Here’s a sign that customer data is increasingly important: open source database vendor Couchbase has introduced a “engagement database” that is says is new class of system, distinct from transactional and analytical databases. It’s optimized for real time interactions at scale, with key features including in-memory data, full text search, and mobile deployment. They’ve written a helpful white paper explaining the details.

B2B profiling vendor MarianaIQ was built from the start on using artificial intelligence to identify buyer personas. They’ve just announced a neural network-based model to help companies find new target accounts. Also new: a targeting option for Google AdWords, which joins existing Twitter and Facebook ad capabilities.

Just over half of consumers (54%) like to receive personalized messages because they show the consumers are known to the brand, plus they can be time savers. The rest (46%) find it at best unimportant, at worst creepy. Relevance far outstrips personalization when it comes to driving email opens (54% vs. 19%). Takeaway: treat each customer the way they prefer.
