Custom AI systems and institutional sites for PE-backed and mid-market companies, delivered end to end by the same person who owns adoption. From $5,000. The portfolio company owns the code.
Why the builds land
A strategy firm writes the plan. A dev shop writes the code. Nobody owns the part where an operating company actually changes how it works. On these builds the same person does the domain work, the software and the rollout.
01
The requirements come from someone who has sat in the seat: three CHRO tours, a JD, and years inside HR, compliance, due diligence and executive operations. No translation loss and no expensive rounds spent teaching the builder your business.
02
Scoping, architecture, build, rollout and training are one accountable line. The system arrives with a named owner inside the portfolio company and a measure of whether people are using it, not just a repository.
03
Full source code, documentation and a recorded handoff, on your infrastructure and your model accounts. No per-seat license, no platform to renew, nothing to lose at the end of the engagement. Vendor lock-in is a failure mode, not a business model.
Delivered projects
Each of these was scoped, architected and shipped for a specific problem in a specific company. Two are proprietary operating systems run in-house and shown as reference architectures a portfolio company can deploy.
Due diligence · PE/VC fund
An AI due-diligence platform for a PE/VC fund investing in defense tech, AI and health tech. Produces structured investment memos with risk scoring, competitive analysis and financial modeling, in the fund's own voice and framework.
Outcome
40 to 60 analyst hours per deal to under 4; deal-evaluation capacity tripled without added headcount.
HR operations · Venture studio portfolio
An HR policy engine built for a venture studio's portfolio companies. Classifies employee tickets, routes them, applies one policy set per operating company and answers from the company's own documents with a citation on every answer.
Outcome
Ticket resolution from 3 days to under 2 hours; ROI positive within 30 days; became a commercial product.
Compliance · I-9 and work authorization
An I-9 and work-authorization compliance auditor. Runs mock audits against current USCIS rules, flags Section 1, 2 and 3 errors and missing or expiring documents, and tracks reverification deadlines across an entire workforce. The compliance logic was written by a 3x CHRO with a JD.
Outcome
Turns I-9 compliance into a standing audit-ready posture across every operating company.
Executive decision system · Proprietary
A decision-integration system: twelve reports in, three decisions out, and an append-only log of every call and the reasoning behind it. Built and run in-house, and deployable inside a portfolio company's executive office.
Outcome
Every decision logged and traceable.
Executive agent system · Proprietary
A 13-node executive agent operating system: twelve functional supervisors plus a chief-of-staff integrator, each gated by a supervisor-swarm-auditor pattern, all producing schema-locked daily reports that roll up into one executive view.
Outcome
Stands up an executive operating cadence in days.
Institutional sites · PE and advisory
Two institutional fund websites for the Ravenbridge platform: the private equity arm investing in critical minerals, data infrastructure and dual-use technology, and the investment banking and advisory arm. One brand system, full thesis architecture, sector pages and investor-relations flows.
Outcome
Delivered at $5,000 per site against agency quotes of $40,000 to $45,000 per site, in three days.
Institutional site · SEC-registered adviser
An institutional redesign for an SEC-registered adviser managing roughly $1.3B across seven niche structured-product verticals, led by former Apollo managing directors. A deep-jade and gold brand system, seven vertical pages, leadership pedigree and a segmented investor contact flow.
Outcome
Rebuilt from a 2016 template into a full brand and thesis architecture.
How it works
01
We define the exact workflow, the data it touches, who uses it and the number that tells us it worked. Most builds are fully scoped in one call. You leave with a spec and a price.
02
Architecture document, model selection rationale, integration map and a signed agreement. Half the fee starts the work. The timeline is locked from here.
03
Weekly demos of working software, not status updates. The feedback loop is short and the build adapts to what your team learns from seeing it run against real work.
04
Full source code, deployment guide and a recorded handoff walking through every component. Balance on delivery. Training for the people who have to use it on Monday. A maintenance retainer is optional.
Pricing
No hourly billing and no scope-creep invoices. The tier is set on the scoping call and the number does not move unless you change the scope.
Focused build
$5,000+
One workflow, one owner, one deployment target.
