Embedded Engineering and Visibility Work for Funded SaaS Platforms

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 layer is part of what lets an assistant describe the product accurately, alongside documentation, reviews and citations elsewhere on the web, 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.

• Release QA on every change

  Tests are written and run before each release, a merge gate blocks any change while a test fails, and a second reader reviews every change. After release, a browser checks the live product at phone and desktop widths, and you get a signed release report.

• A new SaaS product, built to a written scope

  For a platform that does not exist yet, AppWT runs a fixed-price build with a written scope. Each stage is priced and approved on its own, and you own the code, assets, designs and content.

• Who does the work, and who answers after launch

  A founder-led human team works alongside AppWT's AI systems on every service line. After launch, a named support retainer gives you a specific AppWT engineer with a direct phone number and written response SLAs, and uptime terms are a written agreement.

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.

• A sensor-data platform AppWT builds and runs

  SolarLife24 LLC, a company Tony Paris co-founded, makes instrumented smart PPE. AppWT programs, maintains and runs the server-side platform that reads every sensor in the gear, with reporting layers and a login-protected partner portal for its leadership.

Questions buyers ask about SaaS and Software Platforms

• Who does custom SaaS development for funded software teams?

  AppWT does. A new product is a fixed-price build with a written scope, priced and approved stage by stage. For a funded team, AppWT embeds senior engineers on product and AI features while your DevOps team keeps the infrastructure, and the code belongs to you.

• Does AppWT do web application development?

  Yes. AppWT builds custom web applications, including SaaS products, progressive web apps, databases and the APIs that connect them. A new application is a fixed-price build with a written scope, each stage is priced and approved on its own, and the code belongs to you. AppWT also runs its own live web applications, such as AppWT Analytics at analytics.appwt.com and the document vault at manuals.appwt.com.

• Does AppWT build new SaaS products or join an existing team?

  Both. A new product is a fixed-price build with a written scope, and each stage is priced and approved on its own. For a funded team, AppWT embeds senior engineers who work on product and AI features while your own DevOps team keeps ownership of the infrastructure.

• Who owns the code?

  You do. On a build, the code, assets, designs and content belong to you. Embedded engineers work inside your own cloud account and code host rather than a copy of it, so there is no second architecture, no parallel deployment path and no requirement to hand over the estate.

• How is a release proven before it ships?

  Written acceptance checks are agreed before work starts, and they run twice at the end. On the release QA retainer, a merge gate also blocks any change while a test fails, a second reader reviews every change, and you get a signed report for each release.

• Will AppWT sign our NDA?

  Yes. Platform engagements in this area are usually covered by a mutual non-disclosure agreement, which AppWT signs and honors permanently. That is why most proof on this page is AppWT's own product work, which can be inspected without anyone else needing to grant access.

• Can AppWT promise that AI assistants will recommend our product?

  No. No one controls those answers, so AppWT never promises a ranking or an AI citation. It measures what the engines say and fixes what they read, such as structured data and AI crawler files. That machine-readable layer is measurable before and after, and it works alongside documentation, reviews and citations elsewhere on the web.
