Solo Consultant OS · Stack Page
The AI Client Acquisition Stack
for Solo Consultants
A lean operating system for getting leads, following up, onboarding clients, and removing admin drag — without hiring a VA.

The problem
Solo consultants lose revenue in the gaps.
Not in the work itself — in the space between the work. Inconsistent follow-up, messy intake, slow proposals, and manual onboarding that eats 10+ hours a week.
Leads fall through
A discovery call goes well. You say you'll follow up. Life happens. Two weeks later the prospect hired someone else.
Onboarding is manual
Every new client triggers 15 different manual tasks — contracts, intake, scheduling, kickoff prep — all done by you, every time.
Admin eats billable time
Most solo consultants spend 20–30% of their time on non-billable admin. That's one full day a week not being paid.

Workflow first. Tools second.
Most tool stacks are built backward — people pick tools and then figure out the workflow. The Consultant OS starts with the seven workflow problems, then assigns the right tool to each one.
Leads arrive from multiple sources with no consistent capture or follow-up system. Most are lost within 72 hours of first contact.
HubSpot captures every lead. Make triggers immediate welcome email + nurture sequence. Zero manual follow-up required.
Scheduling discovery calls takes 5–8 emails. Prep for each call requires manual context reconstruction. You show up half-ready.
Calendly eliminates scheduling. Claude generates a 2-minute call brief from the intake form. You show up fully prepared.
Proposals take 3–4 hours to write, and half that time is staring at a blank document trying to structure the thing.
Claude drafts from your discovery notes and a stored template. First draft in 90 seconds. Review and send in 20 minutes.
New client signs → 15 manual tasks begin. Contract, intake form, payment, kickoff invite, project setup. All done by hand, every time.
Make automation fires all 15 tasks within 60 seconds of contract signature. You don't touch it. Ever.
Project management, research, deliverable drafting, and client communication all compete for your attention simultaneously.
Notion tracks every project. Claude handles research and draft deliverables. Your time goes to judgment and relationships.
Post-project follow-up is inconsistent. Some clients get a thank-you. Most don't. Referrals that would come from a good follow-up never materialize.
Kit sequence fires 30 days post-project: results check-in, referral ask, and next-engagement offer. Runs without you.
Past clients stop hearing from you. Newsletter goes unsent. Relationship cools. Repeat business doesn't happen because you weren't top of mind.
Regular newsletter and quarterly check-in sequence keeps every past client warm. Zero ongoing effort after initial setup.
The stack
Six tools. One operating system.
Each tool has one job. Together they form a closed loop from first contact to repeat client.

The workflow
From first contact to repeat client.
What the OS looks like when it's running. Each step is mostly automated after initial setup.
Lead enters your system
Via landing page, LinkedIn, referral, or cold outreach. They fill a short intake form or book a discovery call directly.
Automated nurture begins
A welcome sequence fires immediately — 3–5 emails over 2 weeks sharing your POV, case studies, and a clear next step.
Discovery call
Claude preps a call brief from the intake form in 2 minutes. You show up informed. Notes go into Notion automatically after.
Proposal sent within 24 hours
Claude drafts from your notes and template. You review and refine. 3 hours becomes 30 minutes.
Client signs → onboarding triggers automatically
Contract signed → Make fires: welcome email, onboarding form, payment link, kickoff invite. All within 60 seconds. You don't touch it.
Delivery and retention
Project lives in Notion. AI handles research, summarization, and draft deliverables. Regular check-in cadence runs via Calendly.

You don't yet have a clear offer, a defined audience, or a repeatable service. The OS amplifies what's already working — it can't replace a business model. Fix the fundamentals first, then automate the machine.

Ready to fully automate?
Add Make once you have consistent lead flow. Add Kit when you're building a nurture system. Don't automate chaos — automate what already works.
