Proprietary CRM software

Tesla is set to abandon Salesforce for a proprietary customer-relationship-management system. Lyft, a less known competitor of Uber, is also programming its own marketing automation solution to make a shift. Volkswagen strives to develop 60% of coding in-house by 2025. Are these telltales of a trend away from outsourcing data-management to big software service providers? The reason given by Tesla employees is, “Tesla’s decision to develop its own CRM system aligns with its desire for vertical integration and continues a trend toward making its own software for internal functions rather than using third-party systems. Volkswagen CEO Herbert Diess did announce that the global leader in car making wants to be independent in the field of software.
Lyft blogged that by automating routine decisions, they can scale efficiently and create a data-driven learning system. This also lets marketers concentrate on innovation and experimentation instead of operational activities. Lyft’s goal is to build a marketing automation platform to improve cost and volume efficiency while enabling the marketing team to run more complex, high-impact experiments.
