Feature Comparison

Ballista

Precision Hiring Manager Discovery

We do the detective work for you. Simply paste a job link, and our system identifies the top three most likely hiring managers or decision-makers for that role. We provide you with their names, scores indicating our confidence, the reasons for our selection, and their real mailing addresses. This eliminates hours of frustrating LinkedIn searches and guesswork, ensuring your resume reaches the right hands, not just a generic HR department.

Physical Mail Delivery on Premium Paper

Ballista transforms your digital resume into a tangible, professional package. We print your application on high-quality, 90lb bond paper, which feels substantial and impressive. It's then sent via USPS First-Class Mail in a flat envelope, arriving directly on the recipient's desk. Physical mail has a 90% open rate and completely bypasses automated resume filters and crowded email inboxes, making your application impossible to ignore.

Verified Human Effort & Proof of Delivery

Stand out from AI-generated spam applications. Every Ballista mailing includes a unique QR code on the cover letter. When scanned by an employer, it cryptographically verifies that a real human invested time and resources into this specific application. For added peace of mind, you can opt for Premium Certified Mail with tracking, which provides proof of delivery and shows the employer your serious commitment.

Flexible Credit-Based Pricing System

Ballista uses a simple credit system with no subscriptions or hidden fees. Purchase a pack of credits (which never expire) and use them for various services. A standard application with first-class mail costs 668 credits, while a premium tracked application is 1728 credits. You can also use credits for add-ons like smart cover letter personalization or custom brand design. This flexible model lets you pay for what you need, whether it's one application or a full campaign.

Use Cases

Ballista

The Senior Professional Targeting High-Value Roles

For executives and senior specialists applying for roles over $150k, competition is fierce and first impressions are everything. Ballista allows you to demonstrate unparalleled initiative and professionalism. Sending a physically impressive, directly-targeted application to a C-level executive or department head can break through the corporate layers and start a conversation that an online form never could.

The Startup Job Seeker

Startups move fast and value hustle. Applying through a standard portal for a Product Manager or growth role can leave you as just another faceless candidate. Using Ballista to mail your resume directly to the founder or head of product shows the exact kind of proactive, creative, and determined mindset that startup cultures cherish, significantly increasing your chances of getting a direct response.

The Candidate in an Oversaturated Market

If you're applying for marketing roles in a hub like NYC or for popular remote positions, you're often competing with 500+ applicants. When everyone uses the same digital channels, your application becomes a statistic. Ballista's physical mail approach ensures you are the only paper resume on the hiring manager's desk that day, creating a memorable tactile experience that digital files can't match.

The Career Changer or Unconventional Candidate

If your background isn't a perfect linear fit for a role, ATS systems and hurried HR screeners might filter you out prematurely. A Ballista mailing allows you to tell your story directly to the person who understands the role's nuances. The cover letter and verified effort QR code help you contextualize your experience and passion, framing your unique journey as an asset rather than a liability.
