We help mid-market leaders convert AI ambition into measurable enterprise value — what we call your AI value dividend that shows up in your numbers, not just your slide decks.
Three things happen when Omnisenti works with your leadership team:
We audit your AI readiness across strategy, people, technology, and execution — surfacing uncomfortable truths so your investments go to the right places first.
We build a sequenced roadmap with quantified business cases for every initiative. Your board gets numbers, not narratives. Your team gets clarity, not overwhelm.
We don't hand over a report and disappear. We embed in your execution rhythm — fractional Chief AI Officer, delivery teams, Command Room dashboards — until the value shows up in your numbers.
300–2,000 employees. Revenue $50M–$500M. AI is on the agenda but not in the operations.
Portfolio companies sitting on unrealised value. AI as a valuation multiplier across holdings.
Long-horizon businesses where key-person risk must shift to systems-based value.
Founder & Principal
Executive advisor. Certified AI Coach. Sydney-based.
I help C-suite leaders in the Sydney market turn AI from a boardroom talking point into a measurable driver of enterprise value. My clients are mid-market firms (300–2,000 employees) and Private Equity portfolios who need more than a slide deck — they need a partner who embeds in their execution and stays until the numbers prove it worked.
As a Certified AI Coach through AICoaches.com, I bring the battle-tested frameworks from Untangling AI (Wiley, 2026) — the strategic playbook for enterprise AI adoption — and apply them through the Agentic Equity Model, a proprietary methodology I developed for the Australian mid-market.
The result? Not another AI initiative that fizzles after the launch meeting. A disciplined, measured programme that creates tangible ROI — the measurable value of autonomous AI workflows that compounds into permanent value.

Your guided path from AI curiosity to daily operating advantage. Works with whatever AI tools you have today — and builds toward something more powerful.
AI is a conversation, not a command line. Open whatever AI tool you have — ChatGPT, Gemini, Copilot, Claude — and paste this in. No special syntax. No magic words. Just talk to it like a smart colleague.
I'm going to paste an email I received. Can you: 1. Summarise the key points in 2-3 bullet points 2. Flag anything that needs my attention or decision 3. Draft a brief, professional reply Here's the email: [paste your email here]
The AI breaks the email into clear points, highlights what matters, and drafts a reply you can edit and send. If anything is unclear, a good AI will ask rather than guess. This works in ChatGPT, Gemini, Copilot, or Claude — try it in whichever you have open.
Try pasting something real — a vendor email, a board paper summary request, even a meeting invite you need to decline gracefully. Real tasks teach faster than toy examples.
Most people use AI like a search engine. The real power comes from giving it context first, then asking for what you need. This prompt structure works for almost any business task.
Context: [Describe your situation in 2-3 sentences] Task: [What you want the AI to do] Constraints: [Any limitations or requirements] Output format: [How you want the response structured] Example: Context: I'm preparing for a board meeting next week. Our Q3 numbers are strong but we had some customer churn in the enterprise segment. Task: Help me draft talking points for the board Constraints: Keep it to one page, focus on forward-looking actions Output format: Bullet points with recommended narrative flow
Most executives already have access to multiple AI tools through their organisation — they just don't know it. Here's how to audit what you have.
Check these in order: 1. Microsoft 365 → Look for "Copilot" in your apps 2. Google Workspace → Check for "Gemini" features 3. Your company intranet → Search for "AI" or "ChatGPT" 4. Ask your IT team: "What AI tools are we licensed for?" 5. Check your phone: iPhone has Apple Intelligence; Android has Gemini Don't buy anything new until you know what you already have.
Not all AI models are the same. Understanding the trade-offs helps you choose the right tool for the job.
Fast & Cheap (Good for drafts, brainstorming): - ChatGPT 4o-mini - Claude Haiku - Gemini Flash Balanced (Most business tasks): - ChatGPT 4o - Claude Sonnet - Gemini Pro Deep Thinking (Complex analysis, strategy): - ChatGPT o1 - Claude Opus - Gemini Ultra Rule of thumb: Start with the balanced tier. Upgrade if the task is complex or high-stakes. Downgrade if you're just exploring ideas.
Most executives think faster than they type. Voice memos are the fastest way to get your thoughts into AI. Record a rambling voice note, transcribe it, then let AI extract the signal from the noise.
Step 1: Open your phone's voice recorder (or Voice Memos on iPhone). Step 2: Record yourself answering this question for 60 seconds: "What's the one thing on my plate right now that I keep avoiding? Why am I avoiding it? What would 'done' look like?" Step 3: Use your phone's built-in transcription, or paste the audio into ChatGPT/Gemini. Step 4: Paste the transcript into any AI with the prompt below. That's it. Five minutes, start to finish.
I just recorded a quick voice memo about something I've been avoiding at work. Clean up the transcription and give me: 1. The core issue in one sentence 2. Why I'm probably avoiding it (based on what I said) 3. The smallest possible next step I could take in the next 30 minutes Don't overthink it. Keep it short. [paste transcription here]
Four prompts for the highest-value executive use cases. Each works best with a real situation — not a hypothetical. Pick one that matches something on your plate today.
I'm going to describe a plan I'm considering. Before you help me improve it, I need you to be genuinely critical. The plan: [describe your plan] Stakeholders: [who's involved or affected] Stakes: [what happens if this goes wrong] Constraints: [budget, timeline, political realities] Give me: 1. The three most likely ways this plan fails 2. The assumption I'm making that I probably haven't tested 3. The question someone will ask in the meeting that I don't have a good answer for yet 4. One specific change that would meaningfully reduce the biggest risk
Before I ask you to produce anything, here's my situation — use every detail to shape your response. My role: [your title and what you actually do] Audience: [who will see the output] Stakes: [why this matters] Constraints: [what I can't change] Political landscape: [who supports this, who doesn't, who's undecided] Now, with all that context: [your actual request]
I'm going to paste something I've written. Don't fix grammar or polish sentences — tell me what's structurally wrong. Specifically: 1. What's my weakest argument? 2. What insight is buried that should be leading? 3. Where does my logic contradict itself? 4. What am I not saying that the reader will notice is missing? Preserve my voice. I want structural feedback, not a rewrite. [paste your draft here]
Most people use AI to polish grammar. That's the least valuable thing it can do. The real leverage is structural feedback — does this argument hold together? Is the most important point leading or buried on page 3? AI can read your 20-page report in seconds and tell you where the logic breaks. This is the difference between using AI as a spell-checker and using it as a thinking partner.
I'm going to describe a complex decision. Think through it carefully before answering — show me the tradeoffs you're weighing. The decision: [describe it] Options I see: [list them] What makes this hard: [the tension or tradeoff] Timeline: [when I need to decide] Walk me through your reasoning step by step. Flag your assumptions explicitly. Tell me what information would change your recommendation. I want to see the thinking, not just the answer.
Stop using AI just for conversation. Use it to produce real outputs — documents, presentations, spreadsheets, and simple tools. Here's how, using the software you already have.
I need to create a one-page executive brief for my leadership team on [topic]. Structure it as: 1. Situation (2-3 sentences — what's happening) 2. Implications (3 bullet points — why it matters to us) 3. Recommendation (1 clear action with timeline) 4. Next Steps (who does what by when) Keep it to one page. Use clear, direct language. No jargon. This needs to be something I can paste into [Word / Google Docs] and send in 5 minutes.
You'll get clean, structured text ready to paste into your document tool of choice. The AI does the thinking and structuring — you handle the formatting. Tick your software suite in Stage 3 to get tailored instructions.
Need a chart, diagram, or custom graphic? Use ChatGPT or Gemini to generate it ("Create a simple flowchart showing our 3-step approval process, professional style, blue and white"). Download the image and insert it into your document or slides. AI-generated images + AI-written content = professional output without a design team.
You don't need to be a developer to build internal tools. Replit Agent lets you describe what you want in plain English and iterates until it works. Think of it as telling a builder what you want — you describe the kitchen, they build it, you say "actually, move the sink" and they adjust.
Build me a simple web-based calculator for our team to estimate AI automation ROI. Inputs: - Number of employees affected - Average salary (AUD) - Estimated productivity gain (percentage slider, 5-30%) - Current EBITDA multiple Outputs: - Annual savings - Enterprise value uplift (savings x EBITDA multiple) - Cost per employee saved Make it clean, professional, mobile-friendly. Dark theme. No login needed.
A working web app in minutes. You can share the link with your team. Need to add a field? Just describe it. Want to change the colours? Ask. The iteration loop is fast and conversational.
Internal calculators, simple dashboards, data entry forms, presentation tools, team voting apps, project trackers. Anything where you'd normally ask IT for a spreadsheet or wait 6 weeks for a dev team. Start small — one tool that solves one annoyance.
To use Cowork, you need Claude Desktop with a Pro subscription. Here's the setup path.
1. Go to claude.ai/download and install Claude Desktop 2. Sign in with your email 3. Subscribe to Claude Pro (USD $20/month) — this is required for Cowork 4. Open Claude Desktop — you'll see the chat interface 5. In the next stage, we'll enable Cowork and connect your apps Why Pro? The free tier is limited in messages and doesn't include Cowork. Pro gives you higher usage limits, access to all model tiers (Haiku, Sonnet, Opus), and Cowork mode which connects to your files and apps. For business use, Pro also means your conversations are not used for training.
Cowork connects Claude to the tools you actually use. Once connected, it can read your calendar, search your email, access your files, and create real documents — all from conversation.
In Claude Desktop, go to Settings and enable Cowork mode. Then connect: ☐ Google Drive — so Claude can read and create files in your Drive ☐ Gmail — so Claude can search your email and draft responses ☐ Google Calendar — so Claude can see your schedule and prep for meetings ☐ Select a working folder on your computer — where Claude saves files you create together Each connection asks for your permission. You control what Claude can access.
I want you to interview me to build a profile for my Custom Instructions — the persistent context that shapes every conversation we have. Ask me about: 1. My role, company, and what I actually spend my time on 2. My communication style and preferences 3. The software and tools I use daily 4. The types of tasks I'll most often bring to you 5. Things that annoy me in AI responses (formatting, tone, assumptions) Ask one question at a time. After the interview, generate a clean profile I can paste into my Custom Instructions.
Don't do anything yet. Explain what you think I'm asking for and wait for me to confirm. Look at my calendar for this week and: 1. Identify any meetings that don't have agendas or prep notes 2. For each one, draft a brief prep note based on what you can find (participants, previous meetings, relevant emails) 3. Flag any scheduling conflicts or back-to-back meetings with no buffer 4. Suggest one meeting I could probably decline or shorten
Cowork reads your actual calendar, cross-references with your email, and produces prep notes for real meetings. Files appear in your selected folder. Links are clickable. This is AI as infrastructure — connected, contextual, and working with your real data.
