Product Rescue

Stalled product → working release.

Already have code, a prototype, or a half-built app? The job is to get it across the finish line — after a review, not before one.

Tell Us What’s Stuck

Stalled

Incomplete system

  • Half-built screens
  • Missing payments
  • No release path

Review

Engineering intervention

  • Read the codebase
  • Define the finish line
  • Scope the sprint

Shipped

Working release

  • Production build
  • Integrations live
  • Someone can operate it

Business Automation

Need to automate the business instead?

Your team shouldn’t be the integration layer. HPN connects the systems, approvals, data, and repetitive workflows your team still moves by hand.

Typical automation projects $3.5k–$15k+

Explore Business Automation

A workflow, a check, and an exception path — approval stays where judgment is required.

  1. System A
  2. Workflow
  3. Validation
  4. Approval
  5. System B
Manual work puts people, spreadsheets, and inboxes between two systems. The automated path is a workflow with validation, an exception branch, and human approval where it is still required.

Capabilities

Engineering across the product.

  1. 01

    Product Engineering

    Production web applications, SaaS, and the systems that make a product real.
  2. 02

    Mobile Applications

    iOS and Android from one React Native codebase, including completion of stalled apps.
  3. 03

    Backend & APIs

    Spring Boot, Node, PostgreSQL, auth, and the data model the product actually needs.
  4. 04

    Payments & Subscriptions

    Stripe, Connect, billing, and payout flows — not a checkout plugin dropped in late.
  5. 05

    AI Features & Integrations

    Assistants, qualification flows, and AI features wired into a real product, not a demo.
  6. 06

    Cloud & Production Systems

    AWS, deployment, monitoring, and the unglamorous work that keeps a release stable.

Delivery

How the work actually happens.

  1. 01

    Understand the product

    We review what already exists — code, designs, requirements, or a live system — and the outcome you actually need.

  2. 02

    Define the build

    Scope, constraints, and a clear picture of what ships. Work does not start against a vague brief.

  3. 03

    Ship in visible increments

    You see working software as it lands, with progress tied to the agreed scope.

  4. 04

    Launch and stabilize

    Release, fix what production reveals, and leave the product in a state someone can operate.

Full delivery approach

How HPN is run

Direct technical ownership.
Clear communication from brief to code.

You work directly with the engineer responsible for delivery. Scope is defined before kickoff. There is no layer between the brief and the code.

  • Hands-on engineering

    Direct access to the engineer responsible for the build.

  • Project-based delivery

    Fixed-scope engagements. Not a bench of unused hours.

  • Defined before kickoff

    What ships, what it costs, and what is out of scope — written down.

Investment

Typical product project investment.

Final pricing depends on scope and technical requirements.

What affects price

  • Current product state — prototype, inherited repo, or greenfield
  • Feature scope and how many surfaces ship in the first release
  • Integrations: payments, telephony, calendars, third-party APIs
  • Mobile, web, or both
  • Quality of inherited code, if any
  • Launch requirements: stores, production infra, handover

FAQ

Common questions before we start

Straight answers on fit, cost, and how a project actually starts.

What does HPN Studio do?

HPN Studio is a product engineering studio. The primary product work is MVP development, product rescue, and white-label builds for agencies. A separate lane — Business Automation — is for operating businesses that need repetitive workflows connected across existing systems. Mobile, backend, payments, AI, and infrastructure support those engagements.

What do typical projects cost?

Typical project investment is $3.5k–$25k+. Product Rescue usually sits in the $3.5k–$7.5k range. MVP Development is typically $10k–$25k+ for an initial build. Business automation typically ranges from $3.5k–$15k+. Agency partner work is custom quoted. Final pricing depends on scope and technical requirements.

What’s the difference between Product Rescue and MVP Development?

Product Rescue assumes something already exists — a prototype, repo, or unfinished app — and the job is to get it across the finish line. MVP Development is an initial production build from a validated idea, designs, or a serious brief. Rescue is typically $3.5k–$7.5k. Initial MVPs are typically $10k–$25k+.

Do you take on every project?

No. Existing products are reviewed before a rescue is committed. MVPs need a real problem and enough signal to scope a production build. Automation is scoped only when the workflow is actually worth automating. If the work is not a fit, we say so rather than force it into a published price range.

How does a project typically start?

Fill out the project form or email directly. We review what exists — code, designs, a prototype, or a brief — then write a scope and estimate. Work does not start against a vague request.

Do you work with agencies?

Yes. Agency partner work is project delivery: frontend, backend, mobile, payments, integrations, and infrastructure behind the partner’s client relationship. White-label-capable and NDA-friendly. Terms are set per engagement.
