How We Built It: $30K/month Mobile App
Starter Story
Nov 18, 2025
Eyal and Yahli Hazan built an app that was stuck at $2K MRR for months. The problem? Their app simply wasn't good enough... So they spent 4 months rebuilding it and after relaunching, they hit over $10K MRR in one week. This video breaks down why distribution isn't everything and how to optimize your product based on data.

This
is
Eyal
and
Yali
two
college
students
who
built
an
app
that
at
first
crushed
it
with
downloads
We
were
averaging
20
downloads
a
day
right
off
the
bat
But
they
had
a
problem
Almost
nobody
stayed
after
the
trial
ended
Their
conversion
was
horrible
If
your
product
is
shit
nobody's
going
to
buy
it
They
were
stuck
at
2
000
a
month
and
they
had
no
idea
what
to
do
So
they
decided
to
scrap
everything
and
go
back
into
the
cave
So
we
shut
down
all
marketing
and
spent
four
months
completely
rebuilding
from
scratch
After
doing
this
on
their
second
try
they
hit
30
000
MRR
in
just
10
weeks
And
I
brought
Eyal
and
Yali
onto
the
channel
to
share
with
me
exactly
what
they
changed
In
this
video
we'll
dive
into
why
distribution
does
not
matter
if
your
product
sucks
how
to
identify
if
your
product
is
actually
doomed
from
the
start
and
Eyal
and
Yali's
exact
playbook
for
building
a
product
that
actually
makes
money
in
2025
This
one
is
a
must
watch
for
anyone
building
apps
right
now
I'm
Pat
Walls
and
this
is
Starter
Story
Yali
and
Eyal
welcome
to
the
channel
Tell
me
about
who
you
are
what
you
built
and
what's
your
story
Hey
I'm
Eyal
Hey
Pat
I'm
Yali
And
together
Eyal
and
I
built
an
app
that
makes
30
000
a
month
We
launched
it
around
a
year
ago
We
got
stuck
at
1
000
to
2
000
MRR
We
took
four
months
to
rebuild
it
and
then
it
skyrocketed
Okay
before
we
get
into
what
you
guys
changed
that
skyrocketed
your
app
I
do
need
to
understand
what
is
your
app
and
what
does
it
do
We
built
PropDVT
which
is
basically
a
sports
betting
analytics
platform
that
uses
our
machine
learning
algorithm
to
hit
the
most
picks
So
users
get
access
to
our
models
and
get
to
analyze
their
own
picks
or
look
through
all
the
pre
analyzed
bets
that
we
scan
every
single
day
We
do
about
30
000
a
month
and
we've
had
over
40
000
downloads
and
over
3
000
paying
customers
We
have
a
48
conversion
to
trial
rate
And
for
every
user
that
downloads
PropDVT
we
make
around
3
30
What
did
the
build
process
look
like
before
you
went
and
got
onto
the
app
store
We
spent
like
five
months
building
the
first
version
of
PropDVT
It
was
taking
a
while
to
build
particularly
because
Chachapiti
was
still
new
Eventually
in
the
middle
of
the
NFL
season
last
year
that's
when
we
started
launching
And
that's
when
we
sort
of
figured
out
that
our
product
market
fit
wasn't
exactly
what
we
wanted
All
right
guys
Black
Friday
is
in
just
a
couple
of
days
And
as
you
might
already
know
we
are
doing
something
huge
at
Starter
Story
I
do
not
want
you
to
miss
out
on
one
of
the
best
deals
we've
ever
done
because
last
year
our
Black
Friday
deal
sold
out
in
just
two
hours
And
once
people
hear
about
this
year's
deal
I'm
positive
it's
going
to
sell
out
even
faster
So
if
you
don't
want
to
miss
out
on
that
just
go
to
starterstory
com
slash
Black
Friday
or
hit
the
first
link
in
the
description
and
we'll
notify
you
as
soon
as
the
deal
is
live
Spots
are
going
to
be
very
limited
for
this
So
what
are
you
waiting
for
All
right
let's
dive
into
the
interview
Okay
so
you
get
this
idea
up
on
the
app
store
You're
ready
to
go
How
do
you
actually
get
users
for
this
app
How
many
users
did
you
get
And
kind
of
where
did
you
get
this
app
to
up
to
that
point
The
moment
we
got
it
on
the
app
store
we
had
a
really
good
base
of
influencer
marketing
I
had
worked
with
other
really
successful
app
founders
before
and
then
I
kind
of
saw
the
rise
of
the
initial
influencer
marketing
hype
We
start
spending
a
few
thousand
dollars
on
influencer
marketing
to
see
how
many
downloads
we
would
get
for
the
money
spent
And
we
were
able
to
get
around
20
downloads
a
day
which
converted
around
5
to
10
users
a
day
day
because
we
had
really
high
conversion
from
downloads
to
free
trials
And
we
couldn't
really
push
past
1
to
2K
MRR
so
we
kind
of
noticed
that
there
was
something
critically
wrong
with
our
app
despite
seeing
a
lot
of
hype
around
it
That's
one
of
the
reasons
why
I
wanted
to
bring
you
guys
on
the
channel
which
I
think
is
super
interesting
You
kind
of
had
the
distribution
figured
out
but
you
noticed
that
even
though
you
kind
of
knew
how
to
crack
this
code
you
really
couldn't
get
the
app
past
1
to
2K
MRR
How
did
you
solve
that
problem
How
did
you
eventually
build
an
app
that's
making
over
30
000
a
month
We
realized
that
what
our
customers
actually
wanted
was
just
to
be
given
the
right
answers
to
the
test
and
not
necessarily
go
through
the
sportsbooks
and
input
their
bets
bets
and
check
for
themselves
if
it
was
a
good
bet
or
not
So
we
took
four
months
to
rebuild
the
app
no
marketing
just
engineering
and
design
work
And
we
launched
the
new
version
on
April
15th
where
we
were
at
1
700
MRR
and
around
15
downloads
a
day
This
is
after
a
few
months
of
no
marketing
The
next
month
we
go
all
in
on
marketing
again
for
the
NBA
playoffs
And
all
of
a
sudden
our
conversion
rate
to
paid
was
over
50
Two
and
a
half
months
later
we
hit
our
peak
of
40K
MRR
and
2
000
downloads
in
a
single
day
See
even
though
Eyal
and
Yali
had
the
distribution
figured
out
from
day
one
they
still
had
a
huge
problem
The
product
simply
was
not
good
enough
So
they
spent
four
months
rebuilding
it
And
that's
when
everything
changed
This
is
exactly
why
learning
how
to
build
with
AI
is
so
powerful
When
you
know
how
to
build
and
what
to
change
you
can
iterate
fast
and
optimize
based
on
what
your
users
actually
need
And
this
is
exactly
what
we
teach
inside
Starter
Story
Build

our
live

where
you
will

how
to

and
launch
your

using
AI
tools
in

You'll
learn
how
to
think
like
a

developer
and
how
to
use
AI
to
build
real
working
products
just
like
Eyal
and
Yali
Our
next
accelerator
is
starting
soon
So
if
you're
ready
to
start
building
if
you're
ready
to
get
off
the
sidelines
head
to
the
first
link
in
the
description
to
claim
your
spot
All
right
now
let's
get
back
to
the
video
Okay
so
you
guys
realize
that
no
offense
there's
a
better
way
of
saying
it
but
you
had
a
bad
product
or
the
product
wasn't
simple
enough
but
it
took
you
guys
a
while
to
realize
this
For
anyone
that's
watching
this
right
now
who's
built
something
or
thinking
about
building
something
what
would
be
your
advice
on
how
to
figure
out
how
to
build
a
great
product
What
are
the
actual
things
you
should
be
doing
every
day
to
avoid
this
mistake
or
at
least
fix
it
if
it
happens
happens
The
most
important
thing
is
to
have
an
extremely
humble
attitude
about
your
product
If
your
product
is
shit
then
simply
it's
not
going
to
work
Like
nobody
will
buy
it
Using
analytics
platforms
like
PostHog
and
simply
talking
to
enough
users
you
see
that
there's
a
pattern
of
human
behavior
that
doesn't
align
with
how
the
app
is
designed
For
example
on
Superwall
we
saw
that
a
lot
of
people
were
converting
to
the
trial
but
then
nobody
was
staying
after
Like
what
does
that
really
say
about
your
users
What
it
means
is
that
your
users
think
this
is
a
great
idea
think
that
this
could
add
a
lot
of
value
to
their
life
but
when
it
actually
comes
to
using
the
app
it's
not
the
experience
that
they
were
hoping
for
These
signals
is
what
a
good
product
manager
should
do
And
it's
going
to
mean
that
your
business
model
will
work
a
lot
better
when
you
make
sure
that
your
product
actually
best
fits
your
users
Based
on
all
you
guys
learnings
I
would
love
if
you
guys
gave
me
sort
of
the
playbook
for
how
to
build
a
great
product
specifically
how
to
build
a
great
app
in
2025
Can
you
break
that
down
for
me
Step
one
really
understand
who
exactly
you're
building
for
and
what
their
pain
points
are
Step
two
is
listen
to
your
data
We
became
obsessed
with
the
numbers
Again
two
numbers
that
stuck
out
for
us
45
conversion
to
trial
but
then
only
13
conversion
from
trial
to
paid
What
does
that
mean
Everybody
wondered
what
we
were
selling
but
the
product
was
shit
Step
three
obsess
over
analytics
So
if
you
know
your
users
are
falling
off
during
onboarding
then
you
know
which
screens
aren't
selling
your
app
well
enough
If
you
track
all
of
the
feature
clicks
on
your
app
you
can
identify
your
app's
most
compelling
value
proposition
and
then
communicate
that
in
your
marketing
Any
way
that
you
can
see
what
your
customers
is
actually
doing
is
a
massive
advantage
Step
four
once
your
app
is
built
the
real
challenge
is
scaling
it
effectively
The
smartest
way
to
grow
today
is
through
influencer
marketing
Their
followers
engage
deeply
and
convert
faster
when
they
see
someone
that
they
admire
using
your
product
Another
great
advantage
of
organic
social
media
marketing
is
the
chance
to
go
viral
So
for
example
probably
our
70th
video
to
ever
come
out
hit
600
000
views
and
that
raised
our
ARR
from
around
8K
to
38K
in
about
three
days
And
that's
really
the
power
of
influencer
marketing
One
video
can
seriously
change
your
entire
business
Okay
cool
Well
thanks
for
sharing
that
demo
That
was
awesome
On
a
similar
note
I'm
curious
what's
the
tech
stack
behind
this
app
How
did
you
build
it
And
then
also
like
what
tools
do
you
use
on
a
daily
basis
We
built
this
on
a
React
Native
repo
We
mostly
use
a
lot
of
TypeScript
and
Python
for
our
machine
learning
algorithms
along
with
our
automated
fetching
for
all
of
the
data
Additionally
we
have
a
giant
database
which
we
store
on
Neon
and
tools
for
analytics
We
use
Revenue
Cat
and
Superwall
for
revenue
dashboards
and
paywalling
What
are
the
costs
or
the
profit
margin
around
running
an
app
like
this
Yeah
so
the
costs
are
basically
0
20
per
conversion
to
Superwall
typically
1
to
Revenue
Cat
We
pay
for
a
lot
of
data
APIs
to
get
all
the
real
time
sports
data
every
single
day
and
that
costs
about
100
a
month
We
also
spend
about
10
a
month
on
our
Neon
database
to
make
sure
we
have
the
bandwidth
for
all
the
calls
that
we
make
LLM
costs
cost
about
20
a
month
and
the
cost
is
constantly
going
down
Marketing
is
about
10
000
a
month
All
in
all
we
have
roughly
50
margins
at
the
end
of
the
day
Okay
cool
Well
thank
you
for
sharing
that
being
transparent
around
the
numbers
A
lot
of
people
who
watch
us
really
appreciate
that
The
last
question
that
I
have
for
both
you
guys
a
lot
of
people
watching
this
want
to
build
apps
like
you
want
to
learn
about
distribution
and
product
What
would
be
your
advice
to
people
that
are
starting
out
right
now
trying
to
do
this
thing
online
build
apps
and
make
money
Biggest
piece
of
advice
I
could
give
is
have
a
co
founder
who
you
will
be
able
to
lean
on
and
that
will
be
able
to
lean
on
you
when
things
get
hard
As
an
entrepreneur
be
honest
with
yourself
and
scientific
about
whether
what
you're
working
on
has
enough
demand
If
you
prove
it
to
yourself
that
it's
worth
the
time
investment
that
you
will
put
in
struggling
it
will
be
an
order
of
magnitude
easier
to
prove
it
to
others
to
both
investors
and
future
team
members
Beautiful
Well
thank
you
Eyal
and
Yali
for
coming
on
What
you
built
is
awesome
Congratulations
You
guys
are
awesome
Pat
thanks
so
much
We
absolutely
love
Starter
Story
It's
so
cool
to
get
on
Appreciate
it
Pat
We
had
a
great
time
What
I
thought
was
interesting
about
their
story
is
usually
you
get
the
product
right
but
you
don't
have
the
distribution
figured
out
For
them
they
had
the
distribution
figured
out
but
they
didn't
get
the
product
right
And
I
think
that's
cool
because
it
really
goes
to
show
that
you
have
to
have
both
figured
out
if
you
actually
want
to
build
something
that
can
last
This
is
exactly
why
we
launched
Starter
Story
Built
where
we
will
help
you
take
your
idea
and
turn
it
into
a
real
app
using
only
AI
tools
So
if
you're
ready
to
finally
build
that
idea
get
it
out
of
your
head
and
get
it
into
the
real
world
we'll
head

All
right
guys
that's

Thank
you
for

I
hope
you
enjoyed
it
