the real problem — and how we solve it

Your nightmare scenario

You need engineering capacity. You turn to vendors. Here’s what actually happens.

  • the real problem img

    Locked-in scope

    You define requirements upfront. Your vision evolves. Suddenly you're locked into a contract that doesn't match reality. Change requests? Renegotiations. Conflict. Delays.

  • the real problem img

    Black box delivery in software outsourcing

    You pay. You wait. You have no idea what's actually being built or why decisions are made. You discover problems in month 11, by which time it's too late to fix them.

  • the real problem img

    Hidden costs

    Fixed-price vendors add 30–50% markup to cover "risk." You're paying for their pessimism, not your reality — classic fixed-price development problems. T&M contracts? Budget chaos. Billable hours incentivize slow work, not done work.

  • the real problem img

    Code nobody understands

    You get deliverables. But the team leaves. Now you own unmaintainable code. Post-launch firefighting becomes your new headcount.

  • Talk

    ~30 min

    Schedule a 30-min call. We'll discuss your project, goals, team situation, and which engagement model fit.

  • Audit

    appr 1 week

    If there's a fit, we run a focused product workshop to clarify goals, users, and key flows and shape the initial backlog.

  • Project Kick-off

    next stage

    After the workshop, we either start AI prototyping or kick off the project with an Inception week and a committed team setup.

Engagement Models

Three types of contracts we have

Instead of pretending to predict every detail upfront, JetRuby Flow gives you a framework that provides real control: you see the backlog, watch decisions happen in real time, and adapt scope within your budget.

  • Managed delivery

    You define the goals. We own the execution — team, process, and technical decisions.

    Best for:

    Founders or teams needing an external "engineering arm." You want full risk transfer and guidance on architecture.

    How it works:

    We take on all delivery responsibility. You focus on business. We handle hiring, daily management, and the process.

  • Dedicated team

    You own the strategy and roadmap. We own the day-to-day execution and process.

    Best for:

    Teams with strong internal product leadership who need reliable capacity and technical execution.

    How it works:

    You define priorities and direction. We execute and manage the team. You stay in control; we remove execution overhead.

  • Staff augmentation

    You own everything. We provide skilled specialists.

    Best for:

    Teams with strong internal processes who need specific expertise (ML, DevOps, infrastructure, security).

    How it works:

    You get skilled people. We don't impose process—you decide how to use them.

    JetRuby Flow framework doesn't apply here. This is pure skill-based engagement.

Typical evolution

Many clients start with Managed Delivery (fast, low internal overhead) and evolve to Dedicated Team as internal expertise grows. The same JetRuby Flow process applies; control just shifts.

JetRuby Flow in action

  • Healthcare Compliance Enterprise

    HIPAA platform, 9K+ users, 100% compliance track record

    A healthcare company needed a secure, HIPAA-compliant platform. JetRuby Flow ensured compliance was built in from Week 1, not retrofitted later. Working increments every sprint gave stakeholders immediate confidence. Fixed burn rate freed predictable budget for compliance reviews — no haggling over change requests.

    9,000+ users
    17 companies
    2,500+ monthly growth
    6+ months faster
  • Real Estate PropTech Integrations

    Unit rental platform: from 0 to 20+ facilities in 6 months

    A US real estate developer wanted to turn part of its portfolio into a modern self‑storage business but had no in‑house dev team and several legacy integrations to handle (insurance APIs, StorEDGE, Customer.io). JetRuby Flow gave them a fixed squad, a 2‑week Discovery & Design to align on scope, architecture, and integrations, and a predictable sprint rhythm with fortnightly demos, with the ability to switch from T&M to fixed‑price milestones without losing velocity.

  • Enterprise Legacy modernization AI integration

    80+ legacy apps, 100% on-time over 4 years

    A Fortune 500 company faced 80+ aging IBM/Struts applications. JetRuby Flow won the bid by offering flexible scope within fixed budget — unlike competitors' risky fixed-price proposals. Velocity known by week 4 meant realistic planning from month 1. Disciplined sprints freed time for 80-90% QA automation and AI co-pilot integration.

  • Community platform Real-time systems MVP launch

    Luxury watch community startup: from Facebook group to real-time, multi-platform community in ~5 months

    A 1.7–1.9K‑member watch trading group wanted its own web, iOS, and Android app with Facebook‑like UX, real‑time chat, strict moderation, and zero payment custody. JetRuby Flow provided a 1‑month Inception (FRD, wireframes, reference screen), a 9‑person cross‑functional team, and twice‑weekly demos with CI/CD to lock scope and deliver an MVP with posts, feed, DMs, and ~300‑people group chats, notifications, and role‑based moderation on a ~5‑month plan.

How is JetRuby Flow different from Fixed Price?

Fixed Price locks you into a scope decided upfront (when you know the least). JetRuby Flow locks your budget but lets scope evolve as your vision becomes clearer. You don't overpay for risk markup (30–50% savings), and changes don't require painful renegotiations.

No. JetRuby Flow is designed for independence. Your team owns the codebase and documentation. By month 3 post-launch, you're 95%+ self-sufficient. We stay available for emergency support (fee-based), but you don't depend on us.

AI accelerates routine work (code generation, test automation, monitoring). Humans make architecture and strategy decisions. You see where AI is used and how it affects speed and cost (typically 20–35% faster on repetitive tasks).

Yes. We guarantee 100% team utilization and on-time sprint delivery. If a sprint commitment doesn't ship, we adjust the scope or absorb it. Our goal is outcomes, not hours logged.

Three parts: MSA (Master Service Agreement — sign once, rarely changes), Development Contract (SOW — what we're building), and Payment Terms (weekly/monthly burn rate, billing schedule). Clear boundaries, no surprises.

3 months of included support. Your team owns the codebase. We answer architectural questions and help with knowledge transfer handoff, completeness measured against a checklist (documentation, ADRs, runbooks, ops independence). By month 3, you're independent.

No cost to you. All critical knowledge is pair-programmed (two people know everything). The replacement engineer (from our team) ramps up in 3–5 days due to pairing history and documentation. Your project stays on track.

Weekly or monthly burn rate for your dedicated team (e.g., $30K/week for a team of 5). Multiply by duration. That's your total cost. No hidden fees. No hourly surprises. If sprint velocity changes, cost per week stays the same.

  • Architectural Q&A (async or calls)
  • Bug triage and guidance (not all fixes)
  • Deployment questions and troubleshooting
  • Knowledge transfer pairing (first 4 weeks)
NOT included: Ongoing development, new features, long-term maintenance

100%. All code is yours from day 1. No restrictions. Full IP transfer. JetRuby has read-only access for 12 months (security/compliance questions). You can sell, modify, fork, or open-source it freely.

Schedule a call. We'll discuss your project, goals, and team situation. If there's a fit, we run a 1-week Inception. We mutually audit each other. By the end of week 1, both sides decide: "Let's go" or "Not right now."
