Best Startups to Work For in 2026 — The Curated List for Job Seekers

How this list was built

We started with the public universe of ~4,500 US and Europe-based startups that have raised a Series A or later since Q1 2024 (Pitchbook + Crunchbase). We filtered for companies with more than 25 open engineering, product, or design roles on their careers page — a hard signal that hiring plans are real, not aspirational. From the ~600 companies that cleared that filter, we removed anyone with an average Glassdoor rating below 3.8, anyone with public reports of unpaid or delayed compensation in the last 12 months, and anyone whose most recent round was a down-round of more than 30% (a rough proxy for stress on the cap table that materially impacts new-hire equity outcomes).

The remaining ~180 companies were reviewed manually by our editorial team, cross-referenced against Levels.fyi total-comp data, LinkedIn headcount growth trajectories, and public sentiment on communities like Blind, Hacker News, and Twitter. The list below is our top selections across the categories that we believe will define the 2026 hiring cycle: applied AI, developer tools, fintech infrastructure, climate and energy, health tech, and horizontal SaaS. Where a category is currently dominated by a small number of standout companies, we list them all rather than force a ranking.

This list is refreshed quarterly. If you believe we missed a company that meets the criteria above, or if you have information (positive or negative) about a company on the list that should change our assessment, use the feedback link at the bottom of this guide. We read every submission.

Applied AI — the category defining 2026 hiring

Applied AI is the largest single hiring category in 2026, accounting for roughly 40% of net new startup engineering roles in the US per LinkedIn's H2 2025 workforce report. The category has bifurcated into three sub-segments: foundation-model companies (OpenAI, Anthropic, Mistral, xAI), AI-native product companies building on top of those foundations, and AI infrastructure companies serving both. The best jobs for most candidates are in the second and third groups, where equity grants remain meaningful and scope is broader.

Anthropic (San Francisco / London / New York) — approximately 900 employees, actively hiring across research, engineering, product, and go-to-market. Anthropic has raised more than $15B in total funding through 2025 and is broadly considered the most capital-rich and mission-aligned of the frontier labs outside of OpenAI. Compensation is at or above FAANG staff-level bands for equivalent roles. On our list because the technical bar and mission clarity are unusually high for a company at this scale.

Perplexity (San Francisco) — approximately 300 employees, series E at roughly $18B valuation. The company has become the default AI-native search product for a large and growing user base and is expanding aggressively into commerce and enterprise. On our list because it is one of the few AI-native consumer companies with durable, verified user traction and a clear moat in query understanding.

Cursor / Anysphere (San Francisco) — approximately 100 employees, series C at roughly $9B valuation. The AI-native code editor has become the default tool for a meaningful percentage of professional developers in under 24 months. On our list because it demonstrates the fastest product-led growth curve of any developer tool in our tracking history, and because equity for early hires is materially undervalued at the current valuation.

Sierra (San Francisco) — approximately 200 employees, series C. Enterprise-focused AI agents for customer service, founded by Bret Taylor (former co-CEO Salesforce, chair of OpenAI) and Clay Bavor (former VP Google). On our list because founder-market fit is exceptional and the enterprise sales motion is repeatable.

Harvey (San Francisco / London) — approximately 250 employees, series D at roughly $5B valuation. Legal-vertical AI with adoption inside the majority of AmLaw 100 firms. On our list because vertical AI companies with real enterprise contracts are rare, and the moat compounds with each additional firm.

Glean (Palo Alto) — approximately 700 employees, series F at roughly $7.2B valuation. Enterprise search and work assistant that has become the default AI layer inside a large number of Fortune 500 companies. On our list because the ARR growth rate is verified and among the fastest of any B2B AI company we track.

Developer tools — where the best engineers are still going

Developer tools remains a durable category because the buyers (developers) are the same people making the hiring decisions at the companies building the tools. This produces unusually strong culture-fit compounding: the best devtools companies attract the best engineers, who then build better tools, who attract more of the best engineers. The category is also structurally cash-efficient — devtools companies typically reach $10M ARR with fewer than 40 employees.

Vercel (San Francisco / remote) — approximately 700 employees, series E at roughly $3.25B valuation, profitable on a cashflow basis. The default deployment platform for Next.js and increasingly for AI-native applications. On our list because remote-first culture is genuinely mature (not aspirational), engineering process is public and well-documented, and equity refresh grants at Vercel are among the most consistent we track.

Linear (San Francisco / remote) — approximately 100 employees, series C. Issue tracking that has become the standard at a large and growing share of Series A–C startups. On our list because product taste is unmatched in the category, hiring bar is deliberately narrow, and the company has never done a layoff.

Turso (remote-first) — approximately 40 employees, series A. Edge-database company built on libSQL. On our list because the technical bet (SQLite at the edge for AI workloads) has become the default architecture for the fastest-growing AI-native applications, and because the company is genuinely remote-first from day one.

Warp (San Francisco) — approximately 80 employees, series B. AI-native terminal that has become the default replacement for iTerm and Terminal.app for a large share of professional developers. On our list because the founding team's second act after Google is producing an unusually opinionated product.

Modal (New York / remote) — approximately 60 employees, series B. Serverless GPU infrastructure that has become the default runtime for a large share of AI startups. On our list because the founder is one of the most respected voices in ML infrastructure and the compensation bands are above the NYC market for equivalent roles.

Supabase (remote-first, global) — approximately 100 employees, series C at roughly $2B valuation. Open-source Firebase alternative built on Postgres. On our list because the remote-first operating system is one of the most refined we've seen, the product-led growth motion is real and verified, and equity at series C remains meaningful.

Fintech infrastructure — the durable slice of a shrinking category

Consumer fintech has been the worst-performing venture category on a returns basis for three consecutive years, but fintech infrastructure (the plumbing beneath consumer apps and banks) has continued to grow. The companies below are all B2B, all serving either banks, credit unions, or other fintechs, and all have public revenue traction that supports their current valuations.

Ramp (New York) — approximately 1,000 employees, series D at roughly $13B valuation. Corporate cards, expense management, and increasingly a full spend-management platform. On our list because revenue growth has remained above 100% year-over-year at scale, and because Ramp's engineering brand attracts an unusually strong candidate pool.

Mercury (San Francisco) — approximately 700 employees, series C at roughly $3.5B valuation. Banking for startups and small businesses that has become the default choice for the majority of new venture-backed companies. On our list because Mercury has weathered the SVB collapse better than any peer and has emerged with a materially stronger competitive position.

Modern Treasury (San Francisco / remote) — approximately 200 employees, series C. Payment operations infrastructure for enterprises and large fintechs. On our list because the founding team is deeply technical, the remote-first culture is genuinely mature, and the ARR base is diversified across hundreds of enterprise customers.

Persona (San Francisco) — approximately 500 employees, series C at roughly $1.5B valuation. Identity verification and KYC infrastructure. On our list because the product has become the default identity layer for a large share of consumer fintechs and marketplaces, producing unusually sticky ARR.

Climate and energy — the highest-conviction bet in 2026 venture

Climate and energy is now the second-largest venture category by capital deployed after AI, per Pitchbook's 2025 report. Unlike the 2007–2012 cleantech cycle, this generation of climate startups is anchored in provable unit economics, government-backed offtake agreements (IRA, EU Green Deal), and enterprise customers with net-zero mandates. The engineering talent bar in this category has risen dramatically as senior engineers migrate from big tech.

Commonwealth Fusion Systems (Cambridge, MA) — approximately 900 employees, private, roughly $2B raised across multiple rounds. Fusion energy demonstration facility scheduled for grid connection later this decade. On our list because the technical bet has cleared each major milestone on the published timeline and the compensation is at parity with FAANG for equivalent engineering seniority — genuinely rare in hardware.

Boston Metal (Boston) — approximately 150 employees, series C. Molten oxide electrolysis for zero-emissions steel production. On our list because the pilot facility is now producing verified output at commercial-relevant scale and the customer pipeline includes multiple Fortune 500 steel buyers.

Charm Industrial (San Francisco) — approximately 100 employees, series B. Bio-oil sequestration for permanent carbon removal. On our list because the company has delivered more verified tons of durable carbon removal than any other permanent CDR startup and has offtake contracts with Frontier, Stripe, and Microsoft.

Twelve (Berkeley, CA) — approximately 300 employees, series C. CO2 electrolysis producing industrial chemicals and sustainable aviation fuel. On our list because the SAF product has offtake agreements with multiple major airlines and the underlying science has been validated in third-party peer-reviewed publications.

Form Energy (Berkeley, CA / Somerville, MA) — approximately 500 employees, series F. Iron-air multi-day battery storage for grid-scale applications. On our list because the first commercial deployment came online in 2024 and utility contracts have expanded materially since.

Health tech — quiet, capital-efficient, and durable

Health tech in 2026 looks nothing like health tech in 2021. The bar for revenue traction before a Series B is now materially higher, and the survivors are companies with real payer contracts, real provider adoption, or real drug-development milestones. The companies below all have durable revenue and are hiring meaningfully.

Abridge (Pittsburgh / San Francisco) — approximately 300 employees, series D at roughly $2.75B valuation. Ambient AI scribe used by more than 100 health systems. On our list because the health-system adoption curve is the fastest we've tracked in enterprise health tech, and the technical bar is genuinely high for a category that most people expect to commoditize.

Xaira Therapeutics (South San Francisco) — approximately 200 employees, private, $1B seed round. AI-native drug discovery. On our list because the founding team combines Foundation Medicine, Illumina, and Stanford ML lineage — one of the strongest founding teams in AI biotech.

Isomorphic Labs (London) — approximately 300 employees, private (Alphabet portfolio). AI drug discovery spinout from DeepMind. On our list because access to AlphaFold-derived tooling combined with Big Pharma partnership pipeline (Novartis, Eli Lilly) makes it one of the best positioned AI biotechs in the world.

Devoted Health (Waltham, MA) — approximately 3,000 employees, private at roughly $12.6B valuation. Vertically integrated Medicare Advantage insurer. Larger than most other companies on this list, but included because the engineering org is still hiring at Series-B pace and the mission-driven talent density is unusually high.

Horizontal SaaS — the boring category that still ships careers

Horizontal SaaS is out of fashion with venture but remains the highest hit-rate category for durable career outcomes. The companies below are all growing ARR at above 40% year-over-year at scale, are all cash-flow positive or on a clear path there, and are all hiring across engineering, product, and go-to-market.

Notion (San Francisco) — approximately 800 employees, series C. Documents, wiki, and increasingly a workspace AI platform. On our list because the enterprise motion has genuinely accelerated in the last 24 months and the company has remained capital-efficient at scale.

Figma (San Francisco / remote) — approximately 1,700 employees, private, IPO expected. Design platform. On our list because post-Adobe-merger-collapse the company has emerged with cleaner strategy, and because engineering compensation is at parity with FAANG.

Canva (Sydney / remote) — approximately 5,000 employees, private at roughly $37B valuation, revenue at approximately $3B ARR. Design for everyone else. Larger than most others on this list but included because global remote hiring is real and the equity refresh cadence is one of the most consistent we track.

Airtable (San Francisco / remote) — approximately 700 employees, series F. Application platform for teams that outgrew spreadsheets. On our list because the AI-native product update in 2025 has re-accelerated growth in enterprise and because compensation bands remain highly competitive.

Retool (San Francisco) — approximately 300 employees, series C at roughly $3.2B valuation. Internal tools platform. On our list because it is one of the most cash-efficient B2B companies at its scale we've tracked, and because the engineering bar is deliberately narrow.

How to evaluate any startup that isn't on this list

This list is a starting point, not an endpoint. Roughly 90% of the great startup jobs available in 2026 are at companies that are not on any published list — because the best companies fill 60% of their hires from network referrals before a role ever hits their public careers page. If you are only looking at curated lists, you are competing for the least differentiated slots.

The framework we use when evaluating a startup that isn't on our list has four questions. First: is the company at a stage where employee equity is materially different from cash? For most candidates, that means seed through Series B; by Series C+, cash comp becomes the dominant component of total compensation and the equity math rarely justifies the risk. Second: does the founding team have a specific, non-generic advantage in this market? Third: is the runway more than 12 months, and has the last round's plan actually been executed against? Fourth: can you find at least two current employees willing to talk to you unstructured, without the founder in the room?

If all four are yes, the company deserves the same depth of research as any name on our list. Read the last board deck if you can get it. Model the equity three ways (5×, 1×, 0). Talk to two former employees on LinkedIn. Ask the founder the questions that require a real answer, not a pitch. This is your career; the person on the other side of the table is asking you to bet 2–4 years of it. Diligence proportionally.
