Sound familiar?
Most founders call me at one of three moments.
You just closed a round.
The money's in the bank. Now you need a plan and a shipped product before the next board meeting.
You've been building without a PM.
Engineers are shipping, but nobody owns the roadmap, the specs or the tradeoffs.
A competitor is racing you to market.
You need an MVP scoped, specced and in sprints this month, not next quarter.
What I do
Five services, one operator. Most engagements start with product management and pull in the rest as the product needs it.
- Product ManagementRoadmaps, MVP launches, PRDs, product lifecycle
- Design & UXWireframes, prototypes, user research, usability testing
- Sales & MarketingGTM strategy, funnel optimization, A/B testing, value prop
- Analytics & DataDashboards, reporting, analytics strategy, predictive analytics
- StrategyGrowth planning, pricing, fundraising
No dev team? I'll bring one.
I work with a small network of developers I've shipped products with. When you need engineers, I bring them in and stay on as your product lead, so you get one point of contact instead of a separate agency to find and manage.
Ask about a build teamAI workflows for your product and dev teams
I set up the AI workflows I run on my own engagements across the whole product lifecycle, so your team moves from requirements to release with less busywork at every step.
- Requirement gathering
- Design
- PRD & ticket drafting
- Development
- QA
- Release

I'm Guill Trujillo. I've built product inside startups, not just advised them.
Operator, not advisor
I've shipped at LendingClub before and after its IPO, at Lenda on the way to $2M MRR, and at hopps, which I co-founded.
AI-native
I work in Claude Code/Design, Cursor and Codex, the tools your engineers use, so specs turn into shipped code faster.
Full stack, one person
Product, design, GTM and data from one senior operator, so nothing gets lost in hand-offs.
Stanford-trained, startup-tested
