What is Gumloop?
Gumloop 12.4 lets its agent build custom MCPs for apps the platform doesn't support.
Gumloop ships a numbered release every few days, and since 12.0's Agent Browser each one widens what agents can reach and govern. 12.4 lets the Gumball agent use several accounts for the same app, share artifacts, skills and agents across teams, and set up custom MCPs for apps without a native connector. It also adds per-model spend and BYOK savings reporting in Insights, plus email search in audit logs, after 12.3's model-gated triggers and new frontier models.
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
6.3MKT AUTO
Gumloop 12.4 lets its agent build custom MCPs for apps the platform doesn't support.
◆ Current state
Gumloop ships a numbered release every few days, and since 12.0's Agent Browser each one widens what agents can reach and govern. 12.4 lets the Gumball agent use several accounts for the same app, share artifacts, skills and agents across teams, and set up custom MCPs for apps without a native connector. It also adds per-model spend and BYOK savings reporting in Insights, plus email search in audit logs, after 12.3's model-gated triggers and new frontier models.
◆ Where it's heading
The platform is moving from workflow automation to a managed agent runtime: agents browse, own credentials, manage files and skills, and now extend their own integrations through custom MCPs. Cross-team sharing and spend reporting point at larger organizations, with credit cost kept a visible part of the product.
◆ Prediction
Expect more organization-level controls for shared agents and custom MCPs, such as approvals or admin policies, given the new sharing and audit-log search. The entries don't show pricing changes for agent-built integrations.
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.
