Pear VC
Pear VC@pearvc·
🚀 𝗣𝗲𝗮𝗿𝗫 𝗦𝟮𝟲 𝗮𝗽𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻𝘀 𝗮𝗿𝗲 𝗻𝗼𝘄 𝗼𝗽𝗲𝗻 AI has made it easier than ever to build. That also means it’s easier than ever to build something no one really needs. At the earliest stages, the real advantage isn’t how fast you ship — it’s how fast you learn to: 👥 Find real customer pain 🖥️ See workflows others miss 💡 Turn early insight into durable advantage That’s why PearX exists. It's our exclusive, small-batch program for pre-seed companies where founders get dedicated time with Pear VC partners — all former founders or operators. We work closely with teams on everything from customer discovery to fundraising to help them get on the path to success as fast as possible. If you’re interested in building with us, we’d love to meet you. 👉 𝗔𝗽𝗽𝗹𝘆 𝘁𝗼 𝗣𝗲𝗮𝗿𝗫 𝗦𝟮𝟲 𝘁𝗼𝗱𝗮𝘆: 𝗵𝘁𝘁𝗽𝘀://𝗽𝗲𝗮𝗿.𝘃𝗰/𝗽𝗲𝗮𝗿𝘅/

We just opened applications for PearX S26 (see comments for link). At Pear, we do pre-seed differently.  Our partnership with PearX founders goes beyond the ten weeks of PearX.  You become our portfolio company and we work tirelessly to get you through Series A and beyond!

Known is finally live on the App Store. San Francisco feels a little different this morning. For the past few months, we’ve been building a new kind of dating platform for the post-swipe era.  Known is intentional, designed to get people on real dates. Love is coming.

Jumping into the dialogue here. I'd love to see Boston become a thriving place for tech companies 🏙️. Context 🧩: South Florida born and raised and hate all Boston sports teams → MIT ’17 → SF early-stage startup → founded a YC-backed company → back in Boston as a Partner at @pearvc. Still hate Boston sports teams but love the city of Boston and want to see it succeed. Boston has insane talent thanks to our university ecosystem. The problem is this talent gets drained every year because the majority of cutting edge companies that people want to work for are in SF and NY. If Boston wants to matter in tech again, three things need to happen💡: 1. Fix how MA enforces non-competes & non-solicits (per @parker_mckee) 2. Convince a few fast-growing SF/NY startups to move HQs here, would require significant incentives 3. Restart the early-stage flywheel by building a dominant Accelerator in Boston This post is mostly about #3. @epaley @bhalligan — know anyone that can help with #1 and #2? Why an accelerator matters: Accelerators fund a lot of startups. Look at SF. YC is funding 600+ per year now. Pear and Speedrun are also funding many companies. Some startups succeed, most fail. The successful ones grow quickly and hire a lot of people. Some of those people leave to start their own startups, this is how we get startup mafias. Companies stay put if there's enough talent density to hire from. Venture capital enters the ecosystem and the flywheel turns. It’s a self fulfilling prophecy. 🔄 With MIT & Harvard, Boston will always have the talent needed to restart the flywheel. We just need to put a system in place to grease the wheels. Here’s what it would take to build a dominant accelerator in Boston (from a former YC founder who now has a front row seat to PearX) 👇 1) Top Tier Group Partners 👑 Former founders with real operating experience, strong Boston ties, and deep credibility with MIT/Harvard talent. A few generalists with experts across different focus areas (AI, B2B SaaS, Robotics, Deep Tech, Defense/Manufacturing, Climate, Biotech, Healthcare, Fintech, Consumer, etc) There needs to be at least a few big names here for this accelerator to be relevant. You could seed it with visiting partners that are current founders and want to see Boston succeed: @patrickc, @mntruell, @luanalopeslara, @MikeyShulman, @jrkelly, @willahmed, @jerallaire, @steve_fredette. What other halo founders with Boston ties might be interested? 2) Competitive (or better) economics 🤑 YC is effectively ~$500k for ~10%. Pear, NEO & SPC have even better terms. This accelerator must compete with Silicon Valley pricing and move fast. One meeting decisions. High-slope people > polished decks. 3) A real physical home for founders 🏠 Big office space where founders work shoulder-to-shoulder each batch. Think: The Engine / Pillar / Link / VenX — but even larger — plus partnerships for deep tech & biotech space. This matters more than people think. Proximity compounds. 4) Everything else that makes the flywheel spin -Strong ops + programming team to run the Accelerator -Engaged angel community -Early breakout wins that stay rooted in Boston -Support from MIT & Harvard (MIT has some work to do, their startup ecosystem is too decentralized with many competing interests) -Convince other east coast talent (Ivy League, CMU, Waterloo, Georgia Tech, Duke, etc) to join the party -A government that wants the tech ecosystem to thrive -Cheaper housing -Making Boston a better place to live for people in their 20s Boston doesn’t have a talent problem. It’s a system problem. If we make it stupid-easy for great people to start companies here — and give them reasons to stay — the rest follows. If we don’t, nothing will change. I would love to see Boston become a thriving tech ecosystem again. Until then, our talent will continue to get drained.

I’m starting to worry about Massachusetts 1. Biotech is way off from a few years ago 2. Only 1 of the top 50 ai companies are in MA 3. The Fed research funding cuts hitting MIT, Harvard, Whoi are brutal. 4. The millionaires tax is working in the short run, but I know a lot of wealthy folks preparing for a FL move. 5. A glut of empty condos 6. It’s not “cool” for young folks 7. It’s expensive as sh-t. I honestly don’t think the MA/Boston govt can do that much about it as they are kind of macro issues. I give them big credit for working on building more housing and fixing the T, which will help. I’m trying to help w HubSpot, partnering w WHOI, teaching at MIT. I’d like to help more. Specifically I’d like to encourage and help more ai and climate companies in the state. I think ai and climate should be our dual growth engines.

Today, we are launching the first publicly available AI Scientist, via the FutureHouse Platform. Our AI Scientist agents can perform a wide variety of scientific tasks better than humans. By chaining them together, we've already started to discover new biology really fast. With the platform, we are bringing these capabilities to the wider community. Watch our long-form video, in the comments below, to learn more about how the platform works and how you can use it to make new discoveries, and go to our website or see the comments below to access the platform. We are releasing three superhuman AI Scientist agents today, each with their own specialization: A general-purpose agent (Crow); An agent to automate literature reviews (Falcon); and An agent to answer the question “Has anyone done X before” (Owl). We are also releasing an experimental agent, Phoenix, that has access to a wide variety of tools for planning experiments in chemistry. More on that below. The three literature search agents (Crow, Falcon, and Owl) have benchmarked superhuman performance. They also have access to a large corpus of full scientific texts, which means that you can ask them more detailed questions about experimental protocols and study limitations that general-purpose web search agents, which usually only have access to abstracts, might miss. Our agents also use a variety of factors to distinguish source quality, so that they don’t end up relying on low-quality papers or pop-science sources. Finally, and critically, we have an API, which is intended to allow researchers to integrate our agents into their workflows. Phoenix is an experimental project we put together recently just to demonstrate what can happen if you give the agents access to lots of scientific tools. It is not better than humans at planning experiments yet, and it makes a lot more mistakes than Crow, Falcon, or Owl. We want to see all the ways you can break it! The agents we are releasing today cannot yet do all (or even most!) aspects of scientific research autonomously. However, as we show in the video, you can already use them to generate and evaluate new hypotheses and plan new experiments way faster than before. Internally, we also have dedicated agents for data analysis, hypothesis generation, protein engineering, and more, and we plan to launch these on the platform in the coming months as well. Within a year or two, it is easy to imagine that the vast majority of desk work that scientists do today will be accelerated with the help of AI agents like the ones we are releasing today. The platform is currently free-to-use. Over time, depending on how people use it, we may implement pricing plans. If you want higher rate limits, especially for research projects, get in touch. @m_skarlinski, @andrewwhite01, @_tnadolski, Remo Storni, @semajazarb, @ludomitch, @MichaelaThinks, as well as @jasonjoyride and his team for making such fantastic videos of us!

New from FutureHouse. I've been playing around with the new platform for the past week or so, and I've been blown away by what's possible. Throw away your intuitions -- just try things!
