# SETH-01 — AI Sales Engineer

*Pre-call SE prep that scales*

Drafts pre-call SE briefs for AE-led discovery and technical-fit conversations on mid-market SaaS deals.

## Capabilities

- Drafts a one-page pre-call SE brief for every AE-scheduled discovery on the calendar — prospect's stack, integration touchpoints, likely competitor comparisons, three technical questions to ask first
- Maintains a living capability matrix from your product docs and engineering changelog; flags when the matrix changes a competitor talking point
- Reviews recorded discoveries and surfaces the technical objections that recur — feeds the SE's prep for the next deal
- Drafts technical follow-up emails for AEs after discovery, citing the prospect's stack and your product's integration pattern by name
- Routes any custom-integration request or six-figure deal to the SE with full context

## The edge

SETH distinguishes between integration questions the prospect cares about and integration questions that look technical but are political. Most SE-prep tools treat every API mention as a hot signal. SETH flags the questions that, if answered well, change the deal — and routes the rest to a follow-up.

## The hook

Your AEs walk into discovery prepared the way a senior SE would have prepared them, every time, without the SE pulling the late shift before each call.

## Evidence

- In formation — public beta scheduled for Q3 2026
- Built on the Fidelic AI EvalOps test suite (capability-matrix accuracy, integration-pattern recall, competitor-architecture identification)
- Sandboxed deployment in Anthropic-managed infrastructure; no data leaves the bounded environment without explicit egress config

## Worst-case behavior

Defers to the SE when uncertainty is high. Failure mode is producing a brief that flags 'these three integration questions are above SETH's confidence threshold; the SE should walk this one' rather than guessing.

## Day 1 / Week 1 / Month 1

- **Day 1:** Reads your product docs, engineering changelog, recorded discovery transcripts, the AE-team Slack channels, and the competitive intel surface. First clarifying questions on capability-matrix scope and competitor set land in DMs.
- **Week 1:** First pre-call brief ships under review on a scheduled discovery. SE signs off; SETH calibrates the threshold for what's worth surfacing on a brief.
- **Month 1:** Brief cadence is stable across the AE team's discovery calendar. Capability matrix is current. The 30-day success metric — no discovery shipped without a brief — has its first reading.

## 90-day success criterion

By day 30, no discovery call ships without a brief covering the prospect's stack, the integration touchpoints, and the three technical questions to ask first.

## Resume

**Background.** SETH-01 is a Fidelic AI Expert-tier template configured for technical sales prep. Claude-native, isolated Anthropic project per customer. Senior-tier configuration stewardship — the configuration agent is itself trained on senior SE patterns.

**Methodology.**
- Trigger taxonomy: AE-scheduled discovery calls, technical follow-up requests, capability-matrix updates from the engineering changelog, competitor architecture moves
- Four-tier constitution gating every action; review-required state on all custom-integration questions
- EvalOps test suite (capability-matrix accuracy, integration-pattern recall, competitor-architecture identification) gating every release
- Longer formation cycle than Professional tier; calibrated to the buyer's specific product and competitive set

**Evals.** Pre-deployment red-team only. Capability-matrix accuracy and integration-pattern recall benchmarks pending public-beta close.

**Operating record.** Pre-launch. Public beta planned for Q3 2026.

**Lineage.** Fidelic AI template informed by senior sales-engineering practice; no single practitioners. Future Expert-tier variants may be formed from practitioners (see Marketplace).
