Every Stack18 engagement runs on the Agentic SDLC, where ten specialised AI agents work alongside our senior people.
| Traditional agency | Stack18 | |
|---|---|---|
| Delivery model | People do every task by hand | Senior people lead, AI agents execute behind approval gates |
| Visibility | Status reports and surprises | Working software and live progress every week |
| Documentation | Written at the end, if at all | Generated and kept current as the work happens |
| Knowledge | Leaves when people do | Captured in a connected software graph |
| Pricing | Time and materials, open-ended | Fixed-price first step, then fixed scope or a monthly team |

How do engagements usually start?
With a free consultation, then a short, fixed-price first step such as a discovery sprint or assessment. You see the plan and the team before committing to more.
How do you price services?
Fixed price for defined scope, or a transparent monthly cost for a dedicated team. You get an indicative estimate after the first call.
What does AI-native delivery mean for us?
Your project runs on the Agentic SDLC. AI agents draft specs, code, tests and documentation, and senior people review and approve. You get more working software, sooner, with full traceability.
Do you work with companies outside India?
Yes. We work with teams in India and abroad, across time zones, with English as the working language.
Should we choose services, a solution or the Enterprise Pod?
Choose a solution when a ready-made system fits, services when you need something built or changed, and the Enterprise Pod when you want one team for a multi-year transformation. We will tell you honestly which fits.

A senior architect will reply within one business day with next steps and, after a short call, an indicative estimate.
