Partnership Models
More Than a Vendor.
Your Growth Partner.
We don't deliver code and move on. From fixed-scope projects to long-term dedicated teams and equity-based co-founding partnerships, Sigma Junction offers engagement models built around trust, transparency, and shared success. Every model is designed so that we win when you win — and not a moment before.
The Sigma Difference
Traditional agency vs Sigma Junction
The agency model was built for a world where software was a cost centre. We operate in a world where it's a competitive advantage — and we structure every engagement accordingly.
| Area | Traditional Agency | Sigma Junction |
|---|---|---|
| Relationship | Transactional — deliver, invoice, disappear | Embedded partner invested in your long-term outcome |
| Communication | Weekly status reports via email or ticket system | Real-time Slack access, async stand-ups, shared roadmap |
| Incentives | Paid by the hour or milestone, outcome irrelevant | Aligned — we succeed only when your product succeeds |
| Technical ownership | Handoff and walk away, no continuity | Ongoing stewardship, proactive refactoring, tech-debt management |
| Team continuity | Rotational engineers unfamiliar with your domain | Dedicated squad that knows your codebase inside-out |
| Strategic input | Scoped to spec — no product or business feedback | Active thought partner on architecture, product, and growth |
Engagement Models
Four ways to work with us
Whether you need a single project delivered or a technical partner for the long haul, there's a model designed for your stage, budget, and ambitions.
Fixed-Scope Projects
You have a clear vision and a defined set of requirements. We execute with precision — on time, on budget, and to spec. Fixed-scope engagements are ideal for discrete features, product launches, or time-boxed builds where predictability matters.
- Detailed discovery & scoping workshop before development begins
- Comprehensive project specification signed off by both parties
- Milestone-based delivery with acceptance criteria at each stage
- Transparent cost breakdown — no surprise invoices
- Post-launch stabilisation period included as standard
- Optional handoff documentation and internal team training
Dedicated Engineering Teams
Scale your engineering capacity without the overhead of hiring. We embed a senior cross-functional squad directly into your workflow — working in your tools, attending your stand-ups, and shipping as a unified team. Scale up or down as your roadmap demands.
- Senior engineers, designers, and QA in a single coordinated unit
- Fully integrated into your sprint cycles and delivery processes
- Monthly team composition review — add or reduce headcount flexibly
- Shared Jira / Linear / Notion — full visibility at all times
- Average ramp time under five business days per engineer
- Dedicated engineering manager accountable to your leadership
Equity Partnerships
For exceptional early-stage startups, we put skin in the game. We provide full-stack engineering capacity — in exchange for equity. This is not outsourcing. We become technical co-founders, sharing your risk and your upside from day one.
- MVP to production-ready product, typically within 10–16 weeks
- CTO-level strategic input on architecture and technical direction
- Equity-based compensation, terms negotiated transparently
- Strictly limited to two to four new equity partners per year
- Requires strong founding team with validated market insight
- Joint quarterly reviews to align on milestones and equity vesting
Technical Advisory
Not every company needs a full build team. Sometimes you need a seasoned technical voice in the room — reviewing decisions, stress-testing architecture, and keeping the organisation honest about engineering health. Our advisory retainer puts senior expertise on-demand.
- Monthly architecture reviews and written recommendations
- Code and infrastructure audits with actionable findings reports
- Fractional CTO representation in board, investor, or executive meetings
- Engineering team assessment and hiring interview support
- Technology stack evaluation and vendor selection guidance
- Incident post-mortems and reliability improvement planning
Business Support Program
We invest in founders
Our Business Support Program is a selective equity partnership initiative for early-stage startups with extraordinary potential. We provide the full engineering firepower of a senior technical team in exchange for a meaningful equity stake — making us true co-founders, not contractors.
This is not a generic accelerator. We do not offer mentorship sessions and a shared desk. We roll up our sleeves, ship production code, architect your infrastructure, and sit in your investor meetings. We accept two to four companies per year. Each one gets our full attention, full capability, and complete commitment.
What we provide
- End-to-end product engineering from concept to production
- Senior full-stack engineers, DevOps, and product designers
- Architecture leadership and technical due diligence support
- Cloud infrastructure design, security, and compliance setup
- Ongoing product iteration guided by user and business data
- Fractional CTO available for board and investor engagements
- Engineering team hiring and onboarding as the company scales
What we look for
- A founding team with genuine domain expertise and market insight
- A problem worth solving — validated by real customer conversations
- Openness to iteration and willingness to challenge assumptions
- A clear monetisation thesis, even if not yet proven
- Alignment on product values and long-term company ambition
- Founders who treat equity as a long-term asset, not a quick exit
- Commitment to building — not just pitching — something meaningful
How the program works
Submit Your Application
Share a short pitch deck, a description of your market opportunity, and a summary of your founding team. We review every submission personally — no automated filters.
Technical & Business Assessment
We conduct a structured two-hour session with your team: part business deep-dive, part technical architecture discussion. We want to understand the problem, the solution, and the people behind both.
Mutual Fit Evaluation
Equity partnerships are long-term commitments. We take a week to assess strategic alignment, market timing, and team chemistry. You are equally encouraged to evaluate us.
Terms Negotiation
We agree on equity percentage, vesting schedule, scope of engineering delivery, and decision-making boundaries. Everything is documented, fair, and designed for long-term trust.
Kick Off the First Sprint
Once terms are signed, we start within days — not months. Sprint zero covers architecture decisions, tooling setup, and the first two-week delivery cycle.
Grow Together
From MVP to scale, we stay at your side. As the product evolves and the team expands, we help you hire, onboard, and gradually transition ownership to your in-house engineering organisation.
Why Choose Us
Built on trust. Sustained by results.
We have turned down more revenue than most agencies will ever see — because the wrong partnership is worse than no partnership. Here is what we are committed to, regardless of the engagement model.
Radical Transparency
No black boxes. You have access to our engineering board, deployment pipelines, and progress metrics at all times. We surface problems early — before they become crises.
Long-Term Thinking
We decline engagements that require cutting corners. Our reputation is built engagement by engagement, and we prioritise durable architecture over quick shortcuts.
Aligned Incentives
Across every model — whether fixed-scope, dedicated, or equity — our commercial structure is designed so that we do better when you do better. Your growth is our growth.
Honest Communication
We tell you when a feature is unnecessary, when a deadline is unrealistic, or when a technical decision will create problems at scale. You deserve a partner who speaks plainly.
Client Success Stories
Results across every model
The companies below represent a cross-section of our engagement models and industries. Details are anonymised at client request.
From zero to $5M ARR in 18 months
A two-person founding team in the B2B payments space approached us with a validated concept and no technical resource. We built the core platform end-to-end — real-time transaction processing, regulatory compliance layer, and a self-serve onboarding flow. The company closed a seed round six months after launch and reached $5M annual recurring revenue within 18 months of first deployment.
Legacy system modernised without a single hour of downtime
A digital health platform serving 400,000 monthly active users needed to migrate from a monolithic PHP codebase to a modern microservices architecture — while keeping the product live and the engineering roadmap moving. Our dedicated squad embedded with their in-house team, executed a phased migration over nine months, and delivered zero-downtime with a measurable improvement in system reliability.
AI-powered feature shipped in six weeks, conversion up 28%
A Series A SaaS company needed to ship an AI-powered recommendation engine before a major industry conference — with a hard six-week deadline. We scoped, built, tested, and deployed the full feature set including model integration, A/B testing infrastructure, and analytics instrumentation. The feature launched on time and drove a 28% increase in trial-to-paid conversion within the first quarter.
The best partnerships happen when incentives are perfectly aligned. When your technology partner earns nothing unless your product earns everything, every architectural decision, every sprint, every late-night debug session — carries genuine purpose.
What founders ask us before signing.
Plain-language answers on equity terms, engagement structure, and how exits work. If your question is not here, ask us directly — we answer all partnership enquiries personally.
A traditional agency optimises for billable hours and scope boundaries. A partnership optimises for the outcome of your business. In practice that means aligned incentives (often including revenue share or equity), long-term commitment to the codebase, and a willingness to push back on bad ideas rather than building whatever is requested.
