You've seen the prototype. The board is excited. But months later, the model is still in a notebook — and your team is drowning in edge cases, compliance questions, and infrastructure decisions they weren't hired to solve.

What We Build

End-to-end AI development,
from thesis to production.

We don't hand you a strategy deck. We ship working systems — designed for the humans who use them.

🚀

AI Application Development

Custom AI applications — from LLM-powered workflows to computer vision pipelines. Architecture through deployment, shipped in weeks.

🤝

Human-in-the-Loop Design

Workflows that keep humans in supervisory roles. Powered by PropelTeam, our HITL platform battle-tested across dozens of deployments.

🗺️

AI Strategy & Architecture

We map your AI opportunity space, evaluate build-vs-buy decisions, and design system architectures that scale. Walk away with a blueprint.

🏗️

Startup Studio

We co-build AI-native startups from scratch. Bring a thesis or a domain — we bring engineering, design, product strategy, and capital.

⚙️

AI Ops & Managed Services

Post-launch model monitoring, drift detection, retraining pipelines, and continuous HITL optimization. Your AI improves after day one.

Rapid Prototyping Sprints

Six-week engagements to validate an AI concept with a working prototype. Test feasibility and make go/no-go decisions with real data.

Our Work

Proof in production.

Selected engagements where we built AI systems that shipped, scaled, and delivered measurable impact.

Healthcare Operations

AI Scheduling Agent for Thousands of In-Home Patient Visits

A national home healthcare provider needed to optimize scheduling across thousands of daily visits. Manual dispatching left 30%+ shifts unfilled. We built an AI agent with PropelTeam human oversight that handles complex constraint satisfaction at scale.

AI Voice Agent That Answers Every Call in Under 34 Seconds

A high-volume services company was losing leads to voicemail — 40% of calls going unanswered. We deployed an AI voice agent that answers instantly, qualifies leads naturally, books appointments, and escalates complex inquiries to humans via PropelTeam.

Developer Tooling

AI Coding Agent That Increased Commit Velocity by 20×

An engineering team was bottlenecked by boilerplate, tests, and migration scripts. We built a custom AI coding agent integrated into their CI/CD pipeline with human code review via PropelTeam. Developers describe intent; the agent writes, tests, and submits PRs.

Our Process

From conversation to
production in three phases.

Every engagement follows a structured, transparent process. You see working software every sprint.

1

Discover & Define

We dive deep into your domain, users, and constraints. In two weeks you have a technical architecture and clear success metrics.

2

Build & Iterate

Weekly sprint demos with working software. Human-in-the-loop workflows are designed and tested with real users from day one.

3

Deploy & Optimize

Production deployment with monitoring, alerting, and retraining pipelines built in. We stay to measure impact and improve.

Powered by PropelTeam

Human-in-the-loop,
solved.

Every engagement is powered by PropelTeam — our proprietary platform for building, managing, and optimizing human-in-the-loop AI workflows.

Review queues that surface the right tasks to the right humans at the right time, with configurable escalation.

Confidence scoring that routes low-confidence outputs to reviewers automatically — zero manual triage.

Audit trails for every decision, override, and approval. Built for compliance from the ground up.

Continuous learning that feeds human corrections back into retraining, making your AI smarter over time.

What Clients Say

Trusted by founders who can't
afford to get AI wrong.

"We tried building AI in-house for six months. Propel shipped in eight weeks what our team couldn't crack — with better architecture than we would have designed ourselves."
MK
Marcus Kim
CTO, Series B Healthtech
"They didn't just build our AI — they taught our team how to think about human-in-the-loop systems. The PropelTeam integration was a game-changer we didn't know we needed."

FAQ

Common questions.

Two things. First, we ship production code — not strategy decks. Every engagement ends with working software. Second, PropelTeam is our proprietary human-in-the-loop platform that powers every project. We've already solved the hardest part of making AI work reliably with human oversight.
They will, eventually. Our advantage is speed, specialization, and institutional knowledge. By the time a large firm stands up an HITL practice, we'll have 100+ production deployments of expertise baked into PropelTeam. Big firms are generalists — we're specialists with proprietary tooling.
Both. For funded startups (Seed through Series C), we offer project-based engagements. For pre-seed teams with compelling ideas, our Studio arm co-builds AI startups for equity partnerships. The Sprint at $75K is designed for validation-stage work.
Your AI system has built-in checkpoints where humans review, validate, or approve outputs before they reach end users. Low-confidence predictions go to expert reviewers, every decision has an audit trail, and corrections automatically improve the model. PropelTeam handles all the orchestration.
Typically 2-3 weeks from signed agreement. We run a free 60-minute strategy session first, draft an SOW within a week, and intentionally cap active engagements to ensure senior engineers do the work.
You own everything — code, models, infrastructure, PropelTeam configurations. We provide documentation and knowledge transfer. Many clients continue with a retainer ($15K–$50K/month) for ongoing AI ops, but it's optional.

Let's build what's next.

Limited availability — we cap engagements to keep quality high.
