ABOUT US
Who We Are
LunaInvent is a strategic technical consultancy providing calm, senior leadership for teams building real products.
We work with digital agencies, startups, and small companies navigating complex technical decisions — from early architecture and delivery design to modernisation and scaling. Our focus is on clarity, sound judgement, and decisions that hold up over time.
How We Work
OUR SERVICES
What We Do
Strategic Technical Leadership
Senior technical direction during critical phases, helping leaders make confident decisions without unnecessary overhead.
Architecture & Platform Planning
Pragmatic architecture guidance covering system design, trade-offs, and evolution paths that stand up as products grow.
Delivery Design & Enablement
Ways of working, technical guardrails, and mentoring that improve flow and quality without slowing teams down.
Modernisation & Scaling
Reducing complexity and technical debt while improving reliability, performance, and change-safety over time.
Advisory & Decision Support
Objective input for high-impact decisions, reviews, and planning sessions where clarity matters more than speed.
Fractional CTO Engagements
Ongoing, flexible technical leadership providing continuity and confidence without a full-time hire.
HOW WE WORK
A clear path from uncertainty to action
A lightweight approach designed to create clarity quickly — then support delivery where it matters.
Our Approach
Understand the context
We get up to speed on goals, constraints, systems, and delivery realities so we’re solving the right problem.
Clarify the decision
We identify the real decision points, trade-offs, and risks, cutting through assumptions and noise.
Design the path forward
We define a pragmatic plan: architecture direction where needed, sequencing, and clear guardrails.
Support delivery
We stay involved at the right level through reviews, decision support, and course-correction as reality changes.
Engagements can be advisory, architecture-led, or fractional CTO — depending on what you need.
WHO WE WORK WITH
Teams that value clarity over noise
We support organisations where technical decisions carry real consequences — and getting them right matters.
Digital Agencies
Agencies needing senior technical leadership to support delivery, unblock decisions, and strengthen architecture — without growing permanent headcount.
Startups
Founders and early teams navigating architecture, scaling, or critical delivery moments where the wrong decision compounds quickly.
Small & Growing Companies
Teams modernising platforms, improving delivery confidence, or regaining control of systems that have grown faster than their foundations.
Engagements are shaped around your context — advisory, architecture-led, or fractional CTO support as needed.
OUTCOMES
What changes when we work together
Practical outcomes that reduce delivery risk, improve confidence, and keep technical decisions stable as you scale.
Clear technical direction
Decisions stop bouncing around and move forward with clarity and confidence.
Reduced delivery risk
Trade-offs, constraints, and risks become visible early — before they cost time.
Pragmatic architecture
A structure that supports change without unnecessary complexity or rework.
Stronger team alignment
Product, engineering, and leadership move in the same direction with fewer surprises.
Cleaner execution
Guardrails and reviews that raise quality without slowing delivery.
Momentum with control
A plan that’s actionable now, with space to adapt as reality evolves.
Typical outputs include architecture notes, decision records, delivery guardrails, and a clear next-steps plan.

Sebastian Siek
Founder & Technical Advisor
I specialise in providing senior technical leadership for teams navigating complex product and platform decisions - particularly where architecture, delivery pressure, and long‑term scalability intersect.
I founded LunaInvent to offer experienced, hands‑on technical guidance without the overhead or rigidity of traditional consultancies. The focus is on clear thinking, pragmatic architecture, and decision‑making that holds up under real delivery constraints.
