What is Prospero?

Prospero is turning proposals from documents into instrumented, reusable assets.

Prospero builds and sends business proposals, with templates, a content library, e-signature and CRM connections around them. The releases over the past nine months form a steady, unhurried cadence of practical additions: catalogs and saved deliverables for reusing priced line items, content locking to protect approved sections, bulk actions across proposals, form builder fields, HubSpot and Make.com integrations, and now page-by-page analytics on how prospects read a proposal.

5.0

OpenEMM 26.11 reaches GA eight days after its beta.

◆ Current state

OpenEMM released 26.11.169 as the general-availability build of the 26.11 line on November 12, eight days after the 26.11.136 beta. The notes list only the frontend version. The 26.05 line it replaces reached GA in July and has had only frontend builds since.

◆ Where it's heading

OpenEMM keeps its twice-yearly cycle: a beta, a GA, then months of frontend-only maintenance builds. The notes never say what a line changes, so the cadence is the only visible signal.

◆ Prediction

Expect frontend-only 26.11 maintenance builds over the coming months; the entries give no hint of feature content.

Prospero is turning proposals from documents into instrumented, reusable assets.

◆ Current state

Prospero builds and sends business proposals, with templates, a content library, e-signature and CRM connections around them. The releases over the past nine months form a steady, unhurried cadence of practical additions: catalogs and saved deliverables for reusing priced line items, content locking to protect approved sections, bulk actions across proposals, form builder fields, HubSpot and Make.com integrations, and now page-by-page analytics on how prospects read a proposal.

◆ Where it's heading

Two consistent threads. The first treats proposal content as a reusable asset rather than a document — catalogs, saved deliverables, locked sections and templates all reduce how much of each proposal is written from scratch. The second instruments what happens after the proposal is sent, moving from delivery and signature toward telling a salesperson which pages held attention and which were skipped. The AI writing assistant sits alongside both without yet being connected to either.

◆ Prediction

Engagement data is now captured per page but presented for a human to read; the natural next step is acting on it — alerting when a prospect revisits pricing, or feeding the analytics back into template suggestions.
