The triple guarantee
The Only Firm To Offer A Triple Guarantee
Guaranteed Price
The number we quote is the number you pay. Any overage is on us.
Guaranteed Outcome
We define success in writing. The software works the way we agreed, or we fix it free.
12-Month Warranty
For 12 months after launch, we fix any code that doesn't work the way we agreed, at no charge.
Senior engineers, powered by AI
Our senior US engineers use AI agents to write the code, and they check every result before it ships.
Internal tools for your team
A small, well-scoped tool your team keeps asking for, shipped in weeks and hooked into the systems you already run.
Old systems fixed or rebuilt
We help you decide whether to fix or rebuild the system you run on today. Then the same senior team does the work.
Prototypes to production
You have a prototype that works in a demo but not in daily use. We take it to production, with the security, tests and alerts it needs.
Case studies
Our client work
Gridly
We built Gridly’s home electrification platform from zero.
It launched in March 2023. Elephant Energy acquired Gridly about 18 months later.
AARP Foundation
Applications take 40% fewer clicks, on average.
We rebuilt 14 of the AARP Foundation’s tools on React and Ruby on Rails.
GSC Enterprises · Claude Code program
Review comments on code changes fell by about 90%.
GSC’s automated reviewer commented on nearly every code change. After a four-week Claude Code program with Gnar, it commented on under 10%.
Counter Culture Coffee · AI roadmap
$1.5M in potential savings from the top 10 AI ideas.
We held 15+ interviews with leaders and staff. Then we ranked 79 ways AI could help.
Verified reviews
4.8/5 from 20 verified reviews on Clutch
Work was accurately estimated and completed within the timeframes planned.
Our engineering team spent a fraction of their time (from many hours per week down to < 1 hour per week) supporting API customers.
Since Gnar started working with the AARP Foundation Property Tax-Aide, these digital tools have helped over 28,000 people apply for and, if eligible, obtain over $10M in property tax relief.
…they help make important business decisions; they acknowledge what I want to do but also help me understand the alternatives we have. In a nutshell, their thoughtfulness and communication have blown me away.
Our system is quite complicated, and Gnar was really able to be productive quickly without a lot of ramping up.
Delivery was on time and the team was responsive and professional during the entire process with weekly checkin meetings.
From the first conversation, Pete and Mike were open and curious about our project and, more importantly, about our company and how this project helped us help our clients.
…we ended up agreeing with 100% of their change requests because they were so well explained.
…they offered out great ideas, more efficient ways things could be done if applicable and were cost conscious. I would recommend them to anyone.
They care about the quality of their work, and the satisfaction of their clients. They take the time to understand what you are trying to achieve.
I would describe the engagement as highly successful.
They were really great partners, not only in getting the work done but also in helping us drive the software in the right direction.
I very rarely have to over-prescribe the work, Alex does a great job of listening to stakeholders which requires less work for me to best define a solution.
We like that they are a small, nimble company like we are, and that they are invested in our success.
It was always easy to work with the company founders, who went out of their way to meet our needs
The team also responds to pivots in priority very well and are willing to dig into problems with you to make sure the solution is right.
Future clients should trust them and take advantage of their extensive knowledge and expertise.
They did a good job of jumping in and learning the in's and out's of the application quickly to begin building right away.
Creative, timely, flexible, organized, personable, and strong technical skills.
They were able to advise us on good long-term approaches and strategies for frontend development.
Who builds your software
100% US-based senior engineers
Two or three senior engineers and a Gnar product manager, in your time zone. The same team that runs your Discovery builds your software. We do not use junior developers or offshore teams.
You own the code
We build in your own cloud account, such as AWS. You get the code and the docs to run it.
Every result checked
We define success in writing. Our engineers check every result before it ships, and the tests run again with every change.
Your team talks directly to the senior engineers building your software. We can build alongside your own engineers, or hand the software to them.
