LANE 01 · AGENTS FOR YOUR AI SDLC
Engineering chores, running unattended: release notes, code review, spec generation.
- Code Review & Release Notes Agents
- Spec Generation Agents
CUSTOM AI AGENT DEVELOPMENT SERVICES
Custom AI agents that survive contact with production.
We design, pilot, and harden agentic systems on your existing platform, beside the team that owns it: data foundation first, human-in-the-loop always. Regulated or not, “the model said so” never passes our gates. First agent scoped in 2 weeks.
Get expert help with your AI agent project.
CUSTOM AI AGENT
Built on your data foundation, wired into your platform. Human sign-off before production.
CUSTOM AI AGENT DEVELOPMENT SERVICES
Custom AI agents for your AI SDLC, your product, your operations.
Agent projects fail at the data stage more often than the model stage. Three lanes, one build system: agents for engineering, agents inside your product, agents for the business. Applied AI engineering, end to end.
LANE 02 · PRODUCT & PLATFORM FEATURES
Intelligent features inside the product you sell: the agents your customers pay for.
- Platform Copilots (In-Product)
- RAG & Retrieval Systems
- Custom AI Agent Development
LANE 03 · BUSINESS PROCESS AUTOMATION
Back-office throughput without back-office headcount: finance, operations, procurement.
- Workflow Automation Agents (Finance, Operations, Procurement)
- Data Foundation & Readiness
Every lane ships on the same platform layer
Prompt management · Agent monitoring & observability · AI governance & compliance · Cost controls & safety rails
Agent evals and monitoring, human-in-the-loop governance, and production hardening with cost control come standard on every build. The governance layer is documented on our AI governance page (coming soon).
CASE STUDIES
Documented results from embedded delivery.
Uplift measured against each client’s own baseline on our Dev Intelligence Platform. Not industry averages.
B2B PLATFORM · PE-BACKED · NDA
Production agents customers pay for
Data-exhaust extraction first, then agents embedded into the platform itself with human-in-the-loop checkpoints and full audit logging. Real production agents inside the product, not a demo reel.
- Production agents
- Data foundation
- Audit logging
HEALTHTECH · HEALTHCARE PRIOR-AUTH
3-4x operator throughput target, human-in-the-loop
Agents replacing brittle scripted bots: automating where confidence is high, handing off where it isn’t. Target agreed with the investors. First analyst working within days of signature.
- HITL agents
- Regulated
- Named reference

ENGAGEMENT MODELS
Plug us in where you need us most.
ONE POD PLUGS IN. THEN IT COMPOUNDS.
EMBEDDED ENGINEERS
Extra seniority inside your team
Our engineers join your standups, your repos, your rituals. You lead, they deliver, and they act like teammates because that’s what they are.
DEDICATED PODS
A delivery unit with its own engine.
A pod plus structured PM oversight drives a workstream end to end. Cadence, backlog, and risk visibility stay on your dashboards.
FULL OWNERSHIP
You define outcomes. We own
execution.
Hand off the full lifecycle from planning to production. You stay looped in at every gate, without running the machine.
THE PROCESS
How an AI agent gets to production.
Prototype it, then make it real. Three phases, in that order, every time.
-
We scope it: readiness, data, guardrails
Two weeks on your data and platform. Architecture decision document, data foundation plan, and guardrail design before any agent gets built.
-
We build it with you watching: pilot, evals, sign-off
A pilot agent on one real workflow, an eval harness that scores it, and a human sign-off gate. You see every run. Prototype first, then decide.
-
We make it real: harden and scale
Production hardening, cost controls, monitoring, and rollout across teams. The full 8-step engineering detail behind these phases is yours in the first call.
INDUSTRIES
Regulated or not, we’ve shipped in your world.
Healthcare, insurance, mortgage & lending, and legal are where we go deepest. Financial services and enterprise SaaS round out the bench. We arrive knowing your constraints, not discovering them on your dime.

FOR PRIVATE EQUITY
Value creation projects, not science projects.
More than half our business is PE-driven. We build agents that move the operating metrics the deal team already tracks.
OPERATING LEVERAGE
Throughput without headcount.
Finance, operations, and procurement workflows automated with human oversight. Output scales; the org chart doesn’t.
BOARD-READABLE
Every agent measured and attributable.
Usage, cost, and outcomes tracked on the Dev Intelligence Platform with an immutable audit trail the sponsor can read.
PORTFOLIO-REPEATABLE
One portco’s agent becomes a playbook.
What ships in one company travels across the fund: same guardrails, same evals, faster every time.
FAQ
What tech leaders ask us.
Typical path: 2-week readiness audit, pilot live by week 6, production hardening from week 7. Regulated environments can add time, and we tell you where.
