Tulsa Ecosystem Map

Methodology

How the map is put together, in plain words. The numbers on this page are counted from the map's data each time the site is built.

What is on the map

1,362 entries. Each has a definition, an example and the entries it connects to. An entry can be of more than one kind, so the counts below add up to more than the total.

• Concepts are the terms founders hear, explained for someone starting from scratch.
• Tools are widely used, well-established products. The map describes what each one is and who makes it. It does not rank them.
• Named local entries are the organizations, investors, programs, user groups, schools, places and government bodies of the Tulsa and Oklahoma ecosystem. 312 of them have a recorded Oklahoma base or are marked as relevant to Tulsa (see "What area means").

How entries are chosen

Entries are chosen for a founder in Tulsa learning the ecosystem: the standard terms, the foundational products and the local organizations. Organizations are described neutrally from their own public pages: their sites, their posts and press about them. Nothing about an organization appears without a public page behind it. Pages that back a stated relationship are listed under Sources on the entry; 632 entries list sources.

How connections are chosen

The map has 4,776 connections between entries. 1,315 of them join two named things (organizations, products, programs and the like); the rest involve at least one concept and work as "read next" suggestions.

• A connection between two organizations, including investors, programs, user groups and schools, is shown only when it was announced publicly by an organization involved: on its own site, in its posts or in the press. Nothing discussed only in private appears, even as a hint.
• Some entries note that the Techlahoma Slack discussed or recommended them. Those notes are anonymous and informational, with no names or quotes.
• A missing connection is not evidence that no relationship exists. It means no public announcement was found.

How funding figures are sourced and labelled

122 funding figures appear on 79 entries; 32 of them come from SEC filings. Each figure:

• appears only with a link to the public page that states it: an SEC filing, the organization's own announcement, or press;
• is written as one plain sentence in the source's own terms. An amount reported sold in an SEC Form D filing is not called a round raised, an award is called an award, and a fund target or a first close is not called money raised;
• keeps the source's own date, as precise as the source gives it;
• is never added to other figures, ranked or turned into a total.

The map does not check figures beyond the linked source. Figures are as published by the linked source.

What area means

Area records where a local entry is based, only when its definition or sources say so:

• Tulsa: based in Tulsa (171 entries).
• Oklahoma City: based in Oklahoma City (86 entries).
• Statewide: offices or work in both cities (56 entries). It does not mean every entry in the state.

Entries based elsewhere that still matter to Tulsa founders are marked as relevant to Tulsa and listed with the Tulsa entries (1 entry). Entries that are not local, or whose base is not stated, have no area; they appear only in the "All" lists, never under a place.

Dates

The date at the foot of each entry and list is the date that page's content last changed on the map. It is not the date its sources were last checked. There is no fixed schedule for re-checking sources; a page changes when its data is updated or a correction is made.

Known limits

• Definitions are general and simplified. No lawyer, accountant or outside expert has reviewed them.
• No organization on the map has reviewed or approved its entry.
• Coverage is incomplete. Connections and figures are limited to what was announced publicly and found.
• Products and programs change; check the official site for current details.
• This glossary is plain-language orientation, not legal or financial advice. Before you decide on a company structure, a contract, taxes or a fundraising deal, talk with a lawyer or an accountant.
