Design, implement, and optimize LLM-powered models for document processing, data extraction, and permit application workflows
Develop and fine-tune retrieval-augmented generation (RAG) pipelines to improve query processing and information retrieval
Experiment with pre-trained models and fine-tune them for permit-related NLP tasks, such as document classification and entity recognition
Build scalable machine learning infrastructure, integrating with backend systems to support AI-driven workflows
Work with large-scale structured and unstructured data to ensure efficient indexing, retrieval, and contextual relevance
Monitor and improve the performance and scalability of deployed models
Stay updated with the latest research in LLMs, NLP, retrieval systems, and apply best practices to our AI models
Collaborate with engineers, product managers, and legal experts to develop AI-native solutions for complex permitting challenges

Our take

Aiming to release value in the construction market, PermitFlow is an AI-powered construction permit application and management platform. It exists to simplify the pre-construction process for builders and owners, enabling them to move forward with projects more easily.

The company offers a standardized permit application workflow through which users can easily prepare and submit permit applications, receive approvals, and respond to municipal comments on one single platform. This saves time, reduces errors and shortens municipal review cycles, ultimately speeding up the time taken to permit.

Through the deployment of advanced technologies, PermitFlow has kept up with the needs of a changing market, benefitting builders and stakeholders across the nation. As AI has advanced, so too have the company's algorithms, bringing in new functionalities such as voice AI agents that can schedule an inspection as soon as a project is permitted.
