Clear models.
No theater.
TriAlpha sells custom engineering — web, mobile, AI, and cloud. Every engagement is scoped with a founder. Indicative ranges below; final pricing depends on complexity and timeline.
How we work together
We don't sell seats or opaque day rates. Pick the model that fits how you buy — then we'll refine a written proposal.
Discovery sprint
From $5,000
A short, focused engagement to clarify scope, architecture, and delivery plan. You leave with a written roadmap, estimate ranges, and a go/no-go recommendation — not a sales deck.
- Stakeholder kickoff
- Technical audit or greenfield plan
- Scope & milestone outline
- Fixed quote for build phase
Fixed-scope project
Typically $25,000 – $150,000+
Best when requirements are clear. We agree on deliverables, timeline, and price up front. Progress is milestone-based with founder-led engineering throughout.
- Defined scope & acceptance criteria
- Milestone payments
- Direct founder involvement
- Staging + production handoff
Monthly retainer
From $8,000 / month
Ongoing product engineering for teams that need steady velocity without hiring. Reserved capacity each month for features, fixes, and infrastructure.
- Dedicated weekly capacity
- Backlog prioritization
- Slack / async collaboration
- Month-to-month after first 3 months
Scope drivers
Platform surface
Web only, native mobile, or a multi-surface product with shared APIs and admin tools.
Integrations & AI
Third-party systems, payments, auth providers, and AI pipelines add design and reliability work.
Timeline & team
Compressed timelines and parallel tracks need more capacity — we price that honestly up front.
