Score History
Timeline events are AI-curated from public reporting. Score trajectory is derived from documented events.
Levels.fyi launches as a bare-bones static HTML page comparing career levels across big tech companies, built in coffee shops by two friends who spotted the same question recurring on Blind. Zero monetization, zero tracking, zero login requirements. Infrastructure costs are literally less than a cup of coffee per year, hosted on AWS S3 with Google Sheets as the database. The only revenue model is organic traffic from answering forum questions.
The founders go full-time after Levels.fyi crosses $500K ARR, monetizing primarily through Triplebyte hiring referral commissions. CNBC coverage in June 2019 establishes the platform as an authoritative salary data source. The first End of Year Pay Report launches, and crowdsourced salary data begins attracting over 50,000 data points. The product remains fully open-access with no login requirement, but Triplebyte-style referral monetization introduces mild misaligned incentives as the platform earns revenue from hiring placements.
Levels.fyi raises its first outside funding (seed round from Adapt Ventures and others), launches a mobile app, and begins selling crowdsourced salary data to employers for $1,200/month, sparking controversy on Hacker News about conflicts of interest. The platform launches negotiation coaching ($750+), career coaching, a community forum, and a job board ($700+/month for employers). New revenue streams multiply but each one deepens the two-sided data exploitation model where users contribute for free and employers pay for access.
The mid-2023 sign-up wall marked the clearest break from Levels.fyi's open-access origins, requiring account creation to view salary data points that were previously freely browsable. Advertising presence increased, session replay tracking expanded to include FullStory and Microsoft Clarity, and terms of service hardened with mandatory arbitration, a class action waiver, and a $100 liability cap. The platform now serves 3 million monthly users across 200+ job titles but increasingly monetizes the audience through enterprise data resale, coaching upsells, and third-party advertising.
Alternatives
Anonymous professional community with salary data, company reviews, and verified employee discussions. Covers similar tech industry compensation data with stronger anonymity protections. Easy switch — just sign up with a work email. Scored 42 here (Actively Enshittifying), higher than Levels.fyi but offers richer workplace discussion context.
Broader employer review platform with salary data, company reviews, and interview questions across all industries. Much larger dataset but increasingly enshittified (scored 57 here). Requires contributing content to access reviews via its 'give-to-get' policy. Easy switch but expect more friction and dark patterns.
Established compensation data platform with salary surveys and benchmarking tools used by both individuals and HR teams. Covers a wider range of industries beyond tech. Easy switch — free salary report available after completing a survey. Less tech-focused than Levels.fyi but more comprehensive for non-tech roles.

Levels.fyi launches as static HTML side project
Zuhayeer Musa and Zaheer Mohiuddin launch Levels.fyi as a simple static HTML page comparing software engineer career levels across big tech companies like Google, Microsoft, and Facebook. Built in coffee shops with hosting costs 'less than a cup of coffee a year,' the site runs on standard HTML/JS/CSS hosted on AWS S3 with Google Sheets as a backend.
Levels.fyi launches on Product Hunt
The platform launches on Product Hunt in September 2017, gaining initial traction beyond the Blind forum community where the founders had been seeding links to answer leveling comparison questions. Early growth is entirely organic via forums and recruiter word-of-mouth.
Triplebyte referral partnership begins monetization
Levels.fyi establishes a commission-based referral partnership with Triplebyte, earning revenue for every user hired through the platform. This is the first monetization channel, aligning user interests (finding jobs) with the business model. Monthly revenue reaches approximately $5,000 by mid-2018.
Comp.fyi spin-off launches for compensation data
The founders launch Comp.fyi on Product Hunt as a dedicated compensation data tool, after realizing how popular the salary information was on the original Levels.fyi leveling comparison site. This marks the beginning of the platform's shift from pure leveling data to comprehensive compensation tracking.
Dice covers Levels.fyi job offer comparison tool
Dice.com publishes coverage of Levels.fyi's offer comparison capabilities, broadening the platform's reach beyond the Blind and Hacker News communities to the wider tech job-seeker audience. The platform gains credibility as a resource for comparing job offers across companies.
CNBC feature boosts platform visibility and credibility
CNBC publishes a detailed article on how big tech companies like Google and Facebook set salaries, prominently featuring Levels.fyi data showing a Level 3 at Google earns approximately $189,000 in total compensation. This mainstream media coverage significantly increases the platform's visibility and positions it as an authoritative source for tech compensation data.
Bootstrapped revenue crosses $500K ARR
Levels.fyi's bootstrapped startup crosses $500K annual recurring revenue, as reported on Indie Hackers. The founders achieve this milestone while keeping infrastructure costs minimal by running the entire platform on Google Sheets as a backend and static HTML hosted on AWS S3.
Levels.fyi and Candor joint salary negotiation AMA on Hacker News
Levels.fyi co-hosts an Ask Me Anything session on Hacker News with Candor (a salary negotiation service), discussing salary negotiation strategies and compensation transparency. This partnership foreshadows Levels.fyi's eventual launch of its own negotiation coaching service.
First End of Year Pay Report published for 2019
Levels.fyi publishes its inaugural End of Year Pay Report ranking the highest-paying tech companies by career level. The annual report becomes a signature content piece that drives massive traffic and media coverage, while establishing the platform's editorial authority over which companies and roles get highlighted.
Verified Salary Stream launches with W2 and offer letter verification
Levels.fyi launches Salary Stream, a bi-weekly digest of verified salaries confirmed via uploaded W2 forms, offer letters, and pay statements. The announcement states 'Accurate pay data is non-existent publicly. That changes today.' This creates a two-tier data system: self-reported (free to submit) and verified (requires document upload).
Negotiation coaching service launches at $750+ per engagement
Levels.fyi introduces its salary negotiation service, pairing users with former tech company recruiters who provide 1-on-1 coaching during offer negotiations. Initial pricing starts around $750 per engagement with a money-back guarantee if the user doesn't see a compensation increase. This marks the platform's first high-margin paid consumer service.
Self-reported data bias concerns surface on Hacker News
A Hacker News discussion highlights that Levels.fyi data is 'heavily biased toward companies where tech is their primary business,' with self-reported salaries suspected to skew high due to self-selection bias. Users with high compensation are more likely to report, while those with average salaries stay silent. The platform's claimed 85-90% accuracy rate applies only to verified submissions, which are a fraction of total data.
Fast Company profiles Levels.fyi on salary transparency mission
Fast Company publishes a feature article describing how Levels.fyi 'decodes the shadowy levels used by tech companies to classify jobs' and helps tech workers get the pay they deserve. The article highlights the founders' bootstrapped journey and positions the platform as a transparency advocate. By this point the platform serves over 1 million monthly users.
Levels.fyi hosts Hacker News AMA on salary data methodology
The founders conduct a public AMA on Hacker News titled 'We're Levels.fyi, the most accurate resource for tech salaries, ask us anything,' fielding questions about data accuracy, verification methods, and the platform's growth. This transparency exercise is notable given the later shift toward less open communication about methodology.
Seed funding round from Adapt Ventures and others
Levels.fyi raises an undisclosed seed round from Adapt Ventures, Browder Capital, Datapower Ventures, Founders Inc, and Gauntlet Ventures. This is the company's first outside funding after being bootstrapped to profitability. The investment signals a shift from lean bootstrapped operation to growth-oriented startup, bringing investor expectations for returns.
Mobile app launches on iOS and Android
Levels.fyi launches its mobile app on both iOS App Store and Google Play, bringing salary comparison data to mobile users. The app introduces mandatory onboarding flows that will later receive complaints for confusing or forced interactions, including reports of blank screens after the 'get started' prompt.
HN post reveals Levels.fyi selling user salary data to employers for $1,200/month
A Hacker News 'Tell HN' post titled 'Levels.fyi is selling your salary data to companies for $1200/month' sparks controversy. Critics highlight the conflict of interest: the platform simultaneously helps users negotiate higher salaries while selling the same crowdsourced data to employers for compensation benchmarking. Founder Zaheer responds that the data is already publicly accessible, framing the enterprise product as a convenience feature rather than exclusive access.
Career coaching service expands beyond negotiation
Levels.fyi announces career coaching as a new paid service, expanding beyond salary negotiation into general career guidance. After a pilot program with 20+ individuals, the service launches with a network of 10+ coaches who are active industry professionals rather than full-time career coaches. This further diversifies the platform's paid services.
Community forum launches with waitlist-gated access
Levels.fyi launches a community discussion forum, initially with waitlist-gated access. Users on Blind discuss waiting months for community access. The forum is positioned to compete with Blind's anonymous workplace discussions, adding engagement features that increase time-on-site and data collection opportunities.
2022 pay report: 150,000+ salary submissions collected
Levels.fyi publishes its 2022 End of Year Pay Report, revealing the platform collected over 150,000 salary submissions that year across thousands of companies. The report expands beyond software engineering to cover engineering management, product management, product design, and hardware engineering roles. European and Asian salary data is included for the first time.
Blog post on California pay transparency law impact
Levels.fyi publishes analysis of California's SB 1162 pay transparency law that took effect January 1, 2023, requiring employers with 15+ employees to include salary ranges in job postings. The company positions itself to integrate legally mandated salary ranges into its job board, benefiting from the regulatory tailwind of increasing pay transparency mandates across states.
Job board launches with compensation-based filtering
Levels.fyi launches a job board with inline total compensation estimates, filtering by compensation range, level, benefits, company size, and more. Job postings start at $700/month for employers. The job board adds another revenue stream from employers while creating additional user data collection touchpoints via job application tracking.
Mandatory sign-up wall blocks free access to salary data
Levels.fyi implements a mandatory sign-up requirement to view individual salary data points that were previously freely accessible without login. Users on Blind describe this as the platform 'going the way of Glassdoor and sacrificing user experience,' comparing it to Glassdoor's trajectory of progressive access restrictions. Defenders argue the login requirement helps prevent AI scrapers from harvesting data.
Users predict escalation toward premium paywall services
In the same Blind thread about the sign-up wall, users predict that the login gate is 'step one to email spam to get you to sign up for premium services,' anticipating further monetization of the user base through upselling. Community members draw explicit parallels to Glassdoor's enshittification trajectory of progressive data lockdown.
Custom GPT data leak exposes salary dataset via OpenAI
A Levels.fyi team member creates a custom GPT using OpenAI's GPT builder with a subset of salary data as a knowledge source. Users quickly discover they can extract the raw data file, which includes base salaries, stock vesting schedules, and applicant gender information. The leaked data covers submissions from 2021. Co-founder Zuhayeer Musa publicly acknowledges the incident and warns to 'treat any data you upload to OpenAI as good as public.'
2023 pay report: 200,000+ submissions across expanding role types
Levels.fyi publishes its 2023 End of Year Pay Report, announcing the collection of over 200,000 salary submissions across thousands of companies. The report is described as 'our most robust' yet, expanding further beyond software engineering into additional engineering disciplines and management roles.
Community discussions highlight growing ad presence on site
A Levels.fyi community thread titled 'How Levels is making money' surfaces concerns about increasing advertising on the platform. While the team responds that they haven't placed ads 'all over the place,' users note the growing presence of promoted content and employer-sponsored listings interspersed with organic salary data.
AI engineer compensation report reveals proprietary data analysis
Levels.fyi publishes its first dedicated AI Engineer Compensation Trends report, showing median AI engineer salaries peaking at $295,000 in March 2024. The report demonstrates the platform's expansion into specialized compensation analytics, but the methodology behind how data points are filtered, weighted, and presented remains proprietary.
Negotiation coaching prices increase to $1,250-$5,000 per engagement
Levels.fyi's negotiation coaching service now charges $1,250 for the Standard package, $2,500 for Premium, and $5,000 for the Leadership tier. These prices have increased from the initial ~$750 launch price. Each tier guarantees a minimum compensation increase ($5K/$10K/$20K respectively) with a money-back refund if the threshold isn't met.
Gender pay gap report published using platform data
Levels.fyi publishes a Gender Pay Gap Report showing women represent only 16% of US salary data submissions (below the 24% STEM workforce representation), with the compensation gap widening at senior levels. The report demonstrates the platform's editorial influence on public discourse while raising questions about representativeness of its self-reported dataset.
Privacy policy confirms interest-based advertising data sharing
Levels.fyi's privacy policy discloses that the platform works with third-party advertising companies for interest-based advertising purposes, does not respond to Do Not Track signals, and uses session replay technologies (FullStory and Microsoft Clarity) that record user clicks, mouse movements, scrolls, and keystrokes. The policy states the company 'cannot offer any assurances' about the effectiveness of advertising opt-out mechanisms.
Terms of service include $100 liability cap and mandatory arbitration
Levels.fyi's terms of service cap aggregate company liability at $100, require mandatory binding arbitration for all disputes, include a class action waiver with only a 30-day opt-out window, and disclaim responsibility for coaching advice provided by independent contractor coaches. These provisions significantly limit user legal recourse.
Platform reveals Google Sheets backbone scaled to 10M cells
Levels.fyi publishes a blog post revealing the platform scaled to millions of users with Google Sheets as its backend database, eventually hitting the 10 million cell limit. Rather than migrating to a traditional database, the team initially sharded across multiple sheets. The post provides transparency into the platform's technical infrastructure but also reveals the inherent limitations of data validation when the entire dataset was stored in spreadsheets.
Platform expands to 200+ job titles across multiple industries
Levels.fyi's 2024 End of Year Pay Report reflects expansion to over 200 job titles across industries beyond just software engineering, including product management, data science, hardware engineering, product design, and mechanical engineering. The platform now claims over 2.5 million monthly users.
Mobile app infrastructure migrated from deprecated Microsoft AppCenter
Levels.fyi migrates its mobile app's over-the-air update system from Microsoft AppCenter (sunsetting March 31, 2025) to a self-hosted, serverless OTA pipeline. The move reflects the company's philosophy of owning infrastructure while optimizing for performance, but also means more direct control over what gets pushed to user devices without app store review.
AI engineer compensation premium narrows at junior levels, widens at senior
Levels.fyi's Q3 2025 AI Engineer Compensation Trends report shows the AI vs. non-AI pay premium narrowing to 6.2% at entry level (down from 10.7%) but widening to 18.7% at staff level (up from 15.8%). The report drives significant traffic and establishes the platform as an authoritative voice on AI compensation trends.
Mobile app complaints about forced onboarding and blank screens
Google Play reviews document complaints about the Levels.fyi mobile app forcing users through a 'get started' onboarding flow that leads to blank screens. Users report being unable to access salary data without completing the mandatory sign-up process, with some reviews describing the experience as broken and frustrating.
Pave reaches $1.6B valuation as enterprise comp data competitor
Pave, Levels.fyi's primary competitor in enterprise compensation benchmarking, closes a financing round at a $1.6 billion valuation from Index Ventures and a16z. CB Insights explicitly identifies Levels.fyi as a Pave competitor, underscoring the increasingly competitive enterprise salary data market that pressures Levels.fyi to expand its employer-facing revenue streams.
