Excited to announce our new fund today! We are proud to continue the work of backing founders who show us what the future can be. ✨

I'm honored to share that @BainCapVC is leading @solcoatech's $75M seed financing. One year ago they were proving chemistry on a demo line, they've since scaled to a full production facility in Alameda, and today announce Solcoa One, their 500-tonne rare earth metallization plant in Nevada.

Make money. Have fun. Live with integrity. Everything else can change. Fund XI. $1.6B total capital for those who know that it will.

In 1987, when Bain Capital was ≈3 years old, the early partners came up with the briefest possible mantra for running the firm: make money, have fun, live with integrity. Excited that BCV has another $1.6B to do that. @kevinzhang , @ChristinaPhili5 , and I wrote a bit about those principles and the role that capital should play in a technological revolution: baincapitalventures.com/insi…

Today we're announcing our $100M Series C at a $1B valuation, led by @ICONIQCapital. It's our third round in 14 months and brings our total funding to over $200m The round came together in less than 48 hours. We weren't planning to raise. Then new ARR doubled last quarter and we crossed 600+ customers including public companies and enterprises with $2B in revenue. Rillet AI agent usage is growing 70% each month and CFOs are replacing Oracle Fusion, SAP and Workday to run their companies on Rillet. We also announced our alliance with EY and officially partnered with more than half of the top 20 CPA firms. @RilletHQ is creating an entirely new category of finance infrastructure. With Rillet, the ERP becomes the harness for the modern finance organization, where people and agents share the same financial data, apply the same accounting policies and controls, and work from a single, continuously updated view of the business. Agents perform increasingly complex financial work, while finance teams retain visibility, approval authority and a complete audit trail. Thank you to our customers for believing in the mission and building the future of finance with us. We could not do this without you. Thank you to the Rillet team. As I say often, building Rillet is our own version of sending rockets to Mars. It is incredibly difficult. You make it look easy. Finally, thank you to our investors. To ICONIQ for leading the round and to our existing and new investors for building with us. @sequoia , @a16z, Sequoia Global Equities, @BainCapVC, @oakhcft, @BatteryVentures, @FirstMarkCap, @scalevp, and @creandum. Back to work :)

When we started researching @Rillet, we reached out across the Bain Capital portfolio to make CFO intros. Turns out, many didn’t need one. They were already customers. That kind of pull is notable in ERP, a category built around systems that are notoriously hard to rip out. Rillet is building accounting superintelligence: a real-time ledger with deep context and agents that tackle increasingly complex financial work. We’re excited to participate in Rillet’s $100M Series C as @nicckopp and team take on some of the most entrenched players in enterprise software! cc @Abby__Meyers Josh Xu @BainCapVC fortune.com/2026/08/18/rille…

Exclusive: AI chip startup Etched, founded by Harvard dropouts, has its own in-office data center and has signed quant-trading firm Jane Street as its first customer on.wsj.com/4icT4hF

We are excited to partner with @Etched as they bring cutting edge frontier inference clusters to market. Congrats @robertwachen @UbertiGavin @czhu1729! Cc @EnriqueSalem @Abby__Meyers Alex Roose @BainCapVC

Five months ago, Simile came out of stealth with a $100M Series A. Today, the company is announcing more than $200M in funding at a $2B valuation. It’s a reflection of their relentless execution, progress, and vision for a world with more humanity in it, and this is why @aaref , @rkhkimx and the @BainCapVC are doubling down.

Whop Co-Founder & CEO @cultured’s advice to young people: - Experiment as much as possible - Don't feel like you're wasting time "The only real risk is not doing anything."

Software automated bits. ATOMS will automate atoms. We are thrilled to back @travisk and his team as they launch a new platform for physical AI. ATOMS is fundamentally rethinking the tech stack to drive industrial progress across autonomous transport and autonomous robotics. Very few founders can conceive of a vision this audacious, let alone execute it. @travisk is one of them. @BainCapital @BainCapVC @Abby__Meyers @EnriqueSalem @ajay_bcv

This was so much fun! Ron, Ryan and I were fortunate to work with @ryanjdaniels in the early days before he knew what Crosby would become. The son of 2 law professors, Ryan was born to start this company. He was early to the idea that AI would transform services, and made a bet about commercial contracts as the place to start that turned out to be correct. Crosby offers a radically better value prop of speed and quality to their customers, which resonated instantly with the fastest growing AI companies. They are pioneering the playbook of the neofirm, and they have built an incredible team in NY!

We at @BainCapVC are thrilled to announce we led the $10M seed of @joinadaptive and are doubling down in their $50M Series A. Adaptive is tackling one of the largest and fastest growing sectors in healthcare: the $140 billion home health market. As an AI-native service end to end, they have built an important flywheel of lower back office costs and better clinician experience that leads to greater patient acceptance, higher density and better outcomes. @AlexRWendland and @ryanatolsma have built an exceptional team, and we couldn't be more excited to see them build healthcare that America deserves.

When Chris Turlica and Hugo Dozois-Caouette started @maintainx, they were solving a problem that Silicon Valley wasn’t paying attention to: 80% of the global workforce wasn’t working at a desk, yet only 1% of software spend went toward tools for them. MaintainX built world class software for the factory floor. Today, this early insight becomes mainstream with Autodesk's proposed acquisition of MaintainX for $3.6B. We are proud to have led MaintainX's Series C in 2023 and co-led the Series D in 2025 alongside our friends at Bessemer. The tenacity, vision, and consistency that "Killer Teddy Bear" Chris Turlica and team bring to work every day are unparalleled. It has been a joy to work with them. Congratulations to the entire MaintainX team on this well-deserved milestone. baincapitalventures.com/insi… cc @BainCapVC @Abby__Meyers

In under 18 months, @WeAreLegora have scaled from $1M to $100M in ARR, a milestone that almost no enterprise software companies reach so quickly. Legal AI is now entering the 1 to 10 phase, where agents, automation, and entirely new workflows will redefine what’s possible.

Memo is a robot that uses AI to perform household tasks effectively. Today @sundayrobotics announced its Series B, and we’re proud to be investors. Training robots for the home is hard — the environment is messy, dynamic, and full of edge cases. So Sunday is training robots directly on real households. Founders @tonyzzhao and @chichengcc built a glove-based system that lets hundreds of contributors record everyday tasks in their own homes, creating high-fidelity demonstrations that feed directly into robot learning. Home robotics will be defined by the companies that learn fastest from real homes. Sunday is building that loop. More here: baincapitalventures.com/insi… @aaref @amandamhuang

We invested in @WeAreLegora for a simple reason: users love the product. In our diligence, lawyers consistently described Legora as the most production-ready AI platform for legal work. Better handling of large documents. Cleaner formatting. End-to-end execution on complex tasks like multi-version contract review. The difference shows up in the last mile and in legal, that’s what matters. Legora combines strong product instinct (multi-model from day one, built inside native workflows) with real shipping velocity. Clear product judgment. Intensity around execution. @MaxJunestrand & team — excited to be in your corner as you build the defining legal AI platform. baincapitalventures.com/insi… @wearelegora @Abby__Meyers @josh_xu16 @BainCapVC

Pylon began with a simple belief: B2B support had outgrown the tools built to manage it. Teams weren’t working in silos anymore. They were collaborating in real time, across functions, around the same customer. The old systems weren’t broken. They were outdated. So Pylon built a new system of record for the way companies actually operate. Now 1,500+ customers rely on it. @usepylon @marty_kausas @merritthummer @Abby__Meyers

Before @usePylon had customers, it had an air mattress. @marty_kausas had left Airbnb, heard the market was “crowded,” and was told to get a normal job. The problem wouldn’t let go. B2B support isn’t ticketing — it’s sales, success, and finance working in the same thread. Legacy tools weren’t built for that. Today: 1,500+ customers. $51M raised. Still happy. Still grinding. cc: @merritthummer @Abby__Meyers
