What we do

Four ways we move the needle.

Pick the engagement shape that matches the bottleneck in front of you. Every path ends in working software and clearer decisions.

Senior build

Rapid Prototyping

Turn a fuzzy product idea into something stakeholders can click, test, and react to in weeks instead of quarters.

Best for

New bets, internal tools, and decision-making under uncertainty.

Typical outcome

A working prototype and a clear next-build call.

Prototype my idea

Senior build

AI Automation

Remove repetitive operational work with AI systems and custom agentic workflows that classify, draft, route, and follow through where people are losing time.

Best for

Support queues, inboxes, research loops, and back-office workflows that benefit from AI decision support.

Typical outcome

A measurable automation or agentic workflow with human review where it matters.

Automate my workflow

Senior build

Custom Software

Build revenue-critical products or internal platforms with engineers who can own architecture, delivery quality, and the rough edges.

Best for

Teams that need maintainable software without hiring a full internal squad first.

Typical outcome

Production-ready software with a handoff your team can actually use.

Build my product

Senior build

Strategic Modernization

Untangle brittle legacy systems without pausing the business. We modernize in slices so the risky parts get safer fast.

Best for

Aging apps, fragile integrations, and teams blocked by old architecture.

Typical outcome

Incremental migration with less operational risk and less drag on delivery.

Modernize my stack

Who we are

Senior engineers. Directly involved.

3B is a small delivery team built for prototypes, custom software, custom agentic solutions, and modernization work that benefits from senior judgment from day one.

Direct collaboration

The people shaping the approach are the people building, demoing, and handling tradeoffs with you.

Working software early

We move in short cycles so you can react to prototypes, automations, and migrations before risk compounds.

Custom agentic solutions

When AI belongs in the workflow, we design agentic systems around your tools, approvals, and operating reality.

No committees, no handoffs, no waiting for a second team to translate the work. Every engagement stays close to the decisions and close to the code.

How we work

A loop, not a handoff.

You're in the room the whole time. We build in short cycles, demo constantly, and course-correct fast.

01

Discover

You bring the context, we bring the questions. Shared plan — no surprises.

You approve the plan first.

02

Build & Show

Short cycles, weekly demos. You see real progress and steer in real time.

You drive the direction.

03

Ship & Learn

We ship, monitor, and iterate. If something needs tuning, we're on it.

We stay engaged after launch.

Rinse and repeat
