Twilio may acquire Segment for $3.2B. Segment provides APIs to pull together customer data from various sources. While Twilio’s main focus has been on making communication APIs, it signaled a switch in direction when it released the Flex customer service API. Later, it bought an email marketing API company SendGrid. Now, it plans to combine its core API mission with Segment’s ability to pull customer data and create customized email or ads with SendGrid.
