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’ve spent two decades writing proposals, bids, and funding applications—across SaaS, aerospace, consulting, and professional services.
Together, we’ve helped startups, scaleups, SMEs and corporates win over £125 million in grant funding. On the tender side, we’ve been part of winning teams that secured more than $1 billion in government and enterprise contracts. But even with all that success, we kept hitting the same problem: the tools were built to format documents, not close deals. There were no good options—so we made one. And we use it ourselves, every week.
Meet the founders
Simon Dutta — Co-Founder, Growth & GTM
Simon helps founders sharpen the narrative so reviewers say yes. With a background in marketing and growth, he’s helped teams win over $1B in public tenders and private sector contracts by getting the narrative right. At BidX, he works directly with founders — first-time and serial — to shape positioning, messaging, and strategy for high-stakes applications. Unlike most firms, we don’t outsource you to generalists. You work with us — the people who’ve actually won funding — to build something fundable, fast.
Aaron Mason — Co-Founder, Product & AI
Aaron builds the engine behind BidX. He’s spent 15 years designing AI systems that help teams win — not just automate. He’s helped hundreds of founders secure over £125M in non-dilutive funding — and personally won 40+ successful innovation grant applications for his own ventures. At BidX, he leads product and AI — combining automation with expert grant writers and former Innovate UK and Horizon Europe assessors. Unlike others, you won’t be handed off to juniors. Founders work directly with us to build proposals that win.
