How to run a retrospective or post-mortem as Event Agency Founders
After a 200-person corporate gala or a three-day conference wraps, you have six vendor email threads in Gmail, a debrief voice note you recorded in the Uber home, a Google Doc your second coordinator started but never finished, and a HoneyBook/Dubsado project that shows 'complete' but captures none of what actually went wrong. The retro either doesn't happen or happens once over a 20-minute Zoom call where everyone says 'it went great' and nobody writes anything down. Three months later you're quoting a similar event and you have no record of why the AV vendor was swapped last-minute or what the real labor hours were versus the estimate.
What you'll set up
Apps, data, and prompts
The combination of Starch apps, the data sources they pull from, and the prompts you use to drive them.
Meeting Notes captures your debrief call — connect Google Calendar so Starch syncs your scheduled events on a schedule and knows which meeting is the retro. Gmail is connected from Starch's integration catalog so the agent queries your vendor threads live during the debrief summary. Project Management and Knowledge Management are standalone Starch surfaces — no external sync needed. Google Drive can be connected from Starch's integration catalog so the agent pulls in any pre-existing debrief docs or run-of-show files live.

Henderson Corporate Retreat — March 2026 Post-Mortem
| AV vendor (original quote) | 4,200 |
| AV vendor (actual — emergency backup called day-of) | 6,100 |
| Catering overage (guest count revised 72 hours out) | 1,350 |
| Staff labor (actual vs. quoted) | 2,800 |
| Staff labor (quoted) | 2,200 |
| Total budget variance | 3,850 |
The Henderson Corporate Retreat was a 175-person two-day offsite at a hotel in Austin. Projected budget was $38,000; actual came in at $41,850 — a $3,850 overrun. The debrief call ran 28 minutes. Meeting Notes transcribed the whole thing and generated a summary in under two minutes: AV vendor no-showed at 7 AM load-in and a backup vendor was called at a $1,900 premium; catering was re-quoted when the client added 15 guests at day-minus-3; on-site staffing ran 3 hours over the estimate because the venue's freight elevator was slower than projected. Starch created four tasks from the retro: research two backup AV vendors with confirmed availability guarantees (assigned to founder, due in 5 days), update the catering contract template to include a 10% guest-count buffer clause (assigned to Jordan, due in 7 days), add freight elevator access time to venue intake checklist (assigned to founder, due in 3 days), and flag the $3,850 variance in the Henderson client file for reference in future similar proposals. The AV findings were added to the 'Vendor Lessons' page in the Knowledge Base. Two months later, quoting a similar 160-person Austin offsite, the founder pulled up that page in 30 seconds and added a $1,500 AV contingency line to the proposal without having to remember why.

We don't do formal debrief calls — it's usually just me and one coordinator texting after the event. Can Starch still help?
Does Starch connect to HoneyBook or Dubsado so the retro can reference what was actually quoted versus invoiced?
What happens to the knowledge base over time — does it get stale?
Is Starch SOC 2 certified? We sometimes handle client data in our retros.
We run 30+ events a year. Will the retro archive stay searchable at that volume?
Can Starch pull in the actual vendor invoices from Gmail to compare against what we quoted in the retro?
