We are solving a huge problem in financial services that has been lying unsolved for decades. All major payment systems (including wallets ) require two sided onboarding i.e. Payor and Payee need to onboard before they can transact. We have built a way to generate and transmit Digital Payments without onboarding the Payee/Recipient. This is huge in terms of bringing traditional paper and cash payments online. Add to that, we've figured out a clever way to monetize from both sides thereby changing the financial equation from Customers paying us to us paying our customers cash back from card fees! Our investors, whom we call our "believers," include Tim Draper, Adam Draper (Tim Draper's family), Naval Ravikabt through his AngelList Maiden Fund, co-founder of Intuit and more! Institutional investors include a top 4 bank and top 5 insurance company. Checkbook lets businesses move away from paper to deliver Digital Checks directly to a recipients email. This allows businesses to keep all their existing Accounts Payable (or Accounts Receivable processes) in place while moving to a completely online solution. All you need to send a check is the name and email of the recipient along with the amount you are sending. Recipients do not need to sign up for any service, download any app or pay any fees to receive payments. Digital Checks can be deposited and cashed online after instantly verifying banking credentials. No more paying high % based transaction fees on credit and debit cards or sharing sensitive bank account and routing numbers to payor.

Briidge.one, builds applied AI into how professional firms actually operate, not as another bolt on subscription but as systems grounded in a firm's own record, running inside the workflows people already use and owned outright once we hand over the keys. Another AI subscription doesn't change a firm. AI changes a firm when it runs inside the actual work, grounded in the firm's own data. Most professional firms, MSPs, private equity, investment firms, law firms, real estate, other professional services carry client relationships and institutional knowledge scattered across 5-10, sometimes 15 disconnected tools. Hours leak, records fragment and decisions wait on someone's memory instead of on data that should already be there. How we work We're a company, not a subscription. Every engagement runs through five stages: 1.Diagnose- an audit of how the firm actually operates, run by the people who will build the solution 2.Design- a roadmap naming which workflows, in what order, and what each is worth 3.Build- AI grounded in the firm's record, shaped to the workflow rather than a template 4.Integrate- connected to the tools the firm already runs, so one record moves instead of being retyped between systems 5.Improve- iteration after handover, sized to what's at stake. We build on the platforms professional firms already rely on Atera, ConnectWise, NinjaOne, HaloPSA, Datto, Autotask, DealCloud, Affinity, Datasite, Intralinks, Carta, PitchBook, Clio, iManage, NetDocuments, DocuSign, Yardi and MRI rather than asking firms to rip out what already works. What we put our name on: No outside logos to borrow. Clients own the code, the schema and the data outright with documentation complete enough for another team to take over. No lock in, nothing trained on a client's record and an exit built into every engagement from day one. We're building the team that will define what applied AI looks like for the firms that run the professional world.
