# Codepost

*/Startups/Codepost*

## Startup Overview

This grading platform evaluates programming assignments by running hidden test suites and aggregating rubric-based peer feedback. Instructors define automated checks and qualitative scoring criteria, allowing the system to validate code execution while simultaneously coordinating structured human reviews.

Computer science educators face severe bottlenecks when evaluating complex coding projects, typically resorting to fragile, homegrown university scripts to handle submissions. Validating code requires measuring both functional correctness and structural quality, a dual requirement that overwhelms manual grading processes.

Unlike Gradescope Autograder or GitHub Classroom, the architecture is fully language-agnostic and deeply integrated into standard version control workflows. It processes assignments using real-world Git mechanics, capturing automated test results and peer evaluations in a single unified interface without restricting the curriculum to specific programming languages.

## Startup Offer

**Proof**:
- Targeting computer science departments aiming to reduce teaching assistant grading hours by up to 50%
- Designed to safely execute untrusted student code across 40+ programming languages
- Aiming to achieve 99.99% uptime during peak end-of-term submission floods
**Tiers**:
- Name: Course License · Price: ~$3–$8 per enrolled student · Inclusions: Unlimited assignments, standard language auto-grading execution, and peer feedback rubrics for a single active class.
- Name: Department Plan · Price: ~$12k–$25k/yr · Inclusions: Unlimited courses for an entire department, designed for campus LMS integration, SSO enforcement, and custom Docker container support for niche languages.
**Guarantee**: If the automated testing pipeline drops submissions or experiences downtime during a scheduled assignment deadline window, the current term's billing is fully refunded.
**Business Function**: ProvideService
**Objection Handlers**:
- Objection: Our TAs already use homegrown shell scripts. Rebuttal: Custom scripts break on edge cases and lack a unified UI for peer review; Codepost standardizes the pipeline securely.
- Objection: Students will game the system if they see the hidden tests. Rebuttal: Hidden tests execute in secure sandboxes and only return custom hint outputs, never exposing the test logic.
- Objection: We do not want students learning a new submission portal. Rebuttal: Codepost is designed to hook directly into standard version control, meaning students submit simply by pushing to their repository.

## Startup Brand

**Voice**: Academic precision paired with the direct brevity of developer documentation.
**Tagline**: Automate code grading and standardize peer feedback across any language.
**Icon Concept**: Clipboard
**Palette Intent**: institutional-cool
**Visual Identity**: The visual identity pairs structured grid layouts and monospace typography with academic slate and precise blue accents to bridge rigorous classroom grading with developer workflows.
**Archetype Reference**: the-sage

## Startup Buyer Chain

**Chain**: Codepost → Computer Science Professor → Teaching Assistants → Computer Science Students
**Gtm Motion**: Acquires users through bottom-up adoption by individual computer science instructors implementing automated testing for a single course, then expands to department-wide site licenses by standardizing peer-review rubrics across the curriculum.
**Agent Channel**: Intended to list in the OpenAI Actions registry and the GitHub Copilot extensions catalog as a callable code-evaluation endpoint, enabling AI teaching agents to trigger hidden tests and retrieve grading rubrics.
**Primary Channel**: Discovery relies on organic search for 'language-agnostic autograder' and targeted participation in academic computer science education communities like SIGCSE.

## Startup Proof Points

_Illustrative — target and order-of-magnitude estimate figures, not an achieved track record (this Thing is concept-stage)._

**Pilot Goals**:
- A single-term pilot in a 300-student introductory computer science course aiming to prove flawless auto-grading execution of untrusted code with zero dropped submissions.
- A two-month multi-class deployment testing the custom Docker container support for niche languages, targeting perfect uptime during scheduled assignment deadline windows.
**Target Metrics**:
- Target: 50 percent reduction in teaching assistant weekly grading hours.
- Aim: 99.99 percent uptime for the automated testing pipeline during end-of-term submission floods.
- Target: 0 reported instances of exposed hidden test logic or sandbox escapes.
- Aim: 100 percent successful execution of untrusted student code across 40 supported programming languages.
**Target Case Studies**:
- Large public university computer science department moving from homegrown shell scripts to standardized Docker-based auto-grading, targeting a 50 percent reduction in teaching assistant grading hours.
- Mid-sized private college introductory programming course implementing automated hidden tests and peer feedback rubrics to standardize grading consistency across 500 enrolled students without exposing test logic.
- Bootcamp coding academy integrating git-push submission workflows to eliminate proprietary portal training and achieve zero downtime during final project deadline windows.
**Testimonial Targets**:
- Lead Teaching Assistant highlighting how the unified UI for peer review eliminates the edge-case errors previously experienced with custom shell scripts.
- Computer Science Department Chair validating that the LMS and SSO integration securely standardizes the grading pipeline without creating new administrative IT overhead.
- Course Instructor confirming that the version control hook submission method allows students to submit via git push without learning a new proprietary portal.

## Startup Top Risks

**Risks**:
- Severity: existential · Description: University IT departments block deployment due to strict FERPA compliance requirements and existing enterprise contracts with Gradescope. · Mitigation Status: in-progress
- Severity: high · Description: Executing untrusted student code across arbitrary programming languages leads to container escapes or infrastructure compromise. · Mitigation Status: in-progress
- Severity: high · Description: GitHub or GitLab modifies their API rate limits or classroom integration policies, breaking the core version control workflow. · Mitigation Status: unmitigated
- Severity: moderate · Description: Sales cycles stall because individual professors lack purchasing power and department-wide adoption takes over twelve months. · Mitigation Status: unmitigated
