Custom Software Development & Penetration Testing in Denver, CO
The Front Range is one of the most distinctive tech economies in the country — a national center for the space industry, the birthplace of the legal cannabis market, and a magnet for fintech and SaaS startups. Each of these demands software vendors who understand both engineering and security.
QUANT LAB USA combines custom software engineering with hands-on penetration testing rooted in the MITRE ATT&CK framework — not just selling development hours. Denver buyers, from space-supply-chain operators to compliance-bound cannabis operators to SaaS founders, expect a vendor who can build a production system and break it like an attacker. We do both in-house.
Why Denver organizations choose QUANT LAB USA
Denver and the broader Front Range have one of the most diverse tech economies in the West. The region is a national hub for the space industry — Lockheed Martin Space in Littleton, Ball Aerospace in Boulder, Sierra Space, United Launch Alliance, and a constellation of suppliers feed a sector reinforced by Buckley Space Force Base and Schriever down in Colorado Springs. Colorado pioneered the legal cannabis market, and a whole category of compliance-bound seed-to-sale and operations software grew up around it. Downtown Denver, the RiNo district, and Boulder host a dense fintech and SaaS startup scene, while energy, telecom, and a deep healthcare base around the Anschutz Medical Campus in Aurora round out the economy. The University of Colorado and the Colorado School of Mines keep the engineering talent pipeline full.
Most generalist agencies cannot credibly speak to penetration testing methodology, and most security shops cannot ship production software. We do both. Active Directory abuse paths, lateral movement, ADCS certificate abuse, Kerberoasting, and web app exploitation are in-house capability, not a subcontracted line item — and every line of software we ship is reviewed against the same threat models we use on offensive engagements. For Front Range companies in regulated markets or chasing SOC 2 and enterprise security reviews, that combination is the entire pitch.

Proof of work
Our pen testing track record includes a full Active Directory engagement for a regional financial services firm — an end-to-end internal assessment running eleven attack modules, every finding mapped to a MITRE ATT&CK technique, with the full attack chain from standard user to Domain Admin documented in screenshots and timestamps. The client passed their compliance audit on the first attempt and re-engaged us on a six-month cadence. That is the same methodology we apply to every Denver engagement, whether the buyer is a space supplier, a cannabis-tech operator, or a SaaS company prepping for SOC 2.
QUANT LAB USA is founder-led and accountable end-to-end. We ship production web and SaaS applications on a modern Next.js, TypeScript, PostgreSQL, and Docker stack, and we keep our proof generic with references available under NDA — we do not name-drop clients who did not sign up to be a marketing line.

How we work remotely with Denver teams
Denver runs on Mountain Time, two hours behind Georgia HQ, so our early afternoon and your late morning overlap cleanly for standups and design reviews. Most engagements start with a 60-minute scope by video, followed by a fly-in for an on-site kickoff afternoon — downtown Denver, RiNo, the Tech Center, Boulder, or Colorado Springs. After kickoff, build cycles run weekly with a Friday staging URL, written notes, and the next-week plan. Internal pen tests requiring on-site network access are scheduled on-site for the active window with remote reporting following. We bill fixed scope on virtually every Denver engagement, and code, database, hosting accounts, and full documentation transfer at acceptance — exactly what procurement needs for ownership and audit review.
FAQ
Do you work with aerospace and space companies?
Yes — supplier portals, compliance tracking, and ITAR-aware workflows are in scope for the Lockheed Martin Space, Ball Aerospace, Sierra Space, and broader Front Range space ecosystem. Cleared environments are scoped case-by-case, and clearance status is discussed under NDA.
Can you build compliant cannabis-tech and seed-to-sale software?
Yes — compliance-aware inventory, Metrc state-tracking integration, and operations dashboards for licensed operators in Colorado's regulated market. We scope state-reporting and audit requirements up front rather than bolting them on later.
Do you work with Denver fintech and SaaS startups?
Yes — multi-tenant architecture, payment integrations, onboarding flows, and Stripe billing are core work for us, well-suited to the startup corridor in RiNo, downtown Denver, and Boulder.
Do you do web application penetration testing?
Yes — OWASP-aligned testing for SaaS products, fintech apps, and customer portals. Every finding is mapped to a MITRE ATT&CK technique and delivered with reproduction steps and a remediation roadmap.
Can you help us prep for a SOC 2 audit?
Yes — pre-audit penetration testing that maps cleanly to SOC 2 CC controls, with reports formatted to drop into your audit binder. This is routine for Front Range SaaS companies pursuing enterprise deals.
Can you fly in for kickoffs along the Front Range?
Yes — for engagements above roughly $25k we fly into DEN for an on-site kickoff afternoon. Downtown Denver, RiNo, the Tech Center, Boulder, and Colorado Springs are all reachable, and on-site internal testing is scheduled for the active window.
How does the time zone work with your Georgia HQ?
Denver is on Mountain Time, two hours behind Georgia HQ. Our early afternoon and your late morning overlap cleanly for standups and design reviews, and we plan async handoffs around the window.
What is a typical timeline for a Denver engagement?
A standalone web app pen test runs 2–3 weeks including reporting. A meaningful custom build typically runs 4–6 months, with a staging URL shipped weekly during development.
