Custom software and AI agents
San Diego, CA · Since 2001 · lithyem.net

Enterprise-grade software for every business.
Agent-ready by default.

Custom software and AI agents for founder-led companies. Production grade, wired into your real workflows, owned by you at delivery.

Who this is for

CEOs and founders of $5M to $50M companies stuck with manual processes, disconnected systems, or a legacy tool the whole business depends on. No in-house dev team, no AI expertise, no patience for hype.

Your team runs on spreadsheets, email threads, and a 15-year-old desktop app nobody wants to touch. Every rule lives in someone’s head. You know AI matters. What you haven’t found is someone who will build a real system, wire AI into it where it counts, and hand you the keys.

What we build

Custom business software

Web platforms, client portals, workflow systems, and mobile apps built to production grade. Structured data, enforced rules, audit trails. Not a no-code prototype that breaks in month three.

AI agents and AI features

Document OCR and validation, survey scoring, lead re-engagement, and autonomous agents that run a workflow end to end. We use AI where it does real work. If it’s decoration, we cut it.

Legacy replacement and integration

Legacy desktop apps, paper processes, and patchwork toolchains consolidated into one purpose-built platform, connected to your CRM, ERP, and accounting.

Every system we ship is agent-ready. The structure that serves your team today (structured data, deterministic rules, audit trails, API and MCP access) is what lets an AI agent run it tomorrow. No retrofit.

How we work

  • Phase-gated commitment. Stop after Discovery, Design, or Development and keep everything we produced.
  • Live deliverables, not PDFs. Specs and clickable prototypes you can use before production code is written.
  • Weekly billing, weekly review. Defined increments, a report every week, no surprises.
  • You own the IP. Always. All code and docs transfer at delivery. No license, no lock-in.
  • Post-launch tuning. Configuration and prompt tuning once the system is live.

Why Lithyem

25 years of building software, not 25 months

AI is a new tool in a process we’ve run since 2001. Discovery, spec, build, ship.

One senior builder, end to end

Discovery through deployment with the same person. No handoffs.

We speak business

Outcomes, hours saved, errors removed. You will never need to translate.

Surgical AI

No ChatGPT wrappers. AI goes at the exact point in a workflow where it removes a decision or a repetitive task, and we measure it.

Referral guide. Who to send our way.

Lithyem · for partners

Think of Lithyem when you hear a CEO say

“We’re still running the business on spreadsheets, a desktop app from 2009, or paper.”
“Our people spend half their week re-keying data between systems.”
“Every client has to send us the same ten documents and someone has to chase them.”
“We have rules for this, but they only work when the right person remembers them.”
“I know we should be using AI. I have no idea where to start.”
“We tried a no-code build. It fell over.”
“I need my clients to be able to log in and do this themselves.”
“I want to grow without adding headcount.”
Best fit: founder-led, $5M to $50M revenue, one clearly painful workflow, and a decision maker who can say yes.

Who not to send

  • Companies that want a marketing website, branding, or copywriting
  • Companies that want an AI strategy deck with no intention to build
  • Anyone shopping for the cheapest hourly rate
  • Projects with no identifiable workflow target or measurable outcome

What we don’t do

Marketing websites and copywriting. Custom branding beyond basic theming. AI strategy without implementation. Hourly retainers without defined scope. Projects with no measurable outcome.

Three ways to start

Free

AI Jumpstart

A 30-minute call and a custom-built AI tool that solves one real problem. You keep the tool.

30 days, fixed fee

AI Strike

One expensive bottleneck. One to three custom AI tools or agents built to remove it. Fixed scope, flat fee.

1 to 2 weeks

Discovery

We verify the problem, assess feasibility, recommend the architecture, and scope the build. No code written, no obligation to continue.

Larger builds follow the Discovery → Design → Development path. Standalone deliverables at every phase. Full IP transfer at delivery.

How to make the intro

Email intro with one line on the company and one line on the pain. Michael replies within one business day and books the first call directly. Referral partners are credited on every engagement they source.
