Software Development in Bethesda, From Our North Bethesda Office

Updated

Sthenos Technologies builds custom software, AI systems and data platforms for employers around Bethesda and Rockville. Our Maryland office is at 11810 Grand Park Avenue in North Bethesda.

Who Buys Software Around Bethesda

Sthenos Technologies keeps its Maryland office at 11810 Grand Park Avenue, Suite 500, North Bethesda, MD 20852. The number there is 301-793-3980. Our headquarters is at 1775 Tysons Blvd, 5th Floor, Suite 04187, McLean, VA 22102, on 703-945-5300, so buyers on either side of the Potomac deal with the same company.

Look at what sits around this office. The NIH campus is close by, and the biotech, clinical research and health services employers along the same corridor run on data that has to be handled under rules rather than on generic office software. Add the law firms, financial advisers and federal contractors with offices in and around downtown Bethesda, and the recurring problem looks the same from the outside: systems holding regulated information, several teams needing to read that information differently, and an architecture that was never designed for the way the business works now.

One thing worth being plain about. We name the NIH campus and the Maryland health and biotech corridor to describe the market around this office. They are not a client list, and nothing on this page is a claim about who we have worked for.

Our Services

The Work This Office Takes On

Software for Regulated Data

Applications holding clinical, financial or privileged information, where access control, retention and the audit trail are designed in rather than added afterwards. That is the shape of the work whenever the buyer answers to a regulator.

AI Over Your Own Documents

Retrieval and agent systems built on a client library rather than on a general model alone, with provenance attached to every answer so a reviewer can see where it came from. It matters wherever a wrong answer has a consequence and a person has to defend it.

Data Engineering and Reporting

Pipelines and reporting layers that give research, finance and operations the same number. This is what replaces the set of spreadsheets each team has quietly built for itself.

Legacy System Modernization

The system that still runs the place and nobody wants to touch. We read what it actually does, split it into parts that can be replaced one at a time, and rebuild without a single cutover weekend.

Engineers Into Your Team

Staff augmentation for teams around Bethesda and Rockville that need capacity rather than a separate project. Our engineers sit inside the setup you already run, using your board, your branch rules and your code review, for an agreed stretch of time.

AI Systems With an Audit Trail

A demo is not a system. Sthenos builds the parts that let one go into daily use: retrieval over your own data, evaluation you can repeat, and a record of what the system saw and why it answered as it did. Read how we build them.

Why Teams Around Bethesda Call Us

Close Enough to Meet

The Maryland office is at 11810 Grand Park Avenue, Suite 500, North Bethesda, MD 20852, on 301-793-3980. For a team in Bethesda, Rockville, Chevy Chase or Silver Spring that is a drive rather than a flight, which changes how much you actually see the people building your system.

Two Offices, One Contract

Maryland work is delivered from North Bethesda alongside our headquarters at 1775 Tysons Blvd, 5th Floor, Suite 04187, McLean, VA 22102, on 703-945-5300. Whichever office you walk into, it is the same company, the same contract and the same accountability.

Scaled Through NeoSOFT

Where an engagement outgrows a small team, delivery scales through our formal partnership with NeoSOFT. The commercial relationship and the people you talk to stay with Sthenos.

Custom Software Is the Primary Business

Our primary NAICS code is 541511, Custom Computer Programming Services. That is not a marketing line, it is the classification on the federal record, and it describes what this office sells: building software, rather than reselling or supporting somebody else’s.

Small Business Status on the Federal Record

STHENOS LLC is certified by the SBA as an Economically Disadvantaged Women Owned Small Business and a Women Owned Small Business. Unique Entity ID ULUZGKWYCJB7, CAGE code 9RX92, SAM.gov registration active to 24 June 2027.

Public Reviews, Not References on Request

Clutch lists Sthenos at a 5.0 rating across 43 verified reviews. Google lists a 5.0 rating from 5 reviews. Both profiles are open, so you can form a view before you get in touch.

Bringing us a half-built system

A stalled build, a codebase inherited from a team that has since left, or a platform that works but cannot be changed safely are all normal starting points. The order of work below restates this page's own answers on half-built projects and on legacy system modernization.

  1. Read what existsThe first piece of work is reading what the system actually does.
  2. Finish, refactor or replaceWe tell you honestly which it should be, with the reasoning attached so you can disagree with it.
  3. Split it into partsParts that can be replaced one at a time, because the system still runs the place.
  4. Rebuild in stagesWithout a single cutover weekend, with working software arriving every two weeks.

If the system is an AI prototype that has to go in front of real users, the checklist we work through first is our production readiness checklist, and a single red check blocks the release on its own.

How a rule you work under shapes the design

Clinical research groups, health services companies and the professional firms serving them all hold data under rules. Where a client works under HIPAA, a research data agreement, financial services rules or legal privilege, those requirements shape four decisions before anything is built, and the result is written down as a split of responsibility.

Figure 1. From the rule you work under to a written split of responsibility

Four kinds of rule a client can work under (HIPAA, a research data agreement, financial services rules, legal privilege) shape four design decisions before anything is built (the data model, the access controls, the logging, the hosting decisions), and the result is a written split of responsibility between controls built into the software and controls the client's own team runs.THE RULE YOU WORK UNDERDECIDED BEFORE THE BUILDA WRITTEN SPLITHIPAAThe data modelA research data agreementThe access controlsFinancial services rulesThe loggingLegal privilegeThe hosting decisionsBuilt intothe softwareRun by yourown teamAll four are decided before anything is built, then written down as a split of responsibility.

Every label restates this page's answer to the question on compliance requirements like HIPAA. The figure shows the order of the decisions; it measures nothing and implies no certification.

What Sthenos does not hold, as of 10 September 2026: no SOC 2 report, no HITRUST certification and no ISO 27001 certificate. Where a standard calls for a certification we do not hold, we say so rather than let you assume otherwise, and the full list, with what we do instead, is on our about page.

Bethesda Questions We Get

Our Maryland office is at 11810 Grand Park Avenue, Suite 500, North Bethesda, MD 20852, and the number is 301-793-3980. That is North Bethesda rather than downtown Bethesda, which is worth knowing before you set off.

Our headquarters is at 1775 Tysons Blvd, 5th Floor, Suite 04187, McLean, VA 22102, on 703-945-5300. Either office can host a working session.

 

Those are the kinds of buyers our services fit. Clinical research groups, health services companies and the professional firms serving them all hold data under rules, and all need software that can be explained to an auditor as well as used by staff.

We should be plain about one thing. This page mentions the NIH campus and the Maryland health and biotech corridor to describe the market around our office. That is market context, not a client list, and we make no claim here about who we have worked for.

 

Yes. A stalled build, a codebase inherited from a team that has since left, or a platform that works but cannot be changed safely are all normal starting points.

The first piece of work is to read what exists and tell you honestly whether it should be finished, refactored or replaced. That answer comes with the reasoning attached, so you can disagree with it.

 

As design constraints. Where a client works under HIPAA, a research data agreement, financial services rules or legal privilege, those requirements shape the data model, the access controls, the logging and the hosting decisions before anything is built.

Expect a written split of responsibility: the controls built into the software, and the ones your own team has to run. Where a standard calls for a certification Sthenos does not hold, we will say so rather than let you assume otherwise.
