Marketplaces and platforms that bring both sides together.
PageSimple designs and builds custom marketplaces and platforms: two-sided marketplaces, matching and booking platforms, directories and member portals, with sign-up, payments and the admin tools to run them. Each project is one fixed price for a fixed scope, and you own the code.
Custom web applications, designed, built and deployed by PageSimple, then kept running after launch:
Two-sided marketplaces
Clients and providers, buyers and sellers, founders and experts: both sides sign up, get matched and do business in one place. Infinia, below, is one.
Booking and matching platforms
People find the right provider and book them, with availability, reminders and payment handled in the same flow.
Directories and listings
Searchable listings that members pay to join or to be featured in, with profiles they manage themselves.
Member and subscription portals
Content, communities or tools behind a login, with recurring billing.
Built and running
A real project in this category: the problem, what was built, and how it works today.
Web application · Fractional executive marketplace
Infinia
A marketplace that introduces growing businesses to vetted fractional CFOs, COOs, CROs, CMOs and CTOs.
The problem
Founders need part-time senior leadership without a long search, and fractional executives want a steady flow of qualified introductions. Infinia needed a fair, explainable way to decide who meets whom.
What we built
A public site where founders describe their challenge and executives apply, a portal where executives set their criteria, fund a balance through Stripe and set a max bid, and a staff desk to vet leads and watch every match live.
The outcome
Each introduction is decided by an automatic auction and recorded with the reason it was won. Staff can explain any match, and executives can see what a higher bid would have bought them.
Each side signs up its own way, and where trust matters, new members are vetted before they go live.
Matching people can understand
Search, rules or an auction, both sides can see why a match happened. On Infinia, every introduction is recorded with the reason it was won.
Payments handled properly
Card payments, stored balances, invoices and payouts on Stripe, so money moves without a spreadsheet.
Tools to run it
An admin desk to approve members, sort out problems and watch activity as it happens.
Room to grow
Start with the core loop and add features as real users show what they need.
What does it cost?
Every project starts with a short discovery call and a written scope: the screens, the rules, the integrations and what’s out of scope. You get one fixed price for that scope before any work begins, working software to review every week, and the code is yours at launch. See how web app projects work.
Usually by starting one side by hand. Many marketplaces recruit a small group of providers personally, then open to customers once there’s something worth finding. A lean first version is built for exactly that stage.
Can the platform take payments and pay out to the other side?
Yes. We build payments on Stripe, which handles card payments, stored balances and, through Stripe Connect, payouts to providers or sellers.
Can we launch with a small first version?
Yes, and we usually recommend it: the core loop of joining, matching and paying first, then features added as real users show what’s missing.
Do you only build marketplaces like Infinia?
No. Infinia matches growing businesses with fractional executives through an auction, but the same building blocks power booking platforms, directories and member portals.
