 Our [mission](../mission) is to cultivate an economy of gratitude, generosity,
 and love. Our [values](../brand/) additionally include honesty, kindness,
-directness, safety, and optimism. We've identified two audiences that
-potentially share our mission and values:
-
- 1. People who want to tip their friends and family.
-
- 1. People who want to run an open company.
-
-Let's unpack that.
-
-We recognize two basic kinds of actors in our economy: individuals (people) and
-groups (organizations, companies, teams, projects, etc). The relationships
-between these two kinds of actors give rise to three "moments" or experiences
-on which Gratipay is built:
-
- 1. a moment of "pure" generosity and gratitude, when an individual gives a
-    small, altruistic, no-strings-attached gift, which another individual 
-    receives; and,
-
- 2. a moment of "calculated" generosity and gratitude, when: 
-
-    <ol style="list-style: lower-alpha"> 
-     <li>an individual or group pays money (as a customer) to a group; or,</li>
-     <li>an individual or group takes (as a staff member or division) or receives
-       (as a contractor or vendor) money from a group.</li>
-    </ol>
-
-These three moments lead to three levels to our product:
-
- 1. We are a marketplace for small, no-strings-attached gifts between
-    individuals.
-
- 2. <ol style="list-style: lower-alpha"> 
-     <li>We are a marketplace for pay-what-you-want goods and services.</li>
-     <li>We are a marketplace for take-what-you-need work.</li>
-    </ol>
-
-Which is to say that Gratipay is three marketplaces in one ... aaaaand that's a
-lot of marketplaces. But what could we cut? Without Marketplace 1, we lose the
-"pure" moment that authenticates and validates and animates the rest. Without
-Marketplace 2b we lose the ability for normal people to find a living within
-our economy, and without Marketplace 2a we lose the ability for groups to
-sustain themselves and provide a living for individuals. It seems that we have
-to build a triple marketplace in order to achieve our mission.
-
-As a triple marketplace we serve "buyers" and "sellers" on both sides of all
-three exchanges. For each marketplace there is a primary customer of ours, who
-is the initiator or active partner in each exchange. They bring with them their
-passive partner, who is then our secondary customer. Our primary customer for
-each marketplace is:
-
- 1. the individual giver
-
- 2. <ol style="list-style: lower-alpha"> 
-     <li>the group receiver (company or organization collecting payments or donations)</li>
-     <li>the group giver (company or organization offering work)</li>
-    </ol>
-
-
-Our secondary customer for each marketplace is:
-
- 1. the individual receiver
-
- 2. <ol style="list-style: lower-alpha"> 
-     <li>the individual or group giver (customer)</li>
-     <li>the individual or group receiver or taker (contractor, vendor, staff member, or division)</li>
-    </ol>
+directness, safety, and optimism. Our primary audience is people who want to
+run an open company.
