Work With Us

Our Story

zx web was founded in 2024 by two professionals who recognized a critical gap in the consulting market: businesses needed senior-level technical expertise combined with genuine understanding of business objectives and investor expectations—without the overhead of large consulting firms or the unpredictability of typical freelance arrangements.

We started as a focused operation with a clear philosophy: deliver excellent engineering work with transparent communication, practical solutions, and an understanding of what actually matters to business success. No sales pitches, no unnecessary complexity—just experienced developers who understand both code and business building real solutions.

Today, we serve startups building their first MVPs, growing companies scaling their systems, and established businesses modernizing legacy infrastructure. Every project receives hands-on attention from our founding team, ensuring both technical excellence and business-aligned outcomes.

Role at zx web

Manages all client relationships, business development, and strategic consulting. Ensures technical solutions align with business objectives and can articulate value to both technical and business stakeholders.

Philosophy

Technology should serve business objectives and demonstrate clear ROI. Having seen the investor side of startups, understands what makes technical decisions defensible to stakeholders and how to communicate technical trade-offs in business terms.

Our Approach to Engineering

Founder-Led Delivery

Unlike larger consultancies where senior staff handle sales then delegate to junior developers, we remain hands-on throughout every engagement. You work directly with experienced engineers who make technical decisions and write production code.

Scalable Team Model

For projects requiring specialized expertise beyond our core competencies, we collaborate with a trusted network of professionals. We handle vetting, coordination, and quality assurance—you get expanded capabilities without managing multiple vendors.

Transparent Communication

We provide honest assessments even when it means recommending against additional work. If an off-the-shelf solution makes more sense than custom development, we'll tell you. If your timeline is unrealistic, we'll explain why and provide alternatives.

Knowledge Transfer Priority

Every engagement includes documentation, code comments, and knowledge transfer sessions. We want your team to be self-sufficient after we leave. Our success is measured by your team's increased capability, not continued dependency.

Practical Technology Choices

We favor proven technologies and established patterns over experimental frameworks. Our stack choices prioritize long-term maintainability, hiring ease, and community support. We'll gladly explain tradeoffs between different technical approaches.

Business-Aligned Technology

With investor experience on the team, we understand how technical decisions impact business value, fundraising, and stakeholder confidence. We make technology choices that are defensible to investors and aligned with business growth.

Our Values

Code Quality Over Speed

We prioritize maintainable, well-tested code that your team can work with long-term. Fast delivery means nothing if the system becomes unmaintainable within months.

Honest Technical Assessment

We provide realistic timelines and capabilities assessment, even if it means acknowledging limitations. Technical honesty builds better long-term relationships than overpromising.

Client Capability Building

Our goal is to make ourselves unnecessary. We document thoroughly, explain our decisions, and train your team so they can maintain and extend systems independently.

Investor-Ready Thinking

We understand what investors look for in technical due diligence. Our solutions and recommendations consider how technical decisions will be evaluated by potential investors, acquirers, or board members.

Why Choose zx web?

Technical + Business Perspective: Unlike pure engineering consultancies, we bring both technical execution and business strategy thinking. Our team includes investor experience, ensuring technical decisions align with business objectives and stakeholder expectations.

Lower Overhead, Better Value: We don't have layers of management, large sales teams, or expensive offices. Our rates reflect actual engineering work and strategic guidance, not corporate infrastructure costs.

Direct Access to Decision Makers: When you have a question or concern, you reach the people actually writing code and making strategic decisions. No account managers or project coordinators acting as intermediaries.

Flexible Engagement Models: We adapt to your needs rather than forcing projects into standardized packages. Whether you need a week of consulting, three months of development, or ongoing technical advisory—we structure engagements around your requirements.

Realistic Scope and Timelines: Small teams can't hide behind organizational complexity. We provide honest assessments of what's achievable within budget and timeline constraints because our reputation depends on delivering what we promise.

Long-Term Relationship Focus: We build reputation through referrals and repeat clients, not through high-volume sales pipelines. Your success directly impacts our growth, aligning incentives naturally.
