Frequently Asked Questions
The timeline varies depending on complexity, but a typical project follows this path: a 2-4 week discovery and data audit phase, followed by a 4-6 week prototyping phase. The full solution development and integration can take 3-6 months. We focus on delivering initial value within the first quarter.
To build effective models, we typically need at least two years of historical data, including: daily or weekly sales/shipment data at the SKU-location level, inventory on-hand levels, purchase order history with lead times, and product master data. Data on promotions, pricing, and known stockout periods is also highly valuable.
This is a key strength of our approach. Our machine learning models are specifically designed to identify and quantify the impact of these factors. We use techniques that can isolate the effects of seasonality, promotions, holidays, and other recurring events to produce a more accurate baseline forecast and predict the uplift from future campaigns.
No, our goal is to augment, not replace, your expert team. The AI handles the complex, repetitive calculations for thousands of SKUs, freeing up your planners to focus on more strategic tasks like managing exceptions, collaborating with sales and marketing, negotiating with suppliers, and planning for new product launches. It turns them into strategic managers of an intelligent system.
Data security is our top priority. We are ISO 27001 and SOC2 certified, which means we adhere to the strictest international standards for information security management. All data is encrypted in transit and at rest, and access is tightly controlled. We work with you to ensure our solution complies with all your corporate security and data governance policies.
We offer comprehensive support and maintenance packages. This includes system monitoring, technical support, and, most importantly, periodic model retraining. Market dynamics change, so we regularly retrain the AI models with the latest data to ensure they maintain their accuracy and continue to adapt to your evolving business, ensuring long-term value from your investment.
