Heterogeneous AI stack that grows your sales without adding new team members

Leveraging heterogeneous AI stack allows an enterprise to run more than one model and more than one runtime (some cloud, some self-hosted, some on users’ devices) behind a switching layer. As an organization, you get to pick the best tool for each job — then keep the power to change your mind.

At $25M ARR, Performance shifted 40% of templated copy to a self-hosted 8B model and cost/email fell by 82%.

The big reason for doing this is because it impacts your board directly. This specific design lowers cost per output, improves resilience, reduces vendor lockin, and helps compliance.

For an organization with a revenue of $20–30M, this is the fastest way to:

• Increase qualified pipeline by 10–15% realistically
• Shorten sales cycles by 10–20%, and
• Cut down on content production costs by 70–90%, with a total program budget of ~$350–500k/year and 4–9 months payback.

What does “heterogeneous” looks like?

Think of your AI as a sales bench:

• Premium closed AI models that act like your Star Closers. They are for hard tasks like complex writing, nuanced reasoning, highstakes customer copy.
• Open models you can selfhost who are more like Reliable Role players. Use them for highvolume, templated work: product descriptions, multivariant ads, SEO snippets, call notes.
• Ondevice models on AI PCs or phones that looks like Rookies on the floor. They are more for private, immediate tasks: meeting notes, quick summaries, redaction — no cloud roundtrip.
• Orchestrator or the agent layer that are more like your coach that routes each play to the right player, logs everything, and swaps in a backup when needed.

Here are five revenue workflows that you can implement today to help you gain more sales using the Heterogeneous AI stack:

1. Account Based Personalization but at a scale Create persona specific emails, ads, pages, and sales one pagers. Use premium model for first “voice” set; an open model for variants at volume; and a CMS plugin for instant page spin ups.
2. SDR Co Pilot with Inbox Agent Draft or rewrite replies, propose next best action, auto book with calendar and CRM context. Get on device for note capture; self hosted model for PII heavy enrichment; premium model for any tricky objections.
3. Sales Engineering Assistant RAG (retrieval) over docs, price books, competitive notes; export answers into emails/proposals with citations. Leverage a self hosted model for internal data and premium for customer facing polish.
4. Proposal or RFP Builder with Guardrails Pull relevant content, fill compliance sections, keep brand and legal language consistent and auto attach content credentials. Use premium model for structure/tone, open model for bulk drafting and on device watermark checker for reps.
5. Deal Intelligence Summarize discovery calls, flag risks, generate mutual action plans, update CRM. Use on device transcription/summarization, self-hosted for PII, premium for executive summaries.

A heterogeneous stack is an operating posture. For an enterprise it’s the cleanest path to near term revenue lift with controlled risk:

• Route each task to the cheapest model that meets quality.
• Keep a self hosted escape hatch for volume and PII. Never send PII to a closed model.
• Always route low-risk summaries on-device
• Instrument everything.
