A solo US software studio for tech teams who want real ship dates, clean code they own, and an operator on the build — not an account manager forwarding the project to a contractor.
Each product below was built end-to-end on the same in-house stack we'd use for your build — Node, Next.js, Postgres, Stripe, OpenAI & Anthropic. No subcontractors, no agency layers. The work below is what holds your build's bar.
Branded coaching app for personal trainers. Programs, Stripe-billed memberships, AI-generated training plans with per-client memory, daily check-ins. Live in 24 hours from intake under each coach's own brand.
Manual-first personal command center for high-net-worth solo operators. Tax Brain (wash-sale, harvest, RMD, QSBS, AMT scans), Monte Carlo cash-flow forecast, AI specialist trained on tax code, encrypted document vault — all without aggregators or Plaid.
Eight strategy frameworks, Notion templates, and 20+ AI advisor prompts that run HELM — packaged for self-directed investors. The same prompt library and Tax Brain logic we use in production, made portable.
Three formats, fixed price each. Pick the one that matches the size of the problem; we scope honestly and tell you up front if we can't deliver in the time we quote.
Copy & design refreshes. New sections or pages. Performance fixes. Brand reskins. A/B test setup. Bug fixes on someone else's old code. Fast turn, no retainer.
Full marketing sites. Single-product landing pages. SaaS waitlist & launch pages. Comparison and competitor pages. Brand rebuilds. Conversion-optimized, performant, SEO-clean.
Custom web apps. Internal dashboards & admin tools. Customer portals. Full SaaS MVPs. AI features into existing products (RAG, agent flows, embedded copilots). Stripe, auth, Postgres — production-grade.
The reasons the work goes fast without sacrificing polish — and the reasons it survives handoff cleanly when you take it in-house.
One async intake, one short kickoff call, then the work. No 40-page proposals, no weekly status meetings that produce nothing. We send you the actual build.
You get a number before we start, and we hold to it. If the scope grows we tell you what it'd cost up front — no surprise change orders, no hourly creep.
About ten business days for a custom site, two to three weeks for an app, three to five for a platform. We tell you the date on day one and we hit it. If we can't deliver in the time we quoted, we say so before you commit.
GitHub repo transferred on day one. No license fees, no platform lock-in, no proprietary CMS you can't move off of. The code is yours; we just built it for you.
When you hire Vantage Digital, you get the person doing the work — not a coordinator passing your project to a subcontractor.
Led by an operator with years inside high-performing SaaS and tech-product teams. Production software shipped to real users, on the same modern stack we'd use for your build — Node, Next.js, Postgres, Stripe, modern AI APIs.
AI tooling is part of how the work gets built — RAG, agent flows, embedded copilots, prompt-engineered specialist tools, AI-assisted dashboards. Not a "we use ChatGPT" badge. You'll see the difference in what gets shipped.
The bar is what the shipped products demonstrate — fast, polished, brand-consistent, monetized through Stripe, used by real customers. Your build holds to that standard whether it's a $500 landing page or a $25K SaaS MVP.
