Know Exactly What You Are Building Before You Start
Structured technical discovery that gives you architecture design, technology recommendations, effort estimates, and a delivery roadmap you can trust. The right foundation for every decision that follows -- whether you build with us or someone else. Two weeks, fixed price, no commitment beyond.
Sound familiar?
The Discovery Gap
You do not know where to start technically.
You have a validated business idea, perhaps some wireframes or a clickable prototype. But the technical side is a blank page. Every advisor you talk to has a different opinion. You need an independent, evidence-based assessment from someone whose only agenda is getting the architecture right.
You have been given wildly varying estimates.
One agency says three months and 50k. Another says six months and 200k. A freelancer says two weeks and 5k. The variance is enormous and you have no way to judge which estimate is credible. You need an honest, detailed breakdown that explains what drives the cost and timeline.
You are worried about making the wrong technology choices.
React or Vue? AWS or Azure? PostgreSQL or MongoDB? These decisions have consequences that compound over years. You want to make these decisions once, make them well, and have confidence that someone experienced has thought through the implications for your specific product.
The Source Stream difference
Clarity Before Commitment
Structured discovery process
We follow a rigorous discovery methodology refined across dozens of startup engagements. Stakeholder interviews, user journey mapping, feature prioritisation, technical constraint analysis, and architecture design -- all compressed into a focused two-week engagement.
Architecture designed for your trajectory
We design architecture that is right-sized for your next twelve months, with clear extension points for growth beyond that. We document the decisions we made, the decisions we deliberately deferred, and the trigger points for revisiting them.
A roadmap you can actually use
A practical delivery roadmap with realistic effort estimates, milestone definitions, technology recommendations with clear rationale, and a risk assessment. You can take this roadmap to any development team and they can start building from it.
Deliverables
What You Get
Technical architecture document
System design covering application structure, data models, API design, integration points, authentication approach, and deployment strategy.
System design diagrams
Visual representations of the architecture, data flows, component relationships, and infrastructure topology.
Technology recommendations
Stack selection with clear rationale, considering your product requirements, team plans, hiring market, and growth trajectory.
Feature prioritisation matrix
Every feature assessed against user value, technical complexity, strategic importance, risk, and dependencies.
Effort estimates
Realistic, phase-by-phase estimates for the full build, broken down by milestone with assumptions and risks documented.
Delivery roadmap
Week-by-week plan showing what gets built when, with dependencies, decision points, and resource requirements.
Risk assessment
Honest identification of technical risks, external dependencies, integration unknowns, and potential blockers with mitigation strategies.
Our process
How It Works
Stakeholder Interviews
Week 1We meet with you and your team to understand the business model, target users, competitive landscape, funding situation, and existing constraints. We also speak with technical advisors and domain experts.
Technical Analysis
Week 1-2Our architects evaluate technology options, assess third-party integrations, and identify the key technical decisions that will shape the build. We research the technology landscape specific to your domain.
Architecture Design
Week 2We design the system architecture, select the technology stack, model the data layer, define the API structure, and plan the deployment strategy. Every decision is documented with rationale.
Roadmap Delivery
Week 2We present the complete discovery output and walk you through every decision. The output is yours to keep and use regardless of what you decide to do next.
