Startup Tech Advisory & MVP Building
From idea to shipped.
Technical leadership
for startups that
move fast.
Callisto Studio partners with early-stage founders to architect, build, and ship products. From the first line of code to the first customer.
What we do
Technical leadership, from day one.
Strategic CTO advisory for founders who need senior engineering judgment without the full-time hire. We help you set technical direction, structure your first engineering team, make the right architectural decisions early, and avoid the expensive mistakes that derail products before they ship.
From idea to shipped product.
End-to-end ownership of your MVP build — architecture, engineering, and deployment. We've launched ventures from scratch across AdTech, Education, Web3, and developer tooling. We know what to build first, what to skip entirely, and how to get something real into users' hands fast.
Simple by design
Discovery
We talk through your idea, where you are, and what's blocking you. We'll tell you honestly what we think, what we'd prioritise, and whether we're the right fit.
Proposal
A clear engagement structure — scope, timeline, what we own. No retainer padding, no ambiguity.
Engagement
Hands-on from day one. Weekly advisory, embedded engineering, or both — we stay close to the work until it ships.
Built on real experience
Callisto Studio is a technical advisory and product development studio founded by a hands-on CTO with 16+ years of experience building full-stack, scalable systems.
We’ve launched four founder-led ventures from zero to market, across AdTech, Education, Web3, and developer tooling.
We bring the same depth of technical execution to every engagement. Whether that’s shaping your architecture in week one or shipping your MVP in month three.
