We chose SignalFire for their commitment to Al innovation, their unique XIR model, and their incredible network-including Chris Farinacci, former COO of Asana, who is joining our board to help scale Conveyor's Al-powered customer trust automation.

Chas Ballew

CEO, Conveyor

I chose Signalfire over other leading VC firms because of their long-term relationship mindset with entrepreneurs, a strong track record and continued experience with legaltech + AI investments, and a data and ecosystem AI platform, which is by far one of the strongest in venture.

Paul Lee

Co-Founder & CEO, Patlytics

SuperDial's deep RCM expertise, vertical focus, sophisticated voice AI technology, scalability, and the configurability of their prompts put them head and shoulders above the competition. Their focus on revenue cycle on the provider side, and claims and provider data management on the payor side, enables them to build deep IP and differentiation that is unparalleled in the market.

Tom Peterson

XIR at SignalFire, Former Co-Founder & COO of Evolent Health

With the rise of the digital economy, private equity consolidation, and inflationary pressures, it's extraordinarily difficult to operate a business. A decade into modern fintech, Main Street businesses are still guessing when it comes to finances. SignalFire shares our conviction that it’s time for a change, and they’re helping us create this new market together.

Aaron Bai

Co-Founder & CEO, Affiniti

We built Affiniti to meet SMBs where they already are—within the communities and associations they trust. These aren’t just distribution channels, but sources of credibility in long-overlooked industries. When your first customers come from listening, not ads, you quickly learn what truly matters—and that’s what makes our product resonate.

Sahil Phadnis

Co-Founder & President, Affiniti

What struck us first about Aaron and Sahil: real customer empathy that shows up in everything they build—from purpose-built fintech solutions to a trust-driven GTM that meets SMBs where they are. It’s a rare mix—and why we’re excited to back Affiniti.

Jonathan Lim

Partner, SignalFire

Starting the conversation with, "You’re incredible, and I want to be the best employer I can be for you" changes everything. It turns a meeting into a moment of trust.

Anita Modi

Co-Founder & CEO, Peer AI

We iterate on our product based on user feedback, so why wouldn’t we do the same for our culture? That’s how you keep your best people building with you.

Anita Modi

CEO, Peer AI

Whether it's using Claude to structure a compelling cover letter, research our Constitutional AI approach, or prepare for technical discussions, we want to see how candidates think with AI as a collaborator.

Nick Lewis

Head of Global GTM Recruiting, Anthropic

Candidates who don’t receive an offer should still walk away feeling respected and informed. The goal is for candidates to leave saying, "I didn’t get the job, but I’d still apply here again."

Heather Doshay

Talent Partner at SignalFire

At Anthropic, we created structure around authenticity, vulnerability and making space for disagreement. Regular company-wide AMAs, detailed postmortems of failed experiments, and forums for employee feedback (including anonymous ones) are institutionalized, making openness a habit.

Nick Lewis

Head of Global GTM Recruiting, Anthropic

If you have more than 200 inbound demo requests per month and think an AI workflow like this can raise your connect-to-show rates by at least 5%, the system likely pays for itself. Anything below that, and it’s usually cheaper to just coach SDRs more thoroughly and enforce SLA discipline.

Namrata Ram

VP Revenue Strategy & Operations Sales Development Pricing, Together AI

As the CEO, I still feel I should be that motivational coach for me company.

Itzik Cohen

CEO of PayZen

Insurance companies make the approval process challenging for specialty medications. Infusion providers, pharmacies, and health systems spend a lot of manpower on coverage and reimbursement verification, and prior authorizations, which could take weeks per prescription and lead to millions in bad debt. By leveraging AI, we saw an opportunity to build autonomous agents that can tackle these workflows more reliably, in just minutes.

Will Yin

Co-Founder & CEO, Mandolin

We always asked ourselves: “Why should AI tasks live outside the systems where human tasks already run?” By unifying them, we unlock 100 times the value and give SMBs the same leverage that Fortune 500s get from expensive custom AI builds.

Harry Qi

Co-Founder & CEO, Motion

In just a few years, a single human will manage hundreds of AI Employees completing thousands of tasks inside the Motion platform. Our vision has always been to help everyday businesses grow by letting AI handle the busywork, so humans can focus on what really matters.

Harry Qi

Co-Founder & CEO, Motion

Small business owners do not want another AI chat tool that requires hours of prompting. They want new customers.

The healthcare system has normalized leaving patients to figure things out themselves in their most vulnerable moments. That failure is costly, dangerous, and preventable.

Jeremy Gurewitz

Founder & CEO, Solace

Small business owners do not want another AI chat tool that requires hours of prompting. They want new customers.

Lucas Pellen

Co-Founder, Mega

We created our own strict model that grades us.

Amit Patankar

CTO of Blue Voice

Al is powerful but unpredictable. Human involvement ensures accuracy, adds emotional intelligence and empathy, and achieves the business results that matter most.

Aaron Lee

CEO of Smith.Ai

Essentially, top-tier degrees seem to not matter much. At 8 years, an engineer with a top-tier degree is only 3% more likely to be promoted than an engineer with no degree.

Based on the data across the industry, if you have been in your role for 2-3 years, you should be seeking a promotion internally or externally.
