Sthenos Technologies is a US-based enterprise software development company headquartered in Tysons, Virginia, with an office in North Bethesda, Maryland. We build custom enterprise software: secure, scalable web and mobile applications, AI and machine-learning systems, and cloud platforms, and we modernize legacy enterprise systems. A senior Sthenos team stays accountable on every engagement, and through our partner NeoSOFT we add enterprise-scale delivery capacity, so you get boutique accountability with the throughput a large program needs.

Custom enterprise software development services

  • Enterprise web applications: secure, scalable portals, dashboards, and internal platforms, built end to end.
  • Enterprise mobile apps: native and cross-platform apps for employees, partners, and customers, integrated with your systems.
  • AI and machine learning: forecasting, document and process automation, and AI assistants, engineered for production at scale.
  • Cloud and data platforms: architecture, migration, and data pipelines on AWS, Azure, and Google Cloud.
  • Systems integration: connecting to ERP, CRM, identity, payment, and data systems across the enterprise.
  • Legacy modernization: re-platforming and rebuilding aging enterprise systems while preserving data integrity and uptime.

Built to pass an enterprise vendor review

Enterprise software fails when security, integration, and reliability are an afterthought. We build them in: access controls and audit logging, encryption, a documented SDLC, and architecture designed for scale, uptime, and the vendor security reviews enterprise procurement runs. We work with your security, IT, and architecture teams rather than around them. Where enterprise-scale certifications matter, we reference our partner NeoSOFT accurately rather than claiming them as Sthenos’s own.

From prototype to production-ready

Enterprise teams often build a working prototype, sometimes with AI tools, then stall before launch because enterprise production means security, integration, and reliability a demo never had. We take prototypes, including AI-built ones, from proof of concept to secure, scalable, monitored production, with the controls enterprise buyers require.

Who we build enterprise software for

  • Large commercial organizations: internal platforms and customer software that have to scale and integrate.
  • Regulated enterprises: finance, healthcare, legal, and technology teams that need security and auditability.
  • Government agencies and primes: as an EDWOSB small business (NAICS 541511, active on SAM.gov), we support enterprise-scale public programs and set-aside goals.
  • Product and platform teams: senior engineering capacity to build and scale, fast.

Why enterprise teams choose Sthenos

  • Boutique accountability, enterprise scale: a senior Sthenos lead owns your engagement, with partner NeoSOFT adding delivery capacity when the program needs it.
  • Security and reliability first: we build to pass enterprise vendor security reviews and to run reliably at scale.
  • Senior, accountable team: not a rotating bench, a senior team that stays with your program.
  • EDWOSB and WOSB certified: a certified small business for agencies and primes with set-aside and supplier-diversity goals.

Enterprise software development FAQs

What is enterprise software development?

Enterprise software development is the design and building of secure, scalable software for large organizations, such as internal platforms, customer applications, integrations, and data systems, built to meet enterprise requirements for security, integration, and reliability.

Can a boutique firm deliver at enterprise scale?

Yes. A senior Sthenos team stays accountable on your engagement, and through our partner NeoSOFT we add enterprise-scale delivery capacity, so you get boutique accountability with the throughput a large program needs.

How do you handle enterprise security reviews?

We build with access controls, audit logging, encryption, and a documented development process, designed to pass enterprise vendor security reviews. We engineer our part to support your security and compliance requirements.

Can you integrate with our ERP, CRM, and identity systems?

Yes. We build integrations across ERP, CRM, identity, payment, and data systems so your software works with the rest of the enterprise.

Can you take an AI-built prototype to enterprise production?

Yes. Moving prototypes, including AI-built ones, from proof of concept to secure, scalable, monitored enterprise production is a core focus for us.

Enterprise software development at Sthenos is the same engineering as our software development services, carried with the governance, integration surface and scale an enterprise programme needs. The six services above are what that covers, from enterprise web applications to legacy modernization. The sections below draw them as one estate, compare the ways to buy an enterprise programme, and set out the playbook from prototype to production, what a vendor review looks for, what moves the cost, what you receive and what to ask.

Enterprise application development services, drawn as one estate

Figure 1 draws the six enterprise software solutions on this page as one estate around the software they add up to, with the review they are built to pass underneath, in the page's own words.

Figure 1. Six services, one enterprise estate, and the vendor review underneath it

In the centre, custom enterprise software: secure and scalable, integrated with the rest of the enterprise. Around it, six services. On the left: enterprise web applications, meaning portals, dashboards and internal platforms; enterprise mobile apps for employees, partners and customers; and AI and machine learning for forecasting, automation and AI assistants. On the right: cloud and data platforms on AWS, Azure and Google Cloud; systems integration with ERP, CRM, identity, payment and data systems; and legacy modernization, re-platforming while preserving data integrity. A band underneath: built to pass an enterprise vendor review, with access controls and audit logging, encryption, a documented SDLC, and architecture designed for scale and uptime.

Engagement models for an enterprise programme, compared

Sthenos publishes four engagement models and what each contract commits. What changes between them is who carries the risk of the scope moving; the rate band and the costed roadmap sit under all four.

Who carries the risk when the scope moves

ModelWhat you are buyingBest forWhere it goes wrong
Fixed priceAn outcome; the vendor carries the estimating riskA settled specification, a discrete phase or a bounded discoveryEvery change becomes a negotiation
Time and materialsCapacity at the published rate band; you carry the scope riskEvolving products and work that follows what users doNo ceiling unless you set one deliberately
Dedicated teamA standing team, priced monthly, the same people across quartersContinuous product workYou pay for the capacity even in a quiet quarter
Staff augmentationEngineers inside your own process, board and code reviewYou already have the plan and the managementYou own the outcome, so weak internal direction shows up fast

The playbook from prototype to enterprise production

The section above, From prototype to production-ready, describes teams that build a working prototype, sometimes with AI tools, and stall before launch. Our guide to taking an AI-built prototype to production sets out the seven steps of work between the two.

  1. Code review and hardeningRead what was generated, fix security issues, remove exposed secrets and add proper access controls.
  2. Add testsAutomated tests, so future changes do not silently break things.
  3. Fix the architectureReplace demo-grade shortcuts with structure that holds up under real load and change.
  4. Set up infrastructureReal hosting, environments, backups and a safe deployment process.
  5. Monitoring and error handlingKnow when something breaks before your users do.
  6. Address complianceIf you touch regulated data, build in the controls regulated buyers and government reviews require.
  7. Document and hand offSo the system can be maintained, not just launched once.

Once that work is claimed to be done, our production readiness checklist is the other half: seven areas you score, from reliability and failure behaviour to ownership and operations.

What an enterprise vendor review looks for

The section above names what goes in from the start: access controls and audit logging, encryption, a documented SDLC and architecture designed for scale and uptime. The eight cards restate the practices our custom software development and penetration testing pages define behind words like those, each one something a reviewer can open rather than a claim.

Threat modellingDone before the first commit, alongside abuse cases written with the user stories.
Authorization at the boundaryChecked at the boundary rather than in the interface.
Secrets and credentialsSecrets held outside the codebase, and standing credentials that do not survive a person leaving.
DependenciesPatched on a schedule, and a known-vulnerable one fails the pipeline.
Code reviewEvery change read by a second engineer before it merges, by a reviewer who can block the merge.
ObservabilityLogs, metrics, traces and alerts that reach somebody who can act.
Release and rollbackA controlled release, with the rollback path decided before the deployment.
RunbooksA runbook names the failure, the check, the fix and the escalation.
Certifications are a separate question. As the vendor review section above says, where enterprise-scale certifications matter, we reference our partner NeoSOFT accurately rather than claiming them as Sthenos's own.

What moves the cost of enterprise software

Enterprise work is billed at the published Sthenos rate band, and where the scope is clear we quote a fixed price for a defined outcome, with a costed roadmap before any build starts.

Hourly rate, by the seniority and mix of the team $150 to $250
$0$250 per hour
What a typical Sthenos project runs $50,000 to $200,000
$0$200,000

No two quotes for the same brief are comparable until you know which of these each vendor assumed. None carries a number here.

Seniority and mix of the teamThe stated reason the rate band has a range at all.
How settled the scope isA settled scope can be quoted as a fixed price; an unsettled one priced as settled is where the buffer comes from.
Team size and durationThe same total effort costs differently spread over two quarters than compressed into one.
Systems it has to talk toEvery integration adds a counterparty whose availability, data quality and release calendar you do not control.
The control framework namedWork scoped against a named framework carries evidence, review and documentation the same build would not otherwise need.
How scarce the technology isA rare stack narrows the pool of engineers, which shows up in the rate rather than in the hours.
Data migrationReconciling data, and proving it moved correctly, is the hard part of moving it.
What happens after launchA quote that stops at go-live is not cheaper, it is shorter. Get deployment and maintenance priced up front.

What you receive from an enterprise engagement

A process description says what a vendor does. This says what you end up holding, as Sthenos publishes it.

  • The repository and the cloud accounts, in your name from the first commit.
  • A written scope and a costed roadmap, before any build starts.
  • Working software every two weeks, not a status report about software.
  • Architecture and a security posture you can put in front of a reviewer.
  • Infrastructure your own engineers can run once it is handed over.
  • Monitoring, maintenance and a roadmap after launch, priced up front.

What to ask any enterprise software development services company

These apply to any of the enterprise software development companies on your shortlist, Sthenos included, and each one is already published on this site.

  1. Who writes the code: named engineers, their seniority, and whether they are employed or subcontracted?
  2. What happens when the estimate is wrong? The answer tells you how the relationship will actually work.
  3. What documentation is a contractual deliverable, not what you promise to write?
  4. Will the named engineers be on the contract, with a notice clause if they change?
  5. Where are the engineers physically? Data residency, contract terms and your own compliance review depend on it.
  6. What would make you decline the requirement?

Enterprise software questions buyers ask next

How much does enterprise software development cost?

Sthenos rates are $150 to $250 per hour, depending on the seniority and mix of the team, and a typical project runs $50,000 to $200,000. Where the scope is clear we quote a fixed price for a defined outcome, with a costed roadmap before any build starts.

How long does an enterprise software project take?

Sthenos works in two week sprints, so working software arrives every two weeks and a first production release typically lands in three to six months. A date more precise than that comes out of discovery, because it depends on scope.

Who owns the code you write?

You do, entirely, from the first commit. The repository and the cloud accounts are in your name, with no licence back to us and no dependency on us continuing to exist.

Do you work with government agencies and primes?

Yes. Sthenos Technologies is an EDWOSB and WOSB-certified US firm, NAICS 541511, active on SAM.gov, and it builds and modernizes custom software for federal, state and local agencies, supporting enterprise-scale public programs and set-aside goals.

Can you take over enterprise software somebody else built?

Yes. Legacy system modernization is one of the services we sell, and taking over an existing codebase is one of the ways it starts. Send us access to the repository, or a description of the system, and we will tell you what we think it would take.

Do you use AI to build enterprise software?

Yes. Sthenos builds with AI-assisted engineering, and AI-assisted code takes the same route to production as any other: code review, hardening, testing, infrastructure and monitoring, then scored against our published production readiness checklist.
