Embedded Engineering and Visibility Work for Funded SaaS Platforms
A funded platform approaching beta has a different problem to a company that needs a website. It needs someone who has shipped billing, deliverability and a product surface that AI assistants can actually read, and who will work inside an existing engineering process rather than around it.
Who this page is written for
Funded software companies with a product near completion and a launch date, whose own DevOps team owns the infrastructure and who need senior product and AI engineering on top of it, plus the commercial surface that gets the product found.
What AppWT delivers for SaaS and Software Platforms
-
Embedded senior development on top of your infrastructure
AppWT works on product and AI features while the in-house team keeps ownership of infrastructure. No second architecture, no parallel deployment path, and no requirement to hand over the estate.
-
Billing that fulfills exactly what was paid, exactly once
Fulfillment is refused unless the payment cleared, is keyed to the payment intent rather than the checkout session, and is made idempotent by a database primary key. The slow part of a webhook is queued so the provider does not time out and retry, because retries are how duplicate fulfillment is born.
-
Deliverability treated as an engineering problem
SPF, DKIM and DMARC alignment, one sanctioned outbound path, and no click tracking on anything that matters. A transactional email that lands in spam is a product defect, not a marketing issue.
-
The machine readable surface most platforms are missing
Many funded products ship with no sitemap, no llms.txt, no ai.txt, no canonical tag and no structured data anywhere on the marketing site. That is the layer that decides whether an assistant can describe the product accurately, and it is measurable before and after.
-
Accessibility built into the product surface
Conformance work applied to the product itself, not only to the marketing pages, because enterprise procurement asks about the thing users log into.

The proof that exists
-
AppWT ships and bills its own software products
A document vault at manuals.appwt.com, an analytics platform at analytics.appwt.com, an AI chat product at aichatbot.appwt.com, transcription at transcribe.appwt.com, a QR platform at qr.appwt.com and a credits product at credits.appwt.com are all live and all billed. These are running products with paying subscribers rather than demonstrations.
-
A privacy first analytics platform built in house
AppWT Analytics requires no cookies, is built for GDPR and CCPA compliance, filters AI bot traffic and is not a wrapper around a third party product. The numbers published on the AppWT case studies page are pulled from it live.
-
Billing correctness learned the hard way and fixed
AppWT found and fixed a defect in its own payment webhook where payment status was never checked and two separate provider events both triggered fulfillment. The rules that came out of that incident are now enforced in code and applied to client work.
Straight answer. Platform engagements in this vertical are typically covered by a mutual non-disclosure agreement, which AppWT signs and honors permanently. That is why the proof shown here is AppWT's own product work, which can be inspected without anyone else needing to grant access.
