Burt

Using AI?

Helps AI teams train and deploy specialized models that are 10x faster and cheaper than frontier.

Using fine-tuning infrastructure for domain-specific models, optimized low-latency deployment, and continuous improvement loops that beat generalist alternatives.

Company Overview

Helps teams train and deploy specialized AI models that outperform general, closed-source alternatives while being 10x faster and cheaper. Targets teams building AI agents where LLM calls are too slow, too expensive, or not reliable enough.

Product Roadmap & Public Announcements

Burt has launched its platform for training and deploying specialized models. Per YC, they target teams where LLM calls are 'too slow, too expensive, or just not good enough.' The platform helps move from general closed-source models to specialized alternatives that are 10x faster and cheaper.

Signals & Private Analysis

Both founders previously worked at Replo (YC S21), giving them strong YC network access. Bobby also has experience at Pirros (YC W23). The model fine-tuning and deployment market is growing rapidly as companies shift from prototyping with frontier models to production with specialized ones.

Machine Learning Use Cases

Real-Time Event Tracking
For
Operational Efficiency
Operations

<p>AI-powered autonomous shipment tracking and proactive exception alerting across carriers and systems.</p>

Layman's Explanation

An AI agent watches every shipment like a hawk, automatically chasing updates from carriers and alerting your team only when something actually goes wrong.

Use Case Details

Burt deploys an AI agent that continuously monitors shipment status across multiple carrier APIs, TMS platforms, and email inboxes using retrieval-augmented generation (RAG) to pull real-time data and LLM-based reasoning to interpret unstructured updates (e.g., carrier emails, EDI messages). The agent identifies exceptions—late pickups, missed scans, weather delays—and proactively escalates them to the appropriate human operator with context-rich summaries and suggested next actions. This eliminates the need for operations teams to manually check dozens of carrier portals and parse hundreds of daily status emails, dramatically reducing response times and preventing costly delivery failures before they cascade.

Analogy

It's like having a tireless intern who refreshes every carrier tracking page every five minutes, reads every email, and only taps you on the shoulder when the building is actually on fire.

Document Intelligence & Risk
For
Risk Reduction
Operations

<p>Automated carrier vetting and compliance verification using AI-driven document analysis and risk scoring.</p>

Layman's Explanation

An AI agent reads, verifies, and scores every carrier's insurance, authority, and safety documents so your team doesn't have to play detective with PDFs.

Use Case Details

Burt's carrier vetting agent ingests carrier onboarding documents—certificates of insurance, FMCSA authority records, safety ratings, and broker-carrier agreements—and uses LLM-powered document understanding to extract key fields, cross-reference them against authoritative databases (FMCSA SAFER, insurance verification APIs), and generate a composite risk score. The agent flags discrepancies (e.g., lapsed insurance, authority revocations, poor safety scores) and either auto-approves low-risk carriers or routes edge cases to a human reviewer with a detailed risk summary. This transforms a traditionally manual, error-prone, and time-consuming process into a fast, consistent, and auditable workflow—critical for brokerages and 3PLs managing hundreds or thousands of carrier relationships.

Analogy

It's like a bouncer at a nightclub who instantly checks every ID, calls the DMV to verify it's real, and only bothers the manager when someone shows up with a fake mustache.

Multi-Constraint Optimization
For
Revenue Growth
Strategy

<p>Intelligent load building and quoting optimization using multi-agent reasoning over capacity, cost, and constraint data.</p>

Layman's Explanation

An AI agent figures out the best way to fill a truck and price a load by juggling dozens of constraints at once—faster and more accurately than a human planner.

Use Case Details

Burt's load building agent uses a multi-agent architecture where specialized sub-agents handle distinct aspects of the problem: one retrieves real-time capacity and equipment availability from TMS and carrier systems, another analyzes historical lane pricing and market rate data, and a third evaluates physical constraints (weight limits, dimensional compatibility, hazmat restrictions, delivery windows). An orchestrating LLM synthesizes these inputs to recommend optimal load configurations and generate competitive quotes. The system learns from accepted and rejected quotes over time, fine-tuning its pricing models and constraint weighting. This replaces the traditional process where experienced planners manually juggle spreadsheets, rate sheets, and phone calls—unlocking faster quote turnaround, higher load utilization, and better margin capture, especially for mid-market brokerages that lack dedicated pricing analytics teams.

Analogy

It's like a Tetris grandmaster who also happens to be an economist—fitting every box perfectly while making sure you're not leaving money on the table.
