Custom Software Development & Penetration Testing in Raleigh, NC

QUANT LAB USA pairs custom software engineering with hands-on penetration testing rooted in the MITRE ATT&CK framework. We are a Macon, Georgia firm serving Raleigh and the broader Triangle remote-first across the same Eastern Time zone, with travel into Wake and Durham counties for major builds and on-site network work. Triangle operators typically need the same things: multi-tenant SaaS that scales cleanly, Stripe-grade billing, and a pen test report that unblocks enterprise procurement and SOC 2.

The Triangle's software demand is concentrated and sophisticated. Research Triangle Park — the largest research park in the country — anchors a life-sciences and technology base that includes biotech, pharma, and analytics operators, while downtown Raleigh and Durham have grown a deep startup scene around the universities. SAS in Cary set the template for software in the region decades ago, and the venture and accelerator ecosystem since then has produced a steady flow of growth-stage SaaS. North Carolina State's Centennial Campus, Duke, and UNC keep the talent pipeline full. The common thread is that these companies sell to enterprise buyers who demand SOC 2, clean multi-tenant architecture, and security that holds up under a customer's due-diligence review.

Most Triangle shops are either large consultancies or staff-augmentation bodies. We sit in the middle: founder-led delivery with enterprise-grade engineering practices and in-house offensive security. No offshore handoff and no junior outsourcing — William Beltz scopes, builds, and ships. That matters when a growth-stage SaaS needs both a clean codebase and a pen test report that closes an enterprise deal, or when a biotech operator needs tooling that respects data-integrity expectations.

Triangle founders are technical and will not tolerate a sales team that hands the work to juniors. Our model removes that risk: every engagement is scoped, built, and shipped by the founder, on a fixed-scope and fixed-price proposal with a written acceptance milestone — not open-ended time-and-materials billing. Our pen testing is in-house capability, not a subcontracted line item: Active Directory abuse paths, lateral movement, web application exploitation, and wireless attacks, with every finding mapped to a MITRE ATT&CK technique ID. And every line of software we ship is reviewed against the same threat models we use on offensive engagements.

We run full Eastern Time overlap from Macon, which keeps standups and reviews on the Triangle's clock. Most kickoffs are a video call followed by a single on-site afternoon — typically in downtown Raleigh, Durham, Cary, or Morrisville — to walk the workflow we are replacing. From there, build cycles run weekly: every Friday you get a deployed staging URL, written notes on what changed, and the next-week plan. Pen testing engagements run from secure remote infrastructure with strict source-IP allowlisting and authenticated VPN tunnels for internal scope, and we travel to the Triangle for sensitive scoping and for internal tests requiring on-site network access. Reports ship in two formats: a technical deliverable with reproduction steps for the security team, and a board-readable executive summary with a prioritized remediation roadmap. Most Raleigh engagements close inside 4–6 weeks from kickoff to final report.
