When it comes to raising the bar of your customer satisfaction, we will help you understand your audience, anticipate their needs and act on them in real time. This will allow you to create a better product or service, bringing in more loyal customers and, eventually, sustainable revenue flows.

Design a recommendation engine

We can design a recommendation engine to increase the sales with ML algorithms and collaborative or content-based filtering. Our experts applying machine learning models such as FAISS, NMSLIB for similarity search. Your customers shall be happier with relevant product offers, personalized web-page content and promo offers.

Build and opportunity or threat scoring

We can build and opportunity or threat scoring for customers and products, so your sales team can design and optimize business strategy accordingly their efforts priority. Our experts perform cutting edge resampling algorithms (SMOTE & Tomek links, ADASYN) to handle imbalanced data, when outcomes of interest are very rare. Also, we use modern unsupervised learning algorithms such as HDBSCAN for automated clustering and segmentation.

Create a model

Besides, we can create a model to make your communication with customers stellar. Trained to detect attitude markers and recognize your customers’ mood, the model will signal your sales team if a particular customer experiences negative emotions. Also using Gradient Boosting techniques we can extract the most influent features for these changes.
