The business apps your team needs,
built and integrated for you.

Trusted by over 250+ high-performing companies

WHAT WE DO

What OpenXcell actually does.

You tell us the business app you need. A forward-deployed engineer — a senior builder who embeds with your team — uses AI and the best no-code tools to build it on top of your existing software, and ships it in weeks.

A senior human engineer

Not an AI agent. Not an offshore ticket-taker. A senior builder who sits with your team, learns your workflows, and is accountable for the result.

WHY NOW

Why custom software finally makes sense for mid-market

For years, custom software meant a 4-person team for 6 months and a $300K bill. So mid-market companies just lived with the friction. Three things changed that.

01

Vibe coding

AI-augmented engineers ship in weeks what used to take quarters. Custom software finally fits a mid-market budget.

02

Headless SaaS

Every major SaaS now exposes its data through APIs. We build the interface your team actually needs on top.

03

Forward-deployed engineers

No specs and handoffs. Our engineers embed with your team and ship working software from week one.

"Every B2B software company is (or should be) building a 'headless' version of their product. But 'headless' doesn't mean 'brainless.'"

HOW IT WORKS

No prompting,
No debugging. Just results.

Everything is handled by our forward-deployed engineers, augmented by AI. You bring the problem — we bring the working software.

Discover & Assess

We embed with your team, map the SaaS tools you already use, and find where the friction is. You end week one with a clear build plan and a fixed-price quote.

Week 1-3

Your FDE builds the app — picking the right tool for the job — and wires it into your existing stack and proprietary data. You see working software in week one, refined every day after.

Deploy & Own

We ship to production, hand over full ownership, and document everything. The app lives in your accounts. Extend it with us on retainer, or run it yourself.

WHAT WE COMMIT TO

Three commitments, No fine print.

Every engagement, every customer, every time.

user

01

Working software in weeks.

Not a spec. Not a wireframe. Actual functional software you can click, by the end of week one. If we can't ship that, we shouldn't be running the project.

02

Fixed-FDE T&M pricing, No scope-creep.

After a 30-minute scoping call, you get a clear, fixed engagement price within 48 hours. No surprise change-request invoices, no billable-hour creep mid-project

03

Full code ownership, No lock-in.

All code and apps live in your accounts, your repos, your infrastructure. When the engagement ends, your team can extend, maintain, or migrate without us.

FAQ

Common Questions.

The things mid-market buyers ask before booking a call.

Do we own the code at the end?

Yes — fully. All code is delivered in your repos, on your infrastructure, in your accounts. When the engagement ends, your team can extend, maintain, or migrate it without us. No vendor lock-in.

What if our SaaS vendor changes its API?

How is this different from a contractor or traditional dev shop?

What's the smallest engagement you take?

Do you replace our SaaS, or just sit on top?
