The AI-Native Custom Software Partner
Custom software, AI strategy, and modernization, all backed by a guarantee.
We help B2B leaders adopt AI, build new software, and modernize aging systems.
Senior US-based engineers, AI-Native delivery, and the industry's only triple guarantee: fixed price, guaranteed outcome, and a 12-month bug-free warranty.
We help you ship and run modern software
We are your senior software partner, not an extra set of hands. AI-Native delivery means the same scope ships in less time and at a lower price than a traditional shop, and the triple guarantee is the proof it does not come from cutting corners. We think through the problem with you, ship production-ready software, and stand behind every line of it.
What's Your Gnarly Problem?
AI Strategy & Fluency
Become AI-Native
You need to adopt AI but your team hasn't started and you don't know where to start. We deliver the strategy, train your people, and ship the first automation, so the investment finally shows a return.
Custom Software Development
Build It Right the First Time
Build the software your business runs on, with a guaranteed price, a senior US-based team, and a 12-month warranty. Plan it right, build it once.
Legacy Software Modernization
Modernize Without the Migration Risk
Modernize the experience without ripping out the system you rely on, or rebuild it when the old stack can't be saved. Fixed price, guaranteed outcome.
Why Gnar?
Ten years, 100+ projects, $50M+ in product development. Here is what that buys you.
Guaranteed Price
No risk of your project cost ballooning and ruining your budget. Any overages are on us.
AI-Native delivery
Senior engineers ship with AI tooling as a teammate, so the same scope reaches production faster and at a lower price.
Guaranteed Outcome
We define success in writing up front. The software works the way we agreed, or we fix it at no additional cost.
Senior US team
No offshore, no junior bench. You get senior US-based engineers in your time zone, on every engagement.
12-month warranty
For a full year after launch, we fix any non-conforming code at no charge. Most agencies stop at 30 to 90 days.

We treat your product like we'd treat our own. A founder has eyes on every engagement.
“They never fail to deliver. Future clients should trust them and take advantage of their extensive knowledge and expertise.”

Building an Engine for Third-Party Integrations
WHOOP was growing fast, and their engineering team faced a backlog of third-party integrations. We stepped in as an extension of their team, building a robust testing application, creating self-service documentation, and streamlining onboarding for new partners.
By taking on these integrations, we freed up WHOOP’s engineers to focus on scaling their core product while creating a smooth experience for their partners.

Empowering Device Security with Collaboration
Kolide needed extra engineering support to expand their SaaS platform and develop mobile and desktop apps for secure device management. We embedded engineers directly into their team, helping them improve existing features and build new ones.
Together, we launched Kolide’s mobile app on Google Play and Apple App Stores, enabling secure device monitoring and keeping information protected.

20x User Base Growth & Shark Tank Success
When Qeepsake approached us, they had a promising prototype but needed help building an app to scale their vision. We built a cloud-based platform, optimized their onboarding UX, and integrated messaging and payment systems to enhance functionality.
Our work helped Qeepsake grow their user base by 20x and secure a deal on Shark Tank. Today, they’ve saved over 50 million memories for more than 700,000 families.

Frequently Asked Questions
We price by milestone, and the price is fixed before we start. The triple guarantee means the price holds, the outcome is guaranteed, and the build carries a 12-month bug-free warranty. The one exception is Embed, our staff augmentation model, which is billed time and materials because we are reinforcing your team rather than running the project.
Three things. AI-Native delivery, so the same scope ships faster and at a lower price. A 100% US-based senior team with a founder in every engagement. And the industry's only triple guarantee: fixed price, guaranteed outcome, and a 12-month bug-free warranty. Most agencies offer none of the three.
We help B2B leaders in three ways: AI Strategy & Fluency (adopt AI and ship a real automation), Custom Software Development (build the software your business runs on), and Legacy Software Modernization (modernize or rebuild an aging system). Every build is backed by the triple guarantee.
It depends on scope, but AI-Native delivery compresses the timeline. Work that takes a traditional shop six months often ships in three to four with us. We give you a milestone plan with real dates before the build starts.
For a full year after release, we repair any non-conforming code at no charge. The warranty is possible because our engineering practice is rigorous enough to stand behind it. It covers code that doesn't work as specified; feature additions and ongoing support are handled through our maintenance offering.
Yes. That's Embed, our staff augmentation model. Senior US engineers work as an extension of your team when you need velocity or a specific skill set. Embed is billed time and materials and is the one engagement that does not carry the triple guarantee.
The codebase is yours, documented for hand-off, and covered by the 12-month warranty. You can transition to your internal team with our support, or keep us on through Maintain, our optional monthly support retainer.
The AI-Native Custom Software Partner for B2B leaders.
We help you adopt AI, build new software, and modernize what you already run, all backed by the industry's only triple guarantee. Senior US-based engineers, AI-Native delivery, and software we stand behind for a full year.
