Sierra is one of the most prominent enterprise CX agent platforms — and, like osFoundry, it’s genuinely model-agnostic. The key difference is focus: Sierra is customer-facing CX; osFoundry is broad orchestration. Here’s a factual look for a US business, with sources cited. (dgm implements osFoundry, a separate company’s platform — we are not osFoundry.)
At a glance
| osFoundry | Sierra | |
|---|---|---|

| Models | Bring your own, any provider | Model-agnostic (15+ LLMs, routed) |
| Pricing | Via dgm: $399 / $3,999/mo (public) | Outcome-based; not public; enterprise |
| Scope | Internal + external, broad | Customer experience (chat/voice/messaging) |
| SaaS consolidation | Designed to consolidate | CX agent platform |
What Sierra is
Sierra is an enterprise conversational AI agent platform for customer experience, founded by Bret Taylor (former Salesforce co-CEO). It builds branded, company-specific customer-facing agents across chat, voice, email, SMS, and WhatsApp, connecting them to internal systems and policies, with a supervisory layer that enforces policy. It serves large enterprises and has grown rapidly.
osFoundry’s focus is broader and more internal: an orchestration layer for agents, automations, and apps with the explicit goal of consolidating overlapping SaaS — not specifically a customer-facing CX product.
Models
Both are genuinely model-agnostic. Sierra explicitly uses a multi-model architecture, blending 15+ LLMs from providers like OpenAI, Anthropic, and Meta and routing per task. osFoundry is likewise model-agnostic at the orchestration layer. So model flexibility is common ground; the difference is what the agents are for.
Security and data
Sierra states that customer data is isolated per customer and not used to train cross-organization models, with SOC 2, encryption, and access controls (these are vendor claims worth confirming in a security review). With osFoundry, dgm confirms the equivalent controls against your requirements during the integration assessment, so the review is explicit to your situation.
Pricing
Sierra uses outcome-based pricing and does not publish figures — it’s sales-led and enterprise-oriented. Third-party estimates suggest six-figure annual contracts, but these are unverified, so budget an enterprise sales cycle. dgm’s osFoundry engagement pricing is fixed and public instead: $399 assessment and $3,999/month integration, with no per-seat fees.
Customer-facing CX vs broad orchestration
The core difference is scope. Sierra is a specialist in customer-facing conversational agents — strong if your priority is enterprise CX across channels. osFoundry is a generalist orchestration layer that spans internal agents, automations, and apps and targets SaaS consolidation. If your need is specifically customer-facing CX at enterprise scale, Sierra is excellent; if it’s broad internal orchestration and consolidation, osFoundry fits better — and the two can be complementary (Sierra for the CX front end, osFoundry orchestrating behind it).
Who each is best for
Sierra is the stronger choice if your priority is enterprise-grade, customer-facing conversational agents across channels. osFoundry is the stronger choice if you want broad internal orchestration and SaaS consolidation with transparent pricing.
Which should a US company choose?
If customer-facing CX agents are your focus, Sierra is a leading, model-agnostic option. If broad orchestration and consolidation matter more, then osFoundry is the more direct fit. dgm assesses your goals, recommends the right path for a US business, and implements it end to end.
