Software built fast. AI trained right.
LatencyX is two things under one roof: a senior engineering team that ships MVPs and production software for founders, and a human evaluation team that trains, tests, and aligns AI models for labs and product teams.
PergoRides
MVP & product engineering
For founders and product teams who need real software designed, built, and maintained by senior engineers.
More about MVP development
MVP Development
Transform your idea into a scalable, investor-ready product. We handle rapid development, strategic planning, and market-focused execution so you can validate demand before you overbuild.
Web & Frontend Development
Fast, accessible, well-structured web applications and interfaces, built with modern frameworks and engineered to hold up as your product and traffic grow.
Website Redesign
A full rebuild of an existing site's design, structure, and performance — without losing the SEO equity and content your business already earned.
UX/UI & Product Design
Research-led interface design. We test with real users, then design flows that are easy to use, consistent to navigate, and built to convert.
AI Systems & Automation
Production-ready AI features and agents that automate real workflows — support, research, data entry, internal tooling — with the reliability a live business needs.
Maintenance & Support
Ongoing monitoring, updates, and fixes after launch, so the product you shipped keeps working as dependencies, traffic, and requirements change.
AI training & model evaluation
We help improve AI systems through high-quality human feedback, data evaluation, and model testing — reviewing outputs for accuracy, relevance, reasoning, safety, and overall quality.
More about AI evaluation services
AI Model Evaluation
We review and compare AI-generated responses for accuracy, reasoning, relevance, instruction-following, and overall quality.
AI Training Data & Annotation

Human Feedback & RLHF
Structured human feedback, response ranking, and preference evaluation to support reinforcement learning and model alignment.
Prompt & Response Testing
We test prompts and model responses to identify incorrect answers, hallucinations, reasoning issues, and opportunities for improvement.
AI Quality Assurance
Detailed review of AI-generated content and annotated datasets to ensure consistency, accuracy, and compliance with project requirements.
Technical AI Evaluation
Coding, software engineering, and technical-reasoning responses evaluated by experienced technical reviewers who understand the work being judged.
AI Safety & Alignment
We review AI outputs against defined safety, quality, and behavioral guidelines to help build more responsible and dependable AI systems.

How an engagement runs
The same four stages apply whether you're shipping a product or handing us a model to evaluate.
Discover
We scope the problem, the constraints, and what “done” actually looks like before any work starts.
Build
Engineers or reviewers get to work in short, visible cycles — you see progress, not a black box.
Evaluate & test
Every output is reviewed against agreed criteria — functional QA for software, human review for model outputs.
Launch & support
We ship, hand off documentation, and stay on for maintenance or ongoing evaluation as needed.
What founders say
Three MVP engagements, in the clients' own words.
LatencyX delivered our investor-ready MVP in just 10 weeks. Their structured execution framework eliminated the chaos we'd experienced with freelancers. We went from concept to live product with clear ownership and zero technical debt.
Lana IsraelFounder, MuzologyAs a non-technical founder, I needed a team that could execute without constant hand-holding. LatencyX's predictable process and clear communication meant I could focus on fundraising while they built a production-grade MVP that investors actually wanted to see.
Duncan RayFounder, SummerDazeWe had seed funding but no technical co-founder. Hiring would've taken 6+ months. LatencyX got us to market in 8 weeks with a scalable architecture. The MVP wasn't just functional — it was investor-ready and ready to scale from day one.
