Engagement Model
Four defined phases. Client-controlled gates. An Architecture Lead on every engagement. Here's exactly what you're buying.
Every engagement has a client sign-off gate — you control what proceeds.
Engagement model
Each phase has a defined scope, defined deliverables, and a client gate before the next one starts.

Open-ended consulting produces open-ended uncertainty. We structured the model to eliminate that: defined phases, defined outputs, client-controlled gates. Nothing moves forward without your sign-off.
Scope is defined at each stage based on what the previous stage actually found — not on an estimate made before the work started. You can stop, pause, or redirect at any gate. The work completed to that point is yours, with clear deliverables.
AI tools where they add value. Human judgment where it matters.
Architecture Lead assigned to every engagement.
Same team that designs the system builds it. No handoffs.
Fixed-phase model with defined gates. No open-ended retainers.
India, US, and Europe coverage. Timezone overlap by design.
Everything. All architecture documentation, runbooks, design decision records, and code are client-owned. Kaarastu does not create intellectual property dependencies.
The goal of every engagement is that you can operate, extend, and change the system without us.If your team can't operate independently after the engagement, the handoff isn't complete.
System blueprints
Architecture diagrams, dependency maps, decision records
Runbooks
Operational procedures for every modeled failure mode
Validated code
Implementation with tests, CI/CD pipelines, and documentation
Knowledge transfer
Your team operates independently. No ongoing dependency
The architect who scopes Discovery delivers Architecture. Not a project manager who hands off to a separate team — the same senior engineer from first contact through final Handoff. Continuity means context isn't lost between phases.
No coordination layers. No headcount that generates cost without delivering expertise. The team is assembled for your engagement, sized to the work, and every person on it is there because the problem requires them.
Kaarastu operates on a fixed-phase model. Each phase has a defined scope and a defined cost before work begins — you know exactly what you're paying for before committing to the next stage.
Engagement cost varies based on three factors: the size and complexity of your system, the number of services in scope, and whether the engagement includes an Execution phase. There are no standard tiers because the work isn't standard. Specific pricing is scoped during Discovery, once we understand your system. No scope expansion without your sign-off.
Fixed-phase pricing. Scope, timeline, and cost are defined before work begins.
No open-ended retainers. You approve each phase independently.
Scope document delivered in Discovery. You see exactly what you're paying for before committing.
Your product works, but the system underneath it is starting to resist change. Deployments take longer, repeated incidents. Your best engineers are firefighting instead of building. You've outgrown the architecture that got you here, and adding headcount isn't fixing it.
