AI quant trading systems
Starter through production and flagship Apex Institutional Quant (P13–P15, P17). Engineering deliverables with risk rails, source handoff, and written acceptance — not profit, return, or win-rate guarantees.
Harbor Artificial
Fixed-scope AI, with the price up front.
Two paths, equal weight: AI quant trading systems, and RAG, agents, and ops for product teams. Sticker prices, timelines, and a written definition of done. Not an open retainer, and not a profit guarantee.
Built for founders and product teams who want a finished piece of work — not an open retainer.
Choose a path
Two clear ways in
Equal weight for both lanes. Pick the path that matches the outcome you need — then jump to the package anchors.
Docs, agents, sites & ops
Docs Pilot, Feature Module, Workflow Agent, FAQ bots, landings, checkout, and automations — fixed scope for SMBs and product teams who need a shippable slice.
- Fixed packages
- Written definition of done
- Deposit before build
Composite quotes and portfolio studies on this site are illustrative. They are not attributed client testimonials, logos, or performance claims. Quant work is an engineering handoff only — no profit guarantees.

Product names such as Meridian Apex, Signal Deck, Ledgerly, and Northline Ops are Harbor project codenames for illustrative portfolio studies. Metrics show timeline, scope, and handoff style — not client logos, attributed testimonials, or performance claims. Quant outcomes are engineering handoffs only; no profit, return, or win-rate guarantees.
How we work
Discover · Build · Review
A simple path: align on “done,” build to that list, then accept with a short bugfix. Deposit before we build; change orders in writing.
-
Discover
We align on the outcome, what you’ll provide (docs, APIs, access), constraints, and a short written “done means…” checklist — before any build deposit.
-
Build
We build to that checklist in a fixed window. Longer packages include a mid-build check-in. Anything outside scope gets a written change order with price and timing before extra work starts.
-
Review
You accept against the agreed tests (pass/fail). You get a handoff runbook, plus a 14-day bugfix on what we delivered.
Trust
What working with us feels like
Fixed packages. Written definition of done. Deposit before we build. These launch composites show the kinds of outcomes Harbor is built for. Illustrative voices, not named case studies.
“Honestly we just needed our people to ask questions against our own docs and see where the answer came from. Harbor did that in two weeks for a fixed price. Checklist said done and it was done. No drama.”
“I'm not technical. I am the person stuck in Slack at 4pm because a lead never made it into the CRM. They set up two workflows, error alerts, and a runbook so my team can rerun stuff without texting me. Total lifesaver.”
“Solo. Money is tight. Checkout Kit got Stripe live in a week and I stayed the merchant of record. That mattered more than a pretty page.”
“Eval harness in a week. We stopped shipping prompt tweaks on vibes. Finally.”
“Five pages, real SEO basics, one clear email CTA. No CMS rabbit hole. We launched on the timeline that was on the invoice, which almost never happens with agencies.”
“Offer page Monday. Stripe path by Friday. Launch Stack was the first time shipping the offer did not mean three freelancers and a spreadsheet fight.”
Launch composites for a new studio. Illustrative voices only. Not attributed to named clients.
Written acceptance
Every package ships against a short done means checklist you agree up front. Acceptance is pass/fail on that list, not open-ended polish. You also get a handoff runbook.
Deposits before we build
Work starts after the deposit clears. Most packages are 50/50: final pay when finished, before source handoff. Longer builds like Workflow Agent use a mid-review invoice. Quant packages (P13 through P15 and flagship P17) are 100% upfront at checkout. Blueprint sign-off authorizes build; final pay authorizes code release.
What we don’t take on
Better to know early. We pass on HIPAA or clinical work, regulated finance systems of record, realtime voice products, and open-ended founding-engineer retainers. If that is your need, we will say so plainly and kindly.
