Capabilities
Three groups of capability: intelligence, product engineering and growth. Most clients start with one and add the others as the product grows. Nikola Golux leads every engagement, with named collaborators, so the context stays the same.
Not sure which you need? If something specific is broken in an AI-built app, start there instead. The free audit names it, and one fixed-price fix is often the whole answer.
01: Intelligence
AI that is grounded in your own information, and the data platform that makes grounding possible. These two travel together: an assistant is only as good as the knowledge layer beneath it.
Generative AI, AI agents and multi-agent systems built on your data
Reliable pipelines, organized data, AI-ready knowledge
02: Product engineering
Architecture, backend systems, web interfaces, UX and UI design, and an honest answer on mobile. Everything needed to take an idea to something people use every day, and can keep using at scale.
Systems that stay predictable as volume grows
Fast, accessible interfaces on real devices
Web-first, with a mobile app when the product earns one
Interfaces designed around the decision your user is making
03: Growth
Technical SEO, analytics and content architecture built into the product, so every release compounds visibility. When positioning is the real constraint, marketing strategy comes first.
Focused services
Each of these has its own page with the scope, what it costs and when it is the wrong thing to buy.
Agents that use your tools and data, inside limits you set, asking a person before anything risky.
ExploreDiscovery, an outcome-based roadmap, priorities and specs.
ExploreResearch, flows, interface design and a design system in code.
ExploreBuild, buy or stop decisions, a risk register with owners, AI governance.
ExploreA mark, color and type that hold up in a product, delivered as tokens.
ExplorePositioning, channels and a dated calendar, with execution if you want it.
ExploreHow we work together
The capability answers what gets built. The arrangement answers how the work is organized, who leads it and how you pay for it. Terms are agreed on the call. Moving between tiers is an email.
Advisory, fractional CTO or embedded hours with a stated monthly cap.
Advisory at $2,500 a month (6 hours), fractional CTO at $6,000 (16 hours and a weekly call), or embedded at $12,000 (36 hours). Hours are stated on every tier.
Best for: decisions that need a senior owner every month
Fractional CTOOne scoped piece of work, priced in writing after the call.
One scoped piece of work at $300–400 an hour, 10 hours minimum, priced in writing after the call. Handed over documented, so any team can extend it.
Best for: a clear brief with a deadline
Product & system designProduct, design and engineering as one arrangement, one company at a time.
Product, design and engineering as one arrangement at $20,000 a month (60 hours), under one accountable person. One company at a time.
Best for: a funded company with no technical side yet
Startup partnerDelivery
Agree the problem, the constraints and the metric that will move.
The smallest architecture that solves it, written down before code.
Two-week increments with something reviewable at the end of each.
Monitoring, iteration and a handover your engineers can carry.

You will speak to an engineer, not a sales team. We typically reply within 48 hours.
The engineering notes
The findings from the apps we audit, the fixes that worked, and what each one cost, written by the person who did the work. No roundups, no reposts.
