Building software got cheap. Judgment did not.
I’m Darren Card, a product and technology leader. Dacard is my applied AI studio. Bring me in full-time as VP of Product, CPO or CPTO, fractionally, or for one project. I decide with you what is worth building, own every call, and show you whether it landed.
Employee #1 and CPTO at Lexful: paying customers in 12 months on a $3M pre-seed. VP Product & Technology at Cognota: the pivot was key to a $5.5M Series A.
Twenty years of work sits behind every call.
Seven companies over twenty years, and the studio’s work now. Open the experience checklist to see what each role covered.

Counts new platforms, as well as new companies.
Every other tick comes from the case pages and the CV.
Titles are as held. At Allocadia and QuickMobile, the Director role was the company’s first product leader.
Agency owner? I co-founded and ran a digital agency, 1999 to 2006. For agencies →
Agents make it. Someone owns it.
I work with 3 types of companies, and I stay with it throughout.
Full-time, fractional, or by the project. A full-time seat is a normal hire. Fractional and project work starts with discovery, the smallest piece of work, and you can stop after it with what it produced. Timing and price are set after it, in writing, and what I build sits in your accounts from day one.
I work full-time as VP of Product, CPO or CPTO at a Series A to C company, or fractionally for AI-native teams that need the operating model before the headcount.
- One owner for the portfolio and the roadmap
- The team, pricing and packaging
- What to build, buy, partner on, or stop
- Taken to the board in plain numbers
For a pilot that demos well and has not shipped: one agent live on real work.
- Evals agreed before launch
- A permission model scoped per role, and per customer where your records are split by customer
- A cost per run, set against what the same work cost before, that your finance team can plan against
- Cognota: first product and technology leader; revenue tripled, and the enterprise pivot was a key element of a $5.5M Series A.
- Lexful: employee #1 to paying customers in twelve months.
- If I take a full-time seat, I stop taking new studio work and hand current work over.
- Lexful: agents in production under a permission model set per customer and per role, an MCP server so outside agents called in under the same rules, and every release gated on evals.
- I still build in Claude Code most working days.
Turn an agency’s best one-off work into a product: packages, pricing, the software under it, and the partners who deliver it. You keep the craft and the client.
- Background: I co-founded and ran a digital agency from 1999 to 2006.
- In progress: a project, not named or described. Business case, packages, pricing and decks delivered; first buyer meetings are under way and nothing has sold, so it says watch.
Busywork goes to Claude; decisions stay with people.
- Small teams: a ready-made setup on Claude for Small Business
- Bigger operations: one system built around how they run
- Each automation scored landed, watch or stalled against a landing brief written before the build
- In progress: a client, not named or described. System design, plan, and prototype delivered; the pilot is next, so it says watch.
The lab ships in public.
Experiments I run on myself first, in public. Read them, try them on your own team, and tell me what they got wrong.
Dacard stays small, so you always work with me.
I run Dacard. I’ve spent twenty years in software product, the last five with engineering too, most recently as employee #1 and CPTO at an AI company. Specialists join by the project, under your access rules and your NDA. You always know whose name is on a decision. The limit is plain: I’m one person, which is why a full-time seat stops new studio work.

Bring the decision you are stuck on.
Thirty minutes, no deck, no fee. If I’m not right for it, I’ll say so and point you somewhere better.
