Nextdoor sits on the intersection of neighbors, native companies, and group belief – so success can’t be measured with one metric. Artem Kofanov, Finance & Technique Lead at Nextdoor, builds choice programs that align product, information science, and go-to-market round sturdy market outcomes. His work has helped scale hyperlocal demand and monetization programs that generated 100,000+ certified leads for service professionals and delivered 50% discount in common Price-per-Click on for advertisers – whereas sustaining belief and high quality guardrails throughout a multi-sided community.
Your work spans natural discovery, lead technology, and paid instruments. How do you outline success?
I outline success as sturdy outcomes throughout a multi-sided ecosystem. In my function main monetization finance & technique at Nextdoor – and as a juror for the 2025 ECDMA World Awards – I’ve evaluated tons of of approaches, and those that final persistently steadiness consumer belief and utility with enterprise outcomes. If you happen to win on one facet whereas degrading the opposite, you’re borrowing from the long run. My job is to design the principles, metrics, and rollout gates that preserve the system economically robust and reliable because it scales.
To try this, I exploit what I name a Cross-Sided Metric Stack (CSMS): a measurement system that displays the ecosystem as an entire reasonably than remoted efficiency indicators, and that ties on to go/no-go scaling choices. CSMS is designed to forestall the commonest market failure mode – native metric wins that quietly erode belief, long-run retention, or true advertiser ROI.
On the neighbor facet, I observe outcomes tied to relevance, belief, and utility. Relevance asks whether or not we present the proper native info on the proper second. Belief is protected by means of guardrails like conceal price and unfavourable suggestions – early indicators that content material is changing into noisy or exploitative. Utility is measured not by clicks, however by whether or not the interplay helped remedy an actual native want.
On the enterprise facet, the main focus shifts to natural worth and predictable ROI. Natural worth exhibits up in suggestions, mentions, and Business Web page exercise – the belief layer that drives native decision-making. ROI predictability is assessed by means of certified leads, direct contacts, and booked initiatives or jobs, particularly for service suppliers.
Lastly, I have a look at system integrity: retention and repeat worth on either side, plus market variety and long-term well being, to keep away from a system that solely works for a slender slice of contributors. My guiding rule is straightforward: if neighbors or companies really feel exploited, the economics ultimately fail – even when short-term metrics look robust.
You’re in product finance and technique. What does that truly imply in observe?
I function as a strategist and inner investor, and as a thought companion to product and engineering leaders. Reasonably than pondering when it comes to transport particular person options, I deal with funding and scaling programs. Which means asking what we’re underwriting, what must be confirmed, and what constraints are required to maintain the system wholesome over time.
In observe, this begins with understanding intent by figuring out what neighbors and companies try to perform and what’s lacking within the present product expertise. From there, I translate these insights right into a enterprise case that clearly lays out potential upside, dangers, and completely different eventualities. A vital a part of the work is securing purchase in and resourcing by aligning management, unlocking headcount, and sequencing investments based mostly on anticipated return. I additionally outline cross-sided success by connecting enterprise outcomes, neighbor outcomes, and when related, service skilled outcomes right into a single measurement body. As soon as an initiative is dwell, I spend important time interrogating efficiency, in search of indicators of silent demand and hidden friction that aren’t instantly seen in headline metrics.
There are concrete examples of this strategy in observe. In some instances, neighbors desire a service however don’t notice they will remedy that want on Nextdoor. When the system nudges responsibly and avoids spamming, it might create a real triple win. Neighbors get assist quicker, service professionals obtain certified demand, and the platform turns into extra helpful and trusted.
That’s the reason I describe this work as inner investor work. It goes past evaluation and facilities on choice making underneath uncertainty, with actual accountability for outcomes.
Alternative Alerts is a brand new lead technology product for house providers. What was the primary problem?
The primary problem was not mistaking a product launch for proof of viability. Alternative Alerts started as a speculation to attach house service professionals with potential purchasers in actual time. The tougher query emerged after that preliminary success: whether or not the mannequin would nonetheless work when scaling from tons of of customers to 1000’s, as competitors elevated and actual world complexity inevitably appeared.
To reply this, we relied on what I name Proof-Bar Scaling Gates (EBSG) – a disciplined strategy to scaling constructed round pre-defined situations. That is moveable to any market product the place early traction can masks high quality decay at scale. We established which metrics wanted to enhance, which of them needed to stay secure, and which indicators would point out that high quality was starting to decay and that the system ought to be paused, fastened, or redesigned earlier than additional enlargement. This construction allowed us to maneuver ahead intentionally reasonably than counting on floor stage enhancements. For instance, we solely expanded when lead quantity elevated with out deterioration in high quality indicators, resembling match price and shut price – so scale by no means got here on the expense of belief.
Finally, the product scaled from an preliminary speculation right into a sturdy lead market that served a significant variety of service suppliers with persistently high-quality initiatives – as a result of we handled scaling as a proof downside, not a launch downside. My function was end-to-end: I recognized the chance by means of aggressive evaluation and consumer analysis, sized the upside with a monetary mannequin, secured management alignment and headcount, and helped outline the experiment design and rollout gates that protected high quality as quantity elevated. I view this consequence primarily as affirmation that the underlying mannequin might stand up to actual operational load, not simply produce a short-term spike in outcomes.
You’ve beforehand pushed investments in hyper‑native search. Why is it so essential for service professionals?
We generated multiple hundred thousand certified leads for service professionals whereas holding belief and high quality guardrails on the core of the system. The best way we did it’s by treating hyperlocal search not as a rating widget, however as a funnel that strikes from intent to contact – as a result of in native contexts, urgency, proximity, and offline constraints dominate consumer habits. This strategy is moveable to any offline-constrained market – native providers, healthcare entry, or any class the place velocity and reliability matter greater than searching.
Which means paying shut consideration to how intent is captured by means of each express and implicit indicators, how matching works throughout natural and industrial surfaces, and the way success is measured by means of financial outcomes reasonably than easy click on exercise. When matching genuinely displays proximity and actual availability, {the marketplace} turns into extra environment friendly. Service professionals spend much less time chasing nonproductive leads, neighbors obtain dependable assist quicker, and belief will increase as a result of the system feels useful reasonably than extractive.
The rationale that issues is that it improves real-world market effectivity: shoppers discover dependable assist quicker, and repair professionals cut back wasted time on low-intent demand – so {the marketplace} turns into more healthy because it scales.
AI is now in all places in marketplaces. Why isn’t “adding algorithms” sufficient – and what does it take to make ML drive sturdy outcomes?
As a result of and not using a clear choice making structure and express financial constraints, optimization tends to break down into native metric enhancements that don’t maintain up on the system stage. One of the crucial essential initiatives I led addressed precisely this downside by means of the cross useful integration of technique, finance, information science, and product operations right into a single optimization framework. In lots of organizations these obligations sit in separate groups, which is usually why profitable experiments fail to translate right into a sturdy affect on P&L.
I designed the choice structure for a unified optimization playbook that linked yield administration and advert pricing with ROI measurement and scaling choices. The novelty is that it closes the hole between experiment-level wins and sturdy P&L affect by forcing express choice guidelines: what proof is required to scale, what guardrails should maintain, and when to pause or roll again. Quantitatively, this framework drove roughly a ~50% discount in common cost-per-click (CPC), enhancing effectivity for advertisers whereas decreasing irrelevant advert publicity for neighbors. The aim was to shut the hole between what seems to be good inside an experiment and what really works at scale for the broader ecosystem. My function in constructing this method was finish to finish and nearer to that of an inner investor than a standard operator. I outlined the product thesi, secured engineering sources utilizing ROI based mostly enterprise instances, and labored intently with information science to ascertain the monitoring and measurement wanted to guage outcomes. In parallel, I partnered with product management to tell useful resource allocation, rollout guardrails, and deployment standards, and authored the underlying methodology, together with choice guidelines, guardrails, and approval standards for scaling modifications.
Importantly, this was not AI applied for its personal sake. The framework produced measurable affect on either side of the market. For advertisers and businesses, spend was redirected away from low high quality clicks towards visitors that truly converts, which prolonged budgets and improved predictability. For neighbors, the system diminished the variety of irrelevant adverts and elevated publicity to helpful affords from close by companies.
You created an SMB worth segmentation framework and a price‑creation funnel. What’s it, and the way did it change technique?
I noticed that “SMB” isn’t a single buyer kind – the worth drivers differ dramatically by class, enterprise maturity, and the way neighbors categorical demand. So I constructed a segmentation framework that maps the place worth is created and what should be true for that worth to scale.
At a excessive stage, I take into consideration this as a price creation funnel that connects the total buyer journey. It begins with natural presence and belief, mirrored in Business Web page exercise, suggestions, and mentions. From there, it strikes into engagement, which exhibits whether or not companies return and take part in a significant manner. The following layer is activation, specializing in which merchandise companies undertake, whether or not that’s lead technology, paid instruments, or a mixture of each. This then ties on to true outcomes resembling certified leads, booked jobs or initiatives, and repeatable ROI. Lastly, retention exhibits whether or not the worth created early on continues over time reasonably than fading after preliminary exercise.
What made this framework actionable is that it functioned as greater than a descriptive taxonomy. It turned a technique software that helped reply concrete questions. It allowed us to see which segments have been underneath monetized or over monetized relative to their general well being, the place market well being reasonably than lacking options was the true limiting issue, and which segments required completely different approaches to onboarding, measurement, or guardrails to be able to develop sustainably.
This framework turned an working software to prioritize product technique and useful resource allocation based mostly on how worth is created in every section – not simply the place income occurs to be right this moment. It gave cross-functional groups a shared language for onboarding, measurement, and guardrails, so we might scale monetization with out degrading market belief.
How do you consider what’s correlation vs. causation – and the way do you keep away from “growth” that’s actually cannibalization throughout merchandise?
The aim right here is easy: to keep away from funding initiatives except there’s credible proof they create incremental worth. Which means utilizing randomized experiments when attainable – and when not, utilizing disciplined quasi-experimental strategies with clear assumptions – so we don’t confuse correlation, substitution, or cannibalization for true development.
I depend on three layers of rigor in my work. The primary is lifecycle analytics that observe the total business trip from begin to end. I construct cohort based mostly views that observe how the expertise evolves over time reasonably than focusing solely on early activation. Within the case of Alternative Alerts, this meant taking a look at indicators resembling whether or not companies obtain sufficient alternatives to remain engaged, whether or not neighbors reply at significant charges, and whether or not these alternatives flip into actual connections. This made it attainable to see the place the system was breaking down, whether or not in onboarding, matching high quality, demand availability, or conversion mechanics.
The second layer is causal measurement that helps separate actual sign from noise. Each time attainable, I depend on outcomes from randomized experiments. When that isn’t possible, or when results play out over longer time horizons, I exploit quasi experimental approaches. These embody matched cohort and propensity type comparisons to regulate for self choice into options, in addition to regression frameworks with fastened results and controls to isolate class and seasonality results.
The third layer is a portfolio stage view that accounts for cannibalization throughout the ecosystem. In multi product programs, a characteristic can seem profitable whereas merely shifting habits reasonably than creating new worth. This may present up as substitution between paid and natural channels, between lead technology and paid instruments, or as quick time period conversion good points that come on the expense of long run retention. To deal with this, I exploit a portfolio type framework that focuses on the web new worth created throughout the ecosystem, distinguishes between shifting demand and producing demand, and evaluates outcomes over longer home windows reasonably than slender seven to 14 day results.
That mixture – lifecycle cohorts, causal inference, and cannibalization evaluation – is what lets us make funding choices which can be grounded, not simply thrilling.
What’s your signature strategy on this discipline?
I construct cross-sided choice programs that fund incremental ecosystem worth – not vainness development. In observe, meaning two repeatable frameworks: a Cross-Sided Metric Stack (CSMS) to outline outcomes and belief guardrails, and Proof-Bar Scaling Gates (EBSG) to set the proof threshold for when one thing is able to scale.
