EVRIKO · Software development
Your on-demand engineering department.
We build the custom software a business runs on, and keep it running after launch. You bring a problem, an idea, or a goal; we handle everything from there to a working system.

What we build
Software wired into how your business runs.
More work than capacity? Agencies, primary contractors, and tech teams with a backlog.
How partnership works →Products
The proof is our own software.
These are our own products, built, shipped, and run by us. We would rather show you working software we operate ourselves than a wall of logos. One of these numbers is a demo you can break; the other is us, live on our own line.

Call the demo line:
+1 (916) 885-0484This is a live AI front desk we built. It answers as Halverson Heating & Air, an HVAC company, not as EVRIKO, so you hear the product the way a real caller would - as if you were one of their customers. It routes emergencies, takes service requests, and quotes a job.
Talk to us
Call our own line:
+1 (562) 534-3320One of our own agents answers it. We build these for a living, so it seemed only fair we run one ourselves. Ask it anything; it takes your details and we follow up in writing.
Recorded and transcribed, so nothing you tell it goes missing.
Hear it
Two real calls on the demo line, start to finish:
Service request - rattling AC
Reads the number back, handles "I don't know the age of the unit," and sets an honest callback expectation.

AgentThanks for calling Halverson Heating and Air. This call may be recorded. This is the front desk - how can I help you today?
CallerHi. My name is Jenny. Um, my AC started making the subwrap window noise yesterday. It's still blowing cold, um, but it's very loud.
AgentHi, Jenny. I'm sorry to hear that - that sounds pretty annoying. Um, before we get into the details, what town are you located in?
CallerI'm in Sacramento. Um, my full address is [address redacted], Sacramento.
AgentGot it, [address redacted] in Sacramento. Thanks for that. And, um, just so I can have the office reach out to you, what's the best callback number for you?
CallerFor, um, it's going to be [number redacted].
AgentOkay, let me just read that back to make sure I have it right - [the number, read back in three groups]. Is that correct?
CallerYes.
AgentGreat, thanks. And just so I can pass along the best info to the team, could you tell me a little more about that noise? Like, is it a grinding sound, or maybe more of a rattling? And do you happen to know the make or about how old the unit is?
CallerUh, it's more of a rattling sound, uh, when it turns on. And, honestly, I have no idea how old it is.
AgentMm-hmm, got it. A rattling sound when it kicks on - that's helpful to know. And don't worry at all about the age or make of the unit; that's totally fine. So, I have you down for a service visit. Someone from the office will call you back to lock in the exact window. Just so you know, there's an $89 diagnostic fee, and we waive that if you go ahead with the repair. Is there anything else I can help you with today?
CallerNo. That will be it. Thank you.
AgentYou're very welcome, Jenny. I hope you have a good rest of your day.
Service visit requested - office to confirm the window.
Callback number and service address redacted. Everything else is verbatim.
Emergency - "just transfer me"
Asks once, then complies. No interrogation, no stalling.

AgentThanks for calling Halverson Heating and Air. This call may be recorded. This is the front desk - how can I help you today?
CallerI need someone out here now.
AgentI'm sorry to hear that. To make sure I get you to the right place, could you tell me what's going on with your system?
CallerJust transfer me.
AgentOf course - connecting you now, stay on the line.
Transferred to the on-call team.
Both calls recorded and transcribed, like every other one. Judge the quality yourself.
Why EVRIKO
Anyone can get an application built now. Ask AI for an app and it will make one. It will even work, right up until production, where there is no issue tracking, no proper logging, no monitoring.
The parts that matter come after launch: software has to stay compliant, hold up underneath, and give you your time back once it runs. That is the part we do - the engineering that turns something that runs into something you can rely on.
You do your business, and we do development.
How working with us goes
Your intent, our implementation.
- 01
You explain what you need
No spec required. You describe what you want, and we keep asking until we have it straight.
- 02
We design the solution
We decide what to build and how it should work underneath, before any code.
- 03
We build it
Production-grade from the start. Monitoring, logging, and error tracking ship with it, not after it.
- 04
We maintain it after launch
It keeps working because someone who knows how it works underneath stays with it.
From point A to point A+.
Who's behind it
Volodymyr (Vlad) Petrusha
Software engineer · 20+ years building software
The person who builds your system is the person who keeps it running, so nothing is lost in a handoff between whoever sold it and whoever maintains it.
How we price
The real cost is inaction: the hours it eats and the work it blocks.
We work in fixed scope, not by the hour, and quote each project up front. Once it is live, a monthly retainer keeps it running and maintained. What we sell is a working system at the end.

Write it however it comes out, or call and talk it through with our own AI assistant. Either way, a person reads it and replies.
