What is Gumloop?
Gumloop 13.6 gives admins one set of rules for every tool an agent touches.
Gumloop ships a numbered release every few days. 13.0 rebuilt the agent harness, 13.3 published agents to Okta, 13.4 cut agent tokens per step by about 40% and 13.5 added live multi-user tasks. 13.6 extends admin guardrails from connectors to every tool, redacts card numbers and passwords before models see them, warns when agent instructions contain credentials, adds browser allow and block lists and domain-restricted API keys, and introduces Workforce Atlas, a board of every agent and skill in the organization.
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.
Gumloop vs Prospero: editorial side-by-side
Gumloop
6.3MKT AUTO
Gumloop 13.6 gives admins one set of rules for every tool an agent touches.
◆ Current state
Gumloop ships a numbered release every few days. 13.0 rebuilt the agent harness, 13.3 published agents to Okta, 13.4 cut agent tokens per step by about 40% and 13.5 added live multi-user tasks. 13.6 extends admin guardrails from connectors to every tool, redacts card numbers and passwords before models see them, warns when agent instructions contain credentials, adds browser allow and block lists and domain-restricted API keys, and introduces Workforce Atlas, a board of every agent and skill in the organization.
◆ Where it's heading
Since 13.2 the releases have moved from what agents can do toward how a company controls them. 13.6 is the broadest step yet: approval rules, data redaction and secret handling now cover all agent activity, which is what security teams ask for before a wide rollout.
◆ Prediction
Expect Workforce Atlas to leave beta with more tags and reporting, and more enterprise controls such as audit exports built on the new guardrail records.
Prospero
0.0MKT AUTO
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.
