Josh Blumberg

I'm looking for my next gig. If you're hiring backend engineers in NYC, let's chat. What I'm good at: - Learning complex/regulated domains deeply - Working with agency and taste to ship quickly - Unwaveringly considering customer needs What I'm bad at: - Leetcode - Bureaucracy

@LM_Braswell Know anywhere like this but in NYC?

Crazy hiring stats for a Series A company I work with: * 1/3 of the team is former founders * The quality of the last 10 hires (#25-35) is at least on par with the first 10 hires * No team churn since start of company / extremely strong culture Looking for a Head of Talent to continue to scale! Message me if you'd like to learn more.

@vral Hey, got any spare invites? Just saw my request was denied

Come hang with the @ThriveHoldings @tryramp @pacecom teams next week in NYC

@zebriez Makers academy, a coding bootcamp. Generally, she helped students navigate rapid change. Literally, she taught meditation, yoga, introspection and feedback workshops.

@Bblurg where? what did they do?

what's the weirdest job title you've heard of someone having?

@bcherny I often iterate on a plan 10+ times before starting work on it. First few iterations change a lot, later iterations change a little. Can we have an option to view a plan diff rather than the whole new plan to make this easier? I can imagine using both

@bcherny @melvynx @claudeai Your patience with keyboard warriors is admirable

@melvynx @claudeai This isn’t hiding anything, this is a bug. Fix going out today.

Oh @claudeai @bcherny etc. stop hiding things from us! It's insane; you hide the file, then the tools, and the chat starts to be obfuscated. It's really sad for developers You should make a feature flag for this kind of stuff

@mehul > 50% of our "minimum lovable roadmap" hasn't even shipped yet! Thoughts on making this public?

"What can 60 people build in a year? 5K+ robots shipped 100M+ sqft cleaned 270K+ hours saved 50+ new releases 1k+ heartwarming customer reviews (thank you!) 2025 was huge, but 50% of our "minimum lovable roadmap" hasn't even shipped yet! Buckle up.🤖✨

@MattHdeJonge @traestephens @StevenLevy @MattHdeJonge hey, are you hiring software engineers? > I’ve never seen such a categorical result in my career This data point is impressive, never mind the anecdotes. Great to see openness to peer review as well. Would love to meet. More on me: linkedin.com/in/josh-blumbe…

@traestephens @StevenLevy 👋🏻

Could not be more excited for the launch of Fortell - the best hardware demo I've seen in all of my years at Founders Fund.

@jonas Doesn’t sainsburys have an api? I thought that’s what cherrypick use

Whichever UK grocery delivery service first launches an MCP server or other API wins my business

holy shit

Which is the point at which we’ll wish we turned back? I’m currently very pro AI, but this is worrying.

@taimurabdaal What do when both sides are embarrassing but the new middle is also embarrassing

Why are the people claiming to “fearlessly pursue the truth” always the ones with the dumbest, most naively tribalistic takes? University of Austin Texas, founded by Joe Lonsdale and Bari Weiss, and bankrolled by Bill Ackman and Elon, is an SNL-skit-level parody of this phenomenon: UATX was founded in 2021, their motto is “dare to think” and their tagline is “dedicated to the fearless pursuit of truth”. Nice ideas for sure, even if the wording is a bit tacky. When setting up, they got big names on board as advisors and fellows: Larry Summers (former Harvard president), Robert Zimmer (former UChicago president), Steven Pinker, and others. But right out of the gate, insiders started getting spooked: – Robert Zimmer stepped down in 2021, saying that UATX made statements that "diverged very significantly from my own views" – Steven Pinker also stepped down in 2021, citing that UATX "confused freedom of speech with the political right" – Heather Heying, a board member, resigned in 2022 stating that UATX "does not represent my scientific and pedagogical values" But look — UATX is in the arena trying something hard, and sure they were rough around the edges to start off, but perhaps they just needed a couple of years to mature? Unfortunately, that doesn't seem to have happened. Just this year: – Larry Summers resigned from the board, saying "I am not comfortable with the course that UATX has set nor the messages it promulgates" – They cut off The Mill Institute, a previously UATX-beloved affiliate, because of a LinkedIn post in which they said "We can have criticisms of DEI without wanting to tear down the whole concept of diversity and inclusion" (full story here: quillette.com/2025/05/16/is-…) – They seemed to have leaned even more into the culture war — just look at quoted post and the rest of their X feed UATX started as backlash against woke stuff at universities, which I'm very sympathetic to, as were their initial backers. But it looks like their pursuit of truth stops where sincere and civilised enquiry begins. Some reflections from me: 1. It's quite sad but also a bit funny that "caring about truth" has been co-opted by a very specific crowd who've done such a bad job at it that it's now become an orange/red flag if someone overtly signals "truth-seeking" 2. It would be great to see more niche universities get started and flourish, but attempts like UATX probably make it much harder for new entrants to be taken seriously. Like the Theranos effect for blood-testing startups 3. Not exactly an original point but: it's worrying that a handful of reactionary billionaire buddies (Joe Lonsdale, Elon, Bill Ackman, and others) can mobilise billions of $ and wield outsized political influence to peddle their ideologies. This is an old phenomenon, but the proliferation of power laws makes it much worse. I like the "marketplace of ideas" concept, but right now I think we're closer to a "war of all against all" than any kind of "free market"

@raunakdoesdev Hiring in NYC?

Big milestone for Reducto: we’ve raised a $75M Series B led by a16z, bringing our total funding to $108M. Since our launch, we’ve been obsessed with pushing the limits of what’s possible when AI meets the real-world messiness of documents. We’ve now processed 1B+ pages, nearly 6x the pages since our Series A less than 6 months ago. We’re doubling down on model research, developer tooling, and the reliability that production AI demands. We'll be announcing a series of product improvements that will extend our capabilities even further, helping our customers get even closer to perfect accuracy across their most challenging docs. A big thank you to everyone who helped get us here. But we're just getting started - if you're interested in what we're doing, we’re hiring across all functions! reducto.ai/careers

Was thinking about early warning signs things are going sideways in startups today. “Code smells” aren’t bugs per se, they’re early warnings and startups have them too. Some that make me nervous 1/

I call this the “Zillow Effect” Seamless online transactions increases demand while supply stays the same. Applies to housing, job applications, college applications, used items, concert tickets, dating, hot vacation spots, and more
