Side-by-side review of BamSEC, Last10K, and Earnings Feed across real-time coverage, collaboration paths, and API surface area.
Welcome to the 2025 edition of our BamSEC vs Last10K comparison. Both incumbents dominate the “research the filing after it posted” workflow: BamSEC wins on cross-document search and curated tear sheets, while Last10K shines when you need ratio screeners, Excel-ready tables, and transcripts. Earnings Feed enters when you need streaming alerts plus dossier shortcuts.
Feature grid
| Capability | BamSEC | Last10K | Earnings Feed |
|---|---|---|---|
| Live filing detection | Refresh the activity feed manually | Poll API endpoints every few minutes | Streaming feed + Slack/email/webhook alerts in seconds |
| Document search | Multi-filing cross-search with highlights | Keyword search limited to individual filings | Filter feed by free text, then jump into dossier packets |
| Tear sheets / dossiers | Tear sheets with KPIs | Issuer pages with fundamentals + ratios | Real-time dossier with filings, holders, transcripts, and custom notes |
| API access | Limited; focus is UI | Full filings + fundamentals API, Excel downloads | Webhooks + REST endpoints for alerts, filings, and watchlists |

When to use each
- Stay on BamSEC for forensic digging through historic IPOs, scanning multiple documents for one clause, or prepping diligence binders.
- Stay on Last10K for quant screens, historical fundamentals, and Excel models tied to their API.
- Add Earnings Feed when the trading desk needs streaming awareness of 8-K, S-1, or 13D events, plus dossiers that consolidate filings, transcripts, and ownership shifts moments after they hit EDGAR.
Migration recipe
- Map the 20 most material issuers you monitor in BamSEC/Last10K.
- Create watchlists in Earnings Feed, subscribe them to Slack channels, and validate that every alert carries metadata (form, accession, acceptance time) you need for compliance tickets.
- Use webhooks to kick off Last10K API pulls or BamSEC exports so your historical store stays complete.
- Share dossier links internally so PMs can explore filings, transcripts, and holders without hunting across three tabs.
The takeaway: keep BamSEC and Last10K for their archival and modeling superpowers, but layer Earnings Feed on top so you never wait for an overnight scrape again.
