Messaging Vendors Converge on Customer Record
Customer.io
The key pattern is that messaging vendors keep moving toward the customer record, because whoever owns the system of record keeps the account as teams and workflows multiply. HubSpot started with inbound marketing, then added a free CRM in 2014 so marketers and sales reps could work from the same contact history. Salesforce reached the same outcome from the other side, folding Pardot into the ExactTarget business it bought in 2013, so CRM data and marketing automation could live in one stack. Customer.io sits earlier on that same path, using messaging and event data as the wedge into product-led companies.

In practice, a CRM is the shared customer table. It stores the contact, company, activity log, deal context, and message history in one place. That matters because once a company adds sales, support, and revops staff, email tools alone stop being enough. HubSpot turned its marketing suite into a broader operating system by adding that shared record.

Salesforce got there by acquisition rather than internal build. Pardot was acquired by ExactTarget in 2012, then Salesforce bought ExactTarget in 2013. That gave Salesforce a B2B marketing automation layer connected to its CRM, which is why Pardot became part of the larger Marketing Cloud story instead of remaining a standalone email tool.

Customer.io already has some CRM-like ingredients, it builds user profiles from app events, lets teams segment by behavior, and ties message history back to each user. But its strength is with technical growth teams. As those customers add more non-technical marketers and sellers, the pressure rises to either add more shared system of record features or integrate deeply with existing CRMs.
The next step in this market is tighter bundling around the customer record. HubSpot is adding more data and operations layers around its CRM, and Customer.io is expanding from Journeys into Data Pipelines to control more of the flow from product event to customer profile to outbound message. The vendors that make that shared profile usable by both engineers and non-technical teams will keep customers longer and move further upmarket.
