The Portfolio Management Stack: What Top Accelerators Actually Use

Running an accelerator is not just about selecting great founders and delivering a killer demo day. Between batches, the real work is portfolio management - tracking KPIs across dozens of companies, coordinating mentors, managing follow-on investments, and reporting to LPs.

We spoke to program managers at 12 accelerators across the US, Europe, and Asia to find out what tools they actually use day-to-day. Not what is on their website - what is open on their screens.

The core stack

Most accelerators converge on a surprisingly similar set of tools. The differences come down to portfolio size, stage focus, and how hands-on they are post-program.

1. Portfolio tracking and reporting

This is the single most important tool decision an accelerator makes. You need somewhere to collect founder updates, track key metrics, and generate LP reports.

Recommended Tool

Visible

Visible is the clear favorite among the accelerators we spoke with. Eight out of twelve use it as their primary portfolio tracking tool. Founders submit updates through a simple form, and the accelerator gets a unified dashboard with revenue, burn rate, headcount, and fundraising status across the entire portfolio.

"We switched from spreadsheets to Visible two years ago and it cut our LP reporting time from three days to three hours." - Program Director, Series A-focused accelerator

For accelerators running 50+ portfolio companies, the alternative is building custom dashboards on Airtable - which three of our respondents do.

Recommended Tool

Airtable

Airtable gives you more flexibility but requires significant setup. One accelerator shared a base with 14 linked tables tracking everything from founder contact info to board meeting notes to follow-on round details.

2. Cap table and equity management

Every accelerator takes equity. Managing that equity across dozens of companies - with SAFEs converting at different caps, pro-rata rights, and follow-on investments - gets complicated fast.

Recommended Tool

Carta

Carta is nearly universal. Eleven of twelve accelerators use it, and most require their portfolio companies to use it as well. The accelerator gets a fund-level view of all positions, and founders get clean cap table management from day one.

"We make Carta onboarding part of our first week. If founders do not set up their cap table properly early, it creates a nightmare at Series A."

3. Communication and coordination

Running a batch means coordinating mentors, scheduling office hours, sharing resources, and keeping 10-20 founding teams aligned on a tight timeline.

Recommended Tool

Slack

Every single accelerator we spoke with uses Slack as their primary communication tool. The typical setup includes:

• A workspace per batch with channels for announcements, asks, wins, and social
• Dedicated channels per company for mentor-founder discussions
• An alumni workspace that persists across batches
• Integration channels pulling in updates from Visible, Carta, and calendar tools

Recommended Tool

Notion

Notion serves as the knowledge base and program playbook. Accelerators use it to share:

• Curriculum and session recordings
• Founder resource libraries (legal templates, pitch deck examples, investor lists)
• Internal ops documentation
• Mentor directories and matching notes

4. Operations and scheduling

Accelerator programs are logistics-heavy. Demo day prep, mentor matching, investor meetings, and founder check-ins all need to be coordinated across dozens of calendars.

Recommended Tool

Calendly

Calendly handles the scheduling burden. Most accelerators create booking pages for mentor office hours, partner check-ins, and investor speed-dating sessions. The round-robin feature is particularly useful for distributing mentor meetings across the team.

Recommended Tool

Linear

For the accelerator team itself, Linear is increasingly popular for managing internal operations - tracking tasks like "review Company X pitch deck," "intro Founder Y to Investor Z," and "follow up on portfolio company quarterly updates."

5. Finance and banking

Accelerators manage their own fund finances alongside advising portfolio companies on theirs.

Recommended Tool

Mercury

Mercury is the default banking choice for both accelerators and their portfolio companies. Several accelerators mentioned that having everyone on the same bank simplifies wire transfers for investment and makes it easier to advise founders on cash management.

Recommended Tool

Stripe

For accelerators that charge for events, run paid programs, or process demo day ticket sales, Stripe handles payments. One accelerator processes over $200K annually through Stripe for their growth-stage program fees.

6. Data and analytics

Understanding what is working in your program requires data - on founder engagement, mentor effectiveness, and portfolio outcomes.

Recommended Tool

Mixpanel

A few accelerators track engagement with their own platforms and resources using Mixpanel, though this is more common at larger programs with custom-built founder portals.

For most, the analytics stack is simpler: Visible for portfolio metrics and a combination of Notion databases and Airtable for program-level data.

7. Legal

The legal stack matters most during batch intake (investment documents) and when portfolio companies raise follow-on rounds.

Recommended Tool

Clerky

Clerky handles incorporation and standard startup legal documents. Several accelerators require portfolio companies to incorporate through Clerky to ensure clean legal structures from the start.

8. Marketing and founder storytelling

Accelerators increasingly help portfolio companies with go-to-market - not just product-market fit. One area that has taken off recently is turning founders into visible thought leaders through content.

Recommended Tool

DocuSpeaker

DocuSpeaker is a newer tool that several accelerators have started recommending to their cohorts. It converts written content - blog posts, pitch decks, investor updates - into natural-sounding audio and video, letting founders repurpose a single piece of writing across podcasts, social media, and their website without booking studio time.

"We added DocuSpeaker to our marketing toolkit last batch. Founders were creating audio versions of their launch posts and investor updates in minutes instead of spending a day recording." - Batch Lead, pre-seed accelerator

For accelerators that run demo days and produce content around their program, DocuSpeaker also helps turn recap posts and founder spotlights into multimedia assets that reach a wider audience.

What surprised us

Three patterns stood out from our conversations:

Fewer tools than expected. Most accelerators use 6-8 core tools, not 20. The ones with the most complex stacks were often the least satisfied - too many tools means too many places where data lives.

Spreadsheets persist. Even with Visible and Airtable in place, every accelerator still has at least one critical spreadsheet. Usually it is the master deal flow tracker or the LP commitment schedule.

The alumni network is underserved. Nearly every program manager mentioned that their weakest tooling is around alumni engagement. Slack workspaces grow stale, and there is no great solution for keeping 500+ alumni founders connected and active.

Building your stack

If you are setting up or upgrading your accelerator's portfolio management tools, here is the priority order we would recommend:

1. Start with Visible for portfolio tracking and LP reporting - it is purpose-built for this
2. Require Carta from day one - cap table hygiene compounds over time
3. Set up Slack properly with a clear channel structure and naming convention
4. Build your playbook in Notion - make it the single source of truth for the program
5. Add scheduling and ops tools (Calendly, Linear) as the team grows

The best stack is the one your team actually uses. Start lean, nail the workflows, and only add tools when you feel genuine pain without them.
