Software and AI/ML Development Services.
Domain Experts for AI Systems
Perimattic is a US-based software engineering company with an office in UK and a delivery centre in India. We design, build, modernize software’s across verticals like AI, SaaS platforms, application modernization, manufacturing systems, and platform engineering.

Independently Verified Client Reviews
Perimattic holds a 4.75 / 5 rating on Clutch based on independently verified client interviews across production engagements since 2018.
“The new architecture is scalable and highly efficient, saving significant fees.”
Perimattic re-platformed our customer engagement systems onto AWS microservices. Their team has been maintaining and evolving the platform since 2018 — production has stayed stable throughout.
“Their professional behavior and around-the-clock stability were impressive.”
Production systems stayed stable 24/7 without us building an in-house ops team. Communication was consistent, and delivery landed on the dates they committed to.

How We Turn Your Use Case Into a Working System
A five-stage process built to eliminate the delays, misaligned expectations, and abandoned pilots that kill most enterprise projects.
Discovery and Scoping
We audit your data, systems, and goals, then define the use case, success metrics, and a go / no-go decision point.
Architecture and Selection
The right architecture for the problem — documented and signed off before building anything.
Development and Iteration
Agile sprints with weekly output and outcome-based billing. You see working builds, not status reports; every sprint closes with a demo.
Integration and Testing
Connected to your CRMs, ERPs, cloud, and APIs — with evaluation for quality, latency, and edge cases.
Deployment and Support
Deployed to your environment with monitoring, maintenance, and retraining built into the engagement.
Use Cases Implemented, Function by Function
The same services, seen from the teams that run them every day.
Invoice exceptions & month-end close
Agents reconcile, investigate exceptions, and draft journals — humans approve the consequential entries.

A full production build — AI system, SaaS platform, or modernized application — with security, monitoring, and integrations.
Post-launch iteration, monitoring, infrastructure management, and feature development on a monthly retainer.
Choosing a Software Development Partner, Answered
What does a software development company like Perimattic do?+
We design, build, and operate custom software: AI systems (ML models, LLM copilots, RAG, agents), multi-tenant SaaS platforms, modernized legacy applications, manufacturing software, and the DevOps infrastructure they run on. One senior team owns the work from scoping through production support.
How much does custom software development cost?+
Published bands: a proof of concept or validation MVP starts around $1,500 (2–10 weeks); a production system — AI, SaaS platform, or modernization — typically runs $4,500–$15,000 (12–20 weeks); ongoing engineering retainers start at $500/month. Every engagement is quoted in writing before work begins.
How long does it take to build custom software?+
A focused proof of concept takes 2–6 weeks, an MVP 6–10 weeks, and a full production system 12–20 weeks. You see a working demo every week from week two — progress is measured in software you can click, not status reports.
Should we build custom software or buy an off-the-shelf tool?+
Buy when a mature product matches your workflow closely; build when the workflow is your competitive advantage, when off-the-shelf tools force costly workarounds, or when you need AI trained on your own data. Most of our clients build after outgrowing at least one purchased tool.
How do I choose a software development company?+
Look for verifiable third-party reviews (not just logos), published pricing, senior engineers doing the work rather than a sales layer, weekly working demos, and contract terms that give you the code, IP, and infrastructure from day one. Ask every candidate the same five questions and compare answers in writing.
Do you work with in-house engineering teams?+
Yes — most engagements are collaborative. We integrate with your repositories, CI/CD, and standups, and hand over documented, tested code your team can own. Knowledge transfer is part of the scope, not an afterthought.
Who owns the code and intellectual property?+
You do. Codebase, IP, cloud accounts, and data remain in your name from the first commit. If the engagement ends, everything you paid for stays with you.
Which regions does Perimattic serve?+
Enterprise and mid-market clients across the United States and United Kingdom, with delivery teams working in overlapping time zones. Our clients operate in more than 12 countries.
