Questions & Answers

As answered by people managing Postmark and Blastra.

Which are the primary technologies used for building your product?

Blastra's answer:

Modern web stack with AI/LLM integration for content generation, cloud infrastructure for scalability, and automated workflow systems for managing submissions across multiple platforms.

How would you describe the primary audience of your product?

Blastra's answer:

Blastra serves B2B software companies that need to manage product narrative across third-party platforms. Common users include small teams shipping frequent product updates who struggle to keep the world informed, large companies with multiple existing listings but no system for keeping them centralized and current, companies coming out of stealth establishing third-party presence for the first time, post-funding companies building credibility with enterprise buyers through reviews and badges, and companies going through a rebrand or pivot needing consistent updates across every platform.

Why should a person choose your product over its competitors?

Blastra's answer:

Blastra provides a centralized dashboard where you see every listing, its status, credentials, and profile links in one place. It handles submissions compliantly, following each directory's specific policies and requirements. After the work is done, you retain full access to all accounts. The platform also supports multi-product companies with separate profiles mapped to different directory taxonomies, something most alternatives don't address.

What makes your product unique?

Blastra's answer:

Blastra focuses on ongoing listings management rather than one-time submissions. It combines AI automation with human operators to handle the full lifecycle—discovery, creation, optimization, and maintenance—across 25+ high-quality directories. Listings are individually crafted, reviewed by humans, and kept current over time with decay detection and regular updates.

What's the story behind your product?

Blastra's answer:

Blastra was built to solve a problem most B2B software companies recognize but nobody internally wants to own: managing presence across dozens of directories with different portals, requirements, and review cycles. Listings go stale, new directories get ignored, reviews go unanswered, and earned badges go unnoticed. As buying moves to AI, LLMs increasingly use these catalogs for training and live search, making accurate, verified listings even more critical. Blastra operates as the equivalent of a dedicated team member responsible for third-party presence at a fraction of the cost of a part-time hire.

Who are some of the biggest customers of your product?

Blastra's answer:

Blastra's largest customers are companies with 200+ people with multiple products in their portfolio.
