and CCPA alignment, with encryption in transit and at rest.
