What is Fountain?

Fountain is wiring AI agents across the hourly-hiring lifecycle, from sourcing to retention.

Fountain runs two parallel build-outs: an agent layer (Cue for recommendations, the Candidate AI Agent, and now Sam for post-hire satisfaction) and a sourcing-and-attribution stack centered on Source. Recent releases lean on closing the loop between ad spend and actual hires, and on extending automation past the point of hire into worker retention.

What is OpenCATS?

OpenCATS breaks a two-year quiet with v0.10.0, tightening attachment auth and form UX

OpenCATS, an open-source applicant-tracking system, ships rarely — its release history spans 2020 to 2026 with long gaps. The new v0.10.0 ends a roughly two-year quiet since the 2024 maintenance line, adding authentication on the attachments module, form-validation and default-company improvements, non-ASCII handling, and a JS back-button fix. Prior releases were predominantly security and PHP-compatibility maintenance.

Fountain vs OpenCATS: editorial side-by-side

F7.5

Fountain is wiring AI agents across the hourly-hiring lifecycle, from sourcing to retention.

◆ Current state

Fountain runs two parallel build-outs: an agent layer (Cue for recommendations, the Candidate AI Agent, and now Sam for post-hire satisfaction) and a sourcing-and-attribution stack centered on Source. Recent releases lean on closing the loop between ad spend and actual hires, and on extending automation past the point of hire into worker retention.

◆ Where it's heading

The product is expanding its AI agents from the front of the funnel toward the back: onboarding check-ins, satisfaction, and rehiring logic. Source is maturing into a full media-buying surface with channel-level cost data and server-to-server attribution. Expect agents to own more of each lifecycle stage and sourcing to become a spend-accountable channel.

◆ Prediction

Sam graduates from coming-soon to general availability, and Fountain ties its satisfaction signals back into rehiring and sourcing decisions to close the retention loop.

O2.5

OpenCATS breaks a two-year quiet with v0.10.0, tightening attachment auth and form UX

◆ Current state

OpenCATS, an open-source applicant-tracking system, ships rarely — its release history spans 2020 to 2026 with long gaps. The new v0.10.0 ends a roughly two-year quiet since the 2024 maintenance line, adding authentication on the attachments module, form-validation and default-company improvements, non-ASCII handling, and a JS back-button fix. Prior releases were predominantly security and PHP-compatibility maintenance.

◆ Where it's heading

The pattern is a community project moving in slow, security-conscious increments: authenticated attachments and earlier XSS/cookie hardening show steady attention to securing an aging codebase. v0.10.0 suggests renewed maintenance momentum rather than a feature pivot.

◆ Prediction

Expect continued infrequent releases focused on security hardening and PHP-version compatibility. A jump in cadence would be the signal to watch for renewed active development.
