We build, modernize, and run Ruby on Rails software.

Whatever you need, JetEngine is how we deliver it. Every engagement runs through the same stages, Idea, Prototype, Build, and Ship, with senior Rails engineers accountable for the result.

🚀
Build a new product
Launch an MVP, a new platform, or an internal tool. Start with an idea. JetEngine turns it into requirements, a clickable prototype you approve, and a production release.
IDEA → PROTOTYPE → BUILD → SHIP
📈
Keep your product shipping
Add features and integrations to a live Rails application. Tell us what you want, like “add subscriptions.” JetEngine scopes it, shows it to you, builds it inside your architecture, and releases it safely.
IDEA → PROTOTYPE → BUILD → SHIP, CONTINUOUSLY
🛠
Upgrade and modernize
Move to current Rails, pay down technical debt, and add tests and documentation without stopping product work. The Build Engine works inside your existing architecture, with tests and review gates on every change.
BUILD → SHIP
🧯
Fix and rescue
A stalled project, a fragile codebase, or AI-generated code you don't trust? We audit it, tell you plainly what's wrong, and bring it up to JetRockets standards so it's safe to keep building on.
AUDIT → BUILD → SHIP
🎨
Design and mobile
Product design, design systems, and iOS and Android apps on the same Rails backend. The Prototype Engine gives you clickable flows to react to before anything is built.
PROTOTYPE → BUILD → SHIP
⚙
Bring JetEngine to your team
Already have engineers? We set JetEngine up in your environment, train your team to run it, and stay on for oversight, with fractional CTO leadership if you need it.
YOU RUN IT, WE OVERSEE

Every engagement includes QA, DevOps, and monitoring in production. You own the code. We don't bill hours.

The problem is no longer access to AI.

It's knowing how to use it safely when you're not technical.

AI makes software look deceptively easy.

You can ask ChatGPT for requirements, generate screens, have an agent write the code and deploy it. Then the hard questions start:

?
Did I explain the feature correctly?
?
Is the code actually good?
?
Did we create a security problem?
?
What did the AI miss?
?
Is this safe to ship?

AI gives you more power, and more decisions you shouldn't have to make. You don't want to become a product manager, architect, QA engineer, DevOps engineer, and security reviewer just to ship a feature.

That's why we built JetEngine. AI does much of the work. Our standards and senior engineers answer those questions for you.

Four connected Engines. One system.

The Engines share context, standards, and quality controls. The output of each stage becomes structured input for the next.

IDEA ENGINE
What should we build?
Guided discovery, decisions, edge cases, requirements, and acceptance criteria.
PROTOTYPE ENGINE
What should it feel like?
Clickable flows using your existing design system or an agreed visual direction.
BUILD ENGINE
How do we build it safely?
Implementation within your codebase's architecture, with tests, security checks, and review gates.
SHIP ENGINE
How do we run it reliably?
CI/CD, infrastructure, monitoring, backups, rollback, and operational escalation.

Each Engine encodes JetRockets methodology, not just access to an AI model.

JetRockets knowledge is built in.

Used directly, an AI model chooses the architecture, patterns, UI components, tests, and deployment approach on its own, and a nontechnical owner has no reliable way to know whether those choices are good, or safe. We don't ask AI to decide how good software should be built every time.

Build Engine
AI works inside predefined JetRockets standards
✓
Coding conventions
✓

Ship Engine

✓
Approved infrastructure patterns
✓
CI/CD conventions
✓

The AI can change. The JetRockets system stays: our standards, guardrails, and judgment define how the work gets done.

Two ways to use JetEngine

We set JetEngine up on your codebase. Then you choose how it runs.

Fully managed · We run it
You set priorities and approve outcomes
We configure and operate the workflows, handle exceptions, and own delivery accountability, month after month.
Build & own · You run it
Your team operates the workflows
We configure JetEngine in your environment, train your team to run it, and stay on for support and oversight.

Either way, senior JetRockets engineers stay accountable for what ships, you own your code and data, and you pay for software that keeps shipping, not for hours.

Not an AI cockpit. A guided way to build.

SAY WHAT YOU WANT
“Add subscriptions.” “Create a partner portal.” “Let customers invite an accountant.”
ANSWER BUSINESS QUESTIONS
JetEngine surfaces only the decisions you're actually the right person to make.
SEE IT BEFORE WE BUILD IT
Review the proposed requirements and a clickable prototype. Misunderstandings get corrected early, when they're cheap.
APPROVE THE OUTCOME
JetEngine handles implementation, checks, and release gates. Senior engineers step in when judgment is required.

You shouldn't need to become technical to own and evolve your software.

Why Rails + AI works

Ruby on Rails has always been about developer leverage: conventions, mature abstractions, and accomplishing more with smaller teams.

AI compounds that advantage.

JetRockets has spent more than 15 years building production Rails applications. That experience gives our engineers the context to direct, review, and validate AI-generated work instead of blindly accepting it.

AI makes code inexpensive.
Experience makes it production-ready.

“

After evaluating several options, JetRockets was the clear winner. They followed through exactly to spec with daily updates and speed beyond what was promised. The engineers were self-guided and required zero oversight.

JetRockets is so much more than a dev team - they are a core part of Safari Portal and of our family. They truly care about the product and its success and it shows in everything that they do - every feature, every task, every question. I am excited to see what we create together in the future.

Deep Rails expertise still matters

AI didn't make technical expertise less valuable.

It made it more leveraged.

We've spent 15+ years working almost exclusively with Ruby on Rails applications. We've seen the architectural mistakes, scaling problems, upgrade challenges, integration failures, and technical-debt patterns that production Rails systems accumulate.

That experience tells us what to ask AI to do — and when not to trust the answer.

We also show up for Rails in public. We maintain Jet UI, an open-source Rails component library built on ViewComponent, Tailwind, and Stimulus, published as the jet_ui gem. Our CTO, Igor Aleksandrov, is a Docker Captain, and we have been a Gold Sponsor of Tropical on Rails two years running.

JetRockets is a women-owned Ruby on Rails company headquartered in Brooklyn, New York. Founded in 2012 and led by its co-founders, Natalie Kaminski, Igor Aleksandrov, and Aleksei Solilin, we have worked almost exclusively on Rails for more than 15 years.

Frequently asked questions

JetRockets is a senior Ruby on Rails company in New York. We build new products and MVPs, add features to live applications, upgrade and modernize aging Rails codebases, rescue stalled projects and fix AI-generated code, and design and build the web and mobile apps around them. We then keep that software running in production. All of it is delivered through JetEngine, our AI-powered delivery system, either as a fully managed service or set up inside your own engineering team.
JetEngine is how JetRockets builds software with AI. It is four connected stages, Idea, Prototype, Build, and Ship, that share context, standards, and quality controls, so the output of each stage becomes structured input for the next. AI coding agents do much of the execution, but they work inside our coding conventions, architecture patterns, testing and security rules, and infrastructure patterns rather than deciding from scratch how software should be built. High-risk changes trigger checks and review by our senior Rails engineers. It is not a proprietary AI model, a chat wrapper, or a Rails gem you install. It is 15 years of JetRockets practice turned into a repeatable system.
No. You describe the business outcome in plain language, such as "add subscriptions" or "let customers invite an accountant". JetEngine asks the product questions that matter and surfaces only the decisions you are the right person to make. You review the requirements and a clickable prototype before anything is built, then approve the outcome. Implementation, testing, security checks, and release gates are handled for you, and senior engineers step in wherever judgment is required. If you have an engineering team of your own, we can instead set JetEngine up in your environment and train them to run it.
Our senior Rails engineers direct AI coding agents across the whole development lifecycle. Agents implement features, write tests, refactor code, investigate bugs, and document systems. Our engineers own architecture, product decisions, system design, quality, security, and production reliability, and they review and validate what the agents produce instead of accepting it blindly. The result is more engineering output from a small, experienced team, without adding headcount at the same rate.
A Ruby on Rails agency designs, builds, modernizes, and maintains web applications on the Rails framework. In practice that is four kinds of work: building a new product, rescuing one that has stalled, upgrading an application that has fallen behind on Rails versions, and keeping a live platform fast and secure once it is carrying real traffic. Most agencies that offer Rails offer four or five other stacks alongside it. JetRockets does not. We are Rails-only, which is why we can usually tell you what is wrong with your application in days rather than weeks. Today much of the execution is done by AI coding agents, directed and reviewed by our senior Rails engineers.
We don't publish a price list, because every product is different. Engagements start with a one-time setup for a defined outcome, followed by a flat monthly service for ongoing delivery, operation, and maintenance. QA and DevOps are always included, and we don't bill hours. We scope pricing on a call once we understand what you need. If you want to see how we work before committing to anything, a free Rails code audit is a good first step.
Kickoff is typically within one to two weeks of the agreement being signed. We don't publish build durations, because every product is different: setup ends with your first release in production, and we commit to a timeline after the assessment. After that, changes ship continuously, with a demo before each release, so you always know what shipped and what is next. Clients see delivery roughly 40 percent faster than building the same team in-house, and most of that gap is not talent. It is that we are not learning Rails on your schedule.
Yes. Security audits, dependency and CVE remediation, and hardening are core services, and we have taken production Rails applications through SOC 2 and HIPAA requirements in fintech, healthtech, and legal tech. Every new build carries a 30-day bug fix guarantee. If you are not certain whether you have a security problem, the free Rails code audit covers architecture, performance, and security and comes back as a written report in two to three days.
Yes, and it is a large share of what we do. Scaling work almost always starts with the database rather than the servers. N+1 queries, missing indexes, and unbounded result sets account for most of the Rails slowdowns we are called in to fix. From there it moves to caching, background jobs, and read replicas, and only then to running more machines. We work with zero-downtime deployment, so the fix does not need a maintenance window.
The co-founders stay. Every JetRockets engagement is led by Natalie, Igor or Alexei rather than handed to a junior team once the contract is signed, so the people who understand your architecture and your business context do not change when a developer rotates off. People move between teams at every agency, ours included. The question worth asking a prospective partner is not whether that ever happens. It is whether the knowledge walks out of the door with them. Ours is built so that it does not.
You do. All intellectual property, all source code, all repositories, transferred to you and yours to keep. There is no lock-in, no proprietary framework you have to keep paying us to maintain, and no clause that makes leaving expensive. We work under a mutual NDA from the first conversation.
JetRockets is headquartered in Brooklyn, New York, and every engagement is led from New York. Our engineering team is distributed across Europe and, since 2024, Latin America. Between the two regions the working day runs long, so work carries on after your team logs off rather than pausing until morning.
