QC Growth is the best overall alternative to Belkins for seed-stage startups. It delivers the core services people compare Belkins alternatives on, outbound campaigns and qualified meetings, and adds the ICP, messaging and CRM work a seed team usually hasn't built yet. It works on a monthly retainer starting at $7,500 per month. Belkins is a strong agency for mid-market teams that already know who buys. Seed founders tend to hit a different set of limits: a reported 3–6 month minimum, a 4–6 week ramp and a model priced around meeting volume. QC Growth publishes this guide, so we're on the list. Every competitor detail below comes from that company's own site or a named third-party review, linked where we cite it.
Belkins is a B2B appointment-setting and lead generation agency. Its core service is email-first outbound run by the Belkins team on the client's behalf: a sales audit, market sizing, prospect research, copywriting, scheduling and reporting.
It is one of the most visible names in outsourced sales development, helped by a large library of outbound and sales content. Third-party reviews describe its best fit as mid-market SaaS with deal sizes above $5,000 (Miniloop). For that buyer, one appointment-setting price roundup lists a Belkins starter package from $5,000 a month with 100 guaranteed appointments a year (RevenueFlow).
If your ICP converts and your sales team needs more first calls, that is a reasonable trade.
The limits show up earlier in a company's life, when the founder is still the only person closing deals.
QC Growth is the best overall alternative to Belkins.
It covers most comparable service areas, works on a monthly retainer model starting at $7,500 per month, and delivers an embedded team inside your own tools, operators who have sold your category, and a GTM system you keep when the engagement ends.
QC Growth is an embedded GTM team for Seed to Series A B2B software companies. Our clients usually have product-market-fit signal and a handful of deals the founder closed personally. What they lack is a repeatable sales motion, and the runway to hire a senior in-house team to build one.
We place a fractional pod inside your stack: a top-1% GTM operator, a GTM lead, a GTM engineer and BDR support. The pod builds and runs Allbound, our name for inbound, outbound and partner channels working from one set of signals. Strategy, outbound infrastructure, messaging, campaigns and reporting all sit with the same team.
Our verticals are devtools and open source, AI, healthtech (through our QCHC Growth division) and deep tech. More than 50 portfolio companies have worked with us, including Netlify, Gatsby, Turso, Mastra AI and Grafbase.
Our operators carried the bag in the categories our clients sell into. Luke Bivens sold at Gatsby through its acquisition by Netlify, and before that at Workpop. Aron Schuhmann sold at MightyAI (acquired by Uber), Gatsby and OctoAI (acquired by NVIDIA). Shane O'Connor ran a 10x ARR stretch at Scalar after roles at Tyk and SmartBear, and Kori Bivens, a former VP at RVO Health with 10+ years in healthcare, leads QCHC Growth.
Targeting runs on signal stacking. An account enters a sequence when several signals line up, such as a new VP of Engineering, a hiring spike and a pricing-page visit. That keeps outreach to developers and clinicians infrequent and relevant.
Everything we build lives in your accounts: domains, sequences, Clay tables, CRM fields and dashboards. Grafbase CEO Fredrik Björk says QC "helped us land our first enterprise customers and find product-market fit." Burn Media Co. grew revenue from $142,000 in April to $181,000 in August, up 27.5% and its best two months on record.
QC Growth packages run $7,500 to $25,000 a month depending on scope, over 6–12 month engagements. The top of the range covers a full fractional GTM team. Standard retainers carry no equity, and every engagement starts with a free growth audit.
Most seed founders who outgrow Belkins are missing the system behind the meetings. QC Growth builds that system with operators who have sold your category, then leaves it with your team. Among the providers on this list, it is the one option that pairs vertical operators with full-motion execution and infrastructure you own.
ColdIQ builds and runs outbound and LinkedIn programs inside accounts its clients own. It reports 300+ clients and $50M+ in ARR generated for them. It also sells a GTM data API, pulling from 40+ data providers, that teams can call from Claude Code and other AI agents.
The managed service runs on dated milestones: a first play live within 14 days and three plays running by day 45.
ColdIQ is one of the faster-moving outbound shops in the category, and it publishes its launch timeline. Clients keep every account, prompt and playbook, which answers a common complaint about appointment-setting agencies. Its AirOps case study reports $7.83M in qualified pipeline and $1.52M closed-won over 10 months.
Scoped per client. The monthly fee is billed separately from third-party software costs, with a 90-day initial term.
ColdIQ is a smart choice for teams whose ICP already converts and whose bottleneck is outbound volume. Founders still working out who buys will need positioning help outside its focus, which narrows the fit for most seed-stage teams.
CIENCE combines outsourced SDR teams with graph8, its own data and intent software. Outreach runs across email, calling, LinkedIn, display ads and content syndication.
The company operates a three-brand family (CIENCE services, graph8 and Tenbound), which gives it more scale than most firms on this list. Its pitch is a hybrid of AI-assisted targeting and human SDRs.
CIENCE is one of the few appointment-setting firms with its own data layer. Third-party reviews report pricing from about $2,900 to $20,000+ a month, a $5,000 setup fee reduced to $2,500 for startups, and roughly $250 per held meeting on performance pricing (Miniloop).
Roughly $2,900 to $20,000+ a month plus a setup fee, per third-party reviews. Performance pricing is reported at about $250 per held meeting.
CIENCE fits teams that want data and execution bundled, with a few low-cost ways in. Seed founders should weigh the 6–12 month full-service term against their runway, since volume targeting pays off best on an ICP that's already proven.
Martal Group provides fractional SDR teams that run email, LinkedIn and phone outreach, drawing on a bench of 200+ fractional reps. One published roundup lists monthly output ranges of 3,000–5,000 prospects targeted, 9,000–12,000 emails sent and 20–30 qualified prospects (RevenueFlow).
Engagements start with a pilot before moving to a subscription.
Martal is one of the larger multichannel options, and its pilot gives buyers a defined trial period before a longer commitment. Its published activity ranges also make it easier to compare against other volume providers.
Quoted per client, after a 3–4 month pilot.
Martal suits teams that know their buyer and want broad multichannel reach. At seed, a 3–4 month pilot built around activity volume can outrun an ICP that hasn't been tested yet.
Leadium is a US-based outbound agency that runs cold email and calling with dedicated SDRs, custom data and managed sequencing. It markets itself with ROI figures and sells mostly to B2B sales teams that want meetings booked for their closers.
Leadium is one of the more accessible dedicated-SDR options. Pricing is reported at about $3,000 to $8,000 a month, scaled per SDR seat or per qualified appointment (Miniloop).
About $3,000 to $8,000 a month, per seat or per appointment, according to third-party reviews.
Leadium works for teams that need meetings and already know who to target. It doesn't take on the strategy or systems work a seed team usually lacks, so it fits better once the ICP is settled.
memoryBlue has run outsourced SDR programs for B2B tech companies since 2002. It acquired Operatix in 2023 to cover EMEA, and it pairs SDR pods with recruiting and training so clients can move reps in-house later.
It is rated 4.7/5 on Clutch across 23 reviews (Real Good GTM).
memoryBlue is one of the most established names in tech sales development. Its build-then-hire path appeals to companies that want an outsourced program now and an internal team later.
Quote only, with a reported minimum above $5,000 a month.
memoryBlue suits funded tech companies that want an SDR program they will eventually own. Seed teams without a proven message may pay for that structure before they need it.
SalesRoads provides dedicated, US-based SDRs for B2B appointment setting. The company states its SDRs average 14 years in B2B sales and offers month-to-month terms.
SalesRoads is one of the few firms in the category that publishes a price: $11,950 per four weeks for one SDR, with cancel-anytime terms (RevenueFlow). That makes it easy to budget and easy to stop.
$11,950 per four weeks per SDR, which works out to about $13,000 a month.
SalesRoads is a solid pick when flexibility and rep seniority matter most. At about $13,000 a month for one rep, most seed teams will get more from a pod that also builds the system the rep works inside.
Sales Xceleration provides fractional VPs of Sales. Founded in 2013, it reports 225+ advisors across the US, Canada, the UK and Australia, and more than 8,000 businesses served.
It reports average first-year sales increases of 20–32% for clients.
Sales Xceleration is one of the largest fractional sales leadership networks. For a company whose gap is management of an existing team, a part-time VP covers more ground than an appointment-setting retainer.
Quoted per engagement.
Sales Xceleration fits an SMB that has reps and needs leadership. A seed startup with no team yet needs someone to build and run the motion, which a single fractional leader can't cover alone.
Kalungi is a B2B SaaS marketing agency, founded in 2018, that works as an outsourced marketing department: a fractional CMO plus content, demand generation and RevOps. Its programs follow T2D3 ("triple, triple, double, double, double"), a five-year SaaS growth model.
A competitor's comparison page reports 150+ B2B SaaS clients and a HubSpot-centered stack (Growigami). Another review places its sweet spot at $1M–$5M ARR, post product-market fit (SaaS Hero).
For teams whose gap sits on the marketing side, Kalungi covers the whole function with one SaaS-specific playbook. It is a sensible option when inbound demand, positioning and attribution matter more than outbound meetings.
Full-service engagements are reported at $15,000 to $25,000 a month on 6–12 month terms (Growigami). Another review lists a $25,000 project minimum and a $45,000-a-month full-service tier (SaaS Hero).
Kalungi is a reasonable pick for post-PMF SaaS teams that need marketing run for them. Seed teams still closing founder-led deals usually need sales-side execution first, and its price floor sits above most seed budgets.
Winning by Design is a revenue consulting and training company founded in 2012. It created the SPICED qualification method (Situation, Pain, Impact, Critical Event, Decision) and the Bowtie model, which maps the customer journey from first touch through renewal and expansion.
Its typical client is a SaaS company with $5M–$100M in ARR and a sales team of 20–200 reps, according to Oliv. Clients include DocuSign, Adobe and MURAL.
For a team whose problem is inconsistent execution across existing reps, Winning by Design gives everyone one method and one vocabulary. Many sales leaders already know SPICED, which shortens onboarding for new hires.
About $1,500 per individual contributor and $2,500 per leader or facilitator, per Oliv. A 50-rep rollout lands near $87,500.
Winning by Design fits scale-ups training an existing sales org. A seed founder with no reps yet needs someone to build and run the motion first, and the training becomes useful once there's a team to train.
You closed the first customers yourself and the pipeline stalls whenever you go back to product. QC's pod takes over prospecting, sequencing and first calls, and coaches you through the enterprise deals that still need a founder in the room. Grafbase and Eraser.io both credit QC with landing their first enterprise customers.
Developers punish spray-and-pray outreach, and a burned domain is hard to recover. QC times outreach to real usage signals, such as GitHub activity or package installs, and adds dev-friendly motions like technical advisory boards and webinars. The operators running it sold at Gatsby, OctoAI and Scalar, so the messaging comes from people who have sold to engineers.
Every enterprise inbox already gets AI pitches. QC builds a narrative per ICP that holds up in procurement, targets accounts with a real trigger and budget, and puts senior operators on the enterprise cycle next to the founder. Mastra AI, ZeroEntropy and Crescendo are among the AI companies QC has worked with; Crescendo COO Zack Urlocker says "the fractional sales team model changed everything for us."
Provider and payer deals run 9–18 months on trust, and generic appointment setting can burn credibility in a market where reputation travels. QCHC Growth is led by Kori Bivens, a former VP at RVO Health, and works through advisory councils, clinical networks and conference-season signals. The division reports 40+ healthcare clients over 10+ years.
If a previous campaign booked meetings with the wrong people, the fix sits upstream in ICP, signals and messaging. QC starts with a growth audit of what the last program targeted and what converted. From there, the pod rebuilds the ICP, warms fresh domains and relaunches with fewer, better-matched accounts.
A seed company and a Series B company need different things from an agency. Before ICP is proven, look for a partner that tests segments and messaging. After it's proven, volume becomes the lever.
Domains, sequences, enrichment workflows, CRM fields and dashboards should live in your accounts. When they do, your first GTM hire starts on a working system instead of an empty CRM.
Outreach to developers, ML teams or hospital executives reads differently from generic B2B copy. Ask who on the team has sold to your buyer before, and by name.
Funding rounds, hiring, job changes, product usage and web visits tell you which accounts are in market this month. A partner that stacks those signals contacts fewer accounts and wastes less of your TAM.
Published pricing and a minimum term you can afford matter more at seed than at any later stage. Compare the full commitment, setup fees included, against the months of runway it consumes.
If your ICP converts and your closers have open calendars, an appointment-setting firm such as Leadium or SalesRoads can fill them. If the founder is still the only closer, start with the system: ICP, signals, messaging and a CRM that shows what works.
Reported minimums on this list range from none (SalesRoads) to 3–4 months (Martal), 3–6 months (Belkins) and 6–12 months (CIENCE full service, Kalungi, QC Growth). Multiply the monthly fee by the minimum and compare it with your remaining runway.
Before signing, ask the provider to draft the first three emails for one real target account. You'll see within a page whether they understand your buyer.
Write down who owns the sending domains, the data, the sequences and the dashboards when the engagement ends. If it isn't in the contract, assume it leaves with the agency.
QC Growth's estimate for a senior in-house GTM team is $57,000 to $81,000 a month plus 1.25% to 2.75% in equity, before a quarter or more of recruiting and ramp. Our in-house vs fractional GTM cost breakdown shows the full math.
Set leading indicators before launch: infrastructure live by day 30, reply rates by ICP segment by day 60, and pipeline by source by day 90. Checkpoints make it clear early whether the partner is working.
QC Growth embeds operators who have sold devtools, AI and healthtech products inside your stack. They run a signal-stacked Allbound motion, and the domains, data and playbooks stay yours when the engagement ends. Packages start at $7,500 a month, against the $57,000 or more a month an equivalent in-house team costs.
We built QC for technical founders at Seed to Series A who have closed the first deals themselves and need a repeatable engine before the next raise. A free growth audit reviews your ICP, messaging, signals and stack, and shows the two moves we'd make first.
Belkins is used for B2B appointment setting and outbound lead generation, run by its team on the client's behalf. The service covers a sales audit, market sizing, prospect research, email copywriting, scheduling and reporting. Third-party reviews describe its best fit as mid-market SaaS with deal sizes above $5,000.
The best Belkins alternatives in 2026 are QC Growth, ColdIQ and CIENCE, followed by Martal Group, Leadium, memoryBlue, SalesRoads, Sales Xceleration, Kalungi and Winning by Design. QC Growth embeds a GTM pod for $7,500 to $25,000 a month and suits seed-stage startups that need the whole motion built. ColdIQ puts a first outbound play live within 14 days, and CIENCE bundles SDRs with its own data from about $2,900 a month.
When choosing a Belkins alternative, look for stage fit, infrastructure you keep, messaging written by people who know your buyer, signal-based targeting and a minimum term your runway can absorb. Reported minimums on this list run from none at SalesRoads to 6–12 months for full-service retainers. Ask every provider who owns the domains, data and sequences when the contract ends.
To choose the best Belkins alternative for your needs, first decide whether you need more meetings or a system that produces them. Teams with a proven ICP can buy volume from firms like Leadium at about $3,000 a month. Teams where the founder is still the only closer usually get more from an embedded pod such as QC Growth at $7,500 to $25,000 a month. Ask for a sample sequence and 30, 60 and 90-day checkpoints before signing.
Switching from Belkins to another provider is moderately easy once the minimum term ends, with most of the work in data and domains. Reviews cite 3–6 month minimums, so check your end date first. New sending domains typically need 4–6 weeks of warm-up before campaigns run at full volume. Export your contact lists, sequences and meeting history before the contract closes.
ColdIQ is better than Belkins for teams that want to own their outbound infrastructure and see a dated launch plan, with a first play live within 14 days. Belkins is the more established choice for email-first appointment setting with guaranteed appointment packages, reported from $5,000 a month. Neither focuses on ICP or positioning work, which seed-stage teams often still need.
The main difference between ColdIQ and Belkins is ownership: ColdIQ builds outbound systems inside accounts the client owns, while Belkins runs appointment setting for the client. ColdIQ prices per client with a 90-day initial term. Belkins is reported at $3,000 to $15,000 a month with a 3–6 month minimum.
Belkins is worth it for a seed-stage startup once the ICP is proven and the bottleneck is meeting volume. Before that, a 3–6 month minimum at up to $15,000 a month can commit $90,000 to meetings the founder may not convert. Seed teams usually get more from building ICP, signals and infrastructure first.
Belkins costs roughly $3,000 to $15,000 a month, according to third-party reviews, with a 3–6 month minimum commitment. One price roundup lists a starter package from $5,000 a month with 100 guaranteed appointments a year. For comparison, a dedicated US-based SDR at SalesRoads costs $11,950 per four weeks, and CIENCE's performance pricing is reported at about $250 per held meeting.
