The Cheapest Way to Grow Your Book Is to Stop Losing the Customers You Already Have

Stephanie Mier studied theater and acting at Arizona State. She needed a job flexible enough to leave by 2pm for auditions, and found one at Bristol West running a twelve-week trainee program. She opened her first policy and fell in love with it — her words, not an exaggeration. Insurance, she says, was the math that finally made sense to her.

From there the career reads like a tour of the auto-and-insurance intersection: property casualty, wrongful death claims, then twelve years ago a leadership role running the western division of a TPA out of Arizona under Wilson Wheeler, a 45-year industry veteran who remains her mentor today. Then Turo, building out the claims department for the peer-to-peer car-sharing company. Then Fair Financial under Scott Painter, combining policy and leasing with Uber as the anchor client, until Fair was acquired by Shift. She tried founding her own brokerage during the pandemic — too early, by her own admission, to the embedded-insurance wave that followed. Along the way she also underwrote a Bitcoin-backed auto-repair policy for a Japanese blockchain company, learning the hard way how difficult it is to reconcile crypto-denominated deposits with dollar-denominated claims.

Consulting is what finally led her to ServiceUp. She was advising a team that had since moved on from a company called Kite, focused almost entirely on fleet business, with no real insurance practice. She told them there was a $40 billion TAM they were leaving on the table. Three weeks later, co-founder Brett Carlson was at her door with no defined role to offer — just an invitation to help go after it.

In Episode 141 of InsurTechTalk, Stephanie and I covered what ServiceUp actually does, why direct repair networks have a transparency problem nobody talks about, and why retention — not acquisition — is the real economics of the insurance business.

About Stephanie Mier

Stephanie Mier is the Chief Insurance Officer at ServiceUp, an all-in-one repair platform for vehicles ranging from personal cars to Class 1–3 medium- and heavy-duty fleets, with a recent expansion into RVs. ServiceUp was founded during the pandemic by co-founders Brett Dash and Brett Carlson, who started by personally driving damaged vehicles to pre-negotiated repair shops for friends before building it into a company. It has since raised a $55 million Series B led by Peakspan, grown from 17 to more than 125 employees, and expanded from 3 to 52 metropolitan markets across the US, including Hawaii. Before ServiceUp, Stephanie held claims and leadership roles at a regional TPA, Turo, and Fair Financial.

The DoorDash Model for Auto Repair

ServiceUp’s pitch is straightforward once you hear it: insurance claims involving vehicle damage generate an enormous amount of coordination — pickup, repair, parts, communication, drop-off — that nobody has built proper infrastructure for.

• ServiceUp handles the full logistics chain: picking up the vehicle, delivering it to a partner shop, managing collision and comprehensive repairs and third-party property damage claims, and returning the vehicle when it’s done
• The customer gets a tracker not unlike a pizza delivery app — car received, torn down, estimated completion date, ready for pickup at a time that actually works for them
• On the carrier side, ServiceUp serves insurers, MGAs, brokerages, and TPAs, aiming to lower cycle times and cut the rental-day leakage that comes from slow repairs
• Pricing is typically 10–15% below what a customer would pay walking into a shop directly, and ServiceUp uses its repair data to help carriers underwrite more accurately — flagging saturated markets, OEM-versus-aftermarket (LKQ) part patterns, and similar signals
• A parallel fleet-side business serves rental car companies, HVAC fleets, and medium-to-heavy-duty operators, with the same logistics engine focused on minimizing what Stephanie calls “utilization drag” — vehicles sitting idle instead of earning

How the Portal Replaces the Phone Call

The operational core of ServiceUp is a portal that gives adjusters full visibility without a single phone call to a body shop.

• Photos, estimates, supplement requests, disputes, and diminished-value questions all live in one text-like thread instead of getting chased down by phone
• Labor rates are preset and fixed across ServiceUp’s shop network — no variation by shop, which means a carrier’s average cost of repair stops fluctuating month to month
• Partner shops operate under strict SLAs: under 24 hours to tear down a vehicle after receipt, under 24 hours to respond to any supplement or question
• Estimates are written against audit rules baked into the carrier’s own policy guidelines, so adjusters aren’t re-reviewing every line for correctness
• Regional Ops Managers load-balance across a pool of 50 to 150 shops per market, routing each vehicle to the shop actually equipped for that repair — EV-certified, heavy-duty capacity, frame work — rather than whichever shop is simply next in line

Beyond Indemnity

Several pieces of the ServiceUp product exist specifically to remove friction that traditional claims processes tolerate.

• Every repair carries a lifetime warranty; if a customer is unsatisfied, ServiceUp takes the vehicle back and makes it right, sometimes with a detail job or a gas card as a goodwill gesture that goes beyond strict indemnity
• ServiceUp offers deductible financing for policyholders who can’t cover their deductible upfront — a segment Stephanie notes is growing as deductibles rise industry-wide
• The platform writes UPD (unrelated prior damage) estimates on the carrier’s behalf, documenting pre-existing damage unrelated to the current loss so carriers aren’t exposed to double-dipping on a later claim
• Vehicles are quality-checked four times in a single cycle: at pickup, at shop drop-off, at repair completion, and at final delivery back to the customer
• ServiceUp also supports subrogation directly and partners with TPAs to triage recovery-eligible files quickly, since speed is the biggest lever in subrogation recovery rates

The Clear Cover Partnership

Clear Cover has been involved with ServiceUp’s insurance vertical from the beginning — not just as a customer, but as a design partner. Stephanie credits Kyle, Aaron Wheaten, and Brandon, Clear Cover’s senior director of damage, with shaping product decisions and workflow updates alongside ServiceUp’s own team from early on. Every one of Clear Cover’s adjusters — whether the active count is 35 or 250 — is provisioned into the portal directly, with no ceiling on how the partnership scales.

Origin Story: Two Co-Founders and a Pandemic Garage

ServiceUp started because Brett Dash had a damaged vehicle and started driving cars to pre-negotiated repair shops for friends during the pandemic, using labor rates he’d worked out himself. It scaled from a favor into an obvious business. He partnered with Brett Carlson, who brought a sales background from years at larger companies, and a third early co-founder who has since moved on to other ventures. The three built the initial tech and portal and launched in the Bay Area.

Four years later: a $55 million Series B led by Peakspan, more than 60 established partnerships, 125-plus employees, and 52 markets — up from 3 at launch.

Why Transparency Is the Whole Business

Stephanie’s closing argument ties the entire product back to a single economic idea: retaining a policyholder is dramatically cheaper than acquiring a new one, and the claims experience is the moment that decides whether that customer stays.

• Most of the friction in a bad claims experience comes down to a lack of transparency — not knowing where your car is, what’s being repaired, or what it will cost
• A policyholder treated like they matter during a claim tells their friends about it — word-of-mouth retention that no acquisition channel can match on cost
• The same logic applies to fleets: business interruption isn’t abstract when a driver is down a vehicle mid-shift, and predictable, transparent turnaround is what prevents that interruption from compounding
• ServiceUp’s differentiation isn’t really about repair logistics — it’s about treating every insured like, in Stephanie’s words, an A-grade customer, regardless of claim size

Key Takeaways

• ServiceUp’s core insight is economic, not technical: retention is cheaper than acquisition, and the claims experience is the highest-leverage retention moment insurers have
• Direct repair networks have existed for decades, but most lack the tech layer to give carriers real-time visibility — that gap, not the shop relationships themselves, is what ServiceUp sells
• Preset labor rates and strict shop SLAs remove the cost and time variability that make claims severity hard to forecast
• UPD estimates and four-point QC checkpoints protect carriers from disputes and double-dipping without adding friction for the customer
• Deductible financing is a small feature with outsized retention value as deductibles climb industry-wide
• ServiceUp’s fastest path to scale has been through deep design partnerships with carriers like Clear Cover, not just distribution deals
