    for founders solving the chicken-and-egg problem

    sound familiar?

    the platform paradox

    🐔

    chicken-and-egg

    Sellers won't join without buyers. Buyers won't join without sellers. Stuck.

    🏗️

    overbuilding

    You built the whole platform before getting a single user. Now nobody wants it.

    📉

    ghost town

    You launched. Got a few signups. Now it's a graveyard.

    💸

    no unit economics

    You have no idea if your take rate works. Just hoping it'll scale.

    🤔

    supply vs demand focus

    Should you focus on supply or demand first? You've been flip-flopping.

    ⏰

    massive scope

    Marketplaces are complex. The scope feels overwhelming for a side project.

    your roadmap

    your path from idea to traction

    1

    constrain your initial market

    Validation

    Don't be Uber for everything. Start hyper-local or hyper-niche.

    2

    solve one side manually

    Validation

    Seed supply yourself. Be the first seller. Do things that don't scale.

    3

    get your first 10 transactions

    Building

    Match buyers and sellers manually. Prove the core value works.

    4

    build the mvp (finally)

    Building

    Now you know what to build. Create the minimum viable platform.

    5

    hit liquidity in one niche

    Launching

    Enough supply and demand that transactions happen without you.

    6

    expand strategically

    Launching

    Adjacent markets, new geographies. Grow methodically.

    why we make you constrain first

    Every successful marketplace started small. Uber was black cars in SF. Airbnb was air mattresses in one city. Constraint is your superpower.

    who it's for

    this is for you if...

    You're building a marketplace or platform

    You're stuck on the cold-start problem

    You're building on the side while employed

    You want traction, not just a polished product

    not for you if

    You want to build the next Uber without any constraints

    You're not willing to do things that don't scale

    You want someone else to solve cold-start for you

    stop overthinking. start matching.

    your first transaction doesn't need a platform. it needs you.
