The systems we run on ourselves first
Most of what follows is not a client list. It is the set of travel brands inside the Under2 ecosystem that our software has to keep working every day, which is a harder test than a case study.
Read this first
Every brand named on this page belongs to the Under2 ecosystem. They are not third-party clients and nothing here is a customer reference. We say it at the top rather than in a footnote, because a portfolio that quietly presents in-house brands as clients is the most common dishonesty in this industry.
A second thing we do not do here: publish results. There are no traffic figures, no revenue, no conversion rates attached to any project below. A number without an independently verifiable source is decoration, and travel technology is full of it. What this page shows is which kinds of system we have had to keep alive, and what each of them forced into the products.
Alotour — inbound DMC, running on Bokun
Alotour is an inbound DMC selling Vietnam to foreign visitors, and it runs on Bokun. That single fact is why our team knows Bokun the way it does — not from documentation, but from a business that loses money when a product mapping is wrong.
An inbound DMC is a demanding case for software. Products sell in several currencies to buyers in several time zones, agents ask for holds before they confirm, and the same tour exists as a private departure, a joined group and an agent rate at once. Every one of those is a way for availability and price to disagree.
The integration work we sell is shaped around failures we hit ourselves: stale prices pushed by a channel, catalogues that match on name and nothing else, holds that expire at the worst possible minute.
La Pinta Travel and Hanoi Free Walking Tours
La Pinta Travel is another operating brand in the ecosystem. Hanoi Free Walking Tours sits at the opposite end of the spectrum from a DMC: the guest journey is short, the booking window is measured in hours, and most traffic arrives on a phone from a hotel lobby.
Short-lead-time products punish slow websites in a way long-haul tours do not. Somebody deciding what to do this afternoon does not wait four seconds for a page. That is where our habit of building static, self-contained sites with no third-party scripts came from — not from a benchmark score, from watching how people actually book a tour that starts in two hours.
Vietbuddies — the one with no payment at all
Vietbuddies runs free tours. No money, no checkout, no payment gateway, and there never will be. It is the clearest example of something we say on the payment page: a booking system is not a payment system, and plenty of travel businesses need the first without the second.
Remove payment from a booking flow and what remains is more interesting than it sounds. Capacity is still finite, because a guide can only walk with so many people. Confirmations still have to arrive and be understood abroad. Cancellation matters more, not less, because nothing was paid — a free booking is the easiest thing in the world not to turn up to, so the reminder and the release rule carry the whole operation.
- The system has to lose the payment step entirely, not hide it behind a zero price. A checkout charging nothing is a checkout that will still fail.
- No-show behaviour is the real problem to design for, not fraud.
- The confirmation and the reminder do the job the deposit does elsewhere.
- Any platform assuming money exists in every flow fails this case, and a surprising number of them assume exactly that.
Destination and DMC sites
Alongside the operating brands sits a group of destination and DMC-facing sites. They share one engine and one publishing approach, and they are where the website service was actually developed.
| Site | What it covers |
|---|---|
| mekongvoyagers.com | Mekong region travel |
| vietnamvoyagers.com | Vietnam programmes |
| indochinasignature.com | Multi-country Indochina itineraries |
| holidayindochina.com | Indochina holidays |
| micephuquoc.com | MICE in Phu Quoc |
| micedanang.com | MICE in Da Nang |
| danang.co | Da Nang destination |
| halong.co | Ha Long destination |
Building the same kind of site repeatedly turns a website project into a system. Structured data, itinerary pages, enquiry handling and how a booking path behaves on a phone stopped being per-project decisions and became defaults, which is why a new site takes weeks rather than months.
MICE sites deserve a note. Nobody buys a conference for two hundred people from a checkout. Those sites exist to produce a qualified enquiry, and their design goal is the quality of the form submission, not a booking count.
Why a technology company holds more than 239 domains
Under2 manages a portfolio of over 239 domain names. The honest answer to why has four parts and no mystique.
- Regional travel demand is destination-led. People search for a place before a company, and a clean destination name is a durable asset in a way a company name is not.
- Live brands need their neighbours held. Misspellings and variants of a brand you operate are cheap to hold and expensive to buy back from whoever noticed first.
- Products and phases need names in advance. TourAuct runs on two — tourauction.com for suppliers, daugiadulich.com for Vietnamese consumers — and that split was decided long before either launched.
- Most are not live sites and are not presented as such. A portfolio is an inventory, not a claim about how many websites we operate.
Renaming a live travel brand is genuinely expensive — every OTA listing, every gateway record, every printed voucher, every inbound link. Holding the right name early is one of the few things in this business that is cheap now and dear later.
What running our own products taught the software
Being an operator and a software company at once has one specific advantage, and it is not credibility. We cannot ship a plausible-looking system and move on, because we are the ones who answer the guest.
| What we learned by running it | Where it ended up in the product |
|---|---|
| Availability in two systems eventually sells the same seat twice | One source of truth, and the acceptance gate before any migration |
| A guest who does not recognise the statement name disputes the charge | Brand, entity and descriptor treated as one decision, not three |
| A free product still needs capacity, confirmation and release rules | Payment is a removable module, not a required step |
| Short-lead-time bookings are lost to page weight | Static sites with no third-party scripts in the booking path |
| An enquiry that is lost is worse than one that is slow | Enquiries are written to a log file before any external call is attempted |
The last row is the smallest and the one we would keep if we could keep only one. Every form on this site writes to disk first, then sends to Lark and to email. When a webhook is down, the enquiry is still there. That is not clever engineering; it is what you build after losing one.
What this page cannot tell you
An in-house portfolio proves some things and not others.
- It shows the systems survive daily operation. It does not show how we behave with a third-party client — ask for references in the conversation instead.
- It shows breadth of travel product, from a free walking tour to a MICE enquiry. It does not show scale beyond what we publish: over a thousand merchant sites on izBooking, and nothing else quantified.
- It is not relevant to you at all if you are outside travel. We do not take that work.
- It does not include results, and it will not start to. Any figure here would be one we produced and audited ourselves, which is not evidence.

Tell us what you sell and how bookings reach you today. We will point at the build above that resembles it and what it cost in time.
What travel operators ask us most
Are these your clients?
No. Every brand named on this page is part of the Under2 ecosystem, built and operated in house. We say so at the top of the page for that reason.
We do have external clients, including merchants on izBooking. Their names are theirs to publish, not ours.
Why are there no results or traffic numbers?
Because we would be the source, the auditor and the beneficiary of every figure, and a number like that is worth nothing to a reader who cannot check it.
In a conversation we will talk about what a specific build cost in weeks and what changed operationally, which is checkable against your own situation.
Can we see a demo of one of these systems?
The public sites are live and you can use them. For the booking side, we will walk through a real flow with you rather than a prepared demo environment, because the interesting parts are cancellations, holds and refunds.
For izBooking specifically the product page describes what the platform does and what stage the 2026 rebuild is at.
Do you build sites for operators who compete with your own brands?
Yes, and it is worth understanding how that is kept clean. We do not sell tours in competition with operators running on our platform, and product data belongs to the merchant.
If a specific overlap concerns you, raise it before the scope is signed and we will put the boundary in writing.
