Before we show you Flume
It has been proven.
Calm e-ink hardware. AI that listens. Two markets, already won.

00 The thesis
Flume is two proven ideas in one device.
AI recorders that capture meetings.
E-ink devices built for focus.
01 Plaud · AI recorder
From Kickstarter to two million devices.
2M+Started with a $1.1M Kickstarter in 2023. Now $100M in software revenue a year.
Pocket02 Pocket · AI recorder
$100M run-rate in eight months.
200K+Devices sold since October 2025, by a team of about twelve.
03 The signal
Big tech is buying in.
Amazon · July 2025
Meta · December 2025
Granola · March 2026
04 reMarkable · E-ink
A paper tablet that became a unicorn.
$434MRevenue in 2024, profitable. Started with its own pre-orders in 2016.
05 Boox · E-ink
Profitable every year, now going public.
1.2MMonthly users on Boox’s own software. Filing for a Hong Kong IPO.
06 Xteink · E-ink
A $69 reader that outsold the Kindle.
#7On Amazon’s e-reader chart, ahead of the Paperwhite. Buttons only, one job.
07 Side by side
Five companies. One shape.
| Company | The one job | How they started | Today |
|---|---|---|---|
| Record, one press | Kickstarter | 2M+ devices |
| Pocket | Hear the room | Concept video | 200K+ devices |
| Think on paper | Own pre-orders | 3M+ devices |
| Read and write on e-ink | A small pen reader | IPO filing |
| Read, nothing else | A $69 price | Top 10 on Amazon |
08 The clock
And it is getting faster.
Time from first shipments to scale. The first wave of e-ink took years. The AI wave takes months.
09 The pattern
What they all got right.
- 01
One job, done well.
Plaud records. Xteink reads. reMarkable writes. Each one says no to everything else, and that is why people trust it.
- 02
Prove it small first.
A Kickstarter, a pre-order page, a concept video. Every one of them showed demand before building at scale.
- 03
The device opens the door. Software stays.
Half of Plaud’s users pay for AI. reMarkable has over half a million subscribers. The hardware is how the relationship starts.
- 04
Small teams, real results.
Pocket did it with about twelve people. Plaud did it on about $5M of outside money. Focus beats headcount.
So the question is not whether this works
It is how Flume is different.
