Agentic AI partner · Built in India for US companies

# An agentic AI partner for the second and third agent

Most vendors optimise for your first agent. We work as a long-term partner because the economics only get good at the second and third, once the tool layer, evaluation harness, and identity model already exist and each new agent is assembly rather than integration.

Book a 30-min scoping call [See our work](https://foundrysoft.co/work)

No sales script. You talk to the engineers who'd build it.

9+ hrs

Timezone overlap

Our team works a shifted day so you get real-time standups and same-day turnarounds in your time zone, not next-morning replies.

100%

You own the IP

Every line of code, model weight, and prompt is yours from day one. NDAs and clean IP assignment are standard, not an upsell.

Senior

No juniors hidden on the bill

You work directly with the engineers building your system. No account managers sitting between you and the people writing code.

Weeks

To first deployment

We move from scoping to a working system in production in weeks. Most engagements ship something usable inside the first month.

## What we build

Concrete systems we ship, tuned to your data and your stack.

### Shared platform layer

Tool layers, identity issuing, tracing, and evaluation built once so the next agent costs a fraction of the last.

### Portfolio operations

The registry, the weekly metrics, and the monthly output sampling that catch quiet degradation before finance does.

### Roadmap sequencing

Which process next, ordered by integration simplicity so early evidence funds the harder work.

### Capability transfer

Your engineers learn the patterns as we go. A partner who is impossible to leave is not a partner.

## How we work

01

### Scope & evals

We pin down what success means and build the evaluation set before writing the feature, so quality is measured, not guessed.

02

### Build in the open

Weekly demos against real data. You see progress every week and can change direction before it gets expensive.

03

### Ship & instrument

We deploy with logging, cost tracking, and guardrails in place, then tune against production traffic.

04

### Hand off or stay

Take the keys with full docs, or keep us on for iteration. Either way you're never locked in.

## Questions, answered

### Why a partner rather than a project?

+

Because the first agent is the expensive one. If you plan to run several, the platform decisions made during the first determine whether the fourth takes six weeks or six months, and those decisions are hard to unwind later.

### What does a partnership look like commercially?

+

Usually a rolling retainer with a defined capacity and a short notice period. We are not interested in a lock-in that outlives the value.

### Will our team be able to take over?

+

That is the intended outcome. We document, pair, and hand over as we go, and plenty of clients bring the work in-house after two or three agents. We would rather be re-hired than retained by default.

### How do you handle changing model providers?

+

Keep the tool layer on MCP and the evaluation sets in your repository, and switching becomes a week rather than a quarter. That is a design choice made at the start, not a migration project later.

## Let's scope your build.

Tell us what you're trying to ship. We'll tell you honestly whether AI is the right tool and what it would take.
