Our story

From custom software to custom AI agents.

VantaSoft started in Irvine in 2021 as a software development company. For years, our work was building and maintaining production software for growing companies like Amira Learning, Butterfli and serviceMob. Along the way we led six fractional CTO engagements for companies that needed technical leadership without a full-time hire.

We also built a product of our own. Telvana’s AI agents answer calls, texts and website chats for contact centers and BPOs.

As AI agents got good enough to do real work, we started running VantaSoft on them. In 2026 we made building custom AI agents for other businesses our main service. We still offer CTO advisory and custom software.

We use what we build

VantaSoft runs on its own agents.

These agents work with our team in Slack every day, on the same kind of setup we build for customers. Running them ourselves is how we learn what holds up in day-to-day work.

What we do

Three ways to work with us.

01 VantaSoft Agent Service

Custom AI agents

Each agent is built around one job on your team and the tools you already use, and it works in your existing messaging platform, like Slack or Microsoft Teams. We build it, then host and maintain it.

02 CTO Advisory

Fractional CTO advisory

You get a CTO on your leadership team without the full-time hire. We set technical strategy, plan your roadmap and team, and evaluate vendors with your leadership.

03 Custom Software

Senior-level custom software development

Our senior engineers design, build and maintain production software for companies like Amira Learning, Butterfli and serviceMob.

How we work

What you can count on.

  1. 01

    Senior people on your work

    Your work is led by senior engineers, and our founders stay involved.

  2. 02

    Built around your business

    Every agent and project starts from how your business works and the tools you already use.

  3. 03

    Straight advice

    If something you ask for will cost you later, or isn’t the right fit, we’ll say so and tell you what we’d do instead.

  4. 04

    We stay after launch

    We host and maintain the agents we build and coach your team as they start using them. On software, we stay on for maintenance and new features, or hand the code to your team when you’re ready.

“They don’t just build something and disappear, they stay involved, support you whenever you need it, and treat your business like it’s their own.”
