Support for .xslx, .csv File Previews

When you get the big ol' bundle of round closing docs from your portfolio company's fundraising — or their demise — you'll sometimes get some spreadsheets thrown in among the PDFs as well. We now support previewing that file right on Signed, no download necessary:

Find Angel Investors Through MCP

Signed already has a directory of angel investors, and now your AI assistant can read it too.

Add mcp.signed.com/investors to Claude, ChatGPT, Cursor, or whatever you use, and ask it things like who writes $25K checks into climate companies? or which of these angels actually takes cold pitches? It’ll find them, tell you what they invest in and who they’ve backed, and point you to the right place to send your deck. You don’t need an account or a password. Just paste the link and ask.

Investors

Are you an angel investor and want to be included in the directory? Just sign up for a free account, easy peasy.

For existing investors, all of this still protects your portfolio information, of course; the public MCP server only searches over investors who have made their profiles public. If you want founders to find you, make your profile public in Settings and fill it in; it's free. The more full your profile, the higher you show up.

If you’d rather have your AI help with your own portfolio, you'll want our portfolio MCP at mcp.signed.com. That one needs you to sign in, for obvious reasons.

Sectors

We now have Sectors in Signed:

Sectors are from a set list: these are the sector breakouts we use on pages like the angel investor directory. Are sectors comprehensive? No. Are they an attempt at trying to make a general bucketing of companies that can help you compare and contrast between investments? Sure!

When we first see your company or pitch, we'll try to categorize it into a Sector based on the information we have at hand. You can always remove or override any Sector decisions.

We also have tags on Signed as well- those haven't changed. But now tags are much more oriented towards how you decide fit. You may tag something YC26, or To-Review, or any sort of categorization scheme you find helpful, and leave the sector classification up to us.

Pulley shutting down: find out how you're affected

This week, Pulley announced that they were shutting down. It's a real bummer; they were a lovely addition to the industry, and it was fun to see fresh blood in the space.

Beyond that, though, a natural reaction for an angel investor is to wonder what their personal exposure is to this, and how they might have to shift things around in the coming months. The first step is to use our new search facets on our MCP server for investments to see how many of your portfolio companies use Pulley for their cap table:

Pulley is winding down on December 8, 2026; in the meantime, a lot of the weight is shouldered by your founders, who will have to find a different path to take for their cap table management.

One thing you can be proactive on is to reach out to those companies (or mention it in your next meeting with them) and shoot them a link to Pulley's shutdown FAQ, if they haven't seen it already. When dealing with cap tables and legal structures, it doesn't hurt to be a little ahead-of-the-curve, since these types of moves can take some time to accomplish.

All of this is a nice benefit of ensuring you have clean data within your holdings on Signed; you'll be able to make these quick decisions via MCP or through our own website and be ready for whenever the next corporate event happens. In the meantime, if your companies are moving to another provider that's not listed within Signed, let us know; we'd be happy to add more custodians to Signed (and eventually integrate with them directly).

New UI: Company sidebars and investor updates

Quick splash of paint today! We now have a more refined sidebar that notes all of your favorite investment and startup metrics on the right sidebar on any company or pitch page. Just look for this new widget:

Our investor updates have gotten a similar treatment, too. Now when you forward an investor update to Signed, you'll see a more glanceable top box denoting the metrics that we imported and measured from that startup's email:

Now's a good time to remind you that these investor updates are great snapshots-in-time, too. Have a good JavaScript candidate in mind but can't remember which of your portfolio companies was looking for a JavaScript developer? Just search for "JavaScript" across your entire portfolio's history and see which startups might be a good landing spot for your them.

Tracking your startup's runway

Venture-backed startups live by the cash and die by the cash.

On occasion, you might run into a portfolio company that tries to downplay their current financial state. There's a big deal in the pipeline, or some cost savings coming, or a new feature's really going to kickstart revenue. That's all well and good, but money is the metric that cuts through that.

We already parse and import investor updates from your portfolio companies; you can also manually go in and add a new metric if you just got off a phone call, for example. Signed tracks a few different things: ARR, cash, burn, and now a runway. You'll see it in your company listing when you sign in, and also on the company sidebar.

We're now extracting those latest metrics from any update we have on a company and floating them up higher so you can see the import stuff right away. Signed also calculates a runway- a basic calculation of how much time the company has to live before the burn rate outweighs the cash on hand. This obviously can go up and down depending on costs, revenue, and financing rounds, and we'll keep adjusting the runway accordingly.

We'll also show an idea of where the company might be at today. In the image above, for example, you can see the green bar indicates the runway available when the investor update went out. But it's been a bit of time, so the today marker has moved closer to zero. The longer time passes without an update, the less accurate the runway calculation will be (and that's a great time for you to talk to your founder and get the low-down!)

Enjoy your burn!

New logo

MCP: File uploads

Our MCP server launched as a way to ask your portfolio questions; now you can run through the whole pitch pipeline, end-to-end.

Our previous release added pitch pipeline changes, where you can add new company pitches to your account. Now you can add (and remove) files from those pitches. So if you have a slide deck coming in from an email, or your agent is helping you power through your pitch triage, you can also add to the data room of those pitches.

One example we've been having fun with: using deckk to take a pitch deck's URL and convert it to PDF, so Signed's built-in PDF AI analysis tools can summarize and make it searchable.

As always, head to mcp.signed.com to set your agent up.

MCP: adding and updating deals

Quick little update for our MCP server: you can now create and update pitches.

So now you can just give your AI assistant a nudge, like: add the company I chatted with over lunch to my Signed pitch pipeline, or I'm going to pass on the deal from the company I met this afternoon.

We'll always be adding more fun capabilities to our MCP server, so keep an eye out. Or have your agent keep an eye out. Agents are doing everything anyway. Except this post. This post was written by a human. Totally.

Anyway, happy MCP'ing!

Reporting: your pitch pipeline

Part of Signed's biggest strength is having it take over your pitch pipeline: in other words, managing and tracking the companies you're talking to prior to deciding whether or not to invest. With our new Reporting dashboard for Pitches, you can dig into how you manage that pitch pipeline of companies.

For investors that have startup pitches submitted via Signed, you can now dig into the metrics around companies submitted to you: things like how responsive you are, how selective you are, and when you tend to pass on investing.

Users on the Investor plan now have access to the new Pitches dashboard. Can't improve a process without collecting the data first! Happy diligence-ing.
