Penna

Penna targets the bottleneck most sales and services teams hit at the end of a deal: assembling a polished, on-brand proposal. Rather than starting from a blank document, users describe the deal and Penna's custom-tuned AI model drafts a complete proposal in around half a minute, with tone, structure, and content adjustable to fit a particular client, industry, or brand voice. Support for more than 29 languages makes it practical for teams selling across borders.

The platform is more than a text generator. Multiple stakeholders can edit, comment, and version a document at the same time, and successful proposals can be duplicated in one click for reuse. Penna sends proposals as password-protected web pages or as classic PDFs, and it reports when a client opens or accepts one so the salesperson can follow up at the right moment. Custom domains keep proposal links on-brand.

On the operational side, Penna integrates with CRMs, payment gateways, and invoicing systems so client data stays in sync and one-time or recurring multi-currency payments can be collected directly from a proposal. E-signatures are designed to comply with eIDAS in the EU and ESIGN/UETA in the US, with IP address, timestamp, and consent captured for the audit trail. Proposal data is encrypted with AES-256/AES-128 via OpenSSL, and Penna states that it cannot read customer proposal text; the company references CCPA, GDPR, and ePrivacy alignment. Pricing starts at $20 per member per month billed annually, after a 14-day trial and with a 10-day money-back guarantee.
