Shape the product
Translate customer knowledge into a focused product, clear workflows, sensible priorities, and a release plan grounded in what the business needs to learn.
Software development for startups
Turn your market knowledge into production software, then keep improving it as the company learns and grows. Devyou gives you an experienced product engineering team without making you recruit, manage, and become that team yourself.
$5,000 per month. Month to month. One active milestone. You own the software.Onboarding, billing, lifecycle email, analytics, support context, and the product workflow behind them
Built by software founders
We understand the full journey because we live it. Our products serve real customers, process substantial data and traffic, take payments, support daily operations, and keep changing as the businesses mature.

Millions of podcast records, verified contacts, AI-assisted outreach, subscriptions, team workflows, programmatic SEO, documentation, and a public API.

Customer media collection, moderation, product tagging, shoppable galleries, merchant operations, recurring billing, and storefront delivery through traffic peaks.
From first release to a durable software business
The first release starts the learning. Customers expose better opportunities, operational gaps, edge cases, and new demands. We stay responsible as the product and company evolve.
Translate customer knowledge into a focused product, clear workflows, sensible priorities, and a release plan grounded in what the business needs to learn.
Design and ship the smallest complete product that can support real users, real data, and a real business transaction.
Handle deployment, monitoring, backups, incidents, performance, security maintenance, and the infrastructure that keeps the product available.
Use support conversations, analytics, sales insight, and observed behavior to remove friction and strengthen the value customers receive.
Replace repetitive internal work with admin tools, integrations, data pipelines, and reliable background processes as volume grows.
Add plans, permissions, APIs, new markets, programmatic pages, AI capabilities, and larger workflows without weakening the foundation.
Where we join
Custom software development for startups should begin with the current business reality, not a standard package. We can establish the foundation or take accountable ownership of what is already running.
Why Devyou
Modern tools make implementation faster. They do not decide what should be built, protect production data, resolve tradeoffs, or stay accountable when the business depends on the result.
A prototype becomes an unfamiliar codebase. A project agency leaves after delivery. Either way, the founder becomes responsible for regressions, deployments, data, security, and the next release.
YOU BECOME THE ENGINEERING TEAMWe use agentic coding to move quickly, then apply product judgment, architecture, review, testing, production safeguards, and years of operational experience to every milestone.
How the partnership works
You retain the market context and company direction. We own the engineering path from the current priority to a verified production release.
Add ideas, problems, customer feedback, and requests to the private Trello board. Together we choose the highest-value active milestone.
We shape the solution, implement it with agentic speed, review the work, test critical behavior, and deploy a complete improvement.
See the result in production, collect evidence, adjust the roadmap, and move to the next priority without restarting with a new team.
Your private Trello board is the shared source of truth. Async Loom updates show progress and decisions. Calls are available when a decision genuinely benefits from one.
Full product lifecycle
Software product development services for startups must cover the systems that make a feature safe, usable, supportable, and economically useful after it reaches customers.
Clear workflows, durable data models, conventional boundaries, and technical decisions connected to business priorities.
Authentication, roles, access rules, team membership, administration, and safe customer separation.
Checkout, plans, invoices, upgrades, cancellations, failed payments, refunds, and access changes.
Imports, migrations, search, APIs, webhooks, retries, reconciliation, and observable failure handling.
Critical behavior is verified and releases have a deliberate, repeatable path into production.
Errors, failed jobs, slow requests, traffic changes, and unhealthy dependencies become visible.
Production mistakes, bad releases, and infrastructure failures do not permanently erase the company history.
Dependencies, security, support issues, customer learning, and new opportunities are handled continuously.
One ongoing partnership
For startups that need senior technical judgment, continuous output, and accountable ownership without building an internal department yet.
Month to month, plus applicable taxes. One active milestone keeps the team aligned around the most important work.

Questions before we work together
What the service covers, how the relationship works, and what remains yours.
Devyou covers product shaping, architecture, interface design, full-stack development, testing, deployment, monitoring, maintenance, and continuous iteration. We can take a product from an informed idea to a production release, or join an existing application that needs experienced technical ownership.
An MVP engagement concentrates on reaching the first complete release. This service covers the wider startup lifecycle, including what comes before launch and what happens after customers arrive: product decisions, operations, data changes, integrations, reliability, performance, and ongoing development.
Yes. We first understand the codebase, production environment, customer workflows, and current risks. We can stabilize the system, fix urgent constraints, improve delivery, and build new capabilities without treating a rewrite as the automatic answer.
The strongest fit is a founder or domain expert with clear knowledge of a market, customer, or workflow. The product is too specific for a rigid app builder and too important to operate without accountable engineering, but it does not yet require a large internal engineering department.
Devyou costs $5,000 per month, plus applicable taxes and third-party services. The membership is month to month. We work through one active milestone at a time so the team stays focused on the highest-value product or engineering priority.
Coding agents accelerate research, implementation, testing, and routine development. Experienced engineers still make the architecture and product decisions, control context, review changes, verify critical behavior, protect production data, and own every release.
We stay with the product. We monitor production, learn from customers, fix weaknesses, support operational needs, and ship the next priority. The relationship is designed for continuous development rather than a one-time handoff.
You do. The source code, hosting, data, domains, analytics, and third-party accounts remain under your control. If you cancel, you keep everything already built and shipped.
Devyou is not the right model when a startup immediately needs many engineers working in parallel, deep scientific research, hard real-time systems, advanced native mobile specialization, strict enterprise compliance from day one, or around-the-clock operational support.
