The Story of Academia.edu
Richard Price
May 2020
I grew up in the UK, and became interested in philosophy when I was a
teenager. I was interested in questions like: does God exist? Do we have free
will?
I applied to Oxford to study Philosophy, Politics, and Economics, and got
in to St Catherineâs College. I then stayed on to do a Masters in philosophy,
and then a PhD (which Oxford calls a âD.Philâ). For most of my PhD, I was
at All Souls College, where I was a Prize Fellow.
Aside from philosophy, my other passion in life is entrepreneurship. I started
four companies alongside my PhD: Richardâs Banana Bakery, which was a cake
company selling banana cakes to offices in London; Dashing Lunches, a sandwich
company selling sandwiches to offices in London; LiveOut, which was a database
of student rental properties in Oxford; and PeopleRadar, which was a photo-
rating app on Facebook.
1 Idea
The fifth company was Academia.edu. As I was finishing my PhD, I decided I
wanted to have a homepage where I could say âthis is who I am; this is what
I have been working on; here are my papers.â At the time, Oxford offered a
few megabytes of space for personal websites, and you had to write your own
HTML, and FTP files to the server yourself.
I remember thinking âthere should be a one-click way of creating a homepage,
and uploading papers. Having a homepage shouldnât require technical ability.â
I asked a few of my fellow graduate students, and they felt the same way.
We all wanted homepages for a couple of reasons. One was that the journal
system is slow: it takes âź12 months to get a paper published in a journal. The
second reason was that the journal system puts papers behind paywalls: it costs
$40 on a journal site to download a single paper. Homepages allowed you to get
your papers out quickly, and make them available for free.
I wrote a long business plan (âź80 pages), traveled to and from London to
technology networking events, where I would meet investors, and ask them for
introductions.
I raised $600,000 from London-based investors, and moved to San Francisco.
Ben Lund, a software engineer from the UK, joined a few months later. With a
1
few others, we launched Academia.edu in September 2008.
2 Growth
In the early days, what mattered most of all was growth: growth in users and
papers uploaded. In the first few months, we were growing at a linear rate.
Some days 37 users would join, the next day 42, the next day 38. We made it
to 50,000 users a year later, and a friend of mine posted on my Facebook wall
âCongratulations; hereâs to 500,000 users.â I remember thinking âwow, that is
a lot. At a linear rate, that is going to take 10x the amount of time it has taken
so far.â
We started to figure out exponential growth, and we got to 500,000 users,
and then quickly to 1 million users. Today 125 million users have joined
Academia.edu, and around 140,000 people join Academia.edu each day.
3 Mission
The mission of Academia.edu is to accelerate the worldâs research. Our goal
is to speed up research in every domain - finding a solution to climate change;
finding cures for diseases; evolving artificial intelligence. We want to accelerate
research in all these fields, and others too.
There are four pillars to Academiaâs mission.
3.1 Open Access
The first pillar of the mission is open access. Academiaâs goal is to ensure that
every paper, ever written, is on the internet, available for free. 22 million papers
have been uploaded to Academia.edu. We think there are âź100 million papers
ever written, so we are âź20% of the way there.
3.2 Distribution
The second pillar of the mission is distribution. Academiaâs goal is to build the
fastest and most relevant paper distribution system in the world.
Today Academia.eduâs algorithms make about 20 million paper recommenda-
tions a day.
3.3 Peer Review
The third pillar of the mission is peer review. Academiaâs goal is to provide
signals regarding the trustworthiness of papers, and the trustworthiness of in-
dividual claims within papers, on Academia.edu.
Over 65 million people visit Academia.edu each month. Most of them are
not experts in the areas of the papers that they are reading. They might read a
2
sentence such as âHydroxychloroquine has been shown to help patients suffering
from Covid-19â. They may wonder to themselves âWhat do people in the field
think about this claim?â
At the paper level, we have a system called PaperRank. A paper can be
recommended by one of Academia.eduâs âź20,000 editors. A paperâs PaperRank
is a function of how many recommendations it has received, weighted by how
well recommended the recommender is.
In the future, we want to build more peer review tools, particularly in the
area of allowing people to understand expert consensus around individual claims.
3.4 Formats
The fourth pillar of the mission is formats. Academiaâs goal is to enable the
sharing of knowledge in a variety of formats. There are instances of knowledge
such as data, and code, that donât fit into the traditional PDF format. There
are formats such as video, which some people prefer for learning. Not everyone
has two hours to read a 10,000 word PDF. Some people want a compressed
version of the key ideas.
Academia recently launched a feature called âSummariesâ. We trained a ma-
chine learning algorithm on our corpus of 23 million papers, and now summaries
of âź700 words in length are available for any paper on Academia.edu.
In the future, we would like to enable the sharing of other formats such as
data-sets, code, video, and other kinds of textual formats.
4 Plan
The plan for Academia is to build these pillars in steps.
1. Build an open access platform.
2. Build a distribution system.
3. Build a peer review system.
4. Build a system for sharing new formats.
We have built an open access platform (step 1). We are currently on step 2
of Academiaâs plan: building a distribution system.
5 Guiding Philosophy
Our guiding philosophy is that people want:
⢠Research to be free
⢠Research that is relevant to be sent to them
3
⢠Signals that help them evaluate the truth/falsity of what they are reading
⢠Research to be presented in the right format, for easy comprehension
Academia.eduâs goal is to make that vision a reality. The end result is:
⢠Research is accelerated: research towards solving the worldâs problems is
accelerated.
⢠Research is democratized: everyone has access to it.
6 Business Model
Academiaâs business model is a premium subscription service. People can pay
$100 a year to upgrade to a premium account. This includes features such as:
⢠Mentions (knowing who is mentioning you)
⢠Bulk Download (being able to download lots of PDFs at once)
⢠Advanced Search (searching the full-text of papers on Academia.edu)
⢠Summaries (the summaries product mentioned above)
⢠Grants (accessing a database of grants on Academia.edu)
⢠and other features.
225,000 people have become Premium subscribers. The company is prof-
itable. The company has 53 people, most of whom are software engineers,
product managers and designers. Everyone is based in San Francisco.
7 The Surprising Reach of Academic Research
The most surprising thing I have learned, since starting Academia.edu, is how
large the interest in academic research is from beyond the academic world.
Academia.edu has over 65 million visitors each month. By our calculation, there
are about 17 million academics in the world (graduate students and faculty).
A reasonable fraction of academics visit Academia each month, but approxi-
mately 85% of Academia.eduâs monthly visitors are not academics. They are
professionals: lawyers, engineers, teachers, nurses, architects. Every profession
is represented.
When downloading a paper, someone can explain what sparked their interest
in the paper. We call these âreasons for downloadingâ. Here are a few reasons
for downloading from professionals. These reasons speak to the way in which
research is brought into the work-place:
4
A chemical engineer from the U.S. wrote âI was viewing this article in an
attempt to better model the crystallization reactor for a phosphoric acid pro-
duction plant. Iâm particularly trying to find operating temperatures and pres-
sures.â
A farmer in Africa, downloading a paper on water conservation, wrote âI
farm in the Sahara desert so conserving water is important to me, and I want
to find out more about how to re-use our limited water to feed myself and my
animals.â
A teacher downloaded a paper called âThe Pen is Mightier than the Key-
boardâ, and wrote as their reason for downloading âThe kids I teach are in a
K-8 school. The school says pencils will be banned next year. I am looking for
research to change that decision.â
8 The Beginning
We have begun the project of making research open; distributed; verified; and
available in new formats. I am proud of what Academia.edu has achieved so
far. Most of the work lies in the future, and I find that inspiring.
