Why Bidx.ai?
What We Do
We built BidX because proposals weren’t closing. You have a great call. Then you send a PDF, a signature link, or an email thread. The buyer prints it, signs it, scans it—if they don’t give up halfway. You follow up. They forget. And the deal dies somewhere in their inbox. BidX replaces that friction with one smart, digital proposal—personalised, branded, tracked, and ready to sign and pay. It’s what we wanted for ourselves. So we built it.
Why We Built It
We have spent over 20 years crafting high-stakes proposals across SaaS startups, aerospace firms, consulting businesses, and professional services.
Together, we have secured over £125 million in grant funding and contributed to winning more than $1 billion in government and enterprise contracts. Despite our success, one issue persisted: traditional proposal tools were designed for formatting documents rather than closing deals.
We envisaged something better. AI-driven proposals designed specifically to convert. BidX is that vision brought to life, and now we use it ourselves every single day.
