Reeba Selects Optiblack as Technology Partner to Launch Zeroh Online
Reeba partners with Optiblack to launch Zeroh, a clinically backed natural sweetener, enhancing its direct-to-consumer online presence in India.
Bengaluru, India — June 22, 2026 — Reeba today announced that it has appointed Optiblack as its technology partner to build and scale the direct-to-consumer (D2C) online presence for Zeroh, its clinically tested natural sweetener. The partnership brings together Reeba's science-led wellness brand and Optiblack's data and growth engineering expertise to take Zeroh from shelf to screen for health-conscious consumers across India.
Zeroh is a monk fruit and allulose blend positioned as a 1:1 replacement for regular sugar, with no erythritol, no bitter aftertaste, and negligible post-meal glucose impact. It is among the first sweeteners of its kind in India backed by a CTRI-registered randomised controlled trial, conducted at MGM Medical College, Aurangabad, where participants recorded a markedly lower post-meal glucose reading versus regular sugar. Manufactured to FSSAI standards, Zeroh is designed for people managing diabetes, prediabetes, PCOS, and weight, as well as anyone looking to cut sugar without sacrificing taste.
As a technology partner, Optiblack will lead the design and build of Zeroh's online store, set up the analytics and measurement stack, and engineer the growth infrastructure that connects marketing spend to revenue. The scope spans a conversion-focused storefront, a clean data foundation for tracking the full customer journey, and experimentation frameworks to optimise acquisition, retention, and repeat purchase — the core of Optiblack's "Data to Dollars" approach and its Data Accelerator framework.
"Reeba is solving a genuinely important problem for Indian households, and a product this well-validated deserves a digital launch to match," said Vishal Rewari, Optiblack. "Our job is to make every rupee of marketing accountable and every customer interaction measurable, so Zeroh grows on the strength of its results, not guesswork."
The collaboration reflects a broader shift among emerging Indian wellness brands toward analytics-first D2C launches, where product analytics, attribution, and experimentation are designed in from day one rather than bolted on later. By pairing a clinically backed product with a modern data stack, Reeba and Optiblack aim to set a benchmark for how health-focused consumer brands market themselves online.
The Zeroh online store is being rolled out in phases, with the analytics and growth infrastructure live from launch.
