Senior engineers embedded inside AI-native teams building in healthcare, fintech, and regulated tech.
[Our Approach]
We take direct ownership of architecture, agentic systems, and the data infrastructure under AI-native products. Embedded inside your team. US-based, working globally.

In 2026 software gets written faster than at any point in this field's history. The decisions that carry a system through production stayed exactly where they were: schema design, access control, how the pieces fail. We work on the frontier of AI and hold the engineering standard that regulated systems demand.
In 2026 software gets written faster than at any point in this field's history. The decisions that carry a system through production stayed exactly where they were: schema design, access control, how the pieces fail. We work on the frontier of AI and hold the engineering standard that regulated systems demand.
brigit.dev does this work. Senior engineers embed inside the client's team, take ownership of defined parts of the system, and carry them through production. The setup is built for teams shipping AI-native products under real regulatory constraints.
Healthcare, fintech, compliance are the verticals where the data model carries legal weight and every access is audited. We've spent years inside those systems. The architectural patterns transfer: tenant isolation, audit trails, PHI handling, event ordering at scale. What changes is the product on top.

Why choose us
The way companies are built
is about to change.
The leverage moved to people who can take a defined part of the system and carry it end to end: architecture, implementation, production. We've operated that way for years in regulated verticals, and it's the model AI-native companies are converging on now.

We take ownership.
We don't sell hours.
Speed without sacrifice
Speed comes from senior engineers taking full ownership. The same team that scopes the architecture writes the code, ships the system, and stands behind it in production.
Embedded in your team
We integrate into your team and align on how the work runs: the cadence, the scope, the components we take on. Because we only work with senior engineers, this comes together fast. You keep product direction and founder context. We bring the engineering depth to match it.

Services
Areas of ownership
Areas where we've embedded with founding teams and delivered production-ready builds. Each represents years of work across regulated verticals, delivered by a senior team that ships repeatedly and can take ownership from day one.
[01]
AI-native architecture
The architecture underneath a production AI system: model orchestration, retrieval, tool calling, and the safety layer that lets it run in real environments. We design it end to end, coordinated with the data model and services around it, so what ships holds up under real load and scales with the product.

Agentic systems
Agents that read state, make decisions, and execute across live data in real time. We architect the reasoning layer, the tools they call, and the guardrails around every action - coordinated with the systems they operate inside, so what they do is auditable and safe under real load.

Real-time & event-driven systems
The data layer that keeps systems consistent as they scale: offline capture, ordered sync on reconnect, and event flow across services. We architect it end to end, tuned to how the data actually moves through your product.

Regulated data platforms
Sensitive data handled to the standard the regulation actually demands. This includes: encryption at rest and in transit, tenant isolation, audit trails on every access, and consent flows built into the model itself. Every layer designed to hold under regulatory scrutiny from day one.

Full-stack ownership
The full build under a single senior team: from architecture and infrastructure through backend, frontend, and data. Every decision is made in the context of every other layer, which is how systems ship coherent, hold under real load, and stay maintainable long after the engagement ends.

Process
How we work.
A way of working we've refined across dozens of embedded engagements - five things that define our work, regardless of scope, stack, or stage.
Same day
Contract to embedded work. We integrate on day one and gather context as we go, no separate discovery phase.
Sustained
The speed you see in the first week is the speed we hold across the engagement.
01
We own.
We take full ownership of the parts of the system we handle. Proactive thinking, edge cases covered, tight coordination with your team to actually get to the outcome. Onboarding takes days.
02
Senior team.
Working between SF and Europe, we are actively following the frontier of what's shipping in AI. Our clients get the benefit of a team that's already read the paper, tried the tool, and knows why it did or didn't matter.
03
Founder-minded.
Many of us have been founders. That means we've been in the rooms where things are unclear, high-stakes, and moving fast. We move forward without waiting for every detail, bring our network in when it helps, and hold the same accountability as the people we work with. We show up as partners
04
Focused capacity.
We take on few engagements at a time. That's how we hold quality and how we make sure the senior team is actually senior, on your work, not spread thin across five clients. Depth requires context, and context takes time to build. Fewer clients and long-term partnerships is what keeps the work senior.
05
No layers.
Direct communication with the people building. When something needs a decision, you're in the room. When something needs a call, we're on it that day. This is how we've worked with founding teams across dozens of engagements — because trust and speed both depend on it.

Philosophy
Our philosophy
We've built our careers by putting ourselves into rooms and problems we hadn't seen before, and figuring them out. Fifteen years of software engineering, deep in how systems actually work beneath the surface, from the low-level up. Technology has always been what we build our lives around. AI is the most consequential moment we've lived through in this field, and we intend to be part of what gets made in it. Excellence is the only standard we operate by. We commit fully to the problems we take on. And we are deliberate about who we do that with.

Answers to what founders usually ask first.
Have a question?
Reach out directly. We read every message. Most engagements start with a short call to see if we're the right fit.
Srdjan Ristanovic
Founder and CTO
Flexible. We take on few engagements at a time, so we align working hours with each client. Part of the team spends half the year in the US, half in the EU. Overlap is wide across both sides.
Senior only. Every engineer on the team has been shipping production software for over a decade. Architecture, systems programming, low-level work — before AI was the frame. We use now AI tools and follow everything that's happening on the frontier of the technology.
Yes. Engagements adjust to the work. We've spun up dedicated offshore teams built entirely around a client's product. We've also flexed down to a single embedded engineer when that's what the phase required.
AI-native is the only work we take on. Recent builds: streaming clinical copilots with multi-step tool calling into EHR modules. Ambient scribing pipelines. RAG across live patient records. Autonomous voice agents for scheduling and triage. Agentic recruitment platforms. All shipped to production under real compliance constraints: HIPAA, KYC/AML, GDPR.
We're engineers first. We work on the problem, not the vertical. Most of what we've shipped has been in regulated domains: healthcare (EHR, clinical AI, medical devices), fintech (compliant Web3, investment infrastructure), enterprise EdTech under GDPR.
Team augmentation, embedded with your founding team. We used to work project-based - full builds from zero to launch. Over the last year we moved to embedded engagements: senior engineers integrated directly into founding teams, owning entire parts of the platform end to end.
