FAQs
What does a software development company in the USA do?
A software development company in the USA designs, builds, tests, and maintains software for businesses operating in or serving the American market, including custom applications, web and mobile apps, SaaS platforms, and AI solutions. Saigon Technology delivers full-lifecycle development from our Reston, Virginia office.
What are the benefits of custom software development for US businesses?
Off-the-shelf tools fit the average business. Custom software fits yours. Here is what US teams gain by building:
Lower total cost of ownership. Replace stacked per-seat SaaS fees with software you own outright.
Compliance fit by design. HIPAA, SOC 2, PCI-DSS, and GDPR controls built in, not bolted on.
Faster time-to-market. A working MVP in 2 weeks to 4 months, then releases every few weeks.
Architecture that scales. Cloud-native from day one, deployed to the same AWS regions that power Northern Virginia.
Full IP ownership. Your source code, your contracts, US-jurisdiction NDAs.
AI-native productivity. Senior engineers plus AI tooling deliver more, with less rework.
Where is Saigon Technology located in the US?
Our US office is Saigon Technology USA Inc., 12110 Sunset Hills Rd, Ste 600, Reston, VA 20190. From Virginia we serve clients nationwide, supported by three ISO-certified engineering centers.
Why hire Saigon Technology over a purely US-based software development company?
You get the same - or higher - engineering quality at a fraction of the cost. Senior engineers paired with AI produce the output of larger junior teams, while a software development company in Virginia presence, fluent English, and US time-zone overlap keep collaboration as smooth as an onshore engagement.
US in-house vs. Saigon Technology: what does it really cost?
The cost gap between hiring in-house in the US and partnering with Saigon Technology is substantial at every level. A senior developer typically runs $120 to $200+ per hour fully loaded with a US in-house team, whereas Saigon Technology delivers the same seniority for $40 to $70 per hour. The pattern holds at the team level too: a blended team rate that lands between $100 and $175 per hour in-house comes in at just $28 to $46 per hour with Saigon Technology.
Beyond cost, the difference shows up in speed and risk. Standing up an in-house team means weeks to months of hiring before you see a first approved CV, while Saigon Technology can put a qualified candidate in front of you within days. And where an in-house hire offers no built-in safety net, Saigon Technology backs the engagement with a 2-week risk-free trial.
How we run our projects: what project management practices do we use?
Predictable delivery is the difference between a vendor and a partner. Our project management practices are built for fact-based decision-making and full transparency:
- Methodologies: Scrum with 2-3 week sprints, Kanban for support and evolution, and Agile development end to end.
- Cost estimation: transparent, feature-level estimates with no surprise billing.
- Risk management and change management: structured processes to catch issues early and absorb scope changes.
- Quality management system: a shift-left approach to QA, code reviews, test automation tools, and a clear "definition of done."
- Success measurement: KPIs, weekly report examples, and joint reviews to keep cooperation healthy.
Do you support HIPAA, SOC 2, and PCI-DSS compliance?
Yes. We build to HIPAA for healthcare, PCI-DSS and KYC/AML for fintech, and SOC 2-aligned controls, under an ISO 27001-certified security management system with audit trails and role-based access.
Which engagement model is best for US startups vs. enterprises?
- Startups: Staff Augmentation or Fixed-Price to validate fast and control budget.
- Scale-ups: a Dedicated Team for an evolving roadmap.
- Enterprises: an ODC or BOT model to own, or eventually absorb, a full team.
How fast can you start a project for a US client?
After a discovery call and scope review, we typically share approved candidate CVs within days and kick off in 1 to 2 weeks. A 2-week risk-free trial lets you validate fit before committing.
Is my data and intellectual property protected?
Yes. We operate an ISO 27001-certified security management system, sign NDAs, and use role-based access with client-owned repositories. You retain full ownership of code and IP, and we support GDPR and HIPAA compliance for regulated industries.
