Build-in-public notes from a pre-seed team.
Progull is early. This page collects design notes, engineering updates and calls for design partners — not customer wins, funding rounds or attested audit reports.
Design notes and product updates.
Everything below is written by the founder and reflects the current state of the build. It will be replaced with real deployment evidence once we have design-partner results to share.
Founding Progull — building an agentic abend layer from scratch
Why a small, senior team is spending the next 12 months building the reasoning loop before onboarding any live production customer.
Testing on Hercules with synthetic SMF and JES corpora
Early development happens entirely against synthetic datasets in a sandboxed Hercules z/OS emulator. Here is how we set it up and what it lets us prove.
Design note: the Tiered Autonomy Model
Advisory, Approval and Autonomous — the three tiers we are building into the platform from day one, and why full autonomy is opt-in per abend family.
Design note: hybrid engine with domain agents
A centralized orchestration layer paired with subsystem-specific agents — JCL Agent, Db2 Agent, CICS Agent — behind a risk-based human-in-the-loop gate.
Seeking design partners for the 2026–27 pilot cohort
Following the 12-month build, we plan to onboard a small number of design-partner sites for a 6-month pilot at no charge. What we ask, what we bring.
