What nusii does
Nusii Proposal S.L. is a privately held, bootstrapped software company headquartered in Spain (Madrid) that builds Nusii, a cloud-based proposal management platform used by agencies and professional services firms to create, send, track, and e-sign business proposals. The product is built around a focused, proposal-specific workflow: reusable content sections and full templates, dynamic client variables, smart email and in-app notifications on prospect opens/views/signatures, analytics on proposal status and conversion, optional pricing sections that let buyers select tiers, multi-currency and tax handling, and legally binding in-browser e-signatures with multi-signature support. Underlying the application is a REST API and webhooks platform (documented at developer.nusii.com) that enables programmatic proposal creation and CRM-bound workflows, alongside 20+ native integrations spanning HubSpot, Pipedrive, Stripe, Slack, Intercom, Zapier, Make, Integrately, and Pabbly. Nusii is localized in 35 languages and supports both monthly and annual billing.
The company operates a hybrid product-led growth and lightweight sales-assisted GTM: customers sign up via nusii.com for a 14-day free trial with no credit card, then subscribe to the Agency plan at $49/month (including 3 user seats, CRM integrations, and a custom proposal domain) with additional seats at $19/month each. There is no feature gating across tiers and a 60-day money-back guarantee is offered. Target customer segments include marketing and creative agencies, in-house sales teams, SaaS companies, and construction firms. The platform reports 6,985 companies on Nusii as of Q1 2026, with a stated 45.1% proposal acceptance rate across 5,596 proposals sent (compared to a 21% industry benchmark), and holds a 4.5-star rating on G2. The company was founded circa 2011 by Michael Koper, with Nathan Powell as co-founder, and remains self-funded with no external investors and no acquisition history.

nusii competitors and assessment
Company assessmentEmerging players
- Loopio: Loopio is a proposal response management platform that helps teams answer RFPs and security questionnaires. It targets a similar buyer (sales and proposal teams) but focuses on RFP libraries rather than Nusii's outbound proposal creation workflow.
Direct peers
- Qwilr: Qwilr is a proposal and document platform known for interactive, web-based proposal pages and analytics. It serves similar agency and B2B sales buyers to Nusii and is named explicitly on Nusii's competitor pages.
- PandaDoc: PandaDoc is a venture-backed document automation platform that combines proposals, contracts, e-signatures, and CPQ. It directly competes with Nusii for SMB and mid-market sales teams, though at a larger scope and price point.
- Better Proposals: Better Proposals is a UK-based proposal tool offering templates, e-signatures, and tracking for agencies and sales teams. It targets the same horizontal SMB-and-agency buyer as Nusii and is featured on Nusii's competitor comparison pages.
- ClientPoint: ClientPoint (formerly Quote Roller) is a sales proposal and document automation platform serving enterprise and SMB sales teams. MarkNet Group, a Nusii case study, replaced Quote Roller with Nusii, signaling the close product overlap.
- Bidsketch: Bidsketch is a long-standing proposal software focused on agencies and freelancers, with reusable templates and e-signatures. It overlaps with Nusii's agency-segment core market and is listed in Nusii's comparison content.
- Proposify: Proposify is one of the most direct competitors to Nusii, offering proposal creation, tracking, e-signatures, and templates aimed at agencies and sales teams. Nusii's own SEO strategy explicitly targets 'Proposify alternatives' searchers, underscoring the head-to-head positioning.
Broad incumbents
- Jotform Sign: Jotform Sign (formerly JotForm Sign) provides e-signatures and form-based document workflows that overlap with Nusii's proposal signing use case. It is a broader forms-and-signatures incumbent rather than a proposal-specialist.
- HoneyBook: HoneyBook is a broader client management and proposal platform aimed at creative SMBs, agencies, and freelancers. It overlaps with Nusii's agency segment but extends into contracts, invoicing, and project management.
- DocSend: DocSend (now part of Dropbox) is a document sharing and tracking platform widely used for sales proposals and pitch decks. It competes with Nusii's tracking and analytics story but is positioned as a broader document-sharing tool.
