16.04.18 is a Tallinn-based product studio that designs and builds two-sided marketplaces — payments, matching, trust and search — for founders and companies. We ship a working, scalable marketplace fast, built to grow.
We design supply and demand together — onboarding, listings, search and matching — so both sides of your marketplace actually work.
Secure checkout, split payments, escrow and seller payouts wired in with proven providers, not reinvented.
Ratings, reviews, verification and moderation that make strangers comfortable transacting with each other.
Fast, filterable search and discovery so buyers find the right supply and sellers get seen.
Clean architecture and a modern stack ready for liquidity, geographies and new categories.
For marketplace startups we believe in, we co-build the MVP in exchange for a share of the company.
We define the smallest marketplace that proves liquidity is possible, with a clear plan, timeline and budget.
Flows for both sides — onboarding, listing, discovery, checkout — designed to feel finished.
Weekly progress you can test, with payments, trust and search built in from the start.
We ship to real buyers and sellers, measure liquidity, and iterate toward a healthy, growing marketplace.
Building a two-sided marketplace is not hard because of the software; it is hard because an empty marketplace is worthless to both sides. The build has to make early liquidity possible: narrow the first category, seed supply manually, and design matching so the very first buyer has a good experience with only a handful of sellers.
We design the product around that cold-start reality instead of shipping a generic listings site and hoping.
Under the surface, marketplaces share the same demanding building blocks — and each one has legal and financial consequences if it is done badly.
Your monetisation model changes the product, not just the pricing page. Commission requires you to keep transactions on-platform; subscriptions require ongoing value for supply; lead fees require attribution. We help you pick one before we build, because retrofitting the wrong model is a rewrite of the money path.
We quote per phase after a scoping call. These factors move the number up or down.
We fix the phase scope in writing, keep a visible backlog, and take new ideas into the next phase instead of stretching the current one.
We define what success means before the build, ship in weekly increments and adjust from real usage rather than assumptions.
Your company owns the repositories, infrastructure and accounts. We document the architecture and can hand the codebase to your own team at any phase boundary.
Store reviews, third-party approvals and content dependencies are tracked as explicit dates in the plan, not assumed away.
Marketplace development services design and build platforms that connect two or more groups — buyers and sellers, clients and providers — with the listings, search, payments, payouts and trust features they need to transact safely at scale.
A focused marketplace MVP typically launches in a matter of weeks. After a short discovery call we give you a concrete timeline and fixed scope.
We design the launch around one narrow segment where supply and demand can meet quickly, rather than trying to fill the whole market at once — then expand from that first liquid niche.

Yes. For marketplace startups we genuinely believe in, we co-found and build the MVP in exchange for a share of the company.
