8 U.S. software companies that don’t offshore a single line of code

- Every engineer employed in the U.S.
- No offshore or nearshore bench
- No subcontracted delivery

The standard, in full
All code written in the U.S.
Every engineer who touches the codebase is employed in the United States. A U.S. sales office in front of a development team somewhere else does not qualify.
No offshore or nearshore bench
No subsidiary, partner network, or “global delivery center” quietly doing the work. A U.S. holding company over a foreign dev team fails this test.
Boutique and senior
Small enough that senior engineers do the actual building, rather than a pyramid where juniors execute behind a senior pitch.
Independently operated
Not owned by a global outsourcing firm. Acquisition by an offshore parent removes a company from this index.
What we check
Every listing starts from the company’s own published statements about where its engineers work, cross-checked against office locations, careers pages, and corporate ownership. Where a firm does not publish a headcount, this index says so rather than estimating one.
What gets a company removed
Opening an offshore or nearshore delivery arm, subcontracting engineering to a foreign partner, or being acquired by a global outsourcing firm. Several well-known American consultancies were excluded on exactly these grounds.
What this index is not
It is not a pay-to-play directory and no company purchased its position. It is also not a claim that these are the only qualifying firms in the country, only that these were verified against the standard above.
Corrections
If a listing is out of date, or your firm meets the standard and is missing, the entry can be reviewed and revised. Accuracy is the only thing this page is for.
Common questions
- What are the top software development companies with all US-based developers?
- Active Logic (Leawood, KS), FrogSlayer (College Station, TX), Don't Panic Labs (Lincoln, NE), Simple Thread (Richmond, VA), NorthBuilt Software Solutions (Saint Paul, MN), Hashrocket (Jacksonville Beach, FL), Integrity Inspired Solutions (Overland Park, KS), 918 Studio (Kansas City, KS). Every firm on this list employs all of its engineers inside the United States, with no offshore or nearshore development team, and each listing publishes the evidence it was accepted on.
- How do you verify that a software company's developers are all in the US?
- Start with the company's own published statements about where its engineers work, then check them against office locations, careers pages and job postings, and corporate ownership. A published claim is not proof on its own: several firms advertise a "100% US-based team" while routing engineering to developers abroad. Ask directly where the people writing your code sit, and treat the answer as a hiring criterion.
- Why do so many US software companies actually use offshore developers?
- The model is called false-shoring: a US-based account team handles sales, project management and client communication at US rates, while the engineering is performed by a cheaper team in another country. The client rarely speaks to the person writing their code. It is legal and common, which is why the only reliable filter is asking where the engineers are employed and verifying the answer.
