In MarTech’s “MarTechBot explains it all” feature, we pose a marketing question to our very own MarTechBot, which is trained on the MarTech website archives and has access to the broader internet.

Question: How might adopting an open semantic data standard like OSI change martech vendor selection and integration RFP processes?

MarTechBot’s answer: The adoption of Open Semantic Interchange (OSI) introduces a fundamental shift in how marketers will evaluate, compare and select martech vendors—particularly at the RFP stage, where integration complexity and data interoperability often make or break a deal.

At its core, OSI is an open framework for describing marketing data—campaigns, events, audiences and behaviors—in a consistent, machine-readable format. It’s not a platform or protocol, but a shared semantic model intended to make martech systems easier to integrate without custom code or brittle APIs. For B2B marketers accustomed to navigating multi-vendor stacks, data silos and lengthy IT timelines, OSI offers the promise of modularity and composability: tools that work together “out of the box” because they speak the same data language.

What that means for the RFP process

Today’s RFPs are still shaped by legacy assumptions: data structures are proprietary, integrations are manual, and platform compatibility must be interrogated at a deep technical level. Evaluations hinge on questions like “Can Vendor X connect to our CRM?” or “How long will it take to map fields from Platform A to Platform B?” These questions are proxies for a deeper issue—vendor-specific data complexity.

OSI challenges those assumptions. If a vendor’s data model aligns with OSI, then campaign metadata, engagement signals or identity objects can be passed between systems using shared definitions. This makes interoperability a baseline expectation, not a differentiator. In this environment, RFPs begin to evolve. Instead of asking if a platform integrates with others, buyers will ask whether it publishes and consumes OSI-compliant schemas. Instead of mapping dozens of fields across systems, marketers will expect OSI-native support for shared concepts like “campaign,” “touchpoint” or “conversion.”

In other words, semantic compatibility becomes the new interoperability test.

Shift from connectors to composability

Vendors that have historically relied on large libraries of proprietary connectors—or on expensive service engagements to customize integrations—may lose ground to newer entrants that build on OSI at the foundation. This shift incentivizes product teams to prioritize data clarity, extensibility and forward compatibility.

For example, a marketing automation platform that emits campaign performance data using OSI schemas could plug seamlessly into a CDP, analytics dashboard or AI model that consumes the same standard. Marketers gain flexibility to swap or layer tools as needs evolve, rather than being locked into bundled suites or brittle integrations.

This also makes ecosystems more dynamic. OSI could foster a more composable martech environment where tools can be evaluated independently but work together without bespoke glue code. That reduces technical debt and increases stack agility—a key advantage as marketing teams look to scale experimentation and automation.

Accountability and roadmap alignment

Another change: RFPs will increasingly examine a vendor’s roadmap and governance posture. Is the vendor contributing to OSI? Are they versioning their schema support? Do they commit to backward compatibility? These questions reflect a growing expectation that vendors behave not just as service providers, but as standards participants.

Conversely, vendors that avoid OSI may be flagged as higher risk. If their data formats are proprietary, if they gate access to key objects, or if they rely on opaque data pipelines, marketers may see that as a sign of future integration pain or limited portability.

Implications for MOps: This is not just a procurement shift—it has real implications for how marketing ops teams plan, build and manage workflows. OSI-compliant vendors lower the barrier to workflow automation across systems. Data onboarding becomes faster, audience targeting more precise, and reporting more consistent across channels. Over time, this may reduce dependence on IT and increase marketing teams’ autonomy to test and iterate at speed.

Bottom line

OSI adoption may turn integration from a technical hurdle into a strategic differentiator. As semantic compatibility becomes a core buying criterion, marketers will revise how they write RFPs, assess vendor roadmaps and structure their stacks. The result could be a more open, interoperable martech landscape—one where best-of-breed tools finally live up to the promise of working together more effectively.
