Stensul Launches Bring Your Own LLM, Enabling Customers to Run Their Own LLM Inside a Governed Workflow

New capability brings customers' own AI infrastructure inside Stensul's governance layer

NEW YORK--(BUSINESS WIRE)--Stensul, the Governed Creation™ platform for enterprise marketing teams, today announced the launch of Bring Your Own LLM (BYO LLM), a new capability that allows customers to connect their own proprietary or licensed large language model (LLM) to Stensul's governed templates and workflows. With BYO LLM, all AI requests in Stensul route through the customer's managed environment, so teams in regulated industries can adopt AI-powered content creation without stepping outside their approved AI environment.

BYO LLM keeps the Stensul creation experience identical for marketers — they work from production-ready templates assembled from approved modules and prompt AI directly from the template to draft copy, write subject lines, or rewrite sections. Because the template is already aligned to brand, compliance, and channel requirements, every AI-generated output lands in a structure that's ready for production from the start. This makes BYO LLM particularly valuable for financial services, healthcare, and life sciences teams operating under strict AI governance requirements.

The difference is under the hood: customers connect their existing LLMs — including OpenAI's GPT, Anthropic's Claude, and Google's Gemini — via major cloud providers, so each AI request is processed inside their managed environment, under their existing contracts and controls, and never leaves their environment. The output returns to the Stensul editor and enters the same governed workflow as any other content — brand guardrails, content validation, and approval workflows all apply — so teams get the benefits of AI-assisted creation without relying on an outside AI provider.

"Stensul has always been about speeding up creation by optimizing workflows and enabling more people to create without compromise on governance, brand, or compliance,” said Rachel Meranus, Chief Revenue and Marketing Officer at Stensul. "With the proliferation of AI, governance is even more critical. But we recognize that for many of our customers — particularly those in regulated industries — AI can only run through the models their organization has already vetted and approved. Bring Your Own LLM lets teams prompt their own approved model directly from a Stensul template, so the creation, governance, and collaboration still happen inside our platform — the only thing that changes is which AI is doing the generating."

Governance built in — wherever enterprise marketers work

BYO LLM reflects a broader design principle at Stensul: governance should follow the marketer, not the other way around. Enterprise teams don't work in a single tool, and Stensul is built to bring Governed Creation™ into the environments they already use.

Stensul's native Adobe GenStudio for Performance Marketing integration surfaces Stensul templates directly inside GenStudio's email creation flow, where marketers select a governed template as a starting point, prompt GenStudio to generate multiple draft variations with AI-generated content, and sync their chosen variant back to Stensul — where guardrails and approval workflows ensure it's production-ready before Stensul pushes the final HTML to an ESP for deployment.

Stensul's Figma plugin brings that same governed foundation into the design workflow. Designers select Stensul templates and approved modules directly in Figma, make visual updates in their preferred environment, and push work back to Stensul — where brand guardrails, approval workflows, and content validation pick up from there.

Across each of these integrations — AI systems, content platforms, and design tools — Stensul's production-ready templates serve as the common foundation: pre-built from approved modules, already aligned to brand and compliance requirements, and ready to enter a governed workflow the moment content is placed inside them.
