Automation for mainframes, terminal apps, and legacy software.

Overview

What we deliver

We automate processes that depend on mainframes, green-screen terminals, and unsupported legacy applications without forcing premature system replacement.

We help organizations automate work on legacy platforms that cannot easily be replaced or modernized in the short term. Our team builds reliable automations against mainframes, AS/400, terminal emulators, Citrix-published applications, and desktop software with no usable APIs. We use a mix of RPA, screen scraping, terminal protocols, and image-based automation where required, always layered with strong exception handling. We document interface behavior and version every automation so changes in legacy screens do not silently break production. We also help you sequence work so automation becomes a bridge to modernization rather than a permanent workaround. Where APIs or middleware can replace screen-based steps, we propose those improvements. Where they cannot, we deliver automations that are stable, auditable, and easy to support. Our work helps you reduce manual effort and free capacity while modernization plans mature.

Client stories

What clients say

"

Two weeks before our seed round we still did not have a defensible model. Their fractional CFO rebuilt our three-statement forecast, pressure-tested the assumptions, and walked me through every line before the partner meeting. We closed 1.4M on the terms we wanted. The investor specifically called out how clean the financials looked compared to the last five decks she had seen.

We had 14 cornerstone pages stuck on page two for 18 months. Their SEO crew rewrote the internal linking, cleaned up our schema, and shipped 22 supporting briefs over a quarter. Eight of those pages broke top three by month five. Organic pipeline went from a trickle to our second-largest source. Felt like watching interest compound.

FAQ

Frequently asked questions

Quick answers to the questions we hear most.

Can you automate mainframe processes?
Yes, we automate against 3270 and 5250 terminals, with options for HLLAPI where available.
What if the legacy system has no API at all?
We use stable terminal protocols or UI automation with image and OCR techniques as a fallback.
How do you keep automations stable on old systems?
We isolate interface details, version automation code, and add resilience for screen variations.
Will automation block our modernization plans?
No, we design automations as bridges and flag where APIs or replacement systems would be better.
Can you automate Citrix-published applications?
Yes, we use platform features and computer vision techniques designed for Citrix environments.

Stuck with manual work on legacy systems?

We automate mainframe and legacy processes while modernization plans mature.
