Product Builder
You know what you want built. I build it. Using AI-assisted development I ship faster and cheaper than any agency you'd hire.
Why founders choose Product Builder
One person. Full accountability.
No dev team to manage. No communication chain to maintain. I own the build from scope to launch and I'm accountable for the outcome.
AI-assisted means faster and cheaper.
What a four-person agency takes six months to build I can deliver in half the time at a fraction of the cost. Zenpost is the proof.
You stay in the loop without being in the weeds.
Weekly demos and updates. You see real working software every week. No surprises at launch.
Scope discipline built in from day one.
I wrote the scope document. I know exactly what's in V1. I protect the launch date because I designed the boundaries.
The build starts with the scope. Not the code.
Before anything gets built we agree on exactly what's being built. Feature list, user flows, V1 vs V2, technical architecture. All of it locked before I write a line of code.
Most agencies skip this because they want to start billing. I don't skip it because building the wrong thing costs everyone more than getting the scope right upfront. Ask me how I know.
I didn't learn this from YouTube. I built a platform solo and it's live right now.
Zenpost is an AI-powered marketing platform with a website builder, social scheduler, blog editor, CRM, email tools, booking pages, and lead capture. Built it solo using AI-assisted development in 8 months. It runs in production today with real users.
A traditional agency would've quoted you 18 to 24 months and $500K for the same thing.
That's the methodology I bring to every client build.
Every engagement has a finish line. On purpose.
The last week is the handoff: written guidelines, a workshop with your team, and a 30-day check-in. Then I'm gone, and your team owns the work without me in the loop.
I don't sell drift. If you need a full-time leader after we wrap, I'll help you find them — that's part of the deal, not a separate engagement.
“Dave is amazing! Super easy to work with and an effective collaborator, taking complex problems and developing successful tech solutions.”
How a Product Builder engagement runs.
- 01
Discovery call
30 minutes to understand what you're building and whether the scope and budget are realistic.
- 02
Scope and architecture
Before any code gets written we align on exactly what's being built. Feature list, user flows, V1 definition, technical stack. You sign off before I start.
- 03
Weekly build demos
Every week you see what's been built. Real working software, not mockups. You give feedback, I adjust. No surprises at launch.
- 04
Scope discipline throughout
Every feature request gets evaluated against the agreed V1 scope. Good ideas that aren't in V1 go on the V2 list. That's how the launch date stays real.
- 05
Launch and handoff
When the product hits the agreed launch criteria I deploy it, document the codebase, and hand it over with a 30 day support window for bugs and adjustments.
Is a Product Builder right for you?
This is for you
- You've got a validated idea with a clear scope and you want it built
- You don't want to manage a development team yourself
- You want to move faster and spend less than a traditional agency would charge
- You're comfortable with AI-assisted development as the methodology
- You've got a realistic budget and you want it spent efficiently
This is not for you
- You don't have a defined scope yet (start with Product Consultant)
- You want to hire a team and manage them yourself
- You need enterprise security certifications like SOC2 or HIPAA on day one
- You expect round-the-clock availability
- You're not willing to hold the V1 scope once we've agreed on it
Questions about Product Builder
What does AI-assisted development actually mean?
I use tools like Cursor and Lovable to build faster than traditional development. AI handles the repetitive work. I handle the architecture, the decisions, and the quality. You get real production code, not a prototype.
Is AI-built code reliable enough for a real product?
Zenpost runs in production with real users. That's the answer. Code quality depends on the developer using the tools, not the tools themselves.
What happens if the build takes longer than estimated?
Scope is agreed upfront. If it runs longer because of scope changes you requested that's a separate conversation. If it runs longer because I underestimated the work that's my problem to solve, not yours.
Do I own the code when it's done?
Absolutely. All code, all repositories, all assets are yours at delivery. I retain nothing.
What tech stack do you use?
Depends on what you're building. For most web apps I use modern React-based frameworks with Supabase on the backend. I choose the stack based on what serves the product best long term, not what's easiest for me.

Not sure this is the right fit? Here's what else I do.
Product Consulting
You've got an idea but no real plan. I figure out exactly what needs to be built, what it'll cost, and how long it'll take. You walk away with a scope document your dev team can actually execute.
Product Lead
Your build is already in motion but something's off. I come in as the technical lead, fix the communication, lock the scope, and get the thing across the finish line.
Let's see if we're a fit.
