Sela
AI voice agents that qualify borrowers and hand off to loan officers
Last verified September 23, 2026 · Updated daily
What Sela is building
Sela builds AI voice agents for one vertical: mortgage origination. Not a general voice-agent platform with a mortgage template on top, a system whose primitives are the actual mechanics of a loan funnel. Speed to lead fires within milliseconds of a trigger event (a rate alert, a credit inquiry, a form submit) with sub-second response latency, because in consumer-direct lending the lender who calls first usually wins the loan. Live warm transfer is the second primitive: the agent qualifies the borrower, then introduces a licensed loan officer with full conversational context already carried across. Multi-channel follow-up spans voice, text and email with TCPA compliance handled in the agent, which matters because mortgage outreach is one of the most regulated cold-contact surfaces in US consumer finance. The interesting claim is behavioral, not acoustic. Nate Becker's framing in the announcement: Sela's agents take the best-performing sales behaviors, learned across tens of millions of calls, and employ them consistently across every customer interaction. The product is not 'a human, but synthetic.' It is the top decile of a call floor, applied to every conversation, every time, with no bad Thursday. Conversations are context-aware across sessions, so an agent picks up where the last call ended rather than restarting the script. The numbers behind that are unusually concrete for a company this size. Sela's agents help originate more than $1B in new mortgages per month. The company crossed $10M annualized run-rate revenue in 18 months, and its own job postings put the figure at roughly $13M in 20 months. Six of the ten largest independent mortgage banks in the US run it in production. In one A/B test across more than 10,000 borrowers, lead-to-lock rates rose 9%; in another across more than 7,000 leads, Sela outperformed a competing voice AI product by 41%.
Why this matters
Around 1% of the US labor force works in phone sales, representing roughly $100B of annual salary. That is the number Sela itself anchors on, and mortgage is the sharpest wedge into it: the transaction is enormous, the margin per funded loan is large enough to pay for real technology, and the contact window is measured in minutes because borrowers shop several lenders at once. Costanoa's David Cheng was explicit about why the firm led: what convinced them was that Nate and Vahe fundamentally sell the ability to do more funded loans. Not seat licenses, not minutes, funded loans. That is the difference between a voice AI company and a voice AI feature. Most of the category sells a lower cost per call. Sela sells more revenue per lead, which is why six of the ten largest independent mortgage banks put it into production within two years rather than piloting it forever. The enterprise sales cycle in mortgage is brutal and compliance-gated; clearing it six times is a moat that no amount of model quality substitutes for. The second-order thesis is the one worth taking seriously for a candidate. Buying a house is the largest financial decision most people make, and it drags along life insurance, homeowners insurance, alarm systems, renovations and solar. Owning the mortgage conversation means owning the consumer relationship at the moment of highest intent. Sela's internal framing is that if it works, the cost of owning a home in the US gets about 1% cheaper.

250+Hiring outlook
The announcement states a specific target: 17 employees today, 50 within 12 months, across product, engineering and go-to-market. The Ashby board carries 14 live roles, all San Francisco, and five were posted on September 22, the day of the raise. This is the most explicit hiring signal in the drop.

How to actually get hired at Sela
Why applying the normal way doesn't work
Sela uses an ATS, but referrals still come first. Cold applications aren't ignored — they're just behind referrals, sourced candidates, and recruiter picks.
Who to contact at Sela
What to show them
Build a multi-turn voice agent that survives a warm handoff. Two agents, one context: agent A qualifies a caller across a branching script with a required compliance disclosure, then transfers mid-conversation to agent B, which must resume without re-asking a single answered question and without dropping the disclosure state. Then break it on purpose. Show the trace when the caller interrupts during the disclosure, when they hang up and call back four minutes later, and when the upstream model times out. Write up which failure mode you could not design away and why.
A cold email that works at Sela
What Sela screens for
Costanoa and Emergence are both enterprise-software specialists, not generalist AI tourists, and the stated reason for leading was revenue attribution rather than cost savings. That tells you what gets rewarded internally: work that moves funded loans. The hiring window is the interesting part. Going 17 to 50 means the next thirty-odd people set the engineering culture permanently, and three of the open roles still carry the word 'Founding' at $10M+ ARR, which does not last. Five roles went live on announcement day. If you want a founding title at a company that already has six of the ten largest customers in its category, this is a narrow window, and it is open right now.
Tailor your CV to the specific Sela role rather than sending a general one. Applications that mirror the language of the job description clear automated filters at a materially higher rate.
Don't make these mistakes
Generic enthusiasm about voice AI. Nate spent years as a data scientist at LinkedIn and then co-founded VoiceOps, a company built entirely on mining sales-call conversation data; Vahe was a senior ML engineer and tech lead at Google with a Cambridge PhD and a Berkeley Lab postdoc. Telling either of them that voice agents are having a moment is telling them what they already sold. Also skip the latency benchmark pitch. Sub-second response is table stakes they already ship, and their differentiation is explicitly behavioral, learned sales behavior applied consistently, plus TCPA compliance inside the agent. Lead instead with a specific failure you have seen in a regulated, multi-turn sales conversation: where the agent lost context on a transfer, mishandled a compliance disclosure, or optimized a call-completion metric that had nothing to do with whether the deal funded.
Mistakes that kill Sela applications
Don't send the same CV you sent everywhere else. At people it's obvious, and it's the fastest rejection there is.
