@Jaro_rogue Check out @CarbonArcAI. We offer an API and MCP server so anyone can access datasets including transactions, foot traffic, maritime data, and more. Put the data directly into Excel, Claude, anywhere.

Brett nailed it: AI companies are enabling everyone to ship amazing UIs, but institutional accuracy has been the blocker. That’s precisely the problem Carbon Arc and our MCP server solve: structured, model-ready data delivered directly into Claude, Excel, etc.

Someone is a cheap Capital IQ API equivalent away from becoming a multi-millionaire. Everyone will be able to make their own dashboards in a day. Only thing that keeps koyfin and tikr in business is their access to enterprise Capital IQ where they can spread cost across users.

The real threat to your B2B app isn't AI agents or fewer seats. And it certainly isn't they will vibe code you awawy. It's that your customers are quietly doing more and more inside Claude instead. The storm circle is closing. Every month Claude can take over a little more of what your app does.

@AlecEllin @italic Similar businesses, but the data shows both companies have been moving in opposite directions!

@yenkel Agree, there are issues that come with working with customers to use MCP servers. But the magic to debug and auth have been great in getting our product running

@onequince just announced a $10bn raise. With @CarbonArcAI MCP in Excel, I pulled transaction and web traffic data in a single prompt. Anyone can sign up for Carbon Arc and access data on thousands of companies with a simple ask!
John Cusick@jcusick5

@packyM Using @CarbonArcAI, I pulled transaction and web traffic data for Quince. You can see the tremendous growth since 2023, peaking at over 1,400% growth in credit card spend over the holiday season!

We wrote the first check into Quince and never shared our thesis publicly At the time, D2C was radioactive and 'affordable luxury' sounded like an oxymoron. Today they raised at $10B. We couldn't be more excited. Here's why we believed — and why we think it's still early! 8vc.com/resources/quin…

Frontier models are exceptionally efficient, intelligent, and useful. For agents, context is now the bottleneck. Enter the context layer, which bridges the gap from an enterprise's messy data to actionable context, packaged for agents. We're seeing three distinct verticals emerge in the context layer space: - Data gravity platforms - Existing AI data analysts - New, dedicated context layer companies Read the full piece by @JasonSCui and @JenniferHli: a16z.news/p/your-data-ag…

Claude can now directly access Financial Datasets through MCP. You can ask questions in natural language and access income statements, balance sheets, cash flow statements, and more for 17,000 companies over the past 30 years. Too bad Bloomberg isn’t publicly listed.

𝗧𝗼𝗱𝗮𝘆 𝘄𝗲’𝗿𝗲 𝗹𝗮𝘂𝗻𝗰𝗵𝗶𝗻𝗴 𝗟𝗲𝗻𝘀𝗲𝘀. For the past five years, we’ve been building Carbon Arc — the infrastructure that makes real-world transaction data accessible to institutions around the world. Today, on our anniversary, we’re expanding that foundation with a new product. Lenses is an AI-powered research interface on top of our full external data catalog — consumer spend, foot traffic, app downloads, pharmacy claims, payroll, logistics, and more. Pick a lens that fits how you work: 𝗜𝗻𝘃𝗲𝘀𝘁𝗶𝗻𝗴? Build conviction before the Street catches up. 𝗠𝗮𝗿𝗸𝗲𝘁𝗶𝗻𝗴? Track competitive share as it shifts. 𝗖𝗼𝗻𝘀𝘂𝗹𝘁𝗶𝗻𝗴? Scope a vertical in minutes, not weeks. No pipelines to build. No queries to write. Just ask a question and get structured answers — tables, charts, narrative context, and follow-up depth — all in one conversation. See it in action in the video below ↓ 𝗙𝗶𝘃𝗲 𝘆𝗲𝗮𝗿𝘀 𝗼𝗳 𝗶𝗻𝗳𝗿𝗮𝘀𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲. 𝗢𝗻𝗲 𝗶𝗻𝘁𝗲𝗿𝗳𝗮𝗰𝗲. To celebrate the launch, use code LAUNCH30 for 30 days free. 𝗗𝗼𝗻’𝘁 𝗯𝗲𝘁 𝗼𝗻 𝗼𝘂𝘁𝗰𝗼𝗺𝗲𝘀. 𝗖𝗿𝗲𝗮𝘁𝗲 𝘁𝗵𝗲𝗺.

This @perplexity_ai usecase blew my mind. I've always wanted a tool that tracks all S&P500 earnings and key things said by executives in their earnings calls. I simply do not have the time and bandwidth to read all 500. Prompt: I want an interactive dashboard that tracks every single earnings report in the transcripts of the S&P 500 companies every quarter. Note common themes that executives are talking about. Keywords and trends that could help me potentially make money and identify larger trends. As a momentum trader. S&P 500 Earnings Intelligence Dashboard is live and fully updated with 484 company transcripts covering the latest earnings season. What's inside: 5 KPIs at a glance — total companies, themes tracked, momentum signals, average sentiment, and sector coverage Theme frequency chart : aggregated by GICS sector, so you can see which sectors are driving each narrative (AI CapEx, margin expansion, regulatory risk, etc.) Sector sentiment ranked as horizontal bars — Utilities leading at 0.79, Consumer Staples trailing at 0.66 12 momentum signals — 8 bullish, 3 caution, 1 energy transition — with the tickers behind each signal Searchable executive quotes with sector filters and pagination across all 484 companies Full sector breakdown showing every company's sentiment, themes, and key quotes Recurring refresh: A quarterly refresh is scheduled for May 15, Aug 15, Nov 15, and Feb 15 at 9am EST (cron a07f9c7c). Each run will pull fresh transcripts for all S&P 500 constituents, reprocess through NLP, and redeploy the dashboard automatically. @jeffgrimes9 @dnlkwk @alexhong @AravSrinivas Computer IS INSANE. Can't wait to see what else I can build for myself.

Brett Caughran@FundamentEdge

This is super interesting as well I've been experimenting with AI driven data dashboards to more systematically track company KPIs. So much of the public-equity research process is about developing better revenue forecasts (which then flow down to EPS at various incremental levels). Thus, so much of the investment research motion is about tracking data that informs more accurate revenue forecasts. This is the foundation of the alternative data industry. But there are many helpful data sets sitting in the open. As chatbots have grown arms (Claude), I have been impressed by the ability of these tools to go grab this data. x.com/FundamentEdge/… To me, this is the other missing piece that sits alongside Excel fluency. The ability to ingest an Excel model (eventually build it, but not today), identify key drivers (from open and proprietary data), distill that data back into forecasts, and flag back custom alerts (business momentum inflections, likely revisions to revenue forecasts, thesis validation/invalidation, etc). Now we are talking!! This is orders of magnitude more helpful than a finance chatbot wrapper. I do wonder if these tools are progressing at such a pace that most finance professionals don't even need to learn coding agents. For example, Perplexity Computer one-shotted something that, for sure wasn't perfect, but exhibits material progress in the capability of the harness infrastructure to build simple, powerful user interfaces. Institutional grade accuracy remains a critical & still not fully solved issue (does this improve as firms like CarbonArc roll out MCPs??), but it is exciting to see the engineering capabilities improve so materially, in such a short period of time.

The barriers to using 3rd party data in your workflow are coming down fast! @CarbonArcAI allows you to sign-up, purchase data, and analyze it in your Excel sheet in as little as 30 minutes vs. the months long compliance and data engineering process it traditional takes.
Carbon Arc@CarbonArcAI

If you have the Carbon Arc MCP Server connected in @claudeai, you have it in Excel! Seamlessly ask for and bring data from Carbon Arc right into your spreadsheet. Demo below 👇

$ANF opening down 5%, with their YoY growth coming in on the low end and muted Q1 guidance. Hard to argue with the data, as Carbon Arc’s MCP flagged the weakness across card spend, transactions, and foot traffic.
John Cusick@jcusick5

Ahead of $ANF earnings tomorrow, I used @CarbonArcAI's MCP to quickly analyze a variety of datasets and compare YoY changes. Management guided for at least 6% growth in the quarter, but many data sets point to a slower holiday season.

$ANF reports today. I think this could be the next consumer brand disappointing badly for 2026. Maybe its already priced in since its down -23% now BUT wall street estimates still expect 5% growth yoy next Q while observed credit card sales in Jan and Feb indicates -10% yoy…
