the short version
every episode now comes with a reddit post.
a title and a body, made of your own sentences from the episode, word for word, with only a few joining words added. it is a draft: put it in your own voice before it goes, because reddit's readers spot a post written for someone. it sits with the other posts on the episode page, beside x and linkedin, on the web and on the phone.
press post to reddit and reddit opens with it filled in. you add the video, you pick the community, you press post.
why reddit gets its own
some of the most honest build-in-public writing anywhere is on reddit. people post their weekly numbers there, their failed launches, the month revenue went backwards.
it is also the least forgiving place to post. a linkedin post pasted into r/buildinpublic reads as marketing within a sentence, and marketing gets downvoted, called out in the comments, or removed by a moderator before anyone sees it.
so the reddit post is not the linkedin post with the hashtags taken off. it is written for people who are building something themselves and want the detail.
what is in it
the same outline as every other post underway writes, so the story is the same wherever it lands:
- a title that says which episode it is and what happened, plainly, the way a person titles their own update
- why a stranger should care, in two or three sentences
- what actually happened, with the real numbers and the real failures wherever you said them
- a short list of what else the episode covers, in the order it came up
- who it is for
what is not in it: links, hashtags, the name of the app it was made with, and anything that reads like a pitch. the people reading can tell, and the moderators remove it.
like every post, it is written from the transcript. no number you did not say, no outcome that did not happen. change any line in the box before it goes; it saves as you type and never touches the cut.
why there is no connect button
youtube, linkedin, tiktok, instagram and x are connected once, and the episode page posts to them for you. reddit is not, for two reasons.
the first is reddit's. since november 2025 every new app needs reddit's written approval before it may use the api at all, and a commercial one needs an agreement on top. it is not a switch we can turn on.
the second is ours. every subreddit sets its own rules: one allows a project post once, one only in a weekly thread, one wants a flair, one wants your account to be a month old. an app posting the same shape of post into communities it has not read is how an app's posts become spam, and how a founder's account gets banned. that is not a risk worth taking to save one tap.
so the hand-off is deliberate. underway writes the words. reddit's own page opens with the title and the body filled in, in r/buildingonunderway, and you can pick another community there. the words go on your clipboard too, in case reddit drops them when you switch to the video tab.
post the video, not a link
download the episode and add it on reddit's video tab. a video uploaded to reddit plays in the feed as people scroll. a link to somewhere else gets scrolled past, and in a lot of communities it gets removed.
the episode already carries made with underway in the corner. that is the only mention it needs.
how to use it without getting banned
- read the community's rules before your first post there. they are on the community's page, under about on the phone and down the right-hand side on a computer
- post as yourself and say it is your project
- spend more time commenting on other people's builds than posting your own
- post in one community at a time, not the same words in five on the same day
- every episode can go to r/buildingonunderway, underway's own community on reddit, where every founder posts theirs and one a day is welcome. in a community like r/buildinpublic, post once a week, not every episode
- reply to the comments, especially in the first few hours
- never ask anyone to upvote it
the format suits reddit better than most places. a numbered episode, the same day each week, with the bad weeks in it, is exactly what build-in-public communities reward. the founder who turns up every week gets recognised. the one who turns up once with a link does not.
the wider set of tools for posting a build, compared: build in public tools.
where is it?
on the episode page, in the posts on the share tab, under reddit. on the phone it is on the share tab too, with post to reddit under the words.
my older episodes have no reddit post.
posts written before this have none. press write them again and the whole set is written afresh, reddit included.
can underway post to reddit for me?
no. reddit approves every app by hand, and each community has its own rules. you press post yourself, which is also what keeps your account safe.
which community should i post in?
post to reddit opens in r/buildingonunderway, underway's own community on reddit, where every founder posts their episodes, daily if they like. to send yours somewhere else, type it in opens in, beside the button: a community, or u/yourname for your profile. r/buildinpublic wants one update a week, not every episode. others allow a project post once, or only in a weekly thread. read the rules first.
which plans have it?
every plan that writes the posts.
the posts, and everything else an episode comes with, are on the pricing table. see the plans.
this is part of underway's guide to building in public: how to build in public.

Founders’ episodes, written up.
Every public episode on underway has a page of its own: the video, then the same account in writing, checked against what the founder actually said.

YouTube thumbnail testing: 25 tries, video still flopped
My interview with Anthony, packaged around the US midterms, turned out to be one of my worst performing uploads despite trying twenty five different thumbnails. The last midterms-themed episode had passed 100,000 views, so I expected this one to land the same way, but none of the thumbnail tests fixed it. Anthony told me afterwards it was one of our best conversations, and we covered things like Elon Musk's political donations and the Citizens United ruling, so I don't think the content was the problem, I think my audience wants market talk rather than politics talk. I'm still not sure how to close that gap between a strong conversation and packaging that doesn't pull my regular viewers in.

Conversational AI demo: testing my co-host after 'AI slop'
I talk with Cedar, Underway's AI co-host, about feedback from my friend Alessandro, who tried the voice agent and said it felt like AI slop, giving generic, overly enthusiastic answers and talking over him. I ask the co-host to recall episode 40, where I built WhatsApp and Slack bots that nudge me to record, then test whether this newer version sounds more natural than before. I also ask if it has other voices or accents, but it currently only speaks in one voice with no accent switching.

Facebook ads top of funnel message vs what you sell
I ran paid ads for Underway and plenty of people signed up, but hardly any crossed the line because they put in a fake card. Recording this on the day it landed, because I don't want to pretend it's all going smoothly. Looking at it honestly, the ad that converts best doesn't relay what Underway actually is: the unique part is that it knows you and makes documenting easy, not that it clips videos together and puts a thumbnail on. I'm not giving up on it, but I'm back to the drawing board on the messaging.

Opus Clip and Riverside alternative: why I built my own
I explained what Underway is, the product I'm building with Rich that turns podcast conversations into highly produced videos and clips with data cards, charts and definitions, built as an alternative to Opus Clip and Riverside. I used Opus Clip for clips but found them generic, with no proper start, middle or end, and I'd been using Riverside for full episodes until I built my own engine instead. Underway now handles guest outreach, booking, recording in HD or 4K, editing, cutting horizontal and vertical clips and posting them, all front to back for other podcasters. I'm planning to post updates on Underway most days going forward.

Sending Meta ads to a buy page instead of a free funnel
I walked through Underway's Promote tab, which scans YouTube using your ICP and suggests a day in the life of a startup video I could film and rank for, plus a walkthrough it thinks will rank. I showed the marketing assets library, the ad answers tool that clips question answers into ads, and the reach numbers it pulls from the networks. I also messaged my Facebook ads guy yesterday to keep testing the free funnel but start sending traffic to a landing page to buy. The new website is up with the Steve Jobs video at the top, and the videos to film page is still quite hard to read, so I need to look at it again.
