Fractional CTO & CIO
Fractional CTO-level guidance for founders, managing partners, and executives on strategy, hiring, vendor negotiation, and a defensible roadmap.
Systems Architecture
Design, deploy, and configure the platforms your operation depends on: identity, case management, cloud tenants, endpoint policy, wired together cleanly and securely.
Automation & Integration
Replace manual handoffs with reliable, observable automations and integrations across the platforms your team already uses.
AI Solutions
Practical AI deployments across drafting, intake, call handling, analysis, and internal policy, that pay for themselves and pass a partner-level review.
Cybersecurity
Protect the firm without grinding it to a halt. Identity hardening, endpoint policy, incident response, and vendor risk, in that order.
Compliance & Delivery
Implementations and migrations delivered on schedule, with the change management, training, and compliance work that makes the new system stick.
Who we serve
Built for the modern firm, and for the brands people love.
The practices are the same across every client; the platforms and the pressures change. Start with your world.
The approach
Compassionate. Intuitive. Tenacious.
We listen first. We map the work. Then we design technology solutions that are easy to ship, measure, and refine. Whether it's a single integration or a firm-wide platform migration, the goal is the same: technology that earns its keep.
