Founding PM for Startups
GTM strategy, MVP roadmap, business development, fundraising support, user and system flows, and financial modeling. Scoped per engagement.
Product strategy consulting
Product clarity for teams that can’t afford to guess.
Hanbit gives startups and growing tech companies a unified product vision — strategy, roadmap, and execution — so every bet points the same direction.
What you leave with
An MVP scoped to what you can actually ship
Not the version that needs a team you don't have.
A roadmap your team can actually build
Sequenced against real constraints, not a wish list.
A financial model that survives diligence
Assumptions an investor can pull on without it collapsing.
Positioning that survives the first question
“Why you, why now” — answered before anyone asks.
Services
Scoped to where you are — from one deliverable to founding PM.
PM for Startups & SMBs
Contract product management for a defined milestone, deliverable, or time period. Strategic market positioning, strategy, and roadmaps for a specific initiative.
AI Transformation Strategy
Start with the business, not the tech. Hanbit assesses where AI fits your market position — and where it doesn't — then refines the positioning and builds the roadmap. If AI isn't your bottleneck, you'll hear that too.
À La Carte Deliverables
A single deliverable done right: financial models, investor decks, MVP roadmaps, and more.
Not sure which fits? Tell me where you are and I’ll point you at the right one.
Approach
Hired to have an opinion, not to run a process.
Three constants — whatever the scope.
Start where you actually are
Most product consulting assumes you already have a product, a team, and a roadmap. Plenty of founders don't. Hanbit works from zero — scope the MVP, build the model, write the narrative — or steps into an existing roadmap mid-flight.
Advice from someone who shipped
Ten years shipping product in adtech — Director of Product at a US programmatic ad exchange, through its $120M acquisition, and ML forecasting across roughly $1B of inventory before that. Every call comes from someone who has built the thing and lived with the result, not read about it.
See it the way your investors will
Hanbit sits on both sides of the table — building product, and sourcing and diligencing early-stage deals for VC organizations. Your product gets pressure-tested the way an investor will test it, before they do.
About Hanbit
Built by an operator who shipped the thing, not just the deck.
Hanbit is the consulting practice of Jinhwa C. Rustand — a product leader with 10+ years in adtech. Most recently Director of Product at a leading US programmatic ad exchange — owning the full exchange, DSP and SSP, reporting to the CEO — through its $120M acquisition. Earlier, built ML forecasting across roughly $1B of digital ad inventory at a major media and entertainment conglomerate.
Today that means founding-PM work with early-stage startups, advising on pre-seed fundraising and GTM, and investment operations and partnership work for VC organizations — sourcing and diligencing early-stage deals from the other side of the table.
Which means Hanbit sees your product the way your investors will — because it evaluates companies like yours every week.
