Solvios is a software development company for startups building MVPs, full product platforms, mobile applications, AI-integrated features, and the engineering infrastructure that early-stage and growth-stage companies need to move from concept to customers to capital. We work with pre-seed founders building their first product, seed-stage companies scaling past their first thousand users, and Series A companies handling the engineering complexity that comes with product-market fit and investor expectations. Across every stage, the goal is the same: software that moves the company forward without the technical debt that becomes the next fundraising problem.
Minimum viable products built for speed to market without the architectural shortcuts that force a full rebuild at your next funding round — the constraints of an MVP do not have to be the constraints of the product that follows it.
Full-cycle product development from architecture through launch and iteration — covering web, mobile, API, and the data infrastructure that product decisions depend on, delivered in the sprint cadence that startup timelines require.
Products where AI is part of the core value proposition from the first release — not a feature added after the initial build when retrofitting it requires rebuilding the data layer that should have been designed to support it from the start.
iOS, Android, and cross-platform mobile products for startups that need their software in the pocket of every user — built mobile-first rather than adapted from a desktop product that does not translate to a small screen.
Architecture decisions for founders and early engineering teams at the stage where the choices made in the next sprint shape the product's scalability, maintainability, and cost structure for the next three years.

Building software as a startup is a different problem from building software as an established company. The runway is finite. The requirements are uncertain. The architecture decisions made at speed in month two become the scaling problems in month eighteen. The development partner who was right for the MVP is often not right for the growth phase. We have worked with startups across every stage and we know where the real problems are — not the ones that show up in pitch decks but the ones that show up at 2am when the staging environment is down the day before a demo.
The fastest MVP is not always the best MVP. Startups that optimise entirely for speed to demo day end up with a codebase that cannot be shown to a technical due diligence team without embarrassment, cannot be extended without a near-complete rewrite, and cannot handle the user load that a successful launch generates. The architecture decisions skipped in the interest of shipping fast are almost always the ones that create the most expensive problems six months later when the company has users depending on the product and investors watching the metrics.
Most early-stage startups make their first technical architecture decisions with whoever is available, a co-founder who knows Python, a freelancer who knows React, a development agency that builds everything in the framework they happen to be most comfortable with. These decisions compound over time. By the time the company is raising a Series A and interviewing engineering candidates, the codebase reflects the knowledge and preferences of whoever happened to be available at the start rather than the architecture that was right for the product.
The gap between 'what the product needs to do to validate the thesis' and 'what the product needs to do to make every stakeholder happy' is where most startup software projects lose their economics. Scope discipline in a startup MVP is not about building less — it is about being ruthlessly clear on what the first release is actually trying to learn and building only what is necessary to learn it. Development partners who say yes to every feature request without pushing back on whether it belongs in the MVP are not serving the startup's interests.
Most startup founders who have worked with software development agencies describe the same experience: the agency builds what they were asked to build, delivers it on time, invoices correctly, and leaves the founder with software that is technically functional but does not quite solve the problem they were trying to solve — because the agency never pushed back on the spec, never asked why the feature was being built, and never engaged with the business logic behind the requirements. A startup needs a development partner who thinks about the product, not just a vendor who executes on a brief.
Technical debt in a startup does not announce itself during a quiet period. It announces itself during a growth spike when the infrastructure cannot handle the load, during a fundraising process when a technical due diligence reveals problems the team knew about but had been deferring, or during a critical integration when the API design from the MVP does not support what the enterprise customer needs. The startups that avoid this pattern are the ones that made slightly better architecture decisions under time pressure at the start — not the ones that spent more time on the MVP.
Every startup engagement starts with the thesis the product is testing, the timeline the runway allows, and the architecture decisions that will either compound in value or compound in debt. The software is built to validate fast without creating the rebuild that most fast-growing startups hit six months after their best quarter.
Startups are not a single buyer type, they are a spectrum from a founder with a napkin sketch and a Stripe account all the way to a Series B company with 50 engineers and a VP of Engineering. The software needs, the engagement model, and the right development partner are different at every point on that spectrum. We have worked across all of it.

We will map the core thesis your MVP needs to test, identify the architecture decisions that matter now versus later, and give you an honest build plan, before any code is written. Response within 24 hours.

These are not features, they are the capabilities that determine whether a startup software engagement produces a product that validates the thesis, scales with the company, and holds up under investor scrutiny.
Every sprint plan starts with the question the product is designed to answer, not the feature list. We help founders distinguish between what the MVP must do to validate the core assumption and what can wait because scope discipline in the first build is the most important capital efficiency decision a startup makes.
Clean separation of concerns, API-first design, modular feature boundaries, and the code organization that makes a two-engineer team move at the same velocity six months into the build as they did in week one — rather than slowing down as the codebase grows and every change requires understanding a tangled dependency chain.
Data models, service boundaries, and API designs built with AI integration as a first-class consideration — so that when the AI feature is ready to build, the data it depends on is already structured correctly rather than requiring a migration from a schema that was not designed for it.
Cross-platform delivery in React Native and Flutter, native Swift and Kotlin where the use case requires it, and the mobile-specific engineering depth — background processing, push notification infrastructure, in-app purchase mechanics, App Store optimisation — that consumer and B2B mobile products depend on.
Clean, documented, version-controlled codebase, basic security posture, infrastructure-as-code, and the deployment hygiene that survives technical due diligence — because the quality of what a technical reviewer finds during a Series A process shapes the terms of the round.
Weekly progress reports in plain language, honest status on what is blocked and why, direct access to the engineers building the product, and the communication cadence that keeps a founder informed without requiring them to manage a development team on top of everything else they are managing.
Engagement structures that reflect startup economics — not enterprise contract terms applied to a seed-stage company. Milestone-based billing, scope flexibility as the requirements evolve, and the ability to scale the team up or down as the fundraising environment and product priorities change.
Analytics instrumentation, A/B testing infrastructure, feature flag deployment, performance optimisation, and the post-launch engineering work that separates a product that grows from a product that launches and plateaus. Most startup value is created after the first release, not before it.
The startup landscape has shifted: AI is no longer a differentiator that early adopters appreciate, it is a baseline expectation that investors and users bring to every new product. The startups that win in AI-adjacent categories are not the ones who added a ChatGPT integration to an existing product. They are the ones who designed the product around an AI capability from the beginning, where the data architecture, the user experience, and the business model are all built to take advantage of what AI can do rather than retrofitting AI onto a product that was designed without it. Every startup product we build is architected with AI integration as a first-class consideration from the first sprint.

OpenAI, Anthropic Claude, Google Gemini, and open-source LLM integration with the production engineering that generative AI features require — token cost monitoring so the AI feature does not make the unit economics unsustainable, prompt versioning so the output quality does not regress between releases, output validation so the AI does not say something that creates a support ticket or a legal problem, and fallback routing so the feature degrades gracefully when the model API is unavailable. We have seen too many AI startups launch with an impressive demo and a production incident waiting to happen.

Highlights:
Startup software development is not slower enterprise development. It is a different discipline — one where the requirements are uncertain, the runway is finite, and the process needs to produce both working software and validated learning simultaneously. Our startup development process is designed to move fast on the right things and slow down only on the decisions that compound into the most expensive problems if they are made incorrectly.
Here's exactly how it works.
We define what the product is trying to learn from its first users, what the MVP needs to do to generate that learning, and what architecture decisions need to be made correctly from the start. Output is a scoped product brief, a technical architecture recommendation, and a sprint plan that gets working software in front of real users as fast as possible without sacrificing the decisions that compound.
Technical architecture finalized with the iteration speed and AI integration requirements of the product in mind. UI/UX design built for the activation and retention goals of the product — not just for visual appeal. Founder review and sign-off before development begins, because the cost of changing the architecture after the first sprint is an order of magnitude higher than changing it before.
Two-week sprints with working software delivered at the end of each cycle. The core user flow that validates the thesis ships first, not the admin panel, not the settings page, not the feature the co-founder added to the spec last Tuesday. Subsequent sprints layer on the features that the early user feedback justifies building.
Functional testing across target devices and browsers, performance benchmarking against the load the launch is expected to generate, security review, App Store and Play Store pre-submission checks where applicable, and the analytics instrumentation that gives the founder day-one visibility into user behaviour.
Production deployment, launch monitoring, crash triage, and the rapid iteration cycle that responds to what the first cohort of real users actually does versus what the founder expected them to do. The first two weeks of real user data are the most valuable weeks in a startup product's lifecycle — and the process needs to be set up to act on that data quickly.
Feature development based on validated user feedback, performance optimisation as user volume grows, technical debt reduction on a measured timeline, growth engineering — analytics, A/B testing, onboarding optimisation — and the ongoing product evolution that turns a validated MVP into a product that scales with the company.
Startup software engagements cannot be structured like enterprise contracts. The scope changes as users give feedback. The timeline compresses when a funding round closes or expands when it does not. The team size needs to flex with the product priorities. We structure startup engagements around the realities of startup economics rather than around what works for the vendor.
You have secured funding, your product thesis is validated, and you need to scale development faster than you can hire or you need a full-stack product team from the beginning because you do not have a technical co-founder and the product is the company.
Hand-picked engineers, a QA specialist, and a technical lead working exclusively on your product. Sprint planning, standups, and demos run on your calendar. AI integration, mobile development, and growth engineering are all handled in-house. The team thinks about the product, not just the backlog.
Monthly retainer. No surprise invoices. Team composition flexes up when you close a funding round and down when the roadmap is between major phases. Minimum team size is two engineers.
2–8 engineers
3-month minimum
Scales with 30-day notice
There are hundreds of development shops that will build your startup's MVP. Most of them will do it on time, bill you correctly, and hand over a codebase that works but that you will spend the next twelve months explaining to the engineers you hire after them. Here is what makes the difference in practice.
We Push Back Before We Build
The most valuable thing a startup development partner can do is challenge the scope before agreeing to the timeline. We ask why a feature is in the MVP before we estimate how long it will take to build. We flag when a requirement implies an architecture decision that will be expensive to change later. We tell founders when the v1 they are describing will take six months when they have four months of runway. That conversation is uncomfortable and it is the most important one we have.
Architecture Decisions That Compound in the Right Direction
We make the architecture decisions that matter: data model design, API contract design, service boundaries, authentication architecture carefully and explicitly, because these are the decisions that compound either in your favour or against you as the product grows. Everything else we do at startup speed. The thirty minutes we spend on the data model before the first sprint saves thirty days of migration work after the Series A.
AI-Integrated from the First Sprint
AI is not a feature we add to startup products when a founder asks for it. It is an architectural consideration we address in the discovery phase because the data models, service boundaries, and API designs that support AI features need to be built correctly from the start. We have built AI-integrated products across multiple verticals and we know where AI creates genuine user value versus where it creates impressive demos that real users do not actually use.
We Have Built Products Across Every Startup Archetype
Two-sided marketplaces, fintech products, on-demand services, B2B SaaS, consumer mobile apps, developer tools, AI-native products, the case studies on this page represent real products built for founders with real theses. We bring that cross-vertical experience into every startup engagement because startup problems recur across verticals: the marketplace chicken-and-egg problem, the SaaS onboarding activation gap, the AI cost curve that makes the unit economics unsustainable at scale.
Transparent, Honest, Available
Direct access to the engineers building your product. Weekly progress reports in plain language that a non-technical founder can act on. Honest status on what is blocked, what will slip, and what needs a decision from you before the sprint ends. We do not manage founders with optimistic status updates that turn into surprises at launch. The goal is for you to know as much about your product's development as we do.
US-Based Communication, Startup-Calibrated Cost
Project management and client communication on US business hours. The commercial model reflects the economic reality of building a startup — not enterprise contract terms applied to a seed-stage company. We have worked with founders who are counting every dollar and founders who have just closed a Series A, and the engagement model adapts to where you are in the capital cycle.

Honest answers to the questions every founder asks before choosing a startup software development company. If something is not covered here, our team will walk you through it on a discovery call, no sales pitch, no fluff.
focused MVP with core user flows, basic backend, and a web or mobile interface typically starts at $20,000–$60,000 depending on complexity. A mid-complexity product with multiple user roles, third-party integrations, and a mobile app ranges from $60,000 to $150,000. A full-featured SaaS or marketplace product with AI features, complex data architecture, and multiple platforms is typically $150,000–$400,000. For bootstrapped founders, we can work within tighter budgets by scoping the MVP rigorously around the specific thesis the first version needs to validate. We provide detailed estimates after a discovery session. We will not give you a number we cannot stand behind.
tightly scoped MVP with a single core user flow, basic backend, and web interface can be delivered in 6–10 weeks. A standard MVP covering the main user journey, third-party integrations, and a mobile app takes 10–16 weeks. A complex MVP with AI features, multiple user roles, and a marketplace architecture takes 16–24 weeks. The most important variable is scope discipline, every feature added to the MVP brief adds time, and most of what gets added to a startup MVP spec in the weeks before development starts is not in the original MVP for a good reason.
It depends on the product, the founder's existing technical context, and the hiring market for the technology. For most web MVPs: React or Next.js on the frontend, Node.js or Python on the backend, PostgreSQL or MongoDB for the database, AWS or Vercel for hosting. For mobile: React Native or Flutter for cross-platform, Swift or Kotlin for native when the use case demands it. For AI-integrated products: OpenAI or Anthropic APIs for LLM features, Python for ML workloads, LangChain for agent workflows where applicable. We make technology recommendations based on the product, not based on what our team happens to be most comfortable with and we explain the trade-offs honestly.
For most early-stage startups, a development agency is faster to start, lower risk on a per-dollar basis, and more flexible as the product requirements change than an in-house team hired before the thesis is validated. The calculus changes after product-market fit when you have enough clarity to hire senior engineers for roles you can define precisely and enough stability to justify the hiring overhead. Most founders who work with Solvios start as agency clients and transition to a hybrid model keeping Solvios for specific workstreams while building their in-house team around the product areas that are most certain.
A good startup development partner pushes back on scope before agreeing to timelines, asks why a feature is in the MVP before estimating how long it takes to build, makes architecture decisions explicitly rather than implicitly, communicates honestly when something is blocked or will slip, and thinks about the business problem rather than just the technical brief. The most important question to ask a prospective development partner is not about their tech stack or their process. It is: tell me about a time you told a founder their MVP spec was wrong. If they cannot answer that question with a real story, they are not the right partner for a startup.
Pivots are expected in startup product development, the process should be designed for them, not surprised by them. On the commercial side, Time and Material engagements handle pivots naturally because the billing is against actual work rather than a fixed scope. On the technical side, we design MVPs with modular service boundaries and clean API contracts that make pivots cheaper than they would be in a tightly coupled architecture. We have managed through product pivots on multiple engagements and the difference in pivot cost between a well-architected MVP and a poorly architected one is typically measured in months, not days.
Yes. AI-integrated product development is one of our specific capabilities for startups. We integrate OpenAI, Anthropic Claude, Google Gemini, and open-source models with the production engineering that AI features require in a real product cost monitoring, prompt versioning, output validation, fallback routing, and the evaluation infrastructure that measures whether the AI is actually doing what the product claims. We also help founders assess honestly where AI creates genuine user value in the product versus where it creates an impressive demo that real users do not actually use because these are not always the same thing.
Three models: Dedicated Startup Team for funded startups that need a full product engineering unit working exclusively on their product; Time and Material for iterative development where the product direction is still evolving based on user feedback which is most startups, most of the time; and Fixed Cost for well-scoped MVP builds where the user flows and technical requirements are clearly documented before development begins. We recommend the right model based on where you are in the fundraising cycle and how much certainty you have in the product scope.
