Air cleaning technologies @ Intercept

[Jason Mazzella @jmazz_1]

Our team at Intercept is growing! I’m looking for amazing generalists to help our new fund accelerate our work on air cleaning technologies (ACTs), with the mission of making respiratory infections a thing of the past.

You’ll become an ACT product expert, go deep on what hampers real-world adoption, and help us execute on work to remove those barriers. Read more and apply below, and please send me the best people you’ve ever worked with!

We just announced Intercept, a new $500M philanthropic initiative that aims to make common respiratory infections a thing of the past. I’m very grateful for the chance to work on this with @nanransohoff and @incredutility!

I’ll focus on catalyzing the development and deployment of air cleaning technologies (like air filtration, antimicrobial light, and antimicrobial vapors) which we’ll need alongside broad-spectrum preventatives that defend us against respiratory infections.

We’re incredibly thankful to our anchor funders @stripe, @AnthropicAI, @TheFluLab, @FoundationOAI, and individuals from Jane Street, alongside our advisors and customer advisory board participants. Read more about our plans below and at https://t.co/BVVVWD0MB7.

[Nan Ransohoff @nanransohoff]

Today we're launching Intercept: a $500M philanthropic initiative to make respiratory infections, like the common cold and flu, a thing of the past.

We treat respiratory infections as a minor nuisance, but that’s really not the case. Most of us will spend 5% of our lives (!) sick from these viruses, they kill 1M people a year, cost $600B annually in productivity, and periodically threaten civilization through pandemics.

So, if they’re such a big problem, why haven’t we dealt with them yet? Last year we convened ~40 leading scientists, pharma R&D leaders, biotech investors, and regulatory experts to better understand that.

We heard two main reasons:
(1) First, it’s just technically very challenging: respiratory viruses represent hundreds of distinct, mutating strains across several families. Fortunately, recent breakthroughs make this newly possible.
(2) Second is a lack of funding: broad-spectrum solutions have historically been underfunded, in part because they’re not a great fit for most philanthropic or commercial funding (and while COVID generated a burst of activity around preventing and understanding respiratory infections through an influx of new funding, that hasn't been sustained).

We think that with enough focus and funding, this might be solvable. Intercept is a $500 million philanthropic initiative that will take advantage of new tools to catalyze the development and deployment of two types of products: broad-spectrum preventatives and air cleaning technologies.

This problem is undoubtedly difficult. But it’s more tractable now than it’s ever been. We think we should give it our best shot.

We’re enormously grateful to our anchor funders: @stripe, @AnthropicAI, @TheFluLab, @FoundationOAI and individuals from Jane Street.

And, I’m very excited to be building this with @incredutility and the rest of the team.

@adennurie_ @robjama hey @adennurie_ ! I'm Jason from the Stripe Atlas team - would love to speak with you about your experience and get feedback on how else we can help founders like you. DM or email me at [email protected] if you'd like to chat.

[Jason Mazzella @jmazz_1]

@NithurM @atlas That's correct! LLCs in Delaware have an annual fee due June 1 each year, and do not owe the franchise tax due in March.

[Jason Mazzella @jmazz_1]

Founders can now use stablecoins to pay Stripe Atlas incorporation fees!

[Stripe Atlas @atlas]

🆕 You can now pay for your Atlas incorporation and registered agent fees with USDC.

@aarondelasy Hi Aaron - I work on the Stripe Atlas team. I'm sorry to hear about this frustrating experience, it's certainly not what we intend for our founders. I'd love to speak with you to learn more and help find a path forward. DM me if you'd like to set up a chat!

[Jason Mazzella @jmazz_1]

💡Want to help Stripe Atlas improve our product?

I'm seeking founders who used Atlas in the last 2 years to share their experience registering for business in multiple US states, after incorporating in Delaware.

Stripe @atlas startups are growing faster than ever. The 2025 cohort has the highest median run rate yet, up 76% vs the 2024 cohort, with twice as many startups hitting $100K+ of revenue.

💡Want to help Stripe Atlas improve our product?

We’re looking for founders who used Atlas in 2025 to give us feedback on some new ideas we have to make the Atlas Dashboard more useful.

DM @jmazz_1 with your email address if you’re up for a quick chat.

[Jason Mazzella @jmazz_1]

🚀 Atlas companies can start charging customers faster than ever! Start accepting payments after incorporating, while you wait for the IRS to assign your tax ID.

Proud of the team that made this possible and excited for the Atlas startups that have one fewer obstacle to growth.

[Stripe Atlas @atlas]

Atlas startups can now accept payments *before* receiving their tax ID (EIN) from the IRS.

Ninety percent of founders are ready to fundraise, open a bank account, and charge customers within two business days of submitting their application. Learn more: https://t.co/pblqWOAGAy.

[Jason Mazzella @jmazz_1]

@bubble @atlas Great news for Atlas founders - more perks available to grow your business! (and for Bubble users, even more value when you incorporate on Atlas)

[Jason Mazzella @jmazz_1]

Great news for founders! Proud of the Stripe Atlas and Cooley teams that made this happen.

[Stripe Atlas @atlas]

Atlas startups now receive incorporation documents developed in collaboration with leading law firm @CooleyLLP. 🤝 https://t.co/GuNL1d9UdQ

[Jason Mazzella @jmazz_1]

@callmeed @jeff_weinstein @atlas @AnthropicAI @callmeed this offer is available in the Perks section of the Dashboard for all Atlas C-corps, including those who incorporated before we announced it!

[Jason Mazzella @jmazz_1]

@RVTikhonov hi @RVTikhonov - I work on Atlas, DM'ing you now to help figure out what happened and get you your credits.

[Pooja Parthasarathy @pparthasarathy0]

The obsession with users, craft, and metrics on the Stripe @Atlas team really is special.

1/ We care deeply about our users.

Our team reads every single message, tweet, or social media post that mentions Atlas. Not to mention every single NPS that isn’t a 10 (even the 9s) to understand exactly what we could be doing better.

2/ We're obsessed with details most people ignore.

Why should starting a company take weeks? Why not a day? Why not an hour? Why should a founder know or care about the concept of purchasing equity in their own company, or the mechanics of 83(b) elections? (Spoiler: They shouldn’t. @Atlas has now automated both these painful steps.)

3/ We measure everything.

And I mean *everything*. Not vanity metrics, but the stuff that tells us if we’re actually helping founders open a bank account, charge a customer, or fundraise faster.

@jeff_weinstein's chat with @lennysan goes into detail on everything Atlas and more. Go listen!

[Stripe Atlas @atlas]

You can now access banking through @brexHQ immediately after incorporation with Atlas. No waiting for the IRS to assign your EIN. 🏦 https://t.co/Bo0WwXFvca
