From the Architect of Cumulative Computing

Cumulative
Intelligence.

SDK Tech LLC commercializes the Cumulative Computing paradigm — building agents that learn, retain, and scale across regulated capital markets data corridors.

The Core Thesis

Persistent Agentic Memory.

"Computing is no longer about the processing of instructions, but the accumulation of contextual intelligence."

Our Founder is the primary researcher behind CumulativeComputing.org. We are leading the industry shift from stateless AI to systems that possess a persistent, evolving understanding of complex data ecosystems — industrializing non-volatile agentic memory for enterprise capital markets.

Banking Business Process — Enterprise Grade

Agentic BPO
with Full Provenance.

Broker Pricing Opinions generated by autonomous agents — each one backed by a complete, auditable reasoning chain that satisfies OCC, Fannie Mae, and Freddie Mac collateral standards.

"Provenance is the ultimate currency of AI."

— Richard Kopcho

OCC Collateral Standards Fannie Mae Guidelines Freddie Mac Requirements GSE Submission Ready Full Audit Trail

The Provenance Chain — Every BPO, Every Step

Licensed MLS

Source of record — institutional ground truth

Vertex AI Search

Semantic comparable selection at scale

Agentic Reasoning

Cumulative memory — every decision logged

Regulatory Output

BPO formatted for GSE submission

Immutable Audit

Zero-trust storage — SDK Secure EOOD

Every BPO produced on the .re Corridor carries a complete, step-by-step provenance record — from the licensed MLS comparable selected, through the semantic reasoning logic applied, to the final value opinion delivered. Regulators, examiners, and GSE counterparties can interrogate every decision node in the chain. No black boxes. No inference gaps. Cumulative memory means the agent's reasoning chain is the audit trail.

OCC — 12 CFR Part 34

Office of the Comptroller

Agentic BPOs satisfy OCC real estate appraisal standards through documented source data, traceable comparable methodology, and explainable value derivation — ready for examination-level collateral review.

Fannie Mae / Freddie Mac

GSE Collateral Standards

BPO outputs are structured for GSE submission workflows, with licensed MLS as the authoritative data source — aligning with Fannie and Freddie collateral assessment frameworks for loss mitigation and REO disposition.

Provenance by Design

Cumulative Audit Trail

The Cumulative Computing memory layer doesn't just process — it records. Every agentic decision is logged, versioned, and retrievable. Persistent intelligence that builds a regulatory-grade audit record as a natural byproduct of reasoning.

Agentic Grid — Grid Node 01

The .re Corridor

A 335-node national agentic grid for real estate capital markets — piloting in Colorado, expanding with every area code.

Live Pilot

970.re

Northern Colorado

Fort Collins · Grand Junction · Steamboat Springs — licensed MLS data grounding agentic real estate reasoning in institutional truth.

303
Next Deployment

303.re

Denver Metro

Colorado's largest market. High-velocity transaction volume makes this the critical validation and scale node.

Southern Colorado

Colorado Springs · Pueblo — completing statewide grid coverage before national rollout begins.

Google Vertex AI Search Integration Roadmap

Architected for Google Vertex AI Search

Current MLS semantic retrieval fails on address variants, lot-size tolerances, and multi-field property queries — the inherent limitations of hybrid BM25/embedding pipelines. The .re Corridor is purpose-built for Vertex AI Search's grounded semantic retrieval, replacing brittle keyword matching with contextually intelligent, MLS-native query understanding at 335-node institutional scale.

Grid Node 02 — Agentic Terminal

MyWinnow

The definitive agentic data reconciliation terminal.

MyWinnow utilizes semantic matching logic to perform high-scale data hygiene across distributed enterprise file systems — deduplicating and organizing data across local, external, and cloud storage with deterministic precision.

Technical Architecture

The Cumulative Stack

Layer 01 — Memory

Cumulative Computing

Non-volatile agentic memory built on the CumulativeComputing.org framework. Agents accumulate verified intelligence — and produce a regulatory-grade audit trail as a natural byproduct of every reasoning step.

Layer 02 — Search

Vertex AI Search

Grounded semantic retrieval across licensed MLS data corridors. Intent-aware, domain-native understanding — the backbone of defensible BPO comparable selection at institutional scale.

Google Cloud — Integration Roadmap

Layer 03 — Security

SDK Secure EOOD

EU-based R&D through our Sofia, Bulgaria entity. Zero-trust encapsulation for banking-grade data flows — every provenance record immutably stored and examination-ready at every grid node.
