They do not market off-the-shelf consumer products; they develop custom, mission-focused solutions: - **Signal Processing Solutions**: Combining traditional signal processing with machine learning algorithms to process gigasamples of data at the edge and in the cloud. - **Computer Vision Solutions**: Detecting and tracking real-world objects across multiple sensing modalities, capable of performing with scarce training data. - **Deep Learning Solutions**: Researching and deploying novel neural networks for real-time, raw sensor data challenges. - **Embedded Systems Solutions**: Implementing FPGA and GPU subsystems for image and signal data classification. - **Web / Cloud / DevOps**: Building robust, secure solutions using Docker, Kubernetes, and CloudFormation with a focus on CI/CD and automation. ## Market Standing - **Valuation**: Not publicly available (private, non-VC-backed entity). - **Key Metric**: Over a decade of sustained operations (founded 2013) with a strong reputation in the defense tech sector. - **Notable Clients/Partners**: U.S. Department of Defense, Intelligence Community (IC), and prime defense contractors. The company’s work is classified and unclassified. - **Growth Signals**: Active hiring in multiple technical areas (Computer Vision, Deep Learning, Embedded Systems, Cloud) indicates consistent demand and growth. The company states their skills are “in high demand.” ## Competitive Advantages - **Deep Domain Expertise**: Specialized in a highly technical intersection of AI/ML, signal processing, and national security, creating a high barrier to entry. - **Research-Driven Culture**: Actively performs applied research to advance the state of the art, differentiating them from pure implementation contractors. - **Unique Organizational Model**: Operates as a “team of teams” using coaches instead of traditional managers, designed to foster autonomy, continuous learning, and rapid reconfiguration for specific project goals. - **Product-Oriented Mindset**: Unlike many government-services firms, EXP focuses on seeing ideas through to actualized, deployable products. ## Strategic Focus - **Continuous Research & Innovation**: Keeping pace with and pushing the boundaries of AI/ML, sensor processing, and edge computing to solve urgent national security problems. - **Talent Retention & Development**: Investing heavily in a unique coaching and benefits model to attract and keep top-tier technical talent in a competitive defense-tech labor market. - **Agile, Client-Centric Delivery**: Maintaining flexibility in project planning to meet specific, unique mission requirements of the DoD and IC. ## Why Work Here - **Unique Management Structure**: Replaces traditional “bosses” with “coaches” who advocate for career progression and connect employees to learning opportunities. Employees choose their own coach annually. - **Exceptional Benefits & Flexibility**: - **Individual Benefit Account (IBA)**: Employees receive a pool of funds to allocate as they wish across healthcare, PTO, and a bonus. Unused IBA dollars are paid out at year-end. - **Flexible Cash PTO**: Can take up to 45 days of PTO per calendar year and can cash out unused time. - **Retirement**: Up to 12% contribution to a 401(k) (employer match/profit sharing) plus student loan repayment plans. - **Parental Leave**: 12 weeks paid for primary caregivers; 2 weeks for secondary. - **Learning Culture**: Autonomy to guide careers with support from coaches. Benefits include tuition assistance, conference attendance, and internal “brown bag” discussions. - **Mission-Driven Work**: The opportunity to work on cutting-edge technology that directly impacts national security. - **Work Policy**: Likely on-site or hybrid, given the classified nature of much of the work (Herndon, VA location). - **Commitment to Accessibility**: Explicit accommodations policy for candidates with disabilities. ## Sources 1.
