Custom software development services for startups building scalable AI-ready products

Software development services for startups

As a custom software development company for startups, we help you design, build, and scale reliable products — without missed deadlines, black-box delivery, or the technical debt that kills your runway.

From MVPs and prototypes to scaling post-funding products and implementing AI features, NEKLO works as a hands-on technical partner that ships real software and challenges bad assumptions before they become expensive mistakes.

Pre-seed: idea validation & MVP launch

Your priority is proving technical feasibility and market demand without exhausting your initial capital. We act as your de-facto partner, helping non-technical founders with lean MVP scoping. We focus on a high-performance "North Star" product to ensure your technical foundation is robust enough to win early adopters and secure your next funding round.

Seed: velocity, stability & scaling

Here, the pressure shifts from validation to rapid execution. We provide dedicated, senior engineers to clear bottlenecks and refactor early-stage technical debt. This phase is about transitioning from a "move fast" mentality to building a stable, scalable infrastructure that handles increasing traffic with predictable release cycles investors expect.

Series A: industrialization & due diligence

Now, your platform must withstand rigorous technical due diligence and high-volume demand. We focus on industrial-grade architecture, comprehensive documentation, and security compliance so that your product passes investor audits. Our "anti-lock-in" approach includes a seamless knowledge transfer should you choose to move development in-house. You retain full control of your intellectual property.

What usually goes wrong — and how we fix it

The "black box" effect

Traditional outsourcing often leaves founders in the dark, leading to late-stage blockers and missed milestones. We solve this through radical transparency, providing you with direct access to our repository and Jira boards from Day 1. With nightly builds and constant communication, you always know exactly what is shippable and what is blocked.

The "spaghetti code" trap

Cheap, "spaghetti code" might pass a demo, but it collapses under real user load, forcing expensive future rewrites. Our senior-heavy squads (70% senior ratio) enforce clean architecture and rigorous peer reviews. We build professional-grade foundations that support rapid scaling and pass investor due diligence without a performance ceiling.

The "micromanagement" tax

You shouldn't have to chase updates or clarify every single ticket. We provide product-first ownership, where our autonomous squads manage the daily delivery velocity and translate your high-level goals into technical execution. This allows you to focus on fundraising and customer acquisition while we handle the sprint.

The "yes-man" syndrome

Many vendors blindly follow flawed requirements, wasting your runway on features that don't drive growth. We act as technical consultants, not just order-takers. Our team proactively challenges assumptions and suggests technical trade-offs based on your business KPIs, ensuring your budget is always spent on high-impact development.

The "vendor hostage" fear

Founders often worry that moving development in-house will be impossible due to undocumented or proprietary setups. We provide an "anti-lock-in" guarantee: every line of code is fully documented and "transfer-ready." You maintain 100% IP ownership from the first commit, ensuring a seamless handoff to your future internal team.

Premature over-engineering

Burning your runway on complex scalability before validating your core concept can kill a startup. We focus on lean, high-fidelity MVP development, building only what is necessary to reach product-market fit. We ensure your system is "investor-ready" and stable, without wasting capital on edge cases that don't yet exist.
