How we work: Agile methodology & sprint framework
We eliminate the risks of traditional waterfall agency contracts by building your product in rapid, transparent 2-week agile sprints. You get continuous visibility, weekly staging demos, and the flexibility to adapt priorities as your vision evolves.
2-Week Sprint Cadence
Work is broken into predictable 14-day sprint cycles with defined story points, clear acceptance criteria, and transparent milestone commitments.
Free First Wireframe (Sprint 0)
We de-risk your investment by delivering your initial wireframe and architecture roadmap for free before any long-term contract is signed.
Live Staging & Weekly Demos
You test real, working software every week on a private staging link. No static slide decks — see actual progress in real time.
Adaptive Scope Flexibility
Market conditions change. Re-prioritize your product backlog at the start of any sprint without painful change orders or penalties.
Direct Engineer Access
Collaborate directly with your dedicated Scrum Master and engineers in a shared Slack or Teams channel. Zero middlemen, zero miscommunication.
100% Code & IP Ownership
Every commit belongs to you. Complete Git repository, documentation, deployment scripts, and credentials handed over at milestone completion.
The 14-Day Sprint Lifecycle
1. Sprint Planning
User stories groomed, acceptance criteria locked, story point commitments agreed.
2. Focused Build
Daily async standups, test-driven code execution, continuous integration to dev branches.
3. Demo & QA
Live walkthrough on private staging URL, client feedback incorporated directly.
4. Release & Retro
Milestone pushed to staging/production, sprint retrospective held, next sprint planned.

How much does custom software development cost?
Custom software cost depends on the number of features and user roles, integrations with other systems, and data or security requirements. An MVP with a focused feature set is a fraction of the cost of a full platform.
We break work into milestones with a fixed price each, so you can launch a first version, measure results and decide on the next phase with real data.
Key factors that affect investment
- ✓Features and user roles
- ✓Integrations with existing systems
- ✓Data migration
- ✓Security and compliance needs
- ✓Cloud hosting and scale
- ✓Ongoing support and development

Frequently asked questions
Everything you need to know about our sprints, timeline, code handoff, and support.
[01]What is custom software development?+
Designing and building software for your specific business or product — such as a SaaS platform, internal tool or customer portal — instead of adapting an off-the-shelf product.
[02]How much does custom software development cost in India?+
It depends on features, integrations and scale. We scope a focused first version and price each milestone separately, so you only commit to what you need now.
[03]Do you build MVPs for startups?+
Yes. We help founders define a focused MVP, build it in weeks rather than months, and keep developing it as the product finds traction.
[04]Which technologies do you use?+
Mostly TypeScript, React, Next.js and Node.js with PostgreSQL or Supabase, hosted on AWS or Vercel — plus LLM APIs for AI features where useful.
[05]Can you work with our existing systems?+
Yes. We integrate with CRMs, ERPs, payment providers and internal databases, and can modernise legacy systems gradually.
[06]Will we own the source code?+
Yes. You receive full ownership of the source code, infrastructure accounts and documentation.
