Feature Comparison
Ballista
Decision Maker Discovery
Ballista's proprietary technology analyzes job listings and company data to identify and suggest the top three most relevant hiring managers or decision-makers for a given role. It provides the individual's name, their likely relevance score, the reasoning behind the suggestion, and a verified physical mailing address. This eliminates the hours of research typically required to find the correct contact person, ensuring the application reaches someone with direct hiring influence rather than a generic HR department inbox.
Physical Mail Delivery & Premium Presentation
The service prints uploaded resumes and cover letters on thick, professional-grade 90lb bond paper (8.5x11 US Letter size) and dispatches them via USPS First-Class Mail, with delivery typically within 5-7 business days. This method capitalizes on the high open rate of physical mail and ensures the application materials have a substantive, high-quality feel. The tangible package stands in stark contrast to the flood of identical PDFs in an email inbox, commanding immediate attention and conveying a significant level of candidate effort and seriousness.
Verified Human Effort & Proof
To combat the perception of AI-generated spam and prove genuine candidate interest, Ballista includes a unique "Verified Human Effort" feature. Each mailed packet contains a QR code that employers can scan. This code leads to a cryptographically signed verification page (using Ed25519) that details the cost and time invested by the candidate in the application. This provides tangible, third-party proof that the application is a targeted, human-driven effort, adding a layer of credibility and trust.
Flexible Credit-Based Pricing System
Ballista operates on a transparent credit system rather than rigid subscriptions. Users purchase packs of credits (which never expire) and spend them on various service components. A standard application sent via first-class mail costs 668 credits, while a premium application with certified mail tracking costs 1728 credits. Additional features like smart cover letter personalization, brand design, or contact extraction cost small amounts of credits. This allows users to pay for exactly what they need and mix-and-match services for different applications.
About Perkoon
Unlimited Free Peer-to-Peer (P2P) Transfers
Perkoon's flagship feature is its unlimited, free file transfer service using WebRTC-based peer-to-peer technology. When both the sender and recipient are online simultaneously, files are transmitted directly between their web browsers. This method imposes no file size limits, requires no user accounts, and ensures high privacy as the data never traverses Perkoon's servers. The operational cost of this direct streaming is negligible for the company, which allows them to offer it as a permanent free service, fundamentally distinguishing it from competitors that use "freemium" models with strict caps.
Encrypted Cloud Storage for Offline Recipients
To address the common scenario where a recipient is not immediately available, Perkoon offers encrypted cloud storage as a paid feature. Files are securely uploaded to Perkoon's servers, encrypted, and held until the recipient is ready to download them. The company is transparent that this is the only paid component of its service, as it honestly reflects the real costs of maintaining server infrastructure, data storage, and bandwidth, creating a sustainable business model without hidden fees or data monetization.
Native AI and Automation Integration
A defining and forward-thinking feature of Perkoon is its built-in support for AI agents and automation scripts. The service exposes a client-side JavaScript object (window.__perkoon) that provides a structured API, allowing automated tools to interface with the file transfer process programmatically. This eliminates the need for unreliable DOM scraping, making Perkoon a first-class citizen in automated workflows, data pipelines, and AI-assisted operations where manual browser interaction is impractical.
Privacy-First Design and Transparent Operations
Perkoon is architected with a privacy-first philosophy. For P2P transfers, the company has zero access to file content or metadata. For cloud storage, files are encrypted on the client side or on Perkoon's servers. The service explicitly does not scan, analyze, or sell user data. This commitment is coupled with radical transparency about its business model, browser compatibility (noting limitations in Firefox and Safari), and the clear rationale behind what is free versus what is paid, fostering user trust.
Use Cases
Ballista
Breaking Into Competitive Senior Roles
For senior professionals (e.g., remote roles over $150k, Product Managers at startups, Marketing Directors in NYC), competition is fierce and applications are numerous. Ballista is ideal for these candidates to cut through the noise. Sending a physically mailed, high-quality application directly to a department head or VP demonstrates executive-level initiative and ensures their credentials are reviewed outside the standard, crowded digital pipeline, making a powerful statement of intent.
Overcoming ATS and Algorithmic Filters
Job seekers who repeatedly apply online without receiving interviews are likely being filtered out by automated systems before human eyes ever see their resume. Ballista provides a direct solution to this modern problem. By using physical mail that completely bypasses LinkedIn Easy Apply, Indeed, and company career page ATS software, candidates ensure their application lands on a desk, not in a digital spam folder, forcing a human evaluation.
Career Changers or Non-Traditional Candidates
Individuals transitioning industries or with unconventional career paths often struggle to get past keyword-scanning bots that prioritize specific linear experience. Ballista allows these candidates to tell their story directly to a decision-maker via a personalized cover letter and resume. The novelty and effort of a mailed application can prompt a hiring manager to give a more holistic review of transferable skills and potential, rather than a binary algorithmic pass/fail.
International Candidates Targeting US Jobs
As Ballista accepts job links and resumes from anywhere in the world but mails to US addresses, it is a powerful tool for international job seekers. It allows them to have a local, physical presence in the hiring process without needing a US mailing address themselves. This levels the playing field, making their application appear as immediate and committed as a local candidate's, while they manage the entire process remotely.
Perkoon
Sending Large Media Files to Clients
Freelance videographers, photographers, and designers can use Perkoon's unlimited P2P transfer to send multi-gigabyte project files, raw footage, or high-resolution image sets directly to clients. This bypasses the restrictive file size limits of email attachments or free tiers of other services, and the direct transfer ensures fast speeds and privacy without the files being stored on an intermediate server.
Asynchronous File Sharing for Distributed Teams
Remote teams and collaborators across different time zones can utilize Perkoon's encrypted cloud storage. A team member can upload a file to the cloud, and recipients can download it at their convenience, regardless of the sender's online status. This is ideal for sharing daily build files, documentation, or reports without requiring real-time coordination.
Automated Data Pipeline and Backup Scripts
Developers and system administrators can leverage Perkoon's native API for automation. Scripts can be written to automatically upload log files, database dumps, or backup archives to Perkoon's cloud storage as part of a cron job or CI/CD pipeline. The CLI tool and window.__perkoon API enable these transfers without manual browser interaction, making it a robust component in IT infrastructure.
Privacy-Conscious Personal File Sharing
Individuals who are wary of large tech companies profiling their data can use Perkoon for personal file sharing. Whether sending sensitive documents, personal videos, or a collection of files to family and friends, the P2P option guarantees that the data is only seen by the intended recipient, aligning with a strong personal privacy ethos.
Overview
About Ballista
Ballista is a specialized service engineered to revolutionize the job application process by leveraging the tangible power of physical mail. In an era dominated by digital Applicant Tracking Systems (ATS) and online portals where resumes become mere data points, Ballista provides a strategic countermeasure. Its core function is to identify key hiring decision-makers within a target company and deliver a candidate's resume and cover letter directly to their desk via USPS First-Class Mail. This approach is designed to bypass the automated "black hole" of online applications, where AI filters and high volumes often prevent human review. The service is tailored for proactive job seekers across all industries and experience levels, particularly those applying for competitive roles in the United States, who are frustrated by the lack of response from digital submissions. Ballista's fundamental value proposition is the restoration of a personal, human touch in the initial application phase, significantly increasing visibility and demonstrating a candidate's unique initiative and determination in a way a digital file cannot. By handling the entire process—from precise contact discovery to professional printing on premium 90lb paper—Ballista empowers individuals to stand out as a physical presence in a recruiter's workflow, thereby transforming their application from an invisible digital entry into a memorable, tactile impression.

Uniquely, Perkoon is architected for interoperability in the age of automation, featuring native APIs that allow AI agents and scripts to interact with the service directly without inefficient screen-scraping.

Frequently Asked Questions
Ballista FAQ
How does Ballista find the correct hiring manager?
Ballista employs advanced data scraping and organizational analysis algorithms. When you paste a job link, the system cross-references company data, professional networks, and role specifics to identify individuals most likely to be involved in the hiring decision for that position. It provides a shortlist of suggestions with relevance scores and explanations, allowing you to select the most appropriate target based on the provided intelligence.
What is included in the "Verified Human Effort" feature?
This feature provides cryptographic proof that your application was a genuine, human-driven effort. Each mailed cover letter includes a QR code. When scanned, it leads to a unique, tamper-proof webpage signed by Ballista. This page verifies the monetary cost and approximate time you invested in that specific application, demonstrating to the employer that you used a targeted tool for outreach, not an AI mass-mailing service.
Can I track my mailed application?
Yes, tracking is available as a premium option. A standard application is sent via USPS First-Class Mail without tracking (668 credits). For 1728 credits, you can upgrade to a Premium Application, which uses Certified Mail and includes tracking with proof of delivery. This allows you to confirm exactly when your application packet was delivered to the hiring manager's address.
What if I don't use all my credits at once?
Credits purchased from Ballista never expire. You can buy a pack (like the Single, Triple, or Campaign pack) and use the credits at your own pace, whether you send one application this month and several more six months later. The flexible system is designed for job seekers who may apply intermittently, ensuring you only pay for what you use without any subscription pressure or loss of unused funds.
Perkoon FAQ
Is the peer-to-peer transfer really free forever?
Yes, Perkoon's peer-to-peer (P2P) file transfer service is completely free with no file size limits and is intended to remain free indefinitely. The company's rationale is that the direct browser-to-browser streaming technology incurs negligible infrastructure costs for them, as they do not host or relay the file data. This allows them to offer it as a sustainable free service, distinct from their paid cloud storage feature.
What happens if the recipient is not online when I send a file?
If the recipient is offline at the time of transfer, the P2P connection cannot be established. For this scenario, Perkoon offers its encrypted cloud storage service, which is a paid feature. You can upload the file to Perkoon's servers, where it is encrypted and held securely. The recipient then receives a link to download the file at their convenience, once they are online.
How does Perkoon ensure my privacy?
Perkoon ensures privacy through its architecture. For P2P transfers, files are streamed directly between users' browsers using WebRTC, meaning the data never passes through Perkoon's servers and is inaccessible to them. For cloud storage, files are encrypted on their servers. The company has a strict policy of not scanning, analyzing, or selling user data or metadata, making privacy a core operational tenet.
Can I use Perkoon with automation tools or AI agents?
Absolutely. Perkoon is uniquely designed for automation. It provides a client-side JavaScript API (window.__perkoon) that allows AI agents, bots, and custom scripts to interact with the file transfer service programmatically. This means these tools can initiate and manage transfers directly through the API without the need for visually scraping the website, enabling seamless integration into automated workflows.
