Enterprise foundation model pretraining

Enterprise Pretraining.
Done Right.

We help the world's most ambitious companies build, optimize, and continuously improve proprietary foundation models — with proven best practices that compound efficiency over time.

Built for enterprises that lead in Financial Services · Healthcare · Manufacturing · Legal · Technology

What we do

The pretraining partner for enterprises that intend to lead.

Four disciplines, one outcome: models that are yours, measurably better, and cheaper to train and run with every cycle.

01

Custom Pretraining

Build domain-specific foundation models from your proprietary data — owned by you, trained where your data lives.

  • Continued pretraining or from scratch
  • Distributed training at scale
  • Evaluation built from your workflows

02

Best-Practice Consulting

Adopt the highest-leverage training, data, and evaluation practices used by frontier labs — without years of trial and error.

  • AI maturity & data readiness audits
  • Playbooks and team enablement
  • Board-ready roadmaps
Learn more

03

Ongoing Optimization

Continuous improvement loops that lower cost and raise quality with every training cycle.

  • Cost and goodput optimization
  • Iterative retraining with regression gates
  • Efficiency that compounds year over year

04

AI Cost Optimization

Small and local models handle routine work; frontier models are reserved for deep reasoning. Up to 80% lower AI spend.

  • Workload audit and savings map
  • Evaluated task-to-model routing
  • Local models for high-volume tasks

AI cost optimization

Stop paying frontier prices for routine work.

Most enterprise AI traffic doesn't need a frontier model. We route classification, extraction, and summarization to fast, inexpensive models — many running on your own hardware — and reserve frontier models for the problems that demand deep reasoning.

80%lower AI spend1 — with quality held to thresholds you set.

  • Cache & rules

    Repeated queries, deterministic lookups

  • Small & local models

    Classification, extraction, reformatting, short summaries

    Lowest
  • Mid-size models

    Grounded Q&A, drafting from templates

    Moderate
  • Frontier reasoning

    Multi-step analysis, complex judgment, novel problems

Illustrative. Line weight shows relative request volume; low-confidence answers escalate automatically to a stronger model.

1 Savings depend on task mix, quality thresholds, and model pricing. Published research on LLM cascades has reported cost reductions of up to 98% on benchmark tasks (Chen, Zaharia & Zou, 2023). We baseline your own traffic before committing to a target.

How we work

A delivery system engineered to remove guesswork.

Every stage produces an artifact you keep, and every scale-up decision is backed by evidence gathered at a fraction of the cost.

Explore the method
  1. Step 01

    Discover

    Map use cases, data estate, infrastructure, and constraints — and establish candidly whether pretraining is the right lever.

    Output

    Readiness assessment

    Learn more
  2. Step 02

    Data Strategy & Curation

    Inventory, redact, deduplicate, quality-score, and mix proprietary corpora into training-grade datasets with full lineage.

    Output

    Versioned training corpus

    Learn more
  3. Step 03

    Pretraining Architecture

    Choose base model, size, tokenizer, and parallelism from scaling-law evidence gathered at small scale.

    Output

    Scaling plan & cost envelope

    Learn more
  4. Step 04

    Training & Evaluation

    Fault-tolerant distributed training with continuous evaluation against harnesses built from real workflows.

    Output

    Evaluated base model

    Learn more
  5. Step 05

    Deployment & Continuous Improvement

    Ship to production, then compound: each cycle reuses what the last one learned to cut cost and raise quality.

Founding partner program

Founding partner program

Shape the practice with us.

We are partnering with a select group of enterprises for our first engagements. Founding partners work directly with our principals, influence what we build next, and receive founding-partner terms.

  • Principal-led engagement from day one
  • Early access to our evaluation and routing tooling
  • A published case study only if and when you choose
Apply to the program

Security & trust

Built for the highest-stakes environments.

Your data never trains our models. Full isolation, audit logs, and private cloud, on-premises, and air-gapped deployment options.

Visit the Trust Center
  • Your data never trains our models

    No client data or derivative is ever used for any other client, product, or model.

  • Full isolation

    Dedicated environments per engagement. No shared clusters, no commingled storage.

  • Audit-ready by default

    Every data access, training job, and artifact transfer is logged and exportable to your SIEM.

  • Deploy anywhere

    Your VPC, dedicated private cloud, on-premises, or fully air-gapped.

Start the conversation

Build the model only your data can build.

Tell us where you are — exploring, piloting, or already training — and we'll show you the fastest credible path to a model you own and an AI bill that shrinks.

We respond within 1 business day. Mutual NDA available before any data discussion.
