A small, senior team building custom marketplaces, dashboards, and platforms — for businesses that have outgrown spreadsheets, WhatsApp, and off-the-shelf tools.
Most businesses don't need another SaaS subscription. They need the one system that fits how they actually work.
Orders, stock, and customers live in a dozen chats and sheets. Nothing reconciles, nobody trusts the numbers.
You're bending your business to the software instead of the other way around, and paying per seat for features you'll never use.
You've got a product or a marketplace in mind, quotes from agencies that take months, and no way to test it fast.
The systems your business runs on — designed to scale, built to last, shipped to production.
Multi-sided products — listings, carts, seat maps, checkout that converts.
High-reliability rails, disbursement, and gateways — the same rigor behind a payments unicorn.
Operations that run themselves — orders, stock, and real-time numbers investors trust.
Installable, offline-ready, fast — native feel without the app-store tax.
ISO 27001-grade security and audits that clear procurement for banking and enterprise clients.
Kubernetes, cost control, and 99.99% uptime — architecture that holds under real load.
Greenfield rewrites of aging systems to a modern stack — without stopping the business.
LLM and image pipelines wired into what you run — assistants, extraction, content at scale.
Website-in-a-day to a custom build — premium from the first pixel.
A premium concert-ticketing marketplace — event listings, seat categories, and a checkout that converts, backed by an admin dashboard that runs the whole operation. Mobile-first PWA, payments, and automated e-tickets over WhatsApp.
See the live proposal →The team has designed and engineered products used across Indonesia and Southeast Asia — from a payments unicorn to edtech, POS, and performance software. Real products, real users, real problems.

Goals, work, and reviews scattered across tools that never drive real outcomes.

Accepting and moving money across dozens of fragmented payment rails in SEA.

Students memorizing to pass exams instead of learning how to think.

Small businesses chasing payments with manual invoices and spreadsheets.
Small merchants running sales on paper and cash drawers, with no data to grow on.

Booking vetted event staff — ushers, models, promoters — without the informal chaos.

Running a 120-pair, 16-court national tournament by hand — scheduling, scoring, brackets.
We map the real problem, the users, and what "done" actually means.
Flows and interface first — you see it before we build it.
Production code in weekly increments. No black boxes.
Live, on your domain, tested — the Launchpad moment.
Six months of care, or a retainer for the long haul.
Thirteen is a tight, senior team out of Jakarta — small enough that you work directly with the people building your product, experienced enough that we've done it at the scale most agencies only talk about.
Tell us the problem. We'll tell you honestly whether we're the team to solve it.
