Potomac Falls, Virginia
We build the systems that make AI accountable — and the programs that make it useful.
Gradient Descent LLC is a Virginia technology entity specializing in software architecture, applied machine learning, and enterprise technology risk. We help organizations decide where AI genuinely belongs, deploy it so it makes their people measurably better at the work, and govern it so it can be defended.
We hold the intellectual property behind our products and operate them under dedicated commercial trade names — each built to be run by the organization that owns it, not by us and not indefinitely.

Approach
Fit before force
Not every problem needs a model. The most expensive failures we see are capable systems pointed at the wrong work. We start by deciding what should be automated, what should be augmented, and what should be left alone.
Use-case triage · Feasibility · Right-sizing
Augment, don't replace
The systems worth building make people better at their jobs — faster review, better recall, fewer errors — while a human stays accountable for the decision. That is also what boards, funders, and regulators now expect.
Human-in-the-loop design · Role-based enablement
Governance is the unlock
Organizations rarely stall because the technology failed. They stall because nobody can approve it. Accountability structures are not a brake on adoption — they are what lets a good system actually ship.
Charters · Controls · Evidence
Practice areas
Applied machine learning
Large language models, NLP, transformers, agentic systems, retrieval-augmented generation, and computer vision.
Python · PyTorch · TensorFlow · LangChain · LangGraph
Platform & data architecture
Multi-cloud architecture and migration, data engineering, and analytics platforms at enterprise scale.

NIST SP 800-53 · Okta · Intune · Zscaler
Adoption & human augmentation
Choosing the work AI should touch, designing the human checkpoint, and measuring whether the system actually made people better — not merely busier.
Evaluation design · Workforce enablement · Outcome measurement
