Expert capabilities

Every way we help you ship the right product.

Every build starts with what not to build. Every launch ends with us still in the room. All six services feed into one fixed-price BUILT TO HOLD™ program, and every one of them includes the option to have us run it after.

Not sure which one? Start here.

Internal Systems & Operations Software

The software your business actually runs on. Inventory, orders, bookings, and finance in one system instead of six spreadsheets and a WhatsApp group. Architected so it can become a product you sell to others later, not just a tool you use now.

  • Replaces the SaaS subscriptions you're paying for but barely using
  • Built around your actual workflow, not a generic template
  • Single source of truth, no double-entry, no data living in three places
  • Runs under the RUN retainer after launch

AI Products & Systems

AI workflows and agents built around tasks that happen at real volume and save real hours, or we tell you it's not worth building yet. Every integration ships with audit trails and usage logging built in.

  • Passes a usage test before a line of code gets written
  • Ships with audit trails, EU AI Act disclosure-ready
  • Your data stays yours. No vendor lock-in
  • Runs under the RUN retainer after launch
Explore service

SaaS Applications

Multi-tenant SaaS platforms architected for the users you have today, and built so your first external customer can onboard without touching the codebase. Priced on value, not seats.

  • Multi-tenant from day one, not bolted on later
  • Stripe billing, subscriptions, and payouts built in
  • Built so you could sell access to it, not just use it yourself
  • Runs under the RUN retainer after launch
Explore service

Mobile Apps (iOS + Android)

Production-ready iOS and Android apps built for retention, not just a listing in the App Store.

  • One codebase, both app stores
  • Built for retention, not just the install
  • We handle the App Store / Play Store submission
  • Runs under the RUN retainer after launch
Explore service

Product Websites & Landing Systems

Conversion-first websites built to be found, by search engines and by the AI assistants an increasing share of your customers now use instead of Googling. Not a brochure. A revenue layer.

  • Built to convert, not just to exist
  • Structured data and AI-search visibility baked in from day one
  • Fast by default: no bloated page-builder stack
  • CMS access so you never need a developer to change a word
Explore service

WB-12 Audit & Recovery

You built something fast and now you need to know what you're actually holding. The WB-12 audit tells you in 5 days, what's solid, what's fragile, and what it would honestly cost to fix. Recovery scoped after, not before.

  • WB-12 audit first, 12 checks, written report, straight verdict
  • Most products need finishing, not rebuilding, we'll tell you which
  • Migrate users and data with zero downtime if a rebuild is needed
  • Moves into RUN retainer after recovery, so it never slips again
Explore service

RUN: Ongoing Operations

Your software, operated by us. The part that decides whether everything else mattered, and the part almost nobody else offers.

  • Monitoring, alerting and incident response, we find out before you do
  • Security patching and dependency upgrades on a fixed schedule
  • Compliance evidence kept current, ready for any diligence request
  • Small changes and fixes included each month
  • Monthly CTO review, what's coming before it arrives

First 90 days included after any BUILT TO HOLD™ build.

Why choose us

Why founders choose Witsberry.

01

CTO-led judgment

We decide what not to build before a single sprint starts, so budget goes toward what drives traction, not scope creep.

02

Senior-only execution

No junior hand-offs, no learning on your dime. One senior team, architected for your product from day one.

03

Five guarantees, in writing

Verdict, ship-date, scope-lock, never-hostage, built-to-hold. Miss the date and every week late is free.

04

Fixed price, no surprises

One number, paid across milestones tied to working software. No scope creep, no surprise invoices.

05

100% IP ownership

Every line of code, every design file, every credential. Yours from day one, not on some future handover date.

06

Still running, years later

Not launch screenshots, live products. The same builds, still in production, with the same team still behind them.
