Software and marketing for businesses ready to work differently.

Whether you know exactly what you need or just know something has to change, we'll work out what to build, build it, and connect it to the way you win customers.

What we've built

We don't just talk about where software is going. We build it.

🔥 HotLead is our own software for winning and following up leads, for any business that sells to customers. It's live, businesses are paying for it, and AI assistants can operate it.

  • LiveIn use by real businesses today.
  • AI-readyAI assistants can operate it safely.
  • Built to learnEach page improves from its own results.

One of our customers connected their own AI assistant to HotLead. It built 11 funnels and 53 posts on its own, using the same screens a person would. That's where business software is heading, and it's how we build for our clients.

How we build

Software that fits the way your business already works.

It works where your people already work.

A technician with dirty hands won't fill in a form on a phone. So we build around WhatsApp, voice notes and photos, not another dashboard to log into.

Your AI assistant can use it.

Everything we build can be operated by AI assistants like ChatGPT and Claude, safely, so it stays useful as the way you work changes.

The rules live in the software.

Things that must never happen, like publishing a page with made-up facts, are blocked by the system itself. A guideline in a document can be ignored. Software can't.

You pay for results, not seats.

We price around what the work achieves, not how many logins you have.

Who you'll work with
Darryn Mountfort, founder of Keene Growth

Who you'll work with

Hi, I'm Darryn.

I've spent 25 years building software, 16 of them as a hands-on CTO. Keene Growth is where that meets the marketing side: making sure the right people find your business, understand it, and take the next step.

You work with me directly. I'll ask questions, challenge assumptions when it helps, and build the thing myself.

Your turn

Your turn

Where are you starting from?

Every business we talk to is at a different point. Which one sounds like you?

“Something has to change. I'm just not sure what.”

Maybe it's the spreadsheets, the paper job cards, the enquiries that slip through, or the hours spent on admin nobody enjoys. You know there's a better way, but not where to start.

The 3-week fix. In week one we sit with how your business actually runs and find where it loses the most time or money. In weeks two and three we build one working thing that fixes it.

YOU GET
One problem found and fixed, plus a clear list of what to tackle next.
PRICE
Fixed price, agreed before we start.

“I know what I want. I can't find the right person to build it.”

You've got the idea, the process or the half-finished system. What you need is someone who can understand the business and build it properly.

Custom software and integrations. Web apps, internal tools, AI assistants, and connecting the systems you already pay for. Scoped and quoted up front. For larger businesses, Darryn can also step in as a part-time CTO.

YOU GET
Software built for your business, which you own.
PRICE
Quoted per project.
